<section id="introduction">
<h2>Introduction<a class="headerlink" href="#introduction" title="Link to this heading"></a></h2>
<p>Nextcloud uses <code class="docutils literal notranslate"><span class="pre">config/config.php</span></code> as its main configuration file. This file controls
various fundamental aspects of server operations. It is typically modified as part of initial
deployment, when troubleshooting, and when making adjustments to surrounding infrastructure.</p>
<p>This is a required file for all Nextcloud deployments and thus it is critical for Nextcloud
administrators to be familiar with managing it.</p>
<p>This section of the <em>Administration Manual</em> documents how to adjust this essential file,
certain special characteristics of the <code class="docutils literal notranslate"><span class="pre">config/</span></code> directory, and all of the supported
parameters that can be specified in a <code class="docutils literal notranslate"><span class="pre">config/config.php</span></code> file.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>While <code class="docutils literal notranslate"><span class="pre">config/config.php</span></code> is a required file, many Nextcloud or Nextcloud app
settings are managed elsewhere and thus not included in it. These settings are typically
managed via individual apps.</p>
</div>
</section>
<section id="loading">
<h2>Loading<a class="headerlink" href="#loading" title="Link to this heading"></a></h2>
<p>Configuration files located in <code class="docutils literal notranslate"><span class="pre">config/</span></code> are parsed automatically when Nextcloud
starts up. They are also checked for changes periodically (approximately every two seconds
in a standard PHP environment running with default <em>OPcache</em> settings; approximately every
sixty seconds in many pre-packaged Nextcloud installation methods).</p>
<p>The <code class="docutils literal notranslate"><span class="pre">config/config.php</span></code> file may be supplemented by additional <code class="docutils literal notranslate"><span class="pre">*.config.php</span></code> files
placed in the <code class="docutils literal notranslate"><span class="pre">config/</span></code> directory (if appropriately named and formatted).</p>
<div class="admonition danger">
<p class="admonition-title">Danger</p>
<p>Be cautious when naming or creating backup copies of your active
<code class="docutils literal notranslate"><span class="pre">config/config.php</span></code>. If a backup is located within <code class="docutils literal notranslate"><span class="pre">config/</span></code> and is named
<code class="docutils literal notranslate"><span class="pre">(ANYTHING).config.php</span></code>, it will be loaded as part of your live configuration
and override your <code class="docutils literal notranslate"><span class="pre">config/config.php</span></code> values!</p>
</div>
<div class="admonition tip">
<p class="admonition-title">Tip</p>
<p>If your configuration changes don’t seem to be taking effect, check: (a) your PHP opcache
configuration; (b) for additional <code class="docutils literal notranslate"><span class="pre">*.config.php</span></code> files located in <code class="docutils literal notranslate"><span class="pre">config/</span></code>; (c) the documentation
for your Nextcloud installation method/package; (d) the output of <code class="docutils literal notranslate"><span class="pre">occ</span> <span class="pre">config:list</span> <span class="pre">system</span></code>.</p>

<section id="format">
<h2>Format<a class="headerlink" href="#format" title="Link to this heading"></a></h2>
<p>The short answer is that <code class="docutils literal notranslate"><span class="pre">config/</span></code> files are plain text files with some special formatting
requirements for different types of parameters and values. This makes it extensible and easy for
Nextcloud to interact with. It also makes it easy for administartors to view with any text viewer
and from the command-line.</p>
<p>Technically these configuration files are PHP files containing a special (to Nextcloud) PHP array
called <code class="docutils literal notranslate"><span class="pre">$CONFIG</span></code>. This array consists of various Nextcloud specific “key-value” pairs (in some cases
arrays themselves). Each pair has the form <code class="docutils literal notranslate"><span class="pre">key</span> <span class="pre">=&gt;</span> <span class="pre">value</span></code> and is comma-separated.</p>

<section id="multiple-merged-configuration-files">
<h2>Multiple/Merged Configuration Files<a class="headerlink" href="#multiple-merged-configuration-files" title="Link to this heading"></a></h2>
<p>Nextcloud supports loading configuration parameters from multiple files. You can add arbitrary
files ending with <code class="docutils literal notranslate"><span class="pre">.config.php*</span></code> (i.e. <code class="docutils literal notranslate"><span class="pre">*.config.php</span></code>) in the <code class="docutils literal notranslate"><span class="pre">config/</span></code> directory. The values
in these files take precedence over <code class="docutils literal notranslate"><span class="pre">config/config.php</span></code>. 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 Nextcloud.</p>
<p>For example, you could place your email server configuration in <code class="docutils literal notranslate"><span class="pre">config/email.config.php</span></code> and
whatever parameters you specify in it will be merged with your <code class="docutils literal notranslate"><span class="pre">config/config.php</span></code>.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>The values in these additional configuration files <strong>always</strong> take precedence over

</div>
<p>To have clean URLs without <cite>/index.php</cite> this parameter needs to be configured.</p>
<p>This parameter will be written as “RewriteBase” on update and installation of
Nextcloud to your <cite>.htaccess</cite> file. While this value is often simply the URL
path of the Nextcloud installation it cannot be set automatically properly in
every scenario and needs thus some manual configuration.</p>
<p>In a standard Apache setup this usually equals the folder that Nextcloud is
accessible at. So if Nextcloud is accessible via “<a class="reference external" href="https://mycloud.org/nextcloud">https://mycloud.org/nextcloud</a>”
the correct value would most likely be “/nextcloud”. If Nextcloud is running
under “<a class="reference external" href="https://mycloud.org/">https://mycloud.org/</a>” then it would be “/”.</p>
<p>Note that the above rule is not valid in every case, as there are some rare setup
cases where this may not apply. However, to avoid any update problems this
configuration value is explicitly opt-in.</p>
<p>After setting this value run <cite>occ maintenance:update:htaccess</cite>. Now, when the
following conditions are met Nextcloud URLs won’t contain <cite>index.php</cite>:</p>
<ul class="simple">
<li><p><cite>mod_rewrite</cite> is installed</p></li>
<li><p><cite>mod_env</cite> is installed</p></li>

