CentOS7 installing MySQL Server

The default yum source for CentOS 7 is mariadb, not our usual MySQL.

This article will show you how to install MySQL through yum.

1. First download the Yum source rpm package

Specific address in:

http://repo.mysql.com/

You can choose the version you want.

What I have downloaded is:

wget http://repo.mysql.com/mysql57-community-release-el7.rpm

1. Installing RPM files

Install the Yum source from MySQL by command:

RPM-IVH mysql57-community-release-el7.rpm

You can see the associated repo file in/ETC/YUM.REPOS.D:

[[email protected] yum.repos.d]# ls

Centos-base.repo Centos-debuginfo.repo Centos-media.repo Centos-vault.repo Mysql-community-source.repo

Centos-cr.repo Centos-fasttrack.repo Centos-sources.repo Mysql-community.repo Openlogic.repo

[Email protected] yum.repos.d]#

1. Yum install MySQL

Install with the Yum command:

Yum Install-y mysql-server

1. Start MySQL

Start:

Systemctl Start mysqld

View:

Systemctl Status Mysqld

Set boot up:

Systemctl Enable Mysqld

View by Netstat:
