Config.php Parameters
ownCloud uses the config/config.php file to control server operations.
config/config.sample.php lists all the configurable parameters within
ownCloud, along with example or default values. This document provides a more
detailed reference. Most options are configurable on your Admin page, so it
is usually not necessary to edit config/config.php.
Note
The installer creates a configuration containing the essential parameters.
Only manually add configuration parameters to config/config.php if you need to
use a special value for a parameter. Do not copy everything from
config/config.sample.php . Only enter the parameters you wish to modify!
ownCloud supports loading configuration parameters from multiple files.
You can add arbitrary files ending with .config.php in the config/
directory, for example you could place your email server configuration
in email.config.php. This allows you to easily create and manage
custom configurations, or to divide a large complex configuration file
into a set of smaller files. These custom files are not overwritten by
ownCloud, and the values in these files take precedence over config.php.
Default Parameters
These parameters are configured by the ownCloud installer, and are required
for your ownCloud server to operate.
This is a unique identifier for your ownCloud installation, created
automatically by the installer. This example is for documentation only,
and you should never use it because it will not work. A valid instanceid
is created when you install ownCloud.
‘instanceid’ => ‘d3c944a9a’,
The salt used to hash all passwords, auto-generated by the ownCloud
installer. (There are also per-user salts.) If you lose this salt you lose
all your passwords. This example is for documentation only, and you should
never use it.
'trusted_domains' =>
array (
'demo.example.org',
'otherdomain.example.org',
),
Your list of trusted domains that users can log into. Specifying trusted
domains prevents host header poisoning. Do not remove this, as it performs
necessary security checks.
'datadirectory' => '/var/www/owncloud/data',
Where user files are stored; this defaults to data/ in the ownCloud
directory. The SQLite database is also stored here, when you use SQLite.
(SQLite is not available in ownCloud Enterprise Edition)
The current version number of your ownCloud installation. This is set up
during installation and update, so you shouldn’t need to change it.
Identifies the database used with this installation. See also config option
supportedDatabases
- Available:
- sqlite (SQLite3 - Not in Enterprise Edition)
- mysql (MySQL/MariaDB)
- pgsql (PostgreSQL)
- oci (Oracle - Enterprise Edition Only)
Your host server name, for example localhost, hostname,
hostname.example.com, or the IP address. To specify a port use
hostname:####; to specify a Unix socket use
localhost:/path/to/socket.
The name of the ownCloud database, which is set during installation. You
should not need to change this.
The user that ownCloud uses to write to the database. This must be unique
across ownCloud instances using the same SQL database. This is set up during
installation, so you shouldn’t need to change it.
The password for the database user. This is set up during installation, so
you shouldn’t need to change it.
Prefix for the ownCloud tables in the database.
Indicates whether the ownCloud instance was installed successfully; true
indicates a successful installation, and false indicates an unsuccessful
installation.
Default config.php Examples
When you use SQLite as your ownCloud database, your config.php looks like
this after installation. The SQLite database is stored in your ownCloud
data/ directory. SQLite is a simple, lightweight embedded database that
is good for testing and for simple installations, but for production ownCloud
systems you should use MySQL, MariaDB, or PosgreSQL.
<?php
$CONFIG = array (
'instanceid' => 'occ6f7365735',
'passwordsalt' => '2c5778476346786306303',

1 => 'studio',
),
'datadirectory' => '/var/www/owncloud/data',
'dbtype' => 'sqlite3',
'version' => '7.0.2.1',

'dbuser' => 'oc_carla',
'dbpassword' => '67336bcdf7630dd80b2b81a413d07',
'installed' => true,
);
User Experience
These optional parameters control some aspects of the user interface. Default
values, where present, are shown.
'default_language' => 'en',
This sets the default language on your ownCloud server, using ISO_639-1
language codes such as en for English, de for German, and fr for
French. It overrides automatic language detection on public pages like login
or shared items. User’s language preferences configured under “personal ->
language” override this setting after they have logged in.
Set the default app to open on login. Use the app names as they appear in the
URL after clicking them in the Apps menu, such as documents, calendar, and
gallery. You can use a comma-separated list of app names, so if the first
app is not enabled for a user then ownCloud will try the second one, and so
on. If no enabled apps are found it defaults to the Files app.
