See Official MongoDB install docs for all platforms.
See getting started with MongoDB for an overview of what MongoDB is.
1. Import Key
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5
2. Create List file
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list
3. Reload package database
sudo apt-get update
4. Install Mongoddb packages
We install a specific version of Mongdodb (
3.6.2) here because then we know exactly what we're dealing with. Just pulling the latest version is great, but knowing what version your deployments are running can reduce ambiguity and bug chasing.
sudo apt-get install -y mongodb-org=3.6.2 mongodb-org-server=3.6.2 mongodb-org-shell=3.6.2 mongodb-org-mongos=3.6.2 mongodb-org-tools=3.6.2
Pin a specific version of MongoDB.
apt-get upgrade from auto upgrading mongodb. There's two sides to this, it's great we've pinned the version and prevented auto updates- which might prevent breakage. But who's in control of patch managements and making sure you're up to date on that. Have a plan.
echo "mongodb-org hold" | sudo dpkg --set-selections echo "mongodb-org-server hold" | sudo dpkg --set-selections echo "mongodb-org-shell hold" | sudo dpkg --set-selections echo "mongodb-org-mongos hold" | sudo dpkg --set-selections echo "mongodb-org-tools hold" | sudo dpkg --set-selections
Note the official install docs point out all packages need to be marked as
hold to keep them from being updated.
MongoDB default directory on Ubuntu
Now you've installed MongoDB, good to know where everything is.
- Data files:
- Log files:
- The MongoDB process / daemon runs as
Verify MongoDB Installation
1. Start your MondoDB instance
sudo service mongod start
2. Verify it started successfully
Use tail to look at the end of the log:
tail -f /var/log/mongodb/mongod.log
On the end of the log file you should see somthing like:
2018-01-13T16:37:26.954+0000 I FTDC [initandlisten] Initializing full-time diagnostic data capture with directory '/var/lib/mongodb/diagnostic.data' 2018-01-13T16:37:26.954+0000 I NETWORK [initandlisten] waiting for connections on port 27017
Specifically, "waiting for connections on port 27017".
3. How to stop/restart MondoDB
sudo service mongod stop
sudo service mongod restart
4. Connect to MongoDB cli
mongo --host 127.0.0.1:27017
Will give you a shell, becaue MongoDB listens on the loopback address (127.0.0.1) by default.
To purge and remove MongoRB, see the end of the official mongoDB install docs.
Done. Now why not deploy a replica set with authentication!?
