Question

How can I install OnApp Control Panel with MariaDB as database server?

Answer

To install the OnApp Control Panel with MariaDB as database server:

1. Go to the /onapp/onapp-cp.conf
2. Set the WITH_MARIADB=1 parameter
   
3. Proceed with OnApp Control Panel install or upgrade .

To upgrade from OnApp with MySQL to OnApp with MariaDB, Percona Servers or Percona Cluster, please see Migrate existing OnApp database from MySQL to MariaDB, Percona Servers or Percona Cluster . 

You cannot upgrade your Control Panel switching to MariaDB in your /onapp/onapp-cp.conf file if you have MySQL installed and vice versa.

• In case you have MySQL installed and in the configuration file you set 'WITH_MARIADB=1', the installer will exit with the warning.

• Backward migration from MariaDB to MySQL is not possible, so, in case  MariaDB was previously used and you set 'WITH_MARIADB=0' during the upgrade process, the installer will exit with the warning message.
