Question

我收到错误"mysqld死但pid文件存在"

我在EC2上运行了一个acache webclient.使用WordPress.我开始看到"数据库连接错误"

当我做一个sudo服务mysqld状态我看到错误"mysqld死但pid文件存在"

看起来我有足够的空间

   Filesystem      Size  Used Avail Use% Mounted on
   /dev/xvda1      7.8G  1.5G  6.3G  19% /

   tmpfs           499M     0  499M   0% /dev/shm

当我做尾巴时,我得到了
