Installing and running mongodb on a mac is very easy with homebrew:
brew tap mongodb/brew brew install mongodb-community brew services start mongodb-community
It runs on localhost as a non-root user. You can verify that mongodb is running by searching for mongod in your running processes and by checking for the logs:
ps aux | grep -v grep | grep mongod tail /usr/local/var/log/mongodb/mongo.log
mongo command to start a mongo shell to the running instance.
CTRL-D to exit the mongo shell.
The default data directory is /
usr/local/var/mongodb. It is created when mongodb is installed with homebrew. The path is set in
/usr/local/etc/mongod.conf. See the default configuration on my mac:
systemLog: destination: file path: /usr/local/var/log/mongodb/mongo.log logAppend: true storage: dbPath: /usr/local/var/mongodb net: bindIp: 127.0.0.1
Hope this helps!
