<title>Matomo</title>
<para>
Matomo is a real-time web analytics application. This module configures
php-fpm as backend for Matomo, optionally configuring an nginx vhost as well.
</para>
<para>
An automatic setup is not suported by Matomo, so you need to configure Matomo
itself in the browser-based Matomo setup.
</para>
<section xml:id="module-services-matomo-database-setup">
<title>Database Setup</title>
<para>
You also need to configure a MariaDB or MySQL database and -user for Matomo
yourself, and enter those credentials in your browser. You can use
passwordless database authentication via the UNIX_SOCKET authentication
plugin with the following SQL commands:
<programlisting>
# For MariaDB
INSTALL PLUGIN unix_socket SONAME 'auth_socket';
CREATE DATABASE matomo;
CREATE USER 'matomo'@'localhost' IDENTIFIED WITH unix_socket;
GRANT ALL PRIVILEGES ON matomo.* TO 'matomo'@'localhost';
# For MySQL
INSTALL PLUGIN auth_socket SONAME 'auth_socket.so';
CREATE DATABASE matomo;
CREATE USER 'matomo'@'localhost' IDENTIFIED WITH auth_socket;
GRANT ALL PRIVILEGES ON matomo.* TO 'matomo'@'localhost';
</programlisting>
Then fill in <literal>matomo</literal> as database user and database name,
and leave the password field blank. This authentication works by allowing
only the <literal>matomo</literal> unix user to authenticate as the
<literal>matomo</literal> database user (without needing a password), but no
other users. For more information on passwordless login, see
<link xlink:href="https://mariadb.com/kb/en/mariadb/unix_socket-authentication-plugin/" />.
</para>
<para>
Of course, you can use password based authentication as well, e.g. when the
database is not on the same host.

<section xml:id="module-services-matomo-archive-processing">
<title>Archive Processing</title>
<para>
This module comes with the systemd service
<literal>matomo-archive-processing.service</literal> and a timer that
automatically triggers archive processing every hour. This means that you
can safely
<link xlink:href="https://matomo.org/docs/setup-auto-archiving/#disable-browser-triggers-for-matomo-archiving-and-limit-matomo-reports-to-updating-every-hour">
disable browser triggers for Matomo archiving </link> at
<literal>Administration > System > General Settings</literal>.
</para>
<para>
With automatic archive processing, you can now also enable to
<link xlink:href="https://matomo.org/docs/privacy/#step-2-delete-old-visitors-logs">
delete old visitor logs </link> at <literal>Administration > System >
Privacy</literal>, but make sure that you run <literal>systemctl start
matomo-archive-processing.service</literal> at least once without errors if
you have already collected data before, so that the reports get archived
before the source data gets deleted.
</para>
</section>
<section xml:id="module-services-matomo-backups">
<title>Backup</title>
<para>
You only need to take backups of your MySQL database and the
<filename>/var/lib/matomo/config/config.ini.php</filename> file. Use a user
in the <literal>matomo</literal> group or root to access the file. For more
information, see
<link xlink:href="https://matomo.org/faq/how-to-install/faq_138/" />.

<para>
Matomo's file integrity check will warn you. This is due to the patches
necessary for NixOS, you can safely ignore this.
</para>
</listitem>
<listitem>
<para>
Matomo will warn you that the JavaScript tracker is not writable. This is
because it's located in the read-only nix store. You can safely ignore
this, unless you need a plugin that needs JavaScript tracker access.

<section xml:id="module-services-matomo-other-web-servers">
<title>Using other Web Servers than nginx</title>
<para>
You can use other web servers by forwarding calls for
<filename>index.php</filename> and <filename>piwik.php</filename> to the
<literal>/run/phpfpm-matomo.sock</literal> fastcgi unix socket. You can use
the nginx configuration in the module code as a reference to what else
should be configured.
