Create a Tor Relay on CentOS 6
Filed under: Technical Support

This guide will walk you through the basic installation and configuration of a Tor non-exit relay. Running a relay helps strengthen the Tor network by making it faster. You should not run a Tor Relay on a server that has important sites or databases on it. By running a relay you are essentially donating bandwidth to the Tor network. It would be wise to keep this in mind and avoid causing yourself potential bandwidth overages. This guide does not cover how to actually connect and use the Tor network as an end-user.

“Tor (originally short for The Onion Router) is free software for enabling online anonymity. Tor directs Internet traffic through a free, worldwide volunteer network consisting of thousands of relays to conceal a user’s location or usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult to trace Internet activity, including “visits to Web sites, online posts, instant messages and other communication forms”, back to the user and is intended to protect users’ personal privacy, freedom, and ability to conduct confidential business by keeping their internet activities from being monitored.” – “Tor (anonymity network)“.

Installing the WHMCS Plugin for Reseller Accounts
Filed under: Technical Support

Installation of the WHMCS  Plugin that is being made available for the participants in the Liquid Web Reseller Hosting Program is a rather straightforward process. The following steps will go through how to do this. This article will go over the steps required to install and setup the plugin. If you are not comfortable with this process, please feel free to contract Heroic Support.

  • Create an API user in the Liquid Web, or Storm on Demand management interface. Be sure to create a user that has a unique and strong password. This should be different from any other passwords that you use for your account.
  • Download the plugin zip file in your root WHMCS directory. The directory might not be the same for everyone, but an example of how to do this would be:

Via SSH on the server:

cd /home/$WHMCSUSER/public_html/WHMCS/
wget http://media.liquidweb.com/WHMCS/StormOnDemand_v6.zip
unzip StormOnDemand_v6.zip

You can also use FTP to upload the file, or use the cPanel File Manager if you wish. Regardless of the upload method you will need to unzip the file using the command from above.

  •  Activate the Storm Billing plugin in the admin section of WHMCS
  1. Click on the Setup tab near the top of the page
  2. Select the “Addon Modules” option
  3. Once the list has loaded, find the “Storm Billing” addon and click “activate”
  4. To give this module the correct permissions,click on the “configure” button and then select “Full Administrator” in the “Access Control” section and then click ” Save Changes”

At this point, you should be able to start setting up packages and products within WHMCS.

How to Install Hadoop with Cloudera
Filed under: Featured Articles

We recently illustrated how some of our customers were using Liquid Web’s extensive resources to leverage big data with Hadoop. While many users could benefit from the data management capabilities Hadoop delivers, finding the right software to launch it and installing Hadoop stacks may give some pause. Using Cloudera, this can be accomplished in just a few simple steps we’ll outline below. [note: There are a number of software options available to run Hadoop, however we have chosen to highlight Cloudera as it offers a great deal of simplicity, ease, and automation for those new to running Hadoop.]

Step 1:
Install Cloudera Manager. Liquid Web cannot install Cloudera on your servers for you due to Cloudera’s Terms of Service. However, this simple installation gives you access to automatic installation of Hadoop stacks, other related software stacks, and nodes (also known as Hadoop clusters) for free.

Step 2:
Choose from Cloudera’s free edition or its fully supported enterprise version if you plan on running a cluster larger than 50 nodes or if you would like additional support from Cloudera. All of the projects you launch will remain open source and can be built from source. As the free edition offers more than enough functionality and ease of use for the average user, we will proceed from here as if you have chosen this option.

Step 3:
You will now need to specify the hosts for your installation:
hadoop-cloudera-04

Step 4:
Select ‘Use Parcels’, other options for parcels, and ‘Matched release for this Cloudera Manager server’
hadoop-cloudera-05


Step 5:
Provide SSH login credentials by selecting root and allowing all hosts to accept the same password (this can be changed in the future as needed). Once this is confirmed, Cloudera will begin installing your host(s) as well as your clusters. This may take a moment depending on the amount of data you’re importing. Once it has completed, check the list of hosts it generates and make sure everything has completed with no errors. You may run this installation again or go back and check for mistakes if it did not complete properly.
hadoop-cloudera-11

Step 6:Cloudera Manager will now allow you to select which services to install. Based on your needs, you can choose anything from “Core Hadoop” services (if you are concerned with space) to “All Services” (to ensure the functionality of any future endeavor) to your own custom options.
hadoop-cloudera-12

Once you choose the services you want to install on your cluster, the automatic installation of your Hadoop stack will complete. From here you will be taken to your main Cloudera Manager menu where you can begin using Hadoop.

Administering LiteSpeed Web Server in cPanel
Filed under: Technical Support

If you are used to administering Apache on a cPanel server, administering the faster Litespeed webserver is not that much different. Litespeed transparently takes over for Apache; any configuration changes that you would normally make in an Apache configuration file or .htaccess files is still made in those files. In fact, once Litespeed is installed you can administer your cPanel server like you normally would. The few changes you would want to make to Litespeed directly can be done through your server’s Web Host Manager (WHM).
