这篇文章很好，先看完了就摘录过来！原文题目叫做How do I enable SSL after I have installed Zen Cart? 大意是安装好zen cart 后需要做的工作使zen cart 能正常运行。否则admin后台也许都无法登陆。
文章正文：
1. Make sure SSL is working on your account first
FIRST, make sure you’ve got SSL enabled on your hosting account. Work with your hosting company to get a certificate installed and to purchase one if necessary.
Can you get to “https://www.your_site.com” ? If not, ask your hosting company how to do it. If you can’t access your site using an HTTPS:// address, don’t try to enable SSL in Zen Cart or you’ll just end up with broken pages in your store!!!（这个文章是摘自一个主机商的，不过我们自己的话是要安装好apache+php+mysql+curl+ssl等配置后就可以完成这一步）
2. Enable SSL support in Zen Cart（使zen cart 支持ssl安全连接）
Once you’ve had your hosting company install your SSL certificate, and you have confirmed that going to “https://your_site.com” actually works without an error, you can turn on SSL support in Zen Cart using the following information:
Different servers may have slightly different setups and the configuration also depends on whether you have your own certificate or are using a shared certificate. We will give some examples of the most common combinations. You will need to make changes in both the includes/ configure.php and admin/ includes/ configure.php. You may have to load the whole catalog into an HTTPS directory also. Please consult your host for the URL you will need.
3、Your Own Certificate
Change includes/configure.php and admin/includes/configure.php to:
// Define the webserver and path parameters
define(‘HTTP_SERVER’, ‘http://www.YOUR_SHOP.com’);
define(‘HTTPS_SERVER’, ‘https://www.YOUR_SHOP.com’);
define(‘ENABLE_SSL’, ‘true’);
Shared Certificate
Change includes/configure.php and admin/includes/configure.php to:
// Define the webserver and path parameters
define(‘HTTP_SERVER’, ‘http://www.YOUR_SHOP.com’);
define(‘HTTPS_SERVER’, ‘https://YOUR_SHOP.YOUR_SECURE_SERVER.net’);
define(‘ENABLE_SSL’, ‘true’);
or:
// Define the webserver and path parameters
define(‘HTTP_SERVER’, ‘http://www.YOUR_SHOP.com’);
define(‘HTTPS_SERVER’, ‘https://YOUR_SECURE_SERVER.net/YOUR_USERNAME’);
define(‘ENABLE_SSL’, ‘true’);
or:
// Define the webserver and path parameters
define(‘HTTP_SERVER’, ‘http://www.YOUR_SHOP.com’);
define(‘HTTPS_SERVER’, ‘https://YOUR_SECURE_SERVER.net/~YOUR_USERNAME’);
define(‘ENABLE_SSL’, ‘true’);
NOTE: As of v1.3.x, the Admin area can only secure the “login” page via SSL unless you set the HTTP_SERVER in your “admin/includes/configure.php” to an SSL URL, in which case the entire admin area will be treated as SSL rather than only selected relevant pages. This will be changing during the admin-rewrite phase scheduled for completion sometime after Zen Cart v2.0 is released.
