Edit: you should now use brew services start mongodb
, as in Gergo’s answer…
When you install/upgrade mongodb, brew will tell you what to do:
To have launchd start mongodb at login:
ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents
Then to load mongodb now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Or, if you don’t want/need launchctl, you can just run:
mongod
It works perfectly.
