Find out from netstat which process is running mongodb port (27017)

command:

<pre><code>sudo netstat -tulpn | grep :27017

Output will be:

In my case "6432" is the pid, it may be different in your case.

I've faced the same issue. Though the <code>mongodb</code> service is not running, the log showed <code>address already in use</code> message.

<pre><code> $netstat -tulpn | grep :27017

returns nothing

On further analysis found that the issue was due to lock file. The service is running fine, after deleting the lock file and restarting it.

<pre><code>$grep "dbpath" /etc/mongodb.conf

dbpath =/var/lib/mongodb

$ls /var/lib/mongodb/mongod.lock

MongoDB unable to start is mainly due to unclean shutdown. To remedy, delete the mongod.lock file. This file is located in the data folder. 

Find out where your data folder is by looking in the mongodb.conf or mongod.conf file. (Conf file under /etc on Linux systems.)

<pre><code># Where and how to store data.
storage:
 dbPath: /var/lib/mongodb

For example using the above configuration, the file is at /var/lib/mongodb/mongod.lock. Simply remove it and restart mongodb.
