MongoDB 没有连接到服务器 127.0.0.1:27017 并显示目标机器主动拒绝它

Question

I run this command C:\Program Files\MongoDB\Server\4.2\bin\mongo.exe start my mongoDB but it is showing this error:

MongoDB shell version v4.2.5

My mongoDB compass isn't connecting too..

Answer 1

mongo ( mongo.exe for windows users) does not start the server. It is used to connect to a server which is already running.

Answer 2

You should run mongod in the command line before connecting to the server, it will initialite it. You can't connect to the server you haven't started

Answer 3

Try to comment out this last line mp at \bin\mongodb.cfg. becomes #mp: Restart mongod.

You can check whether your mongodb is running at the service (task Manager->Services ->Mongodb)..(Make sure you click Property to see all those setting)

Hope this helps.
