I am installing mongodb on ubuntu terminal from this url (http://mongojs.org/install-mongodb-ubuntu-11-04-natty)

I am on the step where you type in ./mongod

when I type that I get the following: bash: ./mongod cannot execute binary file error

can someone help me get over this obstacle? thanks.

    Is that the limit of your error? What is the output of "ldd /usr/bin/mongod" and "/usr/bin/mongod -vvvv"? Commented Jul 13, 2012 at 9:02
  • ldd: no such file or directory<br />-ww:<br />ldd: .-ww no such file or directory Commented Jul 13, 2012 at 15:56
  • Where is mongod installed? "which mongod" What happens when you run it in verbose mode? Commented Jul 13, 2012 at 16:19
  • can you explain what verbose mode means? it is installed in /home/mongodb-linux-x86_64-2.0.6 Commented Jul 13, 2012 at 16:28
  • With the "-vvvv" option above. So run /home/mongodb-linux-x86_64-2.0.6/bin/mongod -vvvv please. Also ldd should be in /usr/bin or maybe /usr/sbin. Can you also run "/usr/bin/ldd /home/mongodb-linux-x86_64-2.0.6/bin/mongod"? Commented Jul 13, 2012 at 16:44

My only suggestion would be to check you're using the correct version (32-bit vs 64-bit). The link provided in the tutorial is 64-bit, which won't work if you're using a 32-bit machine.

This is probably caused by an invalid installation. Follow the following steps on ubuntu to install Mongodb properly:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10 echo "deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen" | sudo tee --append /etc/apt/sources.list.d/10gen.list sudo apt-get update sudo apt-get install mongodb-10gen

With this, you can now start your local mongo instance. Make sure to update your config file to change your data directory to where you want to have the DB files stored.

  • Did you actually read the link user1522901 posted? Those are the actual steps he/she claims to have followed. Commented Jul 14, 2012 at 19:29
  • Mark, based on the error, I think it was safe to assume he did not use the package manager, but rather the manual option in the link he provided. It seems to me like he's missing some dependencies which would be resolved by installing using apt-get. Commented Jul 14, 2012 at 19:43
  • Well he/she said that he/she did. I don't think apt-get will resolve that error. Regardless of that, you should have added it as a comment, not an answer. Commented Jul 14, 2012 at 19:47