'knowledgebaseenabled' => true,
true enables the Help menu item in the user menu (top right of the
ownCloud Web interface). false removes the Help item.
'enable_avatars' => true,
true enables avatars, or user profile photos. These appear on the User
page, on user’s Personal pages and are used by some apps (contacts, mail,
etc). false disables them.
'allow_user_to_change_display_name' => true,
true allows users to change their display names (on their Personal
pages), and false prevents them from changing their display names.
'remember_login_cookie_lifetime' => 60*60*24*15,
Lifetime of the remember login cookie, which is set when the user clicks the
remember checkbox on the login screen. The default is 15 days, expressed
in seconds.
'session_lifetime' => 60 * 60 * 24,
The lifetime of a session after inactivity; the default is 24 hours,
expressed in seconds.
'session_keepalive' => true,
Enable or disable session keep-alive when a user is logged in to the Web UI.
Enabling this sends a “heartbeat” to the server to keep it from timing out.
'skeletondirectory' => '/path/to/owncloud/core/skeleton',
The directory where the skeleton files are located. These files will be
copied to the data directory of new users. Leave empty to not copy any
skeleton files.
'user_backends' => array(
array(
'class' => 'OC_User_IMAP',
'arguments' => array('{imap.gmail.com:993/imap/ssl}INBOX')
)
),
The user_backends app (which needs to be enabled first) allows you to
configure alternate authentication backends. Supported backends are:
IMAP (OC_User_IMAP), SMB (OC_User_SMB), and FTP (OC_User_FTP).
'lost_password_link' => 'https://example.org/link/to/password/reset',
If your user backend does not allow to reset the password (e.g. when it’s a
read-only user backend like LDAP), you can specify a custom link, where the
user is redirected to, when clicking the “reset password” link after a failed
login-attempt.
Mail Parameters
These configure the email settings for ownCloud notifications and password
resets.
'mail_domain' => 'example.com',
The return address that you want to appear on emails sent by the ownCloud
server, for example oc-admin@example.com, substituting your own domain,
of course.
'mail_from_address' => 'owncloud',
FROM address that overrides the built-in sharing-noreply and
lostpassword-noreply FROM addresses.
'mail_smtpdebug' => false,
Enable SMTP class debugging.
'mail_smtpmode' => 'sendmail',
Which mode to use for sending mail: sendmail, smtp, qmail or
php.
If you are using local or remote SMTP, set this to smtp.
If you are using PHP mail you must have an installed and working email system
on the server. The program used to send email is defined in the php.ini
file.
For the sendmail option you need an installed and working email system on
the server, with /usr/sbin/sendmail installed on your Unix system.
For qmail the binary is /var/qmail/bin/sendmail, and it must be installed
on your Unix system.
'mail_smtphost' => '127.0.0.1',
This depends on mail_smtpmode. Specify the IP address of your mail
server host. This may contain multiple hosts separated by a semi-colon. If
you need to specify the port number append it to the IP address separated by
a colon, like this: 127.0.0.1:24.
This depends on mail_smtpmode. Specify the port for sending mail.
'mail_smtptimeout' => 10,
This depends on mail_smtpmode. This sets the SMTP server timeout, in
seconds. You may need to increase this if you are running an anti-malware or
spam scanner.
This depends on mail_smtpmode. Specify when you are using ssl or
tls, or leave empty for no encryption.
'mail_smtpauth' => false,
This depends on mail_smtpmode. Change this to true if your mail
server requires authentication.
'mail_smtpauthtype' => 'LOGIN',
This depends on mail_smtpmode. If SMTP authentication is required, choose
the authentication type as LOGIN (default) or PLAIN.
This depends on mail_smtpauth. Specify the username for authenticating to
the SMTP server.
'mail_smtppassword' => '',
This depends on mail_smtpauth. Specify the password for authenticating to
the SMTP server.
Proxy Configurations
The automatic hostname detection of ownCloud can fail in certain reverse
proxy and CLI/cron situations. This option allows you to manually override
the automatic detection; for example www.example.com, or specify the port
www.example.com:8080.
'overwriteprotocol' => '',
When generating URLs, ownCloud attempts to detect whether the server is
accessed via https or http. However, if ownCloud is behind a proxy
and the proxy handles the https calls, ownCloud would not know that
ssl is in use, which would result in incorrect URLs being generated.
