mysql - 无法启动服务器 : Bind on TCP/IP port: Cannot assign requested address

Question

我昨天重启了我的服务器，不幸的是现在无法启动mysql。

错误日志如下:

root@site-digger:/var/log/mysql# cat error.log 
130216 16:11:32 [Note] Plugin 'FEDERATED' is disabled.
130216 16:11:32  InnoDB: Initializing buffer pool, size = 8.0M

查了一下，没有发现有程序在使用3306，请看下面

我试过 sudo mysql start。但仍然无法正常工作。 操作系统:Ubuntu 11.10

netstat -a -t 结果如下:

端口 33 06。不是 60。 Netstat 仅显示事件连接，而不显示仅在监听的空闲连接。您需要 netstat -a -t(仅显示 tcp 端口)。
