MongoDB Installation and Usage On MacOS

mongo-setup-macos.md

1. Install mongodb community edition
2. Install and configure mongosh
3. Create a configuration file /etc/mongod.conf (you may need to create it with sudo). Copy the following snippet and replace <username> with your username and paste it:

processManagement:
   fork: true
net:
   bindIp: localhost
   port: 27017
storage:
   dbPath: /Users/<username>/data/db
systemLog:
   destination: file
   path: "/Users/<username>/data/log/mongodb/mongod.log"
   logAppend: true
storage:
   journal:
      enabled: true

4. Open ~/.bash_profile and append the followin bash snippet

alias mongodstart="mongod --config /etc/mongod.conf"

mongod_stop() {
 local mongopid=`less ~/data/db/mongod.lock`;
 if [[ $mongopid =~ [[:digit:]] ]]; then
     sudo kill -15 $mongopid;
     echo mongod process $mongopid terminated;
 else
     echo mongod process $mongopid not exist;
 fi
}

alias mongodstop="mongod_stop"

5. Run source ~/.bash_profile
6. Start and stop mongod server using mongodstart and mongodstop command
7. Once the deamon started successfully, run mongosh to connect to your local mongodb database (You can use mongo but mongosh is better!^*)
