Nginx configuration in Proxy mode with SSL

In this article we list steps of basic Nginx configuration, in PROXY mode, with SSL. Nginx works as SSL terminator and proxies all requests to Apache port 80. In this recommended mode SSL certificate has to be installed in advance via cPanel SSL function.

To configure Nginx in non-SSL Proxy mode, refer to this article.

In order to improve web site loading speeds for our shared cPanel customers, RedyHost implemented high performance stack using Nginx. 

Nginx works in two different modes, allowing to proxy requests to Apache (and cache static files) or to serve PHP scripts directly, bypassing slower Apache web server completely. In both cases Nginx supports Google's famous mod_pagespeed module, allowing to compress and minify web page size. mod_pagespeed is configured in core filters mode to avoid compatibility issues with different CMS and website types. Core filters proven to work great for 99.99% of use cases, reducing page size and number of connections for up to 3x times.

Note! For compatibility and security reasons RedyHost recommends to run Nginx in Proxy mode.

By default, for all new accounts, Nginx is configured in Proxy mode.

To access Nginx configuration

- login to cPanel and click Nginx link

Nginx plugin for cPanel

Configuring a domain in Nginx Proxy mode with SSL

In such configuration we recommend that you disable any SSL redirection functions in Apache. Apache will listen on port 80 and no SSL functions or redirects should be enabled in Apache, .htaccess file or in plugins of your website.

Drupal specific instructions

If you run Drupal, we recommend to disable securepages module. For Drupal 7, add the following to your settings.php file

$conf["https"] = TRUE;

$base_url = "https://[your-website-full-url]"; // Do not add / at the end.

If you have redirection to www. in your .htaccess file, make sure the $base_url variable includes www. in the URL of your website.
