Our xdebug configuration in the Vagrant machine

From this article: Vagrant: A box with Drupal 7 simpleSAMLphp. We have xdebug installed in our Vagrant machine. 

Let's configure it. Connecting to the Vagrant Machine.

$ cd vagrantrepo & vagrant ssh

Editing 'php.ini'. In the vagrant machine we'll edit 20-xdebug.ini since it is where Nginx is storing the xdebug settings

sudo vi /etc/php5/fpm/conf.d/20-xdebug.ini

zend_extension=xdebug.so
xdebug.remote_enable = on
xdebug.remote_connect_back = on
xdebug.idekey = "vagrant"

Restarting Ngix

sudo service php5-fpm restart

Debuging from SublimeText or PHPStorm: 

I don't want to dive into how to install and enable xdebug in SublimeText or PHPStorm. 

Follow the following tutorial for ST: webdevstudios.com

And this one for PHPStorm: https://confluence.jetbrains.com/

Tunneling into the remote server 

We have two "ways" to create the tunnel to the Vagrant machine. 

1.- Using the regular ssh command

ssh -R 9000:localhost:9000 vagrant@192.168.33.99; the password is 'vagrant' as usual. 

2.- Using the vagrant ssh command

vagrant ssh -- -R 9000:localhost:9000
 
Don't forget to execute it from the Vagrant repo/folder.

We are absolute sure that the tunnel is stablished executing $ netstat -nlt | grep 9000. The output should look like this:

tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN     
tcp6       0      0 ::1:9000                :::*                    LISTEN 

If still the above output is blank. Try disabling the FireWall

sudo ufw disable

TODOs

Open FW only for the port 9000.
