1、配置yum源
下载mysql源安装包
shell> wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
# 安装mysql源
shell> yum localinstall mysql57-community-release-el7-8.noarch.rpm
检查mysql源是否安装成功
shell> yum repolist enabled | grep "mysql.*-community.*"
2、安装MySQL
shell> yum install mysql-community-server
3、启动MySQL服务
shell> systemctl start mysqld
mysqld查看MySQL的启动状态
shell> systemctl status mysqld #状态如下↓↓↓↓↓
mysqld.service - MySQL Server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; disabled; vendor preset: disabled) Active: active (running) since 五 2016-06-24 04:37:37 CST; 35min ago Main PID: 2888 (mysqld) CGroup: /system.slice/mysqld.service └─2888 /usr/sbin/mysqld --daemonize --pid-file=/var/run/mysqld/mysqld.pid 6月 24 04:37:36 localhost.localdomain systemd[1]: Starting MySQL Server... 6月 24 04:37:37 localhost.localdomain systemd[1]: Started MySQL Server.
4、开机启动
shell> systemctl enable mysqld
shell> systemctl daemon-reload
5、修改root本地登录密码
mysql安装完成之后，在/var/log/mysqld.log文件中给root生成了一个默认密码。通过下面的方式找到root默认密码，然后登录mysql进行修改：
shell> grep ‘temporary password‘ /var/log/mysqld.log
shell> mysql -uroot -p
Enter password: ?aeq,W;i7cnZ
mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘MyNewPass4!‘; 或者 mysql> set password for ‘root‘@‘localhost‘=password(‘MyNewPass4!‘);
注意：mysql5.7以上版本默认安装了密码安全检查插件（validate_password），
默认密码检查策略要求密码必须包含：大小写字母、数字和特殊符号，并且长度不能少于8位。
否则会提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements错误，如下图所示：
默认配置文件路径：
配置文件：/etc/my.cnf 日志文件：/var/log//var/log/mysqld.log 服务启动脚本：/usr/lib/systemd/system/mysqld.service socket文件：/var/run/mysqld/mysqld.pid
