Migrate Plesk to MariaDB 10.1

AMP Version

Migrating Plesk to MariaDB 10.1 is fairly simple, currently Plesk officially supports up to MariaDB 10 and MySQL 5.6 (since writing 10.1 is now supported), so this is “use at your own risk”. I’ve run Plesk with MariaDB 10.1 on various operating systems, here I’ll show you how to install on Ubuntu 14 LTS from the MariaDB repository…

Please Note: An in place upgrade like this does not work on Ubuntu 16, you need to install MariaDB prior to installing Plesk, though I will be coming back to this issue when I have time.

Preparation

1. Import the key

apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db

2. Add the repository

add-apt-repository 'deb [arch=amd64,i386] http://lon1.mirrors.digitalocean.com/mariadb/repo/10.1/ubuntu trusty main'

3. Now update apt…

apt-get update

4. Stop the current MySQL/MariaDB process (if you use WatchDog to monitor MySQL/MariaDB stop monitoring first)

/opt/psa/admin/bin/modules/watchdog/wd --unmonit-service=mysql​

And

service mysql stop

Installation

5. Install like so…

env DEBIAN_FRONTEND=noninteractive apt-get -o OrderList::Score::Immediate=1000 \
    install libjemalloc1 galera-3 libmysqlclient18 libmariadbclient18 mariadb-common mariadb-client-core-10.1 mariadb-client-10.1 mariadb-server mariadb-server-core-10.1 mariadb-server-10.1

If prompted to set a password, leave blank to keep your current, and you should over write the my.cnf file with the latest version to make sure you get all the optimizations added for MariaDB, especially if you are coming from MySQL.

Final Stage

6. Now you can start the MySQL service and start Watchdog monitoring…
Stop the current MySQL/MariaDB process (if you use WatchDog to monitor MySQL/MariaDB stop monitoring first)

/opt/psa/admin/bin/modules/watchdog/wd --monit-service=mysql​

And

service mysql start

Should you have any problems, please see the notes at the bottom of my post on Migrating Plesk to MariaDB

Migrate Plesk to MariaDB

AMP Version

The guide at Plesk’s DevBlog results in dependency issues on Ubuntu 14.
Here’s what the command should be when migrating to MariaDB on Ubuntu 14.04.2 LTS with Plesk 12.0.18.

1. Log in as root and run…

# apt-get update

2. And run the following updated command…

# env DEBIAN_FRONTEND=noninteractive apt-get -o OrderList::Score::Immediate=1000 \
install libmariadbclient18 mariadb-client-5.5 mariadb-client-core-5.5 mariadb-common mariadb-server mariadb-server-5.5 mariadb-server-core-5.5

3. Check you have MariaDB installed with

# mysql -V
mysql  Ver 15.1 Distrib 5.5.41-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

I hope that helps someone else.
