单神服务器不会启动

Question

我遵循了mongodb官方安装指南，直到现在我尝试了从这里的东西到信件。

1. 删除和重新安装mongodb
2. 尝试使用mongodb包(mongodb包也不会以输出mongod.service启动)

这是我得到的输出

Answer 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= Error。

如果您查找该日志中的第一个错误，您将看到它是：

{
   "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。

您将需要修复指定文件的权限。