Valid values are http and https.
'overwritewebroot' => '',
ownCloud attempts to detect the webroot for generating URLs automatically.
For example, if www.example.com/owncloud is the URL pointing to the
ownCloud instance, the webroot is /owncloud. When proxies are in use, it
may be difficult for ownCloud to detect this parameter, resulting in invalid
URLs.
'overwritecondaddr' => '',
This option allows you to define a manual override condition as a regular
expression for the remote IP address. For example, defining a range of IP
addresses starting with 10.0.0. and ending with 1 to 3:
^10\.0\.0\.[1-3]$
'overwrite.cli.url' => '',
Use this configuration parameter to specify the base URL for any URLs which
are generated within ownCloud using any kind of command line tools (cron or
occ). The value should contain the full base URL:
https://www.example.com/owncloud
The URL of your proxy server, for example proxy.example.com:8081.
The optional authentication for the proxy to use to connect to the internet.
The format is: username:password.
Deleted Items (trash bin)
These parameters control the Deleted files app.
'trashbin_retention_obligation' => 'auto',
If the trash bin app is enabled (default), this setting defines the policy
for when files and folders in the trash bin will be permanently deleted.
The app allows for two settings, a minimum time for trash bin retention,
and a maximum time for trash bin retention.
Minimum time is the number of days a file will be kept, after which it
may be deleted. Maximum time is the number of days at which it is guaranteed
to be deleted.
Both minimum and maximum times can be set together to explicitly define
file and folder deletion. For migration purposes, this setting is installed
initially set to “auto”, which is equivalent to the default setting in
ownCloud 8.1 and before.
Available values:
- auto
default setting. keeps files and folders in the trash bin for 30 days
and automatically deletes anytime after that if space is needed (note:
files may not be deleted if space is not needed).
- D, auto
keeps files and folders in the trash bin for D+ days, delete anytime if
space needed (note: files may not be deleted if space is not needed)
- auto, D
delete all files in the trash bin that are older than D days
automatically, delete other files anytime if space needed
- D1, D2
keep files and folders in the trash bin for at least D1 days and
delete when exceeds D2 days
- disabled
trash bin auto clean disabled, files and folders will be kept forever
'versions_retention_obligation' => 'auto',
If the versions app is enabled (default), this setting defines the policy
for when versions will be permanently deleted.
The app allows for two settings, a minimum time for version retention,
and a maximum time for version retention.
Minimum time is the number of days a version will be kept, after which it
may be deleted. Maximum time is the number of days at which it is guaranteed
to be deleted.
Both minimum and maximum times can be set together to explicitly define
version deletion. For migration purposes, this setting is installed
initially set to “auto”, which is equivalent to the default setting in
ownCloud 8.1 and before.
Available values:
- auto
default setting. Automatically expire versions according to expire
rules. Please refer to Files_versions online documentation for more
info.
- D, auto
keep versions at least for D days, apply expire rules to all versions
that are older than D days
- auto, D
delete all versions that are older than D days automatically, delete
other versions according to expire rules
- D1, D2
keep versions for at least D1 days and delete when exceeds D2 days
- disabled
versions auto clean disabled, versions will be kept forever
ownCloud Verifications
ownCloud performs several verification checks. There are two options,
true and false.
'appcodechecker' => true,
Checks an app before install whether it uses private APIs instead of the
proper public APIs. If this is set to true it will only allow to install or
enable apps that pass this check.
Check if ownCloud is up-to-date and shows a notification if a new version is
available.
'has_internet_connection' => true,
Is ownCloud connected to the Internet or running in a closed network?
'check_for_working_webdav' => true,
Allows ownCloud to verify a working WebDAV connection. This is done by
attempting to make a WebDAV request from PHP.
'check_for_working_wellknown_setup' => true,
Allows ownCloud to verify a working .well-known URL redirects. This is done
by attempting to make a request from JS to
https://your-domain.com/.well-known/caldav/
'check_for_working_htaccess' => true,
This is a crucial security check on Apache servers that should always be set
to true. This verifies that the .htaccess file is writable and works.
