Announcing Site Expansions for WordPress Hosting

We listened to your feedback about our WordPress packages. Some of you need just one more site installation so that you can do testing, or are running multiple small, resource-light sites. For cases like these, we're happy to offer our new Site Expansion.

How it works

Each WordPress account is able to add one Site Expansion. For WP Enthusiast accounts, this gets you two more installations. For WP Professional installations, this gets you five more installations. To add an expasnion, just visit the Add Ons menu in the ACC.

For performance reasons, we decided to limit each account to one expansion. That's because the expansion increases the number of your installations, but doesn't adjust your other resources (RAM, disk space, etc.). This is great if you just need another site or have a handful of small sites.

If you need more resources

If you not only need more installations, but need more server resources, your best bet is to upgrade your account type. We've made this easy -- you can change account types right in the ACC.

Tutorial: Installing a Minecraft Server on Ubuntu pairCloud

The pairCloud Server

First things first: you'll need a pairCloud server running Ubuntu, and a public IP address for the server. The size of the server you need will depend on how many players you expect to have, and whether your server will be running any other resource intensive applications. It's easy to change flavors using Live Snapshots.

Getting Ready to Install the Minecraft Server

Minecraft requires Java to run. There are several sources for Java for Ubuntu and several ways to get it, but we're going to use apt-get.

We'll start by making sure that apt-get is up to date, even if your server was just created:

sudo apt-get update

Now we'll use apt-get to install Java, as follows:

sudo apt-get install openjdk-7-jdk

We're installing Openjdk 7 because, at the time of this writing, it is available via apt-get, while Openjdk 8 needs to be compiled manually.

Optional: Create a User to Run Minecraft

It's advisable not to run your Minecraft Server as root, so you may want to create a user that will be in charge of the Minecraft files and running the server, as follows:

sudo adduser mcadmin -c "Minecraft Server admin"

Optional: Install GNU Screen

GNU Screen can be used to maintain a shell session even if you get disconnected. This use for Screen may come in handy if you're going to have your Minecraft server running around the clock.

We can install Screen as follows:

apt-get install screen

We've got a Knowledge Base article on Screen if you'd like to know more:

GNU Screen

Installing Minecraft

Let's create a dedicated directory for Minecraft. If you're logged in as the user that you want to run the Minecraft files, navigate to where you want the directory to be, and enter:

mkdir minecraft

You can change the permissions for this directory if necessary (depending on who will need to access your server) by using the chmod command. Learn more about UNIX permissions here:


Navigate to your new Minecraft directory. Next we'll need to download the Minecraft server JAR file using either wget or curl, as follows:

wget http://minecraft.net/download/minecraft_server.jar

Launching the Server

When you're ready to start your Minecraft server, you'll need to enter the following:

java minecraft_server.jar nogui

If you installed Screen, and would like to run Minecraft in a Screen session, just enter this before launching your server:

screen -S "minecraft"

This will start a Screen session with the nickname "minecraft". When you need to leave Screen to do something else, enter:

^a d

When you need to get back to your Screen session, type:

screen -r

That's it! The rest is up to you and how you want to run your Minecraft server. While many of us around here are Minecraft enthusiasts, we think the Minecraft Wiki does a great job of explaining Minecraft server administration:


Here's some additional relevant reading from our Knowledge Base:


Tutorial: Making an XML Sitemap for Your WordPress Site

A sitemap is a file that describes the layout of your site including all categories, pages and posts. It includes data such as the last time the page was changed. This file is used by search engines to help them navigate and process pages on your site.

There are a number of plugins that can handle creating the sitemap.xml file for you. However there is one that is regularly updated and gets good ratings: Google Sitemap Generator.

Log in to your WordPress Admin panel and click on "Plugins". Click on the "Add New" button and search for "Google XML Sitemaps". You'll want the one that is by the author Arne Brachhold. You can also download the plug directly:


Once you have installed it, click "Activate" then configure it for your site.

Configuring the plugin

Once the plugin is active, hover over the Settings menu and click on XML Sitemap.

On this page there are a number of options that you can change to suite your site. Most of the defaults are good for a new site, however you might want to change the post priority.

If your site is going to be a social site where you expect comments and conversations the best setting for this is comment count. This raises the priority of highly active posts.

However if your site is a business site or a normal blog with few comments then select the "Do not use automatic priority" option. All posts will have the same priority as set in the general configuration.
