Here is a quick step by step on how to set up a WordPress blog running on Nginx, PHP/FastCGI and MySQL on a low end box. Let’s assume that you are going to set up a blog on hostname “blog.example.com“.Bootstraping WordPress/Nginx/PHP/MySQL on a Cheap VPS with lowendscript

1. Make sure it is either a Debian or a Ubuntu distro though.

   Memory Usage: 43.2MB

I have to say that it is still “work in progress”, but if you want to figure out the internals please check the source code of that bash script.

2. Go and buy a cheap VPS. Yes, you know where to find cheap virtual servers under $7/month, don’t you? I am using my 6 pound/year RackVM VPS with 128MB memory to test this script, and the performance turns out to be quite good. YMMV.

   # wget http://github.com/lowendbox/lowendscript/raw/master/setup-debian.sh
   ...
   # bash setup-debian.sh system
   ...
   # bash setup-debian.sh exim4
   ...
   # bash setup-debian.sh nginx
   ...
   # bash setup-debian.sh mysql
   ...
   # bash setup-debian.sh php
   ...
   # bash setup-debian.sh wordpress blog.example.com
   ...

3. Now altering your DNS entry to point blog.example.com to your new VPS (or alter your local /etc/hosts entry). Navigate to it from your browser, and you should be presented with WordPress set up page. Fill in your blog’s name, admin’s password and contact email, and your new WordPress is online!

   Just repeat the last step (running bash setup-debian.sh wordpress <hostname>) to set up more blogs on the same box.

The lowendscript is also

Software Stack

Memory Usage: 59.6MB Bootstraping WordPress/Nginx/PHP/MySQL on a Cheap VPS with lowendscript

• dropbear to replace openssh. Invoked from xinetd.
• inetutils-syslogd to replace rsyslog.
• exim4 to replace sendmail (if installed). Re-configured to allow Internet delivery.
• cron
• nginx
• mysql. Re-configured to remove innodb support, remove query cache and reduce key buffer size.
• php with built-in FastCGI interface. Running only 1 child process and respawn after 5,000 requests.

After gaining root access to your VPS,

• Removing some commonly bundled applications that should not be there in the first place for a minimal distro (apache2, sendmail, bind9, samba, nscd, etc).
• MySQL root is given a new password (which can be found in ~root/.my.cnf)
• Installing each WordPress site under /var/www/<hostname>. It will create appropriate database, users and password for the site.

It’s pretty similar to my own stack that runs LowEndBox.com.

Memory Usage

I am testing the same script on the following 3 systems:

• Ubuntu 10.04 64bit (RackVM)
• Debian 5 64bit (RackVM)
• Debian 5 32bit (VPSGuy)

They are all showing different memory usage. I am taking the snapshot of memory usage AFTER 10 page loads on the WordPress blog that has been created to ensure PHP process is fully loaded.

Here are some of the benefits that come along with VPS hosting:The Benefits of VPS Hosting

Multiple Domain Hosting: Although shared hosts offer multiple domain hosting, most of them do not provide enough resources for you to do so and still enjoy a smooth performance.   Many VPS providers offer plans that allow you to host multiple websites without suffering performance issues.  In most cases, you can set up separate email accounts and allocate specific resources for each individual site.

Performance - Having your own allotment of resources allows you and your visitors to enjoy faster load times.

Managed Data Backups: As with any hosting solution, a VPS plan should offer a way to backup your data.  Because anything could occur within the provider’s network, it is recommended that you choose a service that allows you to manually backup your own data to assure that it can be restored at any time.

Stability: Unlike shared hosting, the traffic and activities of other VPS customers will not adversely affect your operation.

Server Monitoring: A good VPS provider will actively monitor its network and hardware your account relies on.  This ensures the physical security of the server and also helps defend against virtual threats such as hackers, malicious software and DDoS attacks.

Management and Support: Similar to a dedicated hosting account, VPS hosting calls for you to manage your own server .  However, there are many companies that provide support and management services to assist with administrative tasks.  This feature is invaluable if you lack technical savvy.

VPS Features

The features and services of VPS hosting vary depending on the provider.  Although the ones you will need all depends on personal requirements, here are a few you may want to look out for:

Dedicated Resources - VPS hosting provides you with more disk space, CPU and RAM.The Benefits of VPS Hosting

VPS hosting offers an inexpensive way to get many of the features, resources, control and flexibility of a more costly and complex dedicated server.  With the technology increasing in popular, prices are dropping rapidly, assuring that you can find a reliable VPS solution that meets your hosting needs.

