所以今晚看似无处不在,我的wordpress网站瘫痪了,我已将其追溯到mysql的问题. Mysql不会在服务器上启动,因为它会一直失败.
这是我从日志中得到的：
140226 08:54:11 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

我已经尝试过Googling并在这里查看Stack Overflow,但我似乎找不到很多解决方案,除了删除ipdata1和日志文件,正如我读过的那样,不应该使用存储的数据,因为它会弄乱我的桌子.
这是在NGINX CentOS 6服务器上.
有任何想法吗？我很感激帮助！
解决方法:
AFAIK系统错误：2 =没有这样的文件或目录.
检查目录是否存在,mysql是否有权写入该目录,以及磁盘上是否留有足够的空间.
