安装mysql5.7
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm #下载源
rpm -ivh mysql57-community-release-el7-10.noarch.rpm #安装yum源
yum -y install mysql-community-server #yum 安装mysql5.7
配置文件在/etc/my.cnf ，支持systemctl 管理

修改完配置文件后，启动mysql
mysql5.7的root密码是随机生成写在日志里的，密码需要包含复杂性
systemctl start mysqld #启动
grep "pass" /var/log/mysql_error.log #查看root密码，最后一串
mysql -u root -p #输入密码，登录mysql
mysql> alter user 'root'@'localhost' identified by 'MysqlPassword1!'; #在mysql命令行，修改root密码为MysqlPassword1!，密码需要符合复杂性要求
mysql> flush privileges; #刷新权限
mysql> \q ; #退出mysql终端
mysql -u root -p #使用新密码登录mysql
mysql> grant all on *.* to 'root'@'%' identified by 'MysqlPassword2!'; #命令行修改远程root用户密码为MysqlPassword2!
mysql> flush privileges; #刷新权限
mysql> \q ; #退出mysql终端
