I recently come accros this situation, when i start the mognod service, i was getting the below error.
[root@ip-xx-xx-xxx-xx mongo]# /etc/init.d/mongod start
Starting mongod: about to fork child process, waiting until server is ready for connections.
forked process: 19972
all output going to: /var/log/mongo/mongod.log
ERROR: child process failed, exited with error number 45
[FAILED]
[root@ip-xx-xx-xxx-xx mongo]# /etc/init.d/mongod restart
Stopping mongod: [FAILED]
Starting mongod: about to fork child process, waiting until server is ready for connections.

To fix this issue, I got some fixes to repair the mongodb instance. So in screeen i tried the repair command with the mongodb db path(in my case it is /var/lib/mongo/ ),
[root@ip-xx-xx-xxx-xx mongo]# mongod --dbpath /var/lib/mongo/ --repair
Then i run
[root@ip-xx-xx-xxx-xx mongo]# mongod --dbpath /var/lib/mongo/&
This will fix the issue partially, mongodb service will start after this. But this is not the actual fix to this issue.
This is an error due to the permission on the db path of mongodb.
In my case when i check, the location /var/lib/mongo it was owned by root and group root. We need to chnage this to mongod
So i ran this command and fixed the issue.
[root@ip-xx-xx-xxx-xx mongo]# cd /var/lib/
[root@ lib]# chown -R mongod.mongod mongo
Then you can start the mongod service.
[root@ip-xx-xx-xxx-xx mongo]# /etc/init.d/mongod start
