When I somehow login and logout my linode vps where I start the service of mongodb for some times, then I got these errors: # service mongod startStarting mongod: Wed Oct 30 01:28:42.557Wed Oct 30 01:28:42.558 warning: 32-bit servers don't

When I somehow login and logout my linode vps where I start the service of mongodb for some times, then I got these errors:

# service mongod start
Starting mongod: Wed Oct 30 01:28:42.557
Wed Oct 30 01:28:42.558 warning: 32-bit servers don't have journaling enabled by default. Please use --journal if you want durability.
Wed Oct 30 01:28:42.558
about to fork child process, waiting until server is ready for connections.
forked process: 6873
all output going to: /var/log/mongo/mongod.log
ERROR: child process failed, exited with error number 100
 [FAILED]

So, after googling, I find the reason:

Unclean shutdown detected.
Please visit http://dochub.mongodb.org/core/repair for recovery instructions.

How to resolve it?

First, kill the process if it exists

ps -ef | grep mongo*
ps -ef | grep mongod
kill -9 pid

Second, remove the lock file for mongodb

rm -rf /var/lib/mongo/mongod.lock

Third, boot it with repair mode

mongod -f /etc/mongod.conf --repair

Forth, boot again without repair mode

mongod -f /etc/mongod.conf

Now we can check if the mongodb process is running:

ps -ef | grep mongo*
ps -ef | grep mongod

And try it: mongo

Done!
