Mongodb error: couldn't connect to server 127.0.0.1:27017 connection refused

Question

I downloaded mongodb-bin and mongodb-tools-bin in AUR.I just typed sudo systemctl enable mongodb and just ran mongo.This is the error i got:

$ mongo
MongoDB shell version v5.0.5
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :

I saw somebody say to just delete /var/lib/mongodb/mongod.lock but when i checked there was no mongod.lock file