If it is not, then any options controlled by .htaccess, such as large
file uploads, will not work. It also runs checks on the data/ directory,
which verifies that it can’t be accessed directly through the Web server.
'config_is_read_only' => false,
In certain environments it is desired to have a read-only configuration file.
When this switch is set to true ownCloud will not verify whether the
configuration is writable. However, it will not be possible to configure
all options via the Web interface. Furthermore, when updating ownCloud
it is required to make the configuration file writable again for the update
process.
Logging
'log_type' => 'owncloud',
By default the ownCloud logs are sent to the owncloud.log file in the
default ownCloud data directory.
If syslogging is desired, set this parameter to syslog.
Setting this parameter to errorlog will use the PHP error_log function
for logging.
'logfile' => '/var/log/owncloud.log',
Log file path for the ownCloud logging type.
Defaults to [datadirectory]/owncloud.log
Loglevel to start logging at. Valid values are: 0 = Debug, 1 = Info, 2 =
Warning, 3 = Error, and 4 = Fatal. The default value is Warning.
'syslog_tag' => 'ownCloud',
If you maintain different instances and aggregate the logs, you may want
to distinguish between them. syslog_tag can be set per instance
with a unique id. Only available if log_type is set to syslog.
The default value is ownCloud.
'log.condition' => [
'shared_secret' => '57b58edb6637fe3059b3595cf9c41b9',
'users' => ['sample-user'],
'apps' => ['files'],
],
Log condition for log level increase based on conditions. Once one of these
conditions is met, the required log level is set to debug. This allows to
debug specific requests, users or apps
- Supported conditions:
- shared_secret: if a request parameter with the name log_secret is set to
this value the condition is met
- users: if the current request is done by one of the specified users,
this condition is met
- apps: if the log message is invoked by one of the specified apps,
this condition is met
Defaults to an empty array.
'logdateformat' => 'F d, Y H:i:s',
This uses PHP.date formatting; see http://php.net/manual/en/function.date.php
'logtimezone' => 'Europe/Berlin',
The default timezone for logfiles is UTC. You may change this; see
http://php.net/manual/en/timezones.php
Append all database queries and parameters to the log file. Use this only for
debugging, as your logfile will become huge.
Log successful cron runs.
'cron.lockfile.location' => '',
Location of the lock file for cron executions can be specified here.
Default is within the tmp directory. The file is named in the following way:
owncloud-server-$INSTANCEID-cron.lock
where $INSTANCEID is the string specified in the instanceid field.
Because the cron lock file is accessed at regular intervals, it may prevent
enabled disk drives from spinning down. A different location for this file
can solve such issues.
'log_rotate_size' => false,
Enables log rotation and limits the total size of logfiles. The default is 0,
or no rotation. Specify a size in bytes, for example 104857600 (100 megabytes
= 100 * 1024 * 1024 bytes). A new logfile is created with a new name when the
old logfile reaches your limit. If a rotated log file is already present, it
will be overwritten.
Alternate Code Locations
Some of the ownCloud code may be stored in alternate locations.
ownCloud uses some 3rd party PHP components to provide certain functionality.
These components are shipped as part of the software package and reside in
owncloud/3rdparty. Use this option to configure a different location.
For example, if your location is /var/www/owncloud/foo/3rdparty, then the
correct configuration is ‘3rdpartyroot’ => ‘/var/www/owncloud/foo/’,
If you have an alternate 3rdpartyroot, you must also configure the URL as
seen by a Web browser.
'customclient_desktop' =>
'http://owncloud.org/sync-clients/',
'customclient_android' =>
'https://play.google.com/store/apps/details?id=com.owncloud.android',
'customclient_ios' =>
'https://itunes.apple.com/us/app/owncloud/id543672169?mt=8',
This section is for configuring the download links for ownCloud clients, as
seen in the first-run wizard and on Personal pages.
Apps
Options for the Apps folder, Apps store, and App code checker.
'appstoreenabled' => true,
When enabled, admins may install apps from the ownCloud app store.
'appstoreurl' => 'https://api.owncloud.com/v1',
The URL of the appstore to use.
'appstore.experimental.enabled' => false,
Whether to show experimental apps in the appstore interface
Experimental apps are not checked for security issues and are new or known
to be unstable and under heavy development. Installing these can cause data
loss or security breaches.
