Weird Error 8 - Ghost Blog on Centos 6.4

When I first install and run Ghost via npm start all is well with the initial config.js settings.

After following several tutorials/questions, I still keep running into the weird error 8 when I make any changes to the config.js

Installing Ghost on Centos 6.4

Ghost Docs

Any help/insight is much appreciated.

I have

• Reinstalled Ghost
• Restarted my Centos machine
• Tried with --production flag for npm start
• Tried editing the host/port in config to several options

With initial config.js

$ npm start --production

ghost@0.4.1 start /var/www/html/Projects/ghost.mydomain.name/ghost
node index

Ghost is running...
Your blog is now available on http://my-ghost-blog.com
Ctrl+C to shut down
^C
Ghost has shut down
Your blog is now offline

Now changing config to 0.0.0.0 and port 80

dev at centos64  /var/www/html/Projects/ghost.mydomain.name/ghost
$ npm start --production

ghost@0.4.1 start /var/www/html/Projects/ghost.mydomain.name/ghost
node index
