无法在centos 6.9上启动mysql服务器 [英] Can't start mysql server on centos 6.9

问题描述

我的操作系统是centos 6.9。

My OS is centos 6.9.

我将MySQL版本从5.1更新到5.5，然后它开始工作了。
但是在重新启动sshd之后，我无法启动MySQL服务器。

I updated the MySQL version from 5.1 to 5.5 and then it worked. But after sshd restarted, I can't start the MySQL server.

我尝试过：

# service mysql start

错误消息：

Starting MySQL.Logging to '/var/lib/mysql/host.err'.
200425 12:44:09 mysqld_safe Directory '/var/lib/mysql' for UNIX socket file don't exists.
ERROR! The server quit without updating PID file (/var/lib/mysql/host.pid).

/ var / lib / mysql目录不存在，我不确定为什么不存在存在。

/var/lib/mysql directory doesn't exist and I am not sure why it doesn't exist.

我读过很多论坛帖子，但我还没有解决。

I've read many forum posts but I didn't solve this yet.

如何我可以解决这个问题吗？

How can I solve this?

任何帮助都是值得的。

推荐答案

如果/ var / lib / mysql不存在，这非常令人担忧。是否在未挂载的其他文件系统上？如果幸运的话，只会丢失挂载点，而不会挂载文件系统。如果不是这种情况，我只能希望您有一个备份。 ：-（

If /var/lib/mysql doesn't exist, that is extremely concerning. Is it on a different file system that is not mounted? If you are lucky, only the mount point is missing and the file system isn't mounted. If that is not the case, I can only hope you have a backup. :-(
