Step 1 Remove MariaDB 5.5/10.0/10.1/10.2

Before installing it is recommended to backup your databases, although it is not necessary if you followed this steps carefully.

First backup your current my.cnf config :

Code: Select all

cp /etc/my.cnf /etc/my.cnf.bak

Now we need to remove current version of mariadb 5.5 installed on centos 7 :

For MariaDB 5.5 :

Code: Select all

service mariadb stop  /  service mysql stop
yum remove mariadb mariadb-server

At this point MariaDB 5.5 will be removed completely but the databases are not removed don’t need to worry.

For MariaDB 10.0/10.1/10.2 :

Code: Select all

service mysql stop 
yum remove MariaDB-server MariaDB-client

At this point MariaDB 10.0/10.1/10.2 will be removed completely but the databases are not removed don’t need to worry.

Then Install MariaDB 10.3 :

Step 2 Installation/Updating from MariaDB 5.5/10.0/10.1/10.2 to MariaDB 10.3

Install/enable Official repo for mariadb 10.3:

Code: Select all

yum install nano epel-release -y

Now edit/create the Repo file :

Ensure you don’t have any other MariaDB repo file in /etc/yum.repos.d if exists delete or backup the existing repo file :

Code: Select all

mv /etc/yum.repos.d/mariadb.repo /etc/yum.repos.d/mariadb.repo.bak
nano /etc/yum.repos.d/mariadb.repo

then paste this lines and save it :

Code: Select all

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

After that we’ll install Mariadb 10.3

Code: Select all

yum clean all
yum install MariaDB-server MariaDB-client net-snmp perl-DBD-MySQL -y
yum update -y

Restore the my.cnf file :

Code: Select all

rm -rf /etc/my.cnf
cp /etc/my.cnf.bak /etc/my.cnf

Then enable mariadb to start on boot and start the service :

Code: Select all

systemctl enable mysql
service mysql start

Final Step

After that we need to upgrade current databases by this command :

Code: Select all

mysql_upgrade

that’s it you’ve successfully upgraded MariaDB 5.5/10.0/10.1/10.2 to MariaDB 10.3.

You can confirm the version by running this command from terminal ssh:

Code: Select all

mysql

I get "Failed to execute operation: Too many levels of symbolic links" on a fresh install on centos 7 when running the "systemctl enable mysql" command.

Is there any ways around this?

Code: Select all

systemctl enable mariadb

Code: Select all

systemctl start mariadb

Missing two steps for pid file:

1. Create file if not exist /usr/lib/tmpfiles.d/mariadb.conf as root user with following content.

Code: Select all

d /var/run/mariadb 0755 mysql mysql -

2. Add pid-file location in /etc/my.cnf like bellow

Code: Select all

[mysqld]
pid-file=/var/run/mariadb/mariadb.pid
datadir=/var/lib/mysql

3. Reboot server and check mariadb.pid exist in /var/run/mariadb then Done.
