Install MongoDB in Debian

As a part of Sitecore 8 setup, we need to install MongoDB in Debian.

1. Check Debian version. The MongoDB 3.xx requires at least Debian 7.1
   
   
   
   
   
   
2. So we need to upgrade to Debian 7.1 at least. Here is how to do it.
   
   Edit your /etc/apt/sources.list file and change all instances of squeeze to wheezy. Once you have finished, your /etc/apt/sources.list should resemble the following:
   
   

      /etc/apt/sources.list

   
   
   

     
   deb http://ftp.us.debian.org/debian/ wheezy main
   deb-src http://ftp.us.debian.org/debian/ wheezy main
   
   deb http://security.debian.org/ wheezy/updates main
   deb-src http://security.debian.org/ wheezy/updates main
   
   # wheezy-updates, previously known as 'volatile'
   deb http://ftp.us.debian.org/debian/ wheezy-updates main
   deb-src http://ftp.us.debian.org/debian/ wheezy-updates main

3. Go through the update process.
   
   Enter the following command to update your package lists:
   

   apt-get update

   
   Keep getting the error of " GPG error: http://ftp.us.debian.org wheezy Release: The following signatures couldn't be verified because the public key is not available: Try this and ignore the warning.
   

   apt-get install debian-archive-keyring

More info: http://serverfault.com/questions/337278/debian-how-can-i-securely-get-debian-archive-keyring-so-that-i-can-do-an-apt-g
4. Enter the following command to grab the latest versions of key system utilities:

apt-get install apt dpkg aptitude

5. After the package updates have completed, upgrade your system by entering the following command. The upgrade will download and install numerous packages. This step may take a while to complete.

   apt-get dist-upgrade

   
   
   
6. After "reboot", check the debian version again. 
           cat /etc/debian_version
1. 
   

   
   

Install MongoDB

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

Import the public key used by the package management system.

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

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

Create a /etc/apt/sources.list.d/mongodb-org-3.0.list file for MongoDB.

Create the list file using the following command:

echo "deb http://repo.mongodb.org/apt/debian "$(lsb_release -sc)"/mongodb-org/3.0 main" | tee /etc/apt/sources.list.d/mongodb-org-3.0.list

If your Debian installation does not have lsb_release installed, you may install it using sudoapt-get install lsb-release.

Reload local package database.

Issue the following command to reload the local package database:

apt-get update

Install the MongoDB packages.

You can install either the latest stable version of MongoDB or a specific version of MongoDB.

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8

locale-gen en_US.UTF-8
export LC_ALL=en_US.UTF-8

dpkg-reconfigure locales

Install the latest stable version of MongoDB.

Issue the following command:

sudo apt-get install -y mongodb-org 

Install a specific release of MongoDB.

Specify each component package individually and append the version number to the package name, as in the following example:

3.0.2 mongodb-org-server=3.0.2 mongodb-org-shell=3.0.2 mongodb-org-mongos=3.0.2 mongodb-org-tools=3.0.2

If we get this error as below, go to

[FAIL] Starting database: mongod failed! invoke-rc.d: initscript mongod, action "start" failed. dpkg: error processing mongodb-org-server (--configure):  subprocess installed post-installation script returned error exit status 1 Setting up mongodb-org-mongos (3.0.2) ...

Make sure remove "/tmp/mongodb-27017.sock" if there is any.

Also, go to "/var/log/mongodb/mongod.log" to see the logs.

If the log showing insufficient space related error.

Put "smallfiles=true" in the etc/mongod.conf to get over it for now and raise up with CAV to give more spaces for the related path.