'apps_paths' => array(
array(
'path'=> '/var/www/owncloud/apps',
'url' => '/apps',
'writable' => true,
),
),
Use the apps_paths parameter to set the location of the Apps directory,
which should be scanned for available apps, and where user-specific apps
should be installed from the Apps store. The path defines the absolute
file system path to the app folder. The key url defines the HTTP Web path
to that folder, starting from the ownCloud webroot. The key writable
indicates if a Web server can write files to that folder.
'appcodechecker' => true,
Checks an app before install whether it uses private APIs instead of the
proper public APIs. If this is set to true it will only allow to install or
enable apps that pass this check.
Previews
ownCloud supports previews of image files, the covers of MP3 files, and text
files. These options control enabling and disabling previews, and thumbnail
size.
'enable_previews' => true,
By default, ownCloud can generate previews for the following filetypes:
- Image files
- Covers of MP3 files
- Text documents
Valid values are true, to enable previews, or
false, to disable previews
The maximum width, in pixels, of a preview. A value of null means there
is no limit.
The maximum height, in pixels, of a preview. A value of null means there
is no limit.
'preview_max_scale_factor' => 10,
If a lot of small pictures are stored on the ownCloud instance and the
preview system generates blurry previews, you might want to consider setting
a maximum scale factor. By default, pictures are upscaled to 10 times the
original size. A value of 1 or null disables scaling.
'preview_max_filesize_image' => 50,
max file size for generating image previews with imagegd (default behaviour)
If the image is bigger, it’ll try other preview generators,
but will most likely show the default mimetype icon
Value represents the maximum filesize in megabytes
Default is 50
Set to -1 for no limit
'preview_libreoffice_path' => '/usr/bin/libreoffice',
custom path for LibreOffice/OpenOffice binary
'preview_office_cl_parameters' =>
' --headless --nologo --nofirststartwizard --invisible --norestore '.
'-convert-to pdf -outdir ',
Use this if LibreOffice/OpenOffice requires additional arguments.
'enabledPreviewProviders' => array(
'OC\Preview\PNG',
'OC\Preview\JPEG',
'OC\Preview\GIF',
'OC\Preview\BMP',
'OC\Preview\XBitmap',
'OC\Preview\MP3',
'OC\Preview\TXT',
'OC\Preview\MarkDown'
),

The following providers are enabled by default:
- OC\Preview\PNG
- OC\Preview\JPEG
- OC\Preview\GIF
- OC\Preview\BMP
- OC\Preview\XBitmap
- OC\Preview\MarkDown

- OC\Preview\StarOffice
LDAP
Global settings used by LDAP User and Group Backend
'ldapUserCleanupInterval' => 51,
defines the interval in minutes for the background job that checks user
existence and marks them as ready to be cleaned up. The number is always
minutes. Setting it to 0 disables the feature.
See command line (occ) methods ldap:show-remnants and user:delete
Maintenance
These options are for halting user activity when you are performing server
maintenance.
Enable maintenance mode to disable ownCloud
If you want to prevent users from logging in to ownCloud before you start
doing some maintenance work, you need to set the value of the maintenance
parameter to true. Please keep in mind that users who are already logged-in
are kicked out of ownCloud instantly.
When set to true, the ownCloud instance will be unavailable for all users
who are not in the admin group.
SSL
'openssl' => array(
'config' => '/absolute/location/of/openssl.cnf',
),
Extra SSL options to be used for configuration.
'enable_certificate_management' => false,
Allow the configuration of system wide trusted certificates
Memory caching backend configuration
Available cache backends:
- \OC\Memcache\APC Alternative PHP Cache backend
- \OC\Memcache\APCu APC user backend
- \OC\Memcache\ArrayCache In-memory array-based backend (not recommended)
- \OC\Memcache\Memcached Memcached backend
- \OC\Memcache\Redis Redis backend
- \OC\Memcache\XCache XCache backend
Advice on choosing between the various backends:
- APCu should be easiest to install. Almost all distributions have packages.
Use this for single user environment for all caches.
- Use Redis or Memcached for distributed environments.
For the local cache (you can configure two) take APCu.
