starting mongodb

[lewashby]

When I tried to start MongoDB with the mongod command I got the following.

garrett@mint-desktop ~ $ mongod
mongod --help for help and startup options

I then ran sudo mkdir /data/db and now I'm getting this.

Any ideas?

Okay so I fixed that and now I'm getting this.
Sun Jan 10 14:57:42.529 [initandlisten] ERROR: listen(): bind() failed errno:98 Address already in use for socket: 0.0.0.0:27017
Sun Jan 10 14:57:42.529 [websvr] ERROR: listen(): bind() failed errno:98 Address already in use for socket: 0.0.0.0:28017
Sun Jan 10 14:57:42.529 [initandlisten] ERROR: addr already in use

So now I'm having to start MongoDB with using mongod --port 28018 instead of the default 28017. How can I figure out what's using the port that MongoDB is also wanting to use? Thanks.

You can run netstat with these options:

sudo netstat -tulpn |grep -E ':[0-9]{5}'

Or simply search for a specific port number:

sudo netstat -tulpn |grep :28017

It should return something like:

...
tcp    0    0 0.0.0.0:17500    0.0.0.0:*    LISTEN    3374/dropbox
...

You can get more information about the process by checking the identifier in the /proc/ directory:

ls -lh /proc/3374/exe

this should return the path. More information here:
