mysql - 无法通过套接字 'var run mysqld mysqld.sock 在 Ubuntu 上连接到 mysql 服务器 (Emma)

Question

我收到此错误

cannot connect to mysql server through socket 'var/run/mysqld/mysqld.sock'(2)

当我单击 mysql(Emma) localhost 并收到此错误时，我 googling它但没有用，并且还给出了下面的命令，我尝试过但只收到错误。

 $ps ax | grep mysql
   4348 pts/5    S+     0:00 grep --color=auto mysql
 $sudo service mysql start
   Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
 $sudo /etc/init.d/mysql start
   [....] Starting mysql (via systemctl): mysql.serviceJob for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details. failed!

我该怎么办，有人可以给我建议吗
