当我这样做时： mysql -u root -p 和类型 my password 这就是我得到的：
错误2002（hy000）：无法通过套接字'/var/run/mysqld/mysqld.sock'（2）连接到本地mysql服务器
所以我打这个： systemctl restart mysql 我得到了以下错误：
mysql.service的作业失败，因为控制进程退出，错误代码为。有关详细信息，请参阅“systemctl status mysql.service”和“journalctl-xe”。
所以我做了 journalctl -xe 得到这个结果：

дек 14 22:57:29 kazak systemd[1]: Failed to start MySQL Community Server.

The result is RESULT.
