Question

我试图重启mysql。但它没有重启。这是mysql.log的内容：

131217 17:01:09  InnoDB: Starting shutdown...
131217 17:01:11  InnoDB: Shutdown completed; log sequence number 153229469

131217 17:01:11 [ERROR] Unknown/unsupported storage engine: InnoDB

任何人都可以帮我找到原因吗？实际上mysql在这段时间之前就已经工作了，似乎这不是一个常规的错误！如果有任何其他信息，请告诉我。

非常感谢

Answer 1

您是否检查过磁盘分区是否存在问题？可能是它的空间不足或有问题。该错误清楚地表明问题是由创建临时文件失败引起的。列出休息是因为InnoDB无法初始化。

Answer 2

此错误明确提到MySQL守护程序无法在/ tmp目录下创建临时文件。

请检查/ tmp目录的权限。

您的/ tmp目录权限应具有粘性。以下是相同的示例。

drwxrwxrwt   3 root root 4.0K Feb  4 13:48 tmp

Mysql没有启动
