从 MySQL 官网选取合适的 MySQL 版本，获取下载地址。
然后使用 wget 下载：
[root@localhost ~]# wget http://dev.mysql.com/get/mysql57-community-release -el7-7.noarch.rpm --2017-10-19 04:44:56-- http://dev.mysql.com/get/mysql57-community-release -el7-7.noarch.rpm Resolving dev.mysql.com (dev.mysql.com)... 137.254.60.11

安装

等待执行安装完成。
然后启动，注意 CentOS7 的启动方式和以前不一样，CentOS7 使用了 systemctl
[root@localhost ~]# systemctl start mysqld.service
查看启动是否成功
[root@localhost ~]# systemctl status mysqld.service
● mysqld.service - MySQL Server
Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor
preset: disabled)

Hint: Some lines were ellipsized, use -l to show in full.
上面显示 active (running) 则表示已经正常启动。
然后就可以进入数据库了，这里注意一点，MySQL5.7.6 之后会在启动 mysql 进程的时候生成一个用户密码，首次登陆需要这个密码才行。密码保存在 mysql 进程的日志里，即(/var/log/mysqld.log)
查看登陆密码
[root@localhost ~]# cat /var/log/mysqld.log | grep ‘password‘ 2017-10-18T20:54:59.169015Z 1 [Note] A temporary password is generated for root@localhost: I-<k&>wb&0h*
然后登陆
[root@localhost ~]# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.7.20 Copyright (c) 2000, 2017, Oracle and/or its affiliates. All rights reserved . Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input stateme nt. mysql>
到这里 MySQL 就完全安装完成了。
但是如果想正常使用还需要修改密码，以前的 password()函数将会被抛弃，官方建议使用下面的命令来修改密码
mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘new_password‘; ERROR 1819 (HY000): Your password does not satisfy the current policy requi rements
密码不能太简单
这里我们注意设置密码 长度要大于8，同时要有数字，大小写，特殊字符。
最后，安装完了可以删除 MySQL 的 Repository ，这样可以减少 yum 检查更新的时间，使用下面的命令。
[root@localhost ~]# yum -y remove mysql57-community-release-el7-8.noarch
