Create nudge structure

sudo mkdir -p /etc/nudge  
sudo mkdir -p /var/log/nudge  
sudo mkdir -p /usr/lib64/php/modules    

Move files in the right places

The parent folder of nudge.ini may vary, it depends of your Linux OS:

Distribution	Répertoire
Redhat (or like)	`/etc/php.d`
Ubuntu, Debian (or like)	`/etc/php5/apache2/conf.d/`

sudo mv nudge.ini /etc/php.d
sudo mv config.cfg logger.properties /etc/nudge
sudo mv nudge.so /usr/lib64/php/modules
sudo mv nudge-agent /usr/bin

Set up permissions

sudo chmod +x /usr/bin/nudge-agent
sudo chmod +w /var/log/nudge

Warning : if SELinux is activated, you must authorize the Nudge PHP module :

  sudo chcon system_u:object_r:textrel_shlib_t /usr/lib64/php/modules/nudge.so

Set your nudge app key in the /etc/php.d/nudge.ini file

The key is composed by your application folder path and the Nudge key.
Example:
```
nudge.apps=/var/www/myapp:c5e9230c-3927-4c53-829d-8d87dbeff
```

Look at the log folder : /var/log/nudge, you should see this two files :
