MySQL provides cluserting but not fail over for end user. So here at JaguarPC Web Hosting labs we tested MySQL fail over cluserting. To setup MySQL clustering a minimum of 3 computers are required. However recommended number is 4 or more. And to setup a failover mysql cluster, we add one more machine making it 5. There are 3 parts in a MySQL Cluster:

Data: 2 or more nodes act as data. In MySQL 5.0, the data sits in memory, while in 5.1 data can go on disk as well (5.1 is release candidate). For our testing we use 2 data nodes. When one of the node dies, the other will serve the data.

Management: One machine is used for cluster management. Once the cluster is started and this machine goes down, the cluster can continue to work. So this is not critical for our fail over setup.

SQL:: 2 test machines were setup as SQL nodes in failover with a single “floating IP”. When one died, the “floating IP” moved to the second machine using arp spoofing. MySQL client would connect to SQL node using that floating IP, so for the client MySQL Server remains up and running when one of the SQL nodes die. This part of the setup is JaguarPC’s own making and is available through Dedicated Server Hosting offer.

The rough diagram for this whole setup is as follows:

MySQL client -> [ 2 SQL nodes fail-over ] -> [ 2 data nodes ]

RAM Requirement for Data Node: Since MySQL 5.0 uses RAM to hold the data in data nodes, you can use the following formula for obtaining a rough estimate of how much RAM is needed for each data node in the cluster:

(SizeofDatabase × NumberOfReplicas × 1.1 ) / NumberOfDataNodes

Say our database size is 10 GB, and we make 2 replicas and host it on 4 nodes, then we need about 6GB RAM in each node. If we store our 10GB with 2 replicas in 6 nodes, then we need 4GB RAM in each node. You get the idea.

More will be posted later about this topic.

Roundcube is a webmail interface which uses ajax extensively to give it a “desktop” like feel. According to a recent post on cPanel forums it is being internally tested for integrating it into cPanel. This would be a good alternative to horde which has a history of problems, and squirrelmail which looks ugly to non-geeks.

There is often some confusion about what all comes with a web hosting package. Usually the misconceptions are based on the type of support that is offered when purchasing a web hosting plan.

Web hosting providers are a lot like property or apartment managers.

Lets compare. First, I’ll start with shared hosting.

Do you remember when GeoCities first came out? In order to get a free web site, you first had to pick your neighborhood based on your site’s content. For example, if you had a site about technology, you’d choose the neighborhood silicon valley. From there you’d choose a house. Each house was assigned a number and your website URL would then be geocities.com/siliconvalley/[housenumber]. GeoCities long ago did away with that format, and web hosting has come a long way since those days but the concept of shared web hosting is mostly the same.

When you purchase a shared hosting plan, you’re essentially renting space on a web server that is shared by several other web site owners all hoping to host a web site on a budget. The server space will come fully ready for you to ‘move in to’. Essentially, the electricity will be turned on, the fridge will be present for you to store your perishables, and water will run. The property managers (web host provider) will make sure you have a clean space to move your stuff into. It is then up to you you to move your furniture in and organize it however you want.

Web hosting providers generally do not provide support for coding, scripting, development, or design. Just as apartment managers generally don’t tell you where to hang your pictures, which furniture to use or where to put your things.

What if something breaks?

“Your analogy doesn’t work. My property manager will fix the stove if it breaks.”

If something that comes with your shared hosting plan breaks, lets say cPanel in this example, we will certainly fix it for you. But we aren’t going to cook your dinner for you and neither will your property manager.

“What about all the cool programs you offer for me to install? Like Wordpress? Do you support that?”

We can host a Wordpress site and we even offer an easy way for you to install it. Wordpress is a third party product. Think of Wordpress as the refrigerator in your apartment. It may come with the apartment but your apartment managers didn’t create it. You can put whatever you want in it. But your property managers aren’t going to keep it clean for your nor throw out the food that goes bad. That’s your job. The concept is the same with hosting a Wordpress site. You need to keep it clean and updated to the latest secure version. This actually applies to any software, script, or program you install on your website.

This doesn’t mean you’re completely on your own. Your ‘property managers’ are going to keep an eye on things (servers) and make sure your ‘neighbors’ (other customers) aren’t making life miserable. Kind of like a gated community: We’ll attempt to block intruders and abusive ‘renters’ who continually have a detrimental effect on their neighbors will be asked to ‘move out’.

“What about VPS. You do everything, right?”