'memcache.local' => '\OC\Memcache\APCu',
Memory caching backend for locally stored data
- Used for host-specific data, e.g. file paths
'memcache.distributed' => '\OC\Memcache\Memcached',
Memory caching backend for distributed data
- Used for installation-specific data, e.g. database caching
- If unset, defaults to the value of memcache.local
'redis' => array(
'host' => 'localhost', // can also be a unix domain socket: '/tmp/redis.sock'
'port' => 6379,
'timeout' => 0.0,
'password' => '', // Optional, if not defined no password will be used.
'dbindex' => 0, // Optional, if undefined SELECT will not run and will use Redis Server's default DB Index.
),
Connection details for redis to use for memory caching.
For enhanced security it is recommended to configure Redis
to require a password. See http://redis.io/topics/security
for more information.
'memcached_servers' => array(
// hostname, port and optional weight. Also see:
// http://www.php.net/manual/en/memcached.addservers.php
// http://www.php.net/manual/en/memcached.addserver.php
array('localhost', 11211),
//array('other.host.local', 11211),
),
Server details for one or more memcached servers to use for memory caching.
Location of the cache folder, defaults to data/$user/cache where
$user is the current user. When specified, the format will change to
$cache_path/$user where $cache_path is the configured cache directory
and $user is the user.
Using Object Store with ownCloud
'objectstore' => array(
'class' => 'OC\\Files\\ObjectStore\\Swift',
'arguments' => array(
// trystack will user your facebook id as the user name
'username' => 'facebook100000123456789',
// in the trystack dashboard go to user -> settings -> API Password to
// generate a password
'password' => 'Secr3tPaSSWoRdt7',
// must already exist in the objectstore, name can be different
'container' => 'owncloud',
// create the container if it does not exist. default is false
'autocreate' => true,
// required, dev-/trystack defaults to 'RegionOne'
'region' => 'RegionOne',
// The Identity / Keystone endpoint
'url' => 'http://8.21.28.222:5000/v2.0',
// required on dev-/trystack
'tenantName' => 'facebook100000123456789',
// dev-/trystack uses swift by default, the lib defaults to 'cloudFiles'
// if omitted
'serviceName' => 'swift',
// The Interface / url Type, optional
'urlType' => 'internal'
),
),
This example shows how to configure ownCloud to store all files in a
swift object storage.
It is important to note that ownCloud in object store mode will expect
exclusive access to the object store container because it only stores the
binary data for each file. The metadata is currently kept in the local
database for performance reasons.
WARNING: The current implementation is incompatible with any app that uses
direct file IO and circumvents our virtual filesystem. That includes
Encryption and Gallery. Gallery will store thumbnails directly in the
filesystem and encryption will cause severe overhead because key files need
to be fetched in addition to any requested file.
One way to test is applying for a trystack account at http://trystack.org/
Sharing
Global settings for Sharing
'sharing.managerFactory' => '\OC\Share20\ProviderFactory',
Replaces the default Share Provider Factory. This can be utilized if
own or 3rdParty Share Providers be used that – for instance – uses the
filesystem instead of the database to keep the share information.
All other configuration options
'dbdriveroptions' => array(
PDO::MYSQL_ATTR_SSL_CA => '/file/path/to/ca_cert.pem',
),
Additional driver options for the database connection, eg. to enable SSL
encryption in MySQL.
'sqlite.journal_mode' => 'DELETE',
sqlite3 journal mode can be specified using this configuration parameter -
can be ‘WAL’ or ‘DELETE’ see for more details https://www.sqlite.org/wal.html
'supportedDatabases' => array(
'sqlite',
'mysql',
'pgsql',
'oci',
),
Database types that are supported for installation.
- Available:
- sqlite (SQLite3 - Not in Enterprise Edition)
- mysql (MySQL)
- pgsql (PostgreSQL)
- oci (Oracle - Enterprise Edition Only)
'tempdirectory' => '/tmp/owncloudtemp',
Override where ownCloud stores temporary files. Useful in situations where
the system temporary directory is on a limited space ramdisk or is otherwise
restricted, or if external storages which do not support streaming are in
use.
The Web server user must have write access to this directory.
The hashing cost used by hashes generated by ownCloud
Using a higher value requires more time and CPU power to calculate the hashes
'blacklisted_files' => array('.htaccess'),
Blacklist a specific file or files and disallow the upload of files
with this name. .htaccess is blocked by default.
