Error "mongod dead but pid file exists"

Question

I am not able to start mongodb when I execute "/etc/init.d/mongod status " I got message "mongod dead but pid file exists" i am new to mongodb Please help me out.

Answer 1

To get more info on why mongod is not starting successfully, you can check the mongodb log file for any errors. On CentOS, this file is most likely in /var/log/mongodb/mongodb.log.

When this occurred for us once, it pointed to a permissions issue:

ERROR: listen(): bind() failed errno:13 Permission denied for socket: /tmp/mongodb-27017.sock

This error can be resolved by setting the correct permissions on the /tmp directory, which is already answered in this Stackoverflow question: MongoDB - Permission denied for socket: /tmp/mongodb-27017.sock

Hope that helps!
