Install skip mariadb installation #63

Centmin Mod is for fresh OS installs only so if you have existing web stack elements like apache, php or percona mysql then i recommend you do not install Centmin Mod as there's no tests for compatibility in the routines to work nicely with other existing web stack software. So not doable right now.

 

To elaborate further, centmin mod doesn't just install the LEMP stack software, it auto tunes each nginx, php-fpm and mariadb mysql and csf firewall based on detected server's resources including cpu, memory and disk i/o performance and OS capabilities - CentOS 6 vs 7, 32bit vs 64bit, linux kernel detected etc. So it's highly optimised and expects certain software like MariaDB 10.0 or 10.1 versions.

You can probably install Centmin Mod first, then manually remove MariaDB and replace with Percona Cluster/MySQL afterwards though.

But it's partially about what I am willing to support technically with my free time and the known LEMP stack software makes it easier even though I do also play with Percona MySQL as well. But for for efficiency, focusing on just MariaDB 10.0/10.1/10.2 is best use of my free time.

FYI, if you use Centmin Mod 123.09beta01 it uses MariaDB 10.1 branch which has native Galera cluster integrated as well.

• http://tunnelix.com/mariadb-galera-cluster-installation/ step 4 not required & firewalld isn't aren't relevant but you need to whitelist ports (3306 tcp, 4567 tcp, 4568 tcp, 4444 tcp) in CSF Firewall in /etc/csf/csf.conf in TCP_IN/TCP_OUT and TCP6_IN/TCP6_OUT and 4567 udp for UDP_IN/UDP_OUT and UDP6_IN/UDP6_OUT comma separated list of whitelisted ports and restart csf firewall afterwards
  Code (Text):

  csf -r

Setup and configuration and troubleshooting for MariaDB 10.1 Galera Cluster is left to the end user though.
