Mongod cannot execute in ubuntu

binaryexecutionmongodb

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.

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.

Ubuntu – How to upgrade mongodb 1.8 to 2.2 on ubuntu

You can overwrite the MongoDB binaries, that will work fine

However, there is no possible way you installed version 1.2.2 - that version is not available on the repositories mentioned in the installation instructions (and it is ancient - from Jan 2010) - the only versions are 1.8, 2.0 and 2.2.

You may be confusing it with a driver version - PHP maybe?

If you run /usr/lib/mongodb/mongod --version it will tell you the version of mongod that is actually installed.

If you installed one of the lower versions and want to upgrade, I would recommend just removing the older package:

sudo apt-get remove mongodb18-10gen

Then install the latest stable release (as of writing that would be 2.2.2):

sudo apt-get install mongodb-10gen

MongoDB server crashed, showing the following error

Looks like you're OK, but FYI: this just happened to me. Pretty much the same stack trace. The problem was that as I was restarting mongod, my current directory in this shell happened to be one which I had deleted a little while ago (in another shell). That was why getcwd was failing.
