Centos7使用yum命令安裝Mysql5.6.X

首先：具體的安裝步驟在mysql官方文檔上都有詳細的描述。

文檔雖然是英文，不過很容易理解，我就不一一翻譯了。

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

目前mysql最新版本爲：5.7.x

但由於5.7版本比以前版本改動比較大，因此項目中通常仍是在用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.

　　由於centos版本是7.x，至於爲何是mysql57-community-release-el7-11.noarch.rpm，文檔中有以下解釋：

　　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

 ps：如何卸載 yum localinstall

# 先查看已經安裝的rpm包
rpm -qa|grep mysql
mysql-libs-5.1.73-8.el6_8.x86_64
mysql80-community-release-el7-1.noarch

# 卸載上一步獲得的兩個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

若是你只想安裝mysql client或者mysqldump等，可執行以下命令

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、安裝後的mySql配置文件位置

/etc/my.cnf
