yum install mysql-community-{client,common,libs}-*

rpm -ivh mysql-community-server-5.7.12-1.el7.x86_64.rpm

启动Mysql服务

先用常规的启动方法 service mysqld start

z在使用最新启动方法 systemctl start mysqld.service

查看MySQL服务器的状态

sudo service mysqld status

生成随机密码
grep 'temporary password' /var/log/mysqld.log
2016-04-30T11:25:13.632616Z 1 [Note] A temporary password is generated for root@localhost: X9.L=p4iylZD

配置随机密码
mysql -uroot -p
X9.L=p4iylZD

ALTER USER 'root'@'localhost' IDENTIFIED BY 'HanZheng.123';

5.7中存储密码的字段不再是password了,变成了authentication_string

update mysql.user set authentication_string=password('root') where user='root'';

修改root密码后如果第一次使用root用户登入mysql系统还会需要重置一次root密码

SET PASSWORD=PASSWORD('root');

重新登陆
mysql -uroot -p
HanZheng.123
