What version of MongoDB is installed on Ubuntu

问题:

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        Reading state information... Done 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?

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

inside shell:

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

When you entered in mongo shell using "mongo" command , that time only you will notice

MongoDB shell version v3.4.0-rc2 connecting to: mongodb://127.0.0.1:27017 MongoDB server version: 3.4.0-rc2 

also you can try command,in mongo shell , db.version()

In the terminal just enter the traditional command:

mongod --version
