MongoDB Service Will Not Start After Initial Setup

Question

I am running Fedora 20 and installed MongoDB per the Red Hat installation guide on the official documentation. I was able to run the mongod daemon as a service with

Answer 1

I just experience a similar problem on ubuntu. Encountered nearly every ERROR tips, like

child process failed, exited with error number 1

orchild process failed, exited with error number 100

or [signalProcessingThread] got signal 2 (Interrupt: 2), will terminate after current cmd ends

For many times I remove the Mongodb and try to install again, but the problem remains....

Finally I came to this way: Backup your data first, then remove Mongodb with

#sudo apk-get autoremove mongodb-org

Find out all the files related with mongodb:

/#find -name mongo*

Delete them all with "rm" or "rmdir", including the packages in the /var/cache/... and everthing.

Then repeat the installation as the first time you did :

#echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
#sudo apt-get update
#sudo apt-get install -y mongodb-org

It will run again.
