Ansible Role librenms

This role installs and configures LibreNMS.

Mandatory Requirements

Install Python 3, and the python3-policycoreutils module (required for the SELinux Ansible tasks). This can be done using the linuxfabrik.lfops.policycoreutils role.
Install MariaDB, and create a database and a user for said database. This can be done using the linuxfabrik.lfops.mariadb-server role.
Install a web server (for example Apache httpd), and configure a virtual host for LibreNMS. This can be done using the linuxfabrik.lfops.apache_httpd role.
Install PHP version >= 7.3. This can be done using the linuxfabrik.lfops.php role.
On RHEL-compatible systems, enable the httpd_can_connect_ldap and httpd_setrlimit SELinux booleans. This can be done using the linuxfabrik.lfops.selinux role.
On RHEL-compatible systems, set the appropriate SELinux file contexts (have a look at librenms__selinux__fcontexts__dependent_var in the defaults/main.yml). This can be done using the linuxfabrik.lfops.selinux role.

If you use the „Setup LibreNMS“ Playbook, this is automatically done for you.
