نصب MariaDB در centos

برای نصب mariadb در centos طبق دستور العمل زیر اقدام میکنیم:
Step #1: Add the MariaDB Repository
First, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new:
yum -y update
Now find which repo you should use with the MariaDB repository generator. We’re going to add the CentOS 6 (64 bit) MariaDB 5.5 repository.
For a refresher on editing files with vim see: New User Tutorial: Overview of the Vim Text Editor
 nano /etc/yum.repos.d/MariaDB55.repo
محتویات زیر را داخل ان کپی میکنیم
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
Step #2: Remove the Existing MySQL Installation
In some cases a manual uninstall of mysql is necessary. Be sure to backup MySQL before proceeding with the following instructions!
Stop MySQL:
service mysqld stop
Remove the existing MySQL packages:
yum -y remove mysql-server mysql
Step #3: Install MariaDB
At this point, installing MariaDB is as simple as running just one command:
yum -y install mysql-server mysql
And then start MySQL, now MariaDB, again:
service mysql start
