Centos7下mariadb忘记root密码处理

1，停止mariadb服务

??????????systemctl stop mariadb

??????? 2，修改配置文件 vim /etc/my.cnf
??????????? 在[mysqld]下添加skip-grant-tables
??????????? 意思是忽略密码，?保存并退出

??????? 3，启动Mariadb
?????????systemctl start mariadb

??? ???? 4，修改密码
??????????? mysql
use mysql;
UPDATE user SET Password = password ( ‘new-password‘ ) WHERE User = ‘root‘ ;
????????????flush privileges ;
??????????? quit

??????? 5，改回配置，重启服务
vim /etc/my.cnf 删除skip-grant-tables
???????????systemctl restart mariadb

            6 ，进入数据库
              mysql -uroot -p
                输入新密码new-password即可
