Apache - how to change the document root directory

Apache - how to change the document root directory

https://help.ubuntu.com/community/ApacheMySQLPHP

Apache2 has the concept of sites, which are separate configuration files that Apache2 will read. These are available in /etc/apache2/sites-available. By default, there is one site available called 000-default. This is what you will see when you browse to http://localhost  orhttp://127.0.0.1. You can have many different site configurations available, and activate only those that you need.

As an example, we want the default site to be /home/user/public_html/. To do this, we must create a new site and then enable it in Apache2.

To create a new site:

• Copy the default website as a starting point. sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/mysite.conf 
• Edit the new configuration file in a text editor "sudo nano" on the command line or "gksudo gedit", for example:gksudo gedit /etc/apache2/sites-available/mysite.conf
• Change the DocumentRoot to point to the new location. For example, /home/user/public_html/
• Change the Directory directive, replace  to 
• You can also set separate logs for each site. To do this, change the ErrorLog and CustomLog directives. This is optional, but handy if you have many sites
• Save the file

Now, we must deactivate the old site, and activate our new one. Ubuntu provides two small utilities that take care of this: a2ensite (apache2enable site) and a2dissite (apache2disable site).

$ sudo a2dissite default && sudo a2ensite mysite

Finally, we restart Apache2:

$ sudo /etc/init.d/apache2 restart

If you have not created /home/user/public_html/, you will receive an warning message

To test the new site, create a file in /home/user/public_html/:

$ echo 'Hello! It is working!' > /home/user/public_html/index.html

Finally, browse to http://localhost/
