1、修改 /etc/my.cnf,在 [mysqld] 小节下添加一行:skip-grant-tables=1
这一行配置让 mysqld 启动时不对密码进行验证
2、重启 mysqld 服务:systemctl restart mysqld
3、使用 root 用户登录到 mysql:mysql -u root
4、切换到mysql数据库,更新 user 表:
update user set authentication_string = password('wzw011992'), password_expired = 'N', password_last_changed = now() where user = 'wluser';
在之前的版本中,密码字段的字段名是 password,5.7版本改为了 authentication_string
5、退出 mysql,编辑 /etc/my.cnf 文件,删除 skip-grant-tables=1 的内容
6、重启 mysqld 服务,再用新密码登录即可
grant all privileges on *.* to '%'@'%' identified by 'qwe123' with grant option
flush privileges;
service mysqld restart
use awesome;
grant select,insert,update,delete on awesome.* to 'john(user)'@'localhost' identified by 'qwe123(password)';
flush privileges;
vim /etc/mysql/my.cnf
