Mongodb 服务器无法启动

Question

我按照 mongodb 官方安装指南来信 here 到目前为止我尝试过的东西

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

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"}
}

这是一个文件权限问题。

您将需要修复所指出文件的权限。
