The way to enable allow_url_fopen on a phpsuexec and a non-phpsuexec server is different. To enable allow_url_fopen server wide is a security risk, however, you can turn it ON for a single domain incase it is required.

Here how it needs to be done.

• On a non phpsuexec server:

Goto the /usr/local/apache/conf/ directory,

# cd /usr/local/apache/conf/userdata

create a ‘userdata’ directory if not there and then create a directory with the accounts username inside it. Finally, you have to create a file allowurl.conf in the newly created directory.

The complete path should look like:

# pico /usr/local/apache/conf/userdata/<username>/allowurl.conf

and add the following to the file

<IfModule mod_php5.c>  

php_admin_value allow_url_fopen On 

php_admin_value allow_url_include On 

</IfModule> 

Now, edit the Apache configuration file and scroll down to the VirtualHost entry of the domain. Include the path of the above created file in it, as shown below:

Include "/usr/local/apache/conf/userdata/<username>/allowurl.conf"

Save the file and rebuild the apache configuration

# /usr/local/cpanel/bin/apache_conf_distiller --update 

# /usr/local/cpanel/bin/build_apache_conf 

# /scripts/restartsrv httpd

This will enable allow_url_fopen for that domain.

• On a PhpSuExec Or SuPHP server:

To enable allow_url_fopen on a SuPHP/PHPSuExec enabled server, copy the server side php.ini OR create a new one under the public_html directory of the domain (OR in the directory where you want to enable allow_url_fopen) i.e.

# cp /usr/local/lib/php.ini /home/<username>/public_html/

and edit the new php.ini to enable allow_url_fopen directive:

allow_url_fopen = On

Save the file and this is it.

BTW, replace “<username>” with the actual username of the domain wherever stated above.

By default, cPanel allows one IP per account, however, in case you wish to assign multiple IPs to an account, say for a sub-domain, you can do so by editing a few files. Follow the below steps:

1) The main configuration file of a domain is stored under the /var/cpanel/userdata/<username>/ directory, so edit the subdomain related file under it

# vi /var/cpanel/userdata/<username>/subdomain.domain.tld

Change the value of “IP” to a dedicated IP and save the file. The add-on and Park domains have their related subdomain files in the same directory.

2) Now, rebuild the Apache configuration for the changes to take affect in the respective VirtualHost entry

# /scripts/rebuildhttpdconf 

3) Restart the Apache webserver

# service httpd restart

4) Add the dedicated IP and sub-domain in the /etc/domainips file to mark the dedicated IP as assigned so WHM won’t be able to assign it to other domains.

dedicatedIP: subdomain.domain.tld

Save the file and rebuild the IP pool

# /scripts/rebuildippool

5) Now, edit the DNS zone file of the main domain (i.e. the domain under which the sub-domain is created) and add an ‘A’ record for the sub-domain to point to the new IP.

# vi /var/named/domain.tld.db

Save the file and restart the ‘named’ service

# service named restart

Allow sometime for the new IP to propagate.

Note: Rebuilding the IP pool will still list the IP as free under the WHM -> IP Function -> ‘Show IP Address Usage’, however WHM wont allow you to assign that IP to another domain.
