Question

我有mysql启动错误：

131223 19:03:24 [Note] Plugin 'FEDERATED' is disabled.
131223 19:03:25  InnoDB: Started; log sequence number 55 4050118616
131223 19:03:25 [ERROR] Can't start server : Bind on unix socket: No space left on device
131223 19:03:25 [ERROR] Do you already have another mysqld server running on socket: /var/run/mysqld/mysqld.sock ?
131223 19:03:25 [ERROR] Aborting

131223 19:03:25  InnoDB: Starting shutdown...
131223 19:03:30  InnoDB: Shutdown completed; log sequence number 55 4050118616
131223 19:03:30 [Note] /usr/sbin/mysqld: Shutdown complete

当我想要做的时候

sudo mkfifo /var/run/mysqld/mysqld.sock

我有

mkfifo: cannot create fifo `/var/run/mysqld/mysqld.sock': No space left on device

df -h的结果：

     df -h

所以...我有自由空间，但我没有自由空间？如何启动mysql？

Answer 1

第4行告诉你Do you already have another mysqld server running on socket: /var/run/mysqld/mysqld.sock ?

如果/var/run/mysqld/mysqld.sock已经存在，则会失败。

Answer 2

该目录的权限是什么？ / var / run / mysqld？它们应该由mysql拥有，但在某些情况下我发现它也可能不会像mysql一样运行。如果没有，请运行chown USER /var/run/mysqld，其中USER就是您。：P

希望这会有所帮助。

mysql start：无法启动服务器：在unix socket上绑定：设备上没有剩余空间