WARNING: USE THIS ONLY IF YOU KNOW WHAT YOU ARE DOING.
Define a default folder for shared files and folders other than root.
If you are applying a theme to ownCloud, enter the name of the theme here.
The default location for themes is owncloud/themes/.
'cipher' => 'AES-256-CFB',
The default cipher for encrypting files. Currently AES-128-CFB and
AES-256-CFB are supported.
'minimum.supported.desktop.version' => '1.7.0',
The minimum ownCloud desktop client version that will be allowed to sync with
this server instance. All connections made from earlier clients will be denied
by the server. Defaults to the minimum officially supported ownCloud version at
the time of release of this server version.
When changing this, note that older unsupported versions of the ownCloud desktop
client may not function as expected, and could lead to permanent data loss for
clients or other unexpected results.
'quota_include_external_storage' => false,
EXPERIMENTAL: option whether to include external storage in quota
calculation, defaults to false.
'filesystem_check_changes' => 0,
Specifies how often the filesystem is checked for changes made outside
ownCloud.
0 -> Never check the filesystem for outside changes, provides a performance
increase when it’s certain that no changes are made directly to the
filesystem
1 -> Check each file or folder at most once per request, recommended for
general use if outside changes might happen.
'asset-pipeline.enabled' => false,
All css and js files will be served by the Web server statically in one js
file and one css file if this is set to true. This improves performance.
'assetdirectory' => '/var/www/owncloud',
The parent of the directory where css and js assets will be stored if
pipelining is enabled; this defaults to the ownCloud directory. The assets
will be stored in a subdirectory of this directory named ‘assets’. The
server must be configured to serve that directory as $WEBROOT/assets.
You will only likely need to change this if the main ownCloud directory
is not writeable by the Web server in your configuration.
'mount_file' => '/var/www/owncloud/data/mount.json',
Where mount.json file should be stored, defaults to data/mount.json
in the ownCloud directory.
'filesystem_cache_readonly' => false,
When true, prevent ownCloud from changing the cache due to changes in the
filesystem for all storage.
Secret used by ownCloud for various purposes, e.g. to encrypt data. If you
lose this string there will be data corruption.
'trusted_proxies' => array('203.0.113.45', '198.51.100.128'),
List of trusted proxy servers
If you configure these also consider setting forwarded_for_headers which
otherwise defaults to HTTP_X_FORWARDED_FOR (the X-Forwarded-For header).
'forwarded_for_headers' => array('HTTP_X_FORWARDED', 'HTTP_FORWARDED_FOR'),
Headers that should be trusted as client IP address in combination with
trusted_proxies. If the HTTP header looks like ‘X-Forwarded-For’, then use
‘HTTP_X_FORWARDED_FOR’ here.
If set incorrectly, a client can spoof their IP address as visible to
ownCloud, bypassing access controls and making logs useless!
Defaults to ‘HTTP_X_FORWARED_FOR’ if unset
'max_filesize_animated_gifs_public_sharing' => 10,
max file size for animating gifs on public-sharing-site.
If the gif is bigger, it’ll show a static preview
Value represents the maximum filesize in megabytes. Default is 10. Set to
-1 for no limit.
'filelocking.enabled' => true,
Enables transactional file locking.
This is enabled by default.
Prevents concurrent processes from accessing the same files
at the same time. Can help prevent side effects that would
be caused by concurrent operations. Mainly relevant for
very large installations with many users working with
shared files.
'memcache.locking' => '\\OC\\Memcache\\Redis',
Memory caching backend for file locking
Because most memcache backends can clean values without warning using redis
is highly recommended to avoid data loss.
Set this ownCloud instance to debugging mode
Only enable this for local development and not in production environments
This will disable the minifier and outputs some additional debug information
'copied_sample_config' => true,
This entry is just here to show a warning in case somebody copied the sample
configuration. DO NOT ADD THIS SWITCH TO YOUR CONFIGURATION!
If you, brave person, have read until here be aware that you should not
modify ANY settings in this file without reading the documentation.
App config options
Retention for activities of the activity app:
'activity_expire_days' => 365,
Every day a cron job is ran, which deletes all activities for all users
which are older then the number of days that is set for activity_expire_days
