We have written previously about regularly backing up Storm Servers, but that only covers automated image backups. With the Storm platform, it is possible to take image snapshots of your server whenever you wish.
While Liquid Web Linux servers always have either APF or CSF firewalls installed, Storm servers can also have an external firewall put in front of them, at no additional charge. A Storm firewall provides an extra layer of protection on an already secure server. Here’s how to set one up:
Liquid Web’s Account Management System has a robust API that allows for accessing your account from outside of the Manage interface, such as with the Storm WHMCS plugin. In order to access the API, an API user must be created for that account first. Creating an API user is an easy and straightforward process.
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.]
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.
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.
Select ‘Use Parcels’, other options for parcels, and ‘Matched release for this Cloudera Manager server’
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.
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.
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.

So you have come to the realization that you need an SSL Certificate. But there are several different types. Which one do you really need?
If you have ever set up a Storm server in the past, you have probably seen how much easier it is to get a new server up and running than a traditional server. Once the server itself is up, of course, there is still plenty of work to do getting other pieces configured: installing an application, setting up specific database configurations, and so forth. Tools such as Puppet and Chef help you to automate this process… but you still have to log in to your manage account and order new servers to begin with.
At least, you did. With the Storm API, you can automate nearly all aspects of administering your Storm servers.
If you need to review your invoices or print them for your own record keeping you can do so very easily by logging in to https://manage.liquidweb.com.
So your business has grown, and you need to increase your number of servers to two or more. Now is the time to decide on a hostname scheme for multiple servers. Picking a hostname scheme that works for your endeavor pays dividends down the road in terms of keeping your setup organized. While the topic may seem trivial, the wrong hostname scheme can make your day to day work needlessly complex.
As important as DNS is to web hosting, it is a good idea to make it redundant when possible. If you have two or more cPanel servers, you can use cPanel’s DNS clustering to lower the risk of a DNS failure on a nameserver taking down all of your sites. Here’s how to set that up:

Changing an existing domain name and the associated account on your server is a task that most users don’t think about until it becomes necessary. Thankfully the tools provided by cPanel make this relatively easy.
