You must fully meet the system requirements for efficient and flawless operation. Make sure
you find current versions of PHP and MySQL as well as product requirements. All system
requirements are as follows:
• Windows or Linux OS,
• PHP Version 5.x or higher,
• MySQL Version 4.1.x or higher,
• Curl support with SSL,
• GD image library,
• IonCube loaders.
Take these in detail.
Windows or Linux OS
PHP Version 5.x or higher
The version of PHP you are using must be 5 or higher. If not available, please visit
http://www.php.net.
MySQL Version 4.1.x or higher You must use MySQL version 4.1.x or higher, which is essential
for PHP.
If not available, you can browse this address: http://www.mysql.com. Suppose that the name
of the site where you will install WHMCS with SSL is http://www.whmcskitap.com. For this
site name, we must first purchase a specific IP address for our site name. Then we will buy
SSL Certificate and secure our IP address as "https" (Secure Hypertext Transfer Protocol). I
recommend using RapidSSL because it is economical and trouble-free. For RapidSSL you can
check out http://www.rapidssl.com. The installation of the SSL Certificate will be provided
by the place where you purchased the service.
GD Image Library
The server's image handlers. The server without GD support is almost non-existent.
