MongoDB - WARNING: shell and server versions do not match

Question :

Getting this WARNING when logging on to mongo

MongoDB shell version v3.4.9

connecting to: mongodb://127.0.0.1:27017/

MongoDB server version: 3.6.12

WARNING: shell and server versions do not match

I’ve restarted mongo which hasn’t fixed the issue .

Can I install manually or is this something pushed down from Ops Manager ?

Answer: In this situation there are two options

Copy the latest binary into /usr/bin or use the latest mongo shell version.

To get the information require , execute this command ps -ef | grep -i mongod

ps -ef | grep -i mongod
