Centos7使用yum命令安装Mysql5.6.X

首先：具体的安装步骤在mysql官方文档上都有详细的描述。

文档虽然是英文，不过很容易理解，我就不一一翻译了。

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

目前mysql最新版本为：5.7.x

但由于5.7版本比以前版本改动比较大，因此项目中通常仍是在用5.6版本。

一、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.

　　由于centos版本是7.x，至于为何是mysql57-community-release-el7-11.noarch.rpm，文档中有以下解释：

　　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

 ps：如何卸载 yum localinstall

# 先查看已经安装的rpm包
rpm -qa|grep mysql
mysql-libs-5.1.73-8.el6_8.x86_64
mysql80-community-release-el7-1.noarch

# 卸载上一步获得的两个rpm包
yum remove mysql-libs-5.1.73-8.el6_8.x86_64
yum remove mysql80-community-release-el7-1.noarch

 

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 Server
baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/
enabled=1
gpgcheck=1
gpgkey=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

 

二、Install MySQL by the following command:

yum install mysql-community-server

若是你只想安装mysql client或者mysqldump等，可执行以下命令

yum install mysql-community-client

 

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

 三、安装后的mySql配置文件位置

/etc/my.cnf
