首先：具體的安裝步驟在mysql官方文檔上都有詳細的描述。

這裡造輪子是讓自己加深理解。

官方文檔地址：https://dev.mysql.com/doc/refman/5.6/en/linux-installation-yum-repo.html

目前mysql最新版本為：5.7.x

因為5.7版本比之前版本改動比較大，項目中一般還是在用5.6版本。

1、Adding the MySQL Yum Repository

　　Go to the Download MySQL Yum Repository page (http://dev.mysql.com/downloads/repo/yum/) in the MySQL Developer Zone.

　　因為centos版本是7.x，至於為什麼是mysql57-community-release-el7-11.noarch.rpm，文檔中有如下解釋：

　　The repository packages available below will provide MySQL Server 5.7 by default. Other versions can be obtained by editing the repo setup file installed by the package. 

 

yum localinstall mysql57-community-release-el7-11.noarch.rpm

 

You can check that the MySQL Yum repository has been successfully added by the following command:

yum repolist enabled | grep "mysql.*-community.*"

 

Selecting a Release Series

vim /etc/yum.repos.d/mysql-community.repo

# Specify enabled=0 to disable a subrepository,or enabled=1 to enable a subrepository.# Enable to use MySQL 5.6[mysql56-community]name=MySQL 5.6 Community Serverbaseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/enabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

You should only enable subrepository for one release series at any time. When subrepositories for more than one release series are enabled, the latest series will be used by Yum.

 

Verify that the correct subrepositories have been enabled and disabled by running the following command and checking its output:

yum repolist enabled | grep mysql

 

2、Install MySQL by the following command:

yum install mysql-community-server

 

Start the MySQL server with the following command:

systemctl start mysqld.service

 

Check the status of the MySQL server with the following command:

systemctl status mysqld.service
