标签： mongodb nginx centos

【解决方案1】：

尝试删除此文件：/tmp/mongodb-27017.sock

然后重启服务:)

【讨论】：

它是一个监听套接字文件，允许本地连接到 MongoDB，而无需产生 TCP/UDP 连接。它应该在您自动停止 Mongo 时删除，并在启动时创建。

【解决方案2】：

让这个死而复生。

运行 mongod 的用户需要 /tmp 目录的权限。为避免这种情况，您可以应用配置设置来更改创建 mongodb-.sock 文件的位置。用户已经可以访问他们的主文件夹，所以这对我有用。

net:
  port: 27017
  unixDomainSocket:
    pathPrefix: /home/vagrant/config0
