MySQL，无法创建UNIX套接字(12) [英] MySQL, Can't create UNIX socket (12)

问题描述

SQLSTATE[HY000] [2001] Can't create UNIX socket (12)

在我的本地计算机上，我的项目运行正常.将更改推送到服务器后，我会收到此错误消息.

On my local machine my project works fine. As soon as I pushed my changes to the server I get this error message.

mysql日志完全为空.

The mysql log is totally empty.

Mysql配置: my.cnf

但是，使用相同mysql服务器的另一个站点也可以正常工作.

However another site that uses the same mysql server works fine.

以下是更多信息:我的vServer运行ubuntu 10.04，并具有2 GB的RAM.

推荐答案

这是

This is CR_SOCKET_CREATE_ERROR, an error generated by the client code.

12位可能是您客户的errno.您的系统上的错误12是什么?对我来说，使用mysql perror命令行实用程序，它是操作系统错误代码12:无法分配内存"

The 12 is probably your client's errno. What is error 12 on your system? For me, using the mysql perror command line utility, it's "OS error code 12: Cannot allocate memory"
