1.前言

因为直接使用yum install默认安装的版本是5.1，查阅官网后使用Yum Repository安装mysql5.7，这里下载的版本是mysql57-community-release-el6-11.noarch.rpm。

2.安装

1）添加yum repository

[root@localhost opt]# sudo yum localinstall mysql57-community-release-el6-11.noarch.rpm

[root@localhost opt]# yum repolist enabled | grep "mysql.*-community.*"

2）安装mysql

1 [root@localhost /]# sudo yum install mysql-community-server

3）启动mysql及查看服务

1 [root@localhost /]# service mysqld start
2 Initializing MySQL database:                               [  OK  ]
3 Installing validate password plugin:                       [  OK  ]
4 Starting mysqld:                                           [  OK  ]
5 [root@localhost /]# sudo service mysqld status
6 mysqld (pid  42363) is running...

4）修改密码

因mysql有默认密码，先生成临时密码，登录mysql后再修改密码。

1 [root@localhost /]# sudo grep 'temporary password' /var/log/mysqld.log
2 2017-06-27T15:19:54.431342Z 1 [Note] A temporary password is generated for root@localhost: InA1Mppj%R1K

登录mysql

1 [root@localhost /]# mysql -uroot -p
2 Enter password:

设置密码，mysql密码要求大、小写、数字、特殊字符各一个且长度不能低于八位。