Purchasing a VPS hosting plan is like purchasing a condominium. It’s still shared with others, but you’ll have more control over what happens in your ‘space’. Your hosting provider will provide you with the basics, and you can purchase addons such as a control panel, extra RAM, etc, but the concept of the apartment is still the same. What you do from there with your site space is up to you. Your web hosting provider will still keep an eye on things and make sure your neighbors are all playing nice, but the space you’re renting is yours to maintain and keep up to date.

“I get it. But what about a dedicated server? Surely you’ll do anything I want?”

Not quite. When you purchase a dedicated server plan it’s like renting a house. It’s bigger than an apartment, and you have all the control to do whatever you wish with the space. You can even invite your friends over for a party! But it’s totally yours to maintain and operate on your own.

Lets say you want maid service, lawn care, and extra security. You’d pay extra for these if renting a house, right? The same holds true for dedicated web hosting. You can purchase Managed Services of different levels depending on your needs and we’ll take care of things for you. I warn you though, we don’t do windows. (Get it??) (OK. OK. I lied. You can actually add on Windows OS for just $35 more on our dedicated hosting plans.)

“I only need an apartment (shared hosting). Can I at least pay you to help me out with some things?”

Sure. We can do script installations and even upgrades of third party products if you wish. There is a fee attached, but this type of support does not come standard with a non-managed hosting account.

In a nutshell, Web Hosting and renting an apartment is pretty similar. We’ll provide you fresh clean space to work with, and we’ll keep things running smoothly. We’ll even offer a few tools and perks to keep your new place shiny and sparkly, but it’s ultimately up to you to decide what you want on your site, where you’ll put things, and how.

This morning there was a network/power problem at the Atlanta data center which affected all the JPC servers. The is resolved now. However; we’re still investigating an issue with a few servers. To get an update on this please visit http://backup.jaguarpc.com

We want to offer our sincere apologies for any inconvenience or frustration experienced as a result of this. We fully understand as we are just as concerned and at this point baffled as to how this could have happened. As of now, we do not yet have a full explanation of the nature of the issue. As soon as we get one will be sure to relay this to our customers. We will also be looking into ensuring this does not happen again.

Happy New Year! Wait.. that was so last week. Well, I hope the New Year is finding you happy and healthy so far!

Before I go any futher, I should apologize for introduce myself: My name is Tracie, one of the latest newcomers to JaguarPC Web Hosting and I’ll be taking over helping out with the JaguarPC blog. (Don’t worry… we’ve still got Connie chained to the desk around to post those awesomely interesting articles about Google, Spam, internet security, etc.)

I thought I’d start off by telling you all about my visit to the eye doctor today. (It was the kind of visit where they put a bunch of drops in your eyes that make you see double and scream, “bright light! bright light!” as soon as you step outside.)

You might be thinking, “What the heck does that got to do with web hosting?” You might also be thinking “who’s this crazy lady?” Don’t worry. You’ll get used to me.

I was called up to the counter before my appointment so they could update my records with my insurance, address, etc. and they asked me to pay my co-pay amount. I have a flex spending account through my husband’s employer that covers this. Since it’s so early in the new year I have not yet received the new account number and debit card. I asked that they bill me. She stares at me a second then says they can’t do that. I explain the situation and she doesn’t argue one bit and simply agrees to bill me. I had to explain this two more times (when I picked out my new glasses, and during checkout). At first they all told me they could not bill me. When I explained the situation, I got what I asked for.

I chuckled to myself as I walked out (that is, until the sun shone down on my extremely dilated eyeballs like the death star blasting Princess Leia’s homeworld, then I stifled a scream). All I had to do was ask, and I received what I wanted. It didn’t hurt anyone to ask and the worst case scenario is they say no.

Here at Jaguar PC, we welcome you to ask questions. We pride ourselves on offering the best possible customer support. You never know unless you ask. Need a coupon code? Ask! Need a deal? Ask! Will you always get the answer you want? Not always. But we’ll do our best and it never hurts to ask.

Today I was asked, “Are you running any specials?” Are we ever! We are almost always offering a special or a little something extra with our plans. You can find our latest deals on our web hosting forums (if you didn’t know, we have an outstanding forum community at Jaguar PC) under the thread: Web Hosting Sales, Pre-Sales, Specials and Coupons. Check it out!

That’s it for today’s installment. Check back often for tips and tricks and hopefully some minor entertainment! You can also subscribe to the JaguarPC Web Hosting Blog Feed. Now that your system administrators have blocked MySpace and Facebook at the firewall you need something to keep yourself entertained, right??

If you would like to make suggestions in regard to the knowledge base this is the place.
