【问题描述】：

我跟着mongodb官方安装指南看here的来信 到目前为止我尝试过的事情

删除并重新安装 mongodb 尝试使用 mongodb ubuntu 包（mongod 服务器也不会启动，输出 mongod.service 不存在）

这是我得到的输出

【问题讨论】：

检查您是否对 /tmp 有足够的权限，因为日志表明套接字文件存在一些权限问题。或者看起来更早，mongodb 是从 root 用户开始的。 "path":"/tmp/mongodb-27017.sock","error":"不允许操作"

【参考方案1】：

每个日志对象中的s 字段是消息的严重性：I = 信息，W = 警告，E = 错误。

如果您在该日志中查找第一个错误，您会看到它是：

   "t":"$date":"2021-04-13T13:09:20.763+05:30",
   "s":"E", 
   "c":"NETWORK", 
   "id":23024, 
   "ctx":"initandlisten",
   "msg":"Failed to unlink socket file",
   "attr":"path":"/tmp/mongodb-27017.sock","error":"Operation not permitted"
 

这是文件权限问题。

您需要修复记录文件的权限。

谢谢你，我发现什么不工作，使用 .deb 文件强制重新安装它并单独安装 mongo shell。
