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
