How To Set Up WP Super Cache With Template

Templates are an easy way to set up OpenLiteSpeed for various uses. In the following article we will guide you through the steps to set up virtual hosts running WP Super Cache, a powerful caching plugin that should increase the ability of the your WordPress site to handle gobs of visitors. The first part of this article will cover importing the template. After the template is imported, you just need to create virtual hosts for each domain you want to run with WP Super Cache and install WordPress and WP Super Cache in those virtual hosts.

Note: Any setting not specifically noted in this walkthrough can be left as the default.

Import the WP Super Cache template

1. Download the WP Super Cache template file.

2. Save the template file to /usr/local/lsws/conf/templates/wpsupercache.xml.

3. Make sure user lsadm has write permission.

chown lsadm /usr/local/lsws/conf/templates/wpsupercache.xml

4. Add the template on the WebAdmin console.

WebAdmin console > Configuration > Virtual Host Templates > Add
Template Name: wpsupercache (name it anything as long as it does not conflict with existing templates)
Template File: $SERVER_ROOT/conf/templates/wpsupercache.xml
Mapped Listeners: Default
Note: In order for the server to direct traffic to the proper vhost, you must have listeners set up to listen on the proper IP and port. When you use a virtual host template, you do not have to define listener-to-virtual host mappings in the listener settings. Instead you set the mapped listeners when adding a template. In the above settings, we have used the listener "Default", which is set up to listen on port 8088 of "ANY" IP by default. You must adjust your listener settings to make sure there are listeners on the IP and ports you need. (The easiest way to do this is for most sites to just change the port setting to "80" for the Default listener in WebAdmin console > Configuration > Listeners > Default > General. This gives you a listener listening on port 80 of all IPs.)

5. Graceful restart to apply changes. (Actions > Graceful Restart)

Set up virtual hosts using this template

1. Create a member virtual host from the template.

WebAdmin console > Configuration > Virtual Host Templates > wpsupercache > Member Virtual Hosts > Add
Virtual Host Name: super1
Note: We have named our WP Super Cache vhost "super1". You can name it whatever you want, but remember to then replace any instances of "super1" in this tutorial with the name of your virtual host.

2. Create directories for this vhost.

As the root user, run the following commands:
mkdir /usr/local/lsws/super1
mkdir /usr/local/lsws/super1/{html,logs,conf}
chown lsadm:lsadm /usr/local/lsws/super1/conf

3. Graceful restart to apply changes. (Actions > Graceful Restart)

Your new vhost is now live and ready for WordPress and WP Super Cache. All you have to do is install them.

Install WordPress

1. Install PHP.

The easiest way to install PHP for OpenLiteSpeed is through our CentOS repository. If the LiteSpeed Repository was not installed and enabled during the web server installation, follow this guide to install and enable the LiteSpeed Repository.

Use the following command to install PHP with the modules required:

yum install lsphp55 lsphp55-common lsphp55-gd lsphp55-process lsphp55-mbstring lsphp55-mysql
Note: There are four versions of LSPHP (lsphp53, lsphp54, lsphp55, lsphp56) available.

Direct LSWS to the location of the installed PHP. (In this example, PHP 5.5 is installed by default in /usr/local/lsws/lsphp55/bin/lsphp. Change the value of the WebAdmin console > External App > your external application > Command setting to reflect that.)

If you are not using RedHat or CentOS, or you prefer to build PHP by yourself, see our instructions for building PHP for WordPress here.

3. Download WordPress into your virtual host document root: /usr/local/lsws/super1/html

cd /usr/local/lsws/super1/html

4. Grant the web server user write permission for WordPress WP Super Cache installation.

chown -R nobody wordpress

5. Set up a MySQL database and user for WordPress.

First, install MySQL:
yum install mysql mysql-server
Instructions for setting up the database can be found at

6. Graceful restart to apply changes. (Actions > Graceful Restart)

7. Point your browser to http://server_ip:8088/wordpress/wp-admin/install.php to run the WordPress installer.

Install and configure WP Super Cache

1. In the WordPress dashboard, go to Plugins > Add New. Search for WP Super Cache and install it.

2. Once WP Super Cache is installed, go to the plugin admin page (Settings > WP Super Cache), and configure it as follows:

Easy Caching: Caching On
Advanced Caching: Cache hits to this website for quick access
                  Use mod_rewrite to serve cache files.
                  Compress pages so they're served more quickly to visitors.
                  Don't cache pages for known users.
                  Don’t cache pages with GET parameters. (?x=y at the end of a url)
                  Make known users anonymous so they’re served supercached static files.
                  Cache rebuild. Serve a supercache file to anonymous users while a new file is being generated.

3. If a page is served from supercache it will have a signature at the end of response page similar to the one below: (This signature is only visible when viewing the source.)

<!-- Dynamic page generated in 1.187 seconds. -->
<!-- Cached page generated by WP-Super-Cache on 2013-05-31 00:02:57 -->

<!-- Compression = gzip -->
