DocumentRoot location in CentOS

The default location for the document root is /var/www/html when you first install Apache® on CentOS®:

     ~]# httpd -S 2>1
     VirtualHost configuration:
     *:80                   example.com (/etc/httpd/conf.d/example.com.conf:1)
     *:443                  is a NameVirtualHost
              default server linuxchamber.com (/etc/httpd/conf.d/example.com.conf:26)
              port 443 namevhost example.com (/etc/httpd/conf.d/example.com.conf:26)
                      alias www.example.com
              port 443 namevhost example.com (/etc/httpd/conf.d/ssl.conf:56)
     ServerRoot: "/etc/httpd"
     Main DocumentRoot: "/var/www/html" <---default location

Set this location in file /etc/httpd/conf/httpd.conf:

     ]# grep -i documentroot httpd.conf 

     #DocumentRoot: The directory out of which you will serve your
     DocumentRoot "/var/www/html"
         # access content that does not live under the DocumentRoot.

Note: You can choose another directory if desired, such as /home/example.com/public_html/.

You can also set a document root for individual virtual hosts:

     <VirtualHost *:80>
         ServerAdmin [email protected]
         DocumentRoot /var/www/example.com/ <--set here
         ServerName example.com
         ServerAlias www.example.com
         ErrorLog logs/example.com-error_log
         CustomLog logs/example.com-access_log common
            <Directory /var/www/example.com/>
              AllowOverride All
           </Directory>
     </VirtualHost>

Note: The directories for the virtual hosts must be located under the main DocumentRoot. If your DocumentRoot is /var/www/,
then the directories are set under it, as shown in the following example:

     /var/www/example.com/

If you change these files, restart Apache with the following commands:

     httpd -t
     service httpd reload

If you have multiple vhosts, organize and separate each document root, as shown in the folloiwng example:

     /var/www/vhosts/example.com/
     /var/www/vhosts/example2.com/
     /var/www/vhosts/example3.com/
