centos6.9 installation mariadb failure and solution

Yum Install Mariadb-server mariadb-client

Tip: Mysql-server-5.1.73-8.el6_8.x86_64 was supposed to being removed is not!

Since the installation of the operating system, MySQL also installed a piece, but the installation of MARIADB does not uninstall the previous installation of MySQL, resulting in mariadb installation failure.

1, first find out the installed MySQL package

[Email protected] ~]# Rpm-qa | Grep-i ' ^mysql-'
Mysql-server-5.1.73-8.el6_8.x86_64

2. If MySQL is on, turn it off first

[[email protected] ~]#/etc/init.d/mysqld stop
Stopping mysqld: [OK]

3. Uninstall and install the MySQL package

[Email protected] ~]# rpm--nodeps-ev mysql-server-5.1.73-8.el6_8.x86_64

4. Check if MySQL is uninstalled

[Email protected] ~]# Rpm-qa | Grep-i ' ^mysql-'

There are no MySQL-related packages that are not displayed, and have been uninstalled.

5. Re-execute MARIADB installation

Yum Install Mariadb-server mariadb-client

6. View the files generated by the installation mariadb

[Email protected] ~]# RPM-QL mariadb-server

/etc/init.d/mysql
/etc/logrotate.d/mysql
/etc/my.cnf.d
/etc/my.cnf.d/server.cnf
....

7. Start the service

[[email protected] ~]#/etc/init.d/mysql start
Starting mysql.180120 16:22:20 mysqld_safe Logging to '/var/lib/mysql/centos6_103.sunan.err '.
