mysql5.7以后的争强了安全机制, 所以使用yum安装,启动会系统会自动生成一个随机的密码,修改mysql密码
查看mysql的随机密码

grep 'temporary password' /var/log/mysqld.log

使用查询得到的随机密码在终端登录

mysql -u root -p    更改密码(mysql文档规定,密码必须包括大小写字母数字加特殊符号>8位)
ALTER USER 'root'@'localhost' IDENTIFIED BY 'Yourpassword';
退出mysql客户端,用刚才修改的密码登录确保密码修改成功
exit;
mysql -u root -p
