Unable to start mongodb-community

I am trying to install Mongodb on my Mac (M2 chip)

I run the following:

brew tap mongodb/brew
brew install [email protected]
brew services start [email protected]

I then check if the service is running and check the logs

➜  brew services list
Name              Status       User  File

Any idea what that log shows?

I tried a few other things:

    The log you provided from MongoDB indicates that the mongodb server is starting up but then shuts down immediately.

    The log entries related to ‘WiredTiger’ sho wthat Mongodb’s storage engine is closing and shuting down. WiredTiger is the default storage engine user by mongodb

    {"t":{"$date":"2024-08-07T17:23:20.516+08:00"},"s":"I",  "c":"STORAGE",  "id":4795902, "ctx":"initandlisten","msg":"Closing WiredTiger","attr":{"closeConfig":"leak_memory=true,use_timestamp=false,"}}


{"t":{"$date":"2024-08-07T17:23:20.570+08:00"},"s":"I",  "c":"STORAGE",  "id":4795901, "ctx":"initandlisten","msg":"WiredTiger closed","attr":{"durationMillis":54}}

    The exit code 62 generally indicated that mongodb encountered an error during startup or shutdown.

    {"t":{"$date":"2024-08-07T17:23:20.570+08:00"},"s":"I",  "c":"CONTROL",  "id":23138,   "ctx":"initandlisten","msg":"Shutting down","attr":{"exitCode":62}}

    Potential causes:

    • File system permission
    • Conflicting processes
    • Configuration issues

    Try uninstall and re-install mongodb. But this time try this command,

    brew update
brew uninstall mongodb-community
brew install mongodb-community

    or
    brew update
    brew uninstall [email protected]
    brew install [email protected]

    brew services start [email protected]

    To check if it has started,

    ps aux | grep -v grep | grep mongod

    Just in case you can do it this operation with sudo

    From https://www.mongodb.com/docs/manual/reference/exit-codes/ the code 62 is…

    Returned by mongod when the datafiles in –dbpath are incompatible with the version of mongod currently running.

    To resolve data incompatibility issues after upgrading, please refer to the release notes for your version of MongoDB and search for "Changes Affecting Compatibility."

    The simples way to prove it is correct is to create an empty /opt/homebrew/var/mongodb_test and change /opt/homebrew/etc/mongod.conf to point dbPath to that location.

    Mongo will initialise the wt files on first run.
