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
