What version of MongoDB is installed on Ubuntu

Hi I'm a bit of a shell n00b.

Can anyone tell me how I would check the version of MongoDB that is installed on my Linux Ubuntu machine?

I see that my MongoDB shell version: 1.2.2 so Im pretty sure that MongoDB itself is out dated too. And does anyone know of any 'How to update MongoDB' docs? I find mongodb.org to be a bit confusing.

Please and thank you.


Ok if I use db.version() inside of mongo shell it says 1.2.2

If I $ mongod --version I get this:

db version v1.2.2, pdfile version 4.5
Wed Oct 16 10:28:22 git version: nogitversion

I ran

sudo apt-get update
sudo apt-get install mongodb

and get

sudo apt-get install mongodb
Reading package lists... Done
Building dependency tree

mongodb is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 179 not upgraded.

mongod --version
db version v1.2.2, pdfile version 4.5
Wed Oct 16 10:31:07 git version: nogitversion

So why isn't it updating? Is apt-get pointing at the wrong repo / source?


Solution 1:

inside shell:

$ mongod --version

Solution 2:

To be complete, a short introduction for "shell noobs":

First of all, start your shell - you can find it inside the common desktop environments under the name "Terminal" or "Shell" somewhere in the desktops application menu.

You can also try using the key combo CTRL+F2, followed by one of those commands (depending on the desktop envrionment you're using) and the ENTER key:

xfce4-terminal
gnome-console
terminal
rxvt
konsole

If all of the above fail, try using xterm - it'll work in most cases.

Hint for the following commands: Execute the commands without the $ - it's just a marker identifying that you're on the shell.

After that just fire up mongod with the --version flag:

$ mongod --version

It shows you then something like

$ mongod --version
db version v2.4.6
Wed Oct 16 16:17:00.241 git version: nogitversion

To update it just execute

$ sudo apt-get update

and then

$ sudo apt-get install mongodb

ANSWER: Read the instructions #dua

Ok the magic was in this line that I apparently missed when installing was:

$ sudo apt-get install mongodb-10gen=2.4.6

And the full process as described here http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/ is

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
$ echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
$ sudo apt-get update
$ sudo apt-get install mongodb-10gen
$ sudo apt-get install mongodb-10gen=2.2.3
$ echo "mongodb-10gen hold" | sudo dpkg --set-selections
$ sudo service mongodb start

$ mongod --version
db version v2.4.6
Wed Oct 16 12:21:39.938 git version: b9925db5eac369d77a3a5f5d98a145eaaacd9673

IMPORTANT: Make sure you change 2.4.6 to the latest version (or whatever you want to install). Find the latest version number here http://www.mongodb.org/downloads