<p>For server setups, that don’t have <cite>mod_env</cite> enabled or restricted (e.g. suEXEC)

<p>Please check, if <cite>mod_rewrite</cite> is active and functional before setting this
parameter, and you updated your .htaccess with <cite>occ maintenance:update:htaccess</cite>.
Otherwise, your nextcloud installation might not be reachable anymore.

<p>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.</p>
<p>If the user quota limit is exceeded due to deleted files in the trash bin,
retention settings will be ignored and files will be cleaned up until
the quota requirements are met.</p>
<p>The app allows for two settings, a minimum time for trash bin retention,
and a maximum time for trash bin retention.</p>
<p>Minimum time is the number of days a file will be kept, after which it
<em>may be</em> deleted. A file may be deleted after the minimum number of days
is expired if space is needed. The file will not be deleted if space is
not needed.</p>
<p>Whether “space is needed” depends on whether a user quota is defined or not:</p>
<blockquote>
<div><ul class="simple">
<li><p>If no user quota is defined, the available space on the Nextcloud data
partition sets the limit for the trashbin

<li><p>If a user quota is defined, 50% of the user’s remaining quota space sets
the limit for the trashbin.</p></li>
</ul>
</div></blockquote>
<p>Maximum time is the number of days at which it is <em>guaranteed
to be</em> deleted. There is no further dependency on the available space.</p>
<p>Both minimum and maximum times can be set together to explicitly define
file and folder deletion. For migration purposes, this setting is installed

<p>If it is not, then any options controlled by <code class="docutils literal notranslate"><span class="pre">.htaccess</span></code>, such as large

<p>Advice on choosing between the various backends:</p>
<ul class="simple">
<li><p>APCu should be easiest to install. Almost all distributions have packages.
Use this for single user environment for all caches.</p></li>
<li><p>Use Redis or Memcached for distributed environments.
For the local cache (you can configure two) take APCu.</p></li>

<p>Connection details for redis to use for memory caching in a single server configuration.</p>
<p>For enhanced security it is recommended to configure Redis
to require a password. See <a class="reference external" href="http://redis.io/topics/security">http://redis.io/topics/security</a>
for more information.</p>
<p>We also support redis SSL/TLS encryption as of version 6.

<p>Connection details for a Redis Cluster.</p>
<p>Redis Cluster support requires the php module phpredis in version 3.0.0 or
higher.</p>
<dl class="simple">
<dt>Available failover modes:</dt><dd><ul class="simple">
<li><p>\RedisCluster::FAILOVER_NONE - only send commands to master nodes (default)</p></li>
<li><p>\RedisCluster::FAILOVER_ERROR - failover to slaves for read commands if master is unavailable (recommended)</p></li>
<li><p>\RedisCluster::FAILOVER_DISTRIBUTE - randomly distribute read commands across master and slaves</p></li>
</ul>
</dd>
</dl>
<p>WARNING: FAILOVER_DISTRIBUTE is a not recommended setting, and we strongly
suggest to not use it if you use Redis for file locking. Due to the way Redis
is synchronized it could happen, that the read for an existing lock is
scheduled to a slave that is not fully synchronized with the connected master
which then causes a FileLocked exception.</p>
<p>See <a class="reference external" href="https://redis.io/topics/cluster-spec">https://redis.io/topics/cluster-spec</a> for details about the Redis cluster</p>
<p>Authentication works with phpredis version 4.2.1+. See

<p>This example shows how to configure Nextcloud to store all files in a
swift object storage.</p>
<p>It is important to note that Nextcloud 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.</p>
<p>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.</p>

<p>Additional driver options for the database connection, e.g. to enable SSL
encryption in MySQL or specify a custom wait timeout on a cheap hoster.</p>
<p>When setting up TLS/SSL for encrypting the connections, you need to ensure that
the passed keys and certificates are readable by the PHP process. In addition,
PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT might need to be set to false, if the
database servers certificates CN does not match with the hostname used to connect.
The standard behavior here is different from the MySQL/MariaDB CLI client, which
does not verify the server cert except –ssl-verify-server-cert is passed manually.</p>

<p>For search queries in the database, a default collation – depending on the
character set – is chosen. In some cases a different behaviour is desired,
for instances when an accent sensitive search is desired.</p>
<p>MariaDB and MySQL have an overlap in available collations, but also
incompatible ones, also depending on the version of the database server.</p>
<p>This option allows to override the automatic choice. Example:</p>
<p>‘mysql.collation’ =&gt; ‘utf8mb4_0900_as_ci’,</p>
<p>This setting has no effect on setup or creating tables. In those cases
always utf8[mb4]_bin is being used. This setting is only taken into
consideration in SQL queries that utilize LIKE comparison operators.</p>

to the user that states “Your email address on URL was changed by an
administrator.”. In some cases this should not be triggered, because it was a

<code class="docutils literal notranslate"><span class="pre">disable_email.email_address_changed_by_admin</span></code> can be set to <code class="docutils literal notranslate"><span class="pre">yes</span></code>:</p>
