每当我尝试启动sqlD服务,我得到MySQL守护程序无法启动.我试图通过执行以下操作“开始”服务：

service MysqLd start

也

当我输入：MysqL

我得到：

ERROR 2002 (HY000): Can't connect to local MysqL server through socket '/VAR/lib/MysqL/MysqL.sock' (2)

我知道该目录中应该有一个MysqL.sock文件,所以我创建一个.但文件只是自动删除自己,我继续得到错误2002.

由于错误,我也无法登录PHPMyAdmin.我可以访问PHPmyadmin页面,但登录时我得到：#2002无法登录到MysqL服务器

这是我的MysqL.LOG文件：

我跑了MysqL_upgrade并得到
