How To Install MongoDB on Ubuntu 12.04

cool! this works for me after I install mongodb and i get this error after updating:

W: GPG error: http://downloads-distro.mongodb.org dist Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 9ECBEC467F0CEB10

You may be reaching this error because the GPG key, which is specified in the first line of the script, is transferred through port 11371. It is possible that this port may be blocked in your firewall setup.

I would recommend looking at your IP tables and, if it applies, unblocking port 11371. You can see your IP Table rules with the command “iptables -L” Let us know if you have further issues.

I have done this step by step… I even got the same results as you specified!!.. but whenever I say aarti@aarti-Vostro-1540:~$ mongo MongoDB shell version: 2.2.0 connecting to: test Thu Sep 13 11:38:30 Error: couldn’t connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91 exception: connect failed aarti@aarti-Vostro-1540:~$

It may be that Mongo is not turned on.

Before using the “mongo” command, go ahead and start mongo running with “sudo service mongodb start”

Let me know if that works.

I ran sudo service mongodb start and it said it was already running. I typed mongo after that and everything was peachy. Very strange.

I believe it only creates the data directory on the first start but then exits. So, once you restart it once it works like a charm!

I followed the docs manual off mongodb.org works like a charm!

if you are getting an error trying to install a recent version on mongodb, check this out: https://jira.mongodb.org/browse/SERVER-6910

PLEASE add the fact to setup iptables!! otherwise your mongodb server will be open to the world! (default port and default auth)

apparently, when when I finish the step two, the mongo db has already created and ready to go. No step 3 is needed. Also looks like I need to replace user name and password immediately after creating the mongo db.

Run the lines of the bash script seperately and then run sudo service start mongodb.

Hi, thanks for this tutorial! I run this: “sudo service mongodb start” and mongo is started after I wanted to use the mongo shell so I run “mongo” but the answer was: “MongoDB shell version: 2.4.6 connecting to: test Sat Sep 14 19:24:36.797 Error: couldn’t connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145 exception: connect failed” so I suppose I should to change ip. but where?

@info: What’s the output of this command?

<pre>sudo netstat -plutn | grep 27017</pre>

Simple Step of installation there is no need to know more about detail if you only want installation copy and paste on terminal 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

I have disabled the root user after I created my “newuser” and can therefore not transfer any files to the /home/ directory, only to /home/newuser/. Can I run $ sudo bash ./mongo_install.bash from /home/newuser/ instead? Just like $ sudo bash .newuser/mongo_install.bash Or how shall I do?

And if I create a new VPS user I still want to be able to access mongodb from that user. Shall I just install as nanhe4it mention above as I can’t transfer the install script with filezilla to root (as it’s disabled)? And if yes, do I need to do anything additional to make mongodb start right back if I need to reboot my Droplet etc?

@Asterix: It doesn’t matter which user you install MongoDB as, it’s installed as a system service and can be accessed by all users once it’s installed. You only need to run sudo bash ./mongo_install.bash as a user with sudo access.

Ok, I now uploaded the install script to /home/newuser/ (I can’t upload the script to /home/ as it’s owned by the root user which is disabled) I then ran sudo bash ./mongo_install.bash And I got following errors: Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret -keyring /tmp/tmp.QTCMmtuUqA --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/ apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubu ntu.com --recv 7F0CEB10 " not a key ID: skipping deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen E: Invalid operation update Reading package lists… Done Building dependency tree Reading state information… Done ’ in directory ‘/etc/apt/sources.list.d/’ as it has an invalid filename extensio n ’ in directory ‘/etc/apt/sources.list.d/’ as it has an invalid filename extensio n E: Unable to locate package mongodb-10gen

@Asterix: What’s the output of <code>cat /path/to/mongo_install.bash | curl -F ‘sprunge=<-’ http://sprunge.us</code>?

Hmm, I got nothing. I ran newuser@servername:~$ cat /path/to/mongo_install.bash | curl -F 'sprunge=?

Well all I got was the “>”

I mean I ran cat /home/newuser/mongo_install.bash | curl -F 'sprunge=? but no output except for the “>” And I can see my install script mongo_install.bash in /home/newuser/ It has file permission 664 though owned by newuser,

When I followed http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/ it suddenly seems to work but I get following: “’ in directory ‘/etc/apt/sources.list.d/’ as it has an invalid filename extension” at the end. What is that?

Setting up mongodb-10gen (2.4.6) … Adding system user mongodb' (UID 105) ... Adding new user mongodb’ (UID 105) with group nogroup' ... Not creating home directory /home/mongodb’.

When I run sudo service mongodb start I get: start: Job is already running: mongodb

When I run newuser@servername:~$ mongo I get MongoDB shell version: 2.4.6 connecting to: test but when I run $ps -ef | grep mongo I get: -bash: -ef: command not found

Ah now it finally worked!!

ps -ef | grep mongo mongodb 709 1 0 05:10 ? 00:01:02 /usr/bin/mongod --config /etc/mo ngodb.conf 1000 2083 1942 0 11:21 pts/0 00:00:00 grep --color=auto mongo

@Asterix: My bad, the second half of the command got stripped out because of the filtering system.

Is it all fine now?

Using Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux I got following error.

Any suggestion?

@grega.vrbancic: This article does not work on Debian. See <a href=“http://docs.mongodb.org/manual/tutorial/install-mongodb-on-debian/”>http://docs.mongodb.org/manual/tutorial/install-mongodb-on-debian/</a>

Great tutorial, step 3 seems to be superfluous on ubuntu 12 though. Got a

mongodb start/running, process 6315

after running

sudo apt-get -y install mongodb-10gen

I created the bash script, but upon running it I get the following error:

Package mongodb-10gen is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

E: Package ‘mongodb-10gen’ has no installation candidate

I then tried using ‘sudo apt-get install mongodb-org’ (with or without -y) but it didn’t work either (E: Unable to locate package mongodb-org).

Maybe the package mongodb-10gen has been obsoleted?

whoops, I got it. it must have been a typo or something like that.

If you are getting the following error when running the bash script:

“WARNING: The following packages cannot be authenticated!”

Then you simply need to modify the last two lines of the script to:

apt-get -y --force-yes update apt-get -y --force-yes install mongodb-10gen

Everything should work fine after that.

Thanks for this, but I just tried it and got v2.4.1 installed, not the latest.

The instructions from 10gen here work.

Looks like they changed the name of their package for the latest release.

I concur - it would save time to have the last comment appear first.

Every now and than it looks like mongodb stops running.

When I

sudo service mongod start

It starts again.

Is there a way to auto start or check and auto start mongodb?
