之前用的一直很正常，直到昨天我重新打开了一下armitage的时候发现无法链接psql了，我就去看了下msf，发现数据的链接出现了异常：
msf5 > db_status
[*] postgresql selected, no connection
然后我就重新刷新了一下数据库信息，给我报了一大堆的错误：

其实最关键的是这个问题，导致我现在就是打都打不开psql新建账户啥的都有问题了:
psql: 错误: 无法连接到服务器：无法联接到服务器: 没有那个文件或目录
服务器是否在本地运行并且在 Unix 域套接字
"/var/run/postgresql/.s.PGSQL.5432"上准备接受联接?
有没有大佬知道这个问题如何解决？
如果实在不行的话呢我只能恢复镜像了，但是太多东西都就没了...
，原因其实挺简单的
