Install MongoDB on Debian¶
　　This tutorial outlines the steps to install MongoDB on Debian systems. The tutorial uses .deb packages to install. While some Debian distributions include their own MongoDB packages, the official MongoDB packages are generally more up to date.



NOTE
This tutorial applies to both Debian systems and versions of Ubuntu Linux prior to 9.10 “Karmic” which do not use Upstart. Other Ubuntu users will want to follow the Install MongoDB on Ubuntu tutorial.



Package Options
　　The downloads repository provides the mongodb-10gen package, which contains the latest stablerelease. Additionally you can install previous releases of MongoDB.
　　You cannot install this package concurrently with the mongodb, mongodb-server, or mongodb-clients packages that your release of Debian may include.



Install MongoDB



Configure Package Management System (APT)
　　The Debian package management tools (i.e. dpkg and apt) ensure package consistency and authenticity by requiring that distributors sign packages with GPG keys.






1


Import MongoDB PGP key.
　　Issue the following command to add the MongoDB public GPG Key to the system key ring.





sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10







2


Create a sources.list file for MongoDB.
　　Create a /etc/apt/sources.list.d/mongodb.list file





echo 'deb http://downloads-distro.mongodb.org/repo/debian-sysvinit dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list







3


Reload local package database.
　　Issue the following command to reload the local package database:





sudo apt-get update




Install Packages
　　Issue the following command to install the latest stable version of MongoDB:





sudo apt-get install mongodb-10gen

　　When this command completes, you have successfully installed MongoDB!



Manage Installed Versions
　　You can use the mongodb-10gen package to install previous versions of MongoDB. To install a specific release, append the version number to the package name, as in the following example:





apt-get install mongodb-10gen=2.2.3

　　This will install the 2.2.3 release of MongoDB. You can specify any available version of MongoDB; however apt-get will upgrade the mongodb-10gen package when a newer version becomes available. Use the following pinning procedure to prevent unintended upgrades.
　　To pin a package, issue the following command at the system prompt to pin the version of MongoDB at the currently installed version:





echo "mongodb-10gen hold" | sudo dpkg --set-selections




Control Scripts
　　The packages include various control scripts, including the init script /etc/rc.d/init.d/mongodb. These packages configure MongoDB using the /etc/mongodb.conf file in conjunction with the control scripts.
　　As of version 2.4.9, there are no control scripts for mongos. mongos is only used in sharding deployments. You can use the mongod init script to derive your own mongos control script.



Run MongoDB
　　The MongoDB instance stores its data files in the /var/lib/mongo and its log files in/var/log/mongo, and run using the mongod user account. If you change the user that runs the MongoDB process, you must modify the access control rights to the /var/lib/mongo and /var/log/mongodirectories.



Start MongoDB
　　Issue the following command to start mongod:





sudo /etc/init.d/mongodb start

　　You can verify that mongod has started successfully by checking the contents of the log file at/var/log/mongodb/mongodb.log.



Stop MongoDB
　　Issue the following command to stop mongod:





sudo /etc/init.d/mongodb stop




Restart MongoDB
　　Issue the following command to restart mongod:





sudo /etc/init.d/mongodb restart