Root Access: Root access will grant you with complete control over your VPS account from configurations to software installations.  All of the actions can be handled from the interface of your control panel application.

Flexibility - You have the freedom to choose the operating system and software you want to install on the server.

Seemingly out of nowhere, VPS has become the preferred hosting solution for small to medium sized businesses.  VPS stands for Virtual Private Server, a solution that effectively bridges the gap between the limitations of shared hosting and the flexibility of dedicated server hosting.  A VPS is created by virtualization software which partitions a single physical server to form multiple servers within it.  Each virtual server is completely independent of its neighbors and functions like an actual networked server.  What makes VPS hosting so popular is that it provides control at a level similar to a dedicated server at a price not to far removed from affordable shared hosting .

Article Source : The Benefits of VPS Hosting

Another concern is a drawback to remind you that VPS hosting is still a grade below the power of a dedicated server. While you have a guaranteed allotment of system resources, you are still required to share hardware assets with other VPS users hosting on the physical server. For this reason, a virtual private server cannot achieve the stability and optimal performance of the dedicated variety.What is a Virtual Private Server Hosting?

• Enhanced Protection – A virtual private server can ensure far better security than what is provided on a shared hosting platform. With the server running in the comfort of its own isolated environment, you are shielded from the stability and security issues originated by other users. Though a dedicated server offers the best performance and security, VPS hosting is not too far behind.

Virtual private servers are designed to provide customers with a way to save money without the sacrifice of performance, flexibility and security. VPS hosting can be viewed as the perfect compromise between a shared and dedicated server, as it provides a great deal of freedom at what is usually a very reasonable price.

Do You Need a Virtual Private Server?

How You Can You Benefit from VPS Hosting

• Incredible Value – A VPS hosting solution can provide you with a tremendous value. While a dedicated server could end up costing you well over $100 per month, the price of a virtualized platform is usually not too far removed from shared hosting. The distinct makeup of VPS technology allows the cost of the hardware, software, network connectivity and maintenance to be efficiently distributed without compromising your quality. What is a Virtual Private Server Hosting?

A VPS hosting plan can be the solution to all of your needs. However, due to the technical aspects and minor drawbacks involved, you need to give this option careful consideration before making a final decision. The best way to decide would be to access your needs and current hosting predicament. If your website is thriving on a shared server, then virtualization is probably a technology you could do without. However, if you find that this environment can no longer deliver the performance and level of security you require, VPS hosting could be the next step towards expanding on your web presence.

Here are more specific details on how you can benefit from a virtual private server:

• Guaranteed Power – Another major plus of VPS hosting is that it provides you with guaranteed system resources. Unlike in a shared hosting environment, you do not have to compete for most resources and have the luxury to receive accurately measured allotments that fit your specific needs. This, in turn, provides you with a robust, scalable solution that gives your business the room it needs to grow.

Virtual private server, or VPS, represents the next generation of web hosting that revolves around partitioning a single computer to simulate multiple servers. The unique aspect is that each server has the look and feel of a physical server, equipped with its own operating system and the ability to be rebooted independently of others. Similar practices have actually been used in mainframe computers for some time, but the emergence of virtualization technology has pushed VPS hosting into the mainstream market as a cost efficient, high performance solution.

VPS hosting offers many advantages over its shared counterpart, but there are some disadvantages that warrant your attention. First and foremost, you should know that this solution is very much like a dedicated server in the way it requires you to actively maintain the server. This usually includes applying security patches and system updates, which could possibly take your time and focus away from other critical aspects of the business. When problems arise in your virtual environment, it is your responsibility to resolve them via remote administration.

• Freedom and Flexibility – What makes VPS hosting so comparable to a dedicated server is the control and flexibility it grants to you. In most arrangements, you have the option of utilizing various provided add-on scripts or installing your own custom applications. This is enabled by root access that allows you to interact deeply with the server. In terms of customization, you are generally allowed to create applications in whatever programming technologies installed on the server, be it PHP, ASP or Cold Fusion.

Before you move on, there is still one last thing you should know – Do you need a VPS hosting? This, question, unfortunately, can be only answered by you. You’ll have to justify if a VPS hosting is necessary (or sufficient) for your website. What’s your 12 months plan for the website? How busy do you estimate your website will be? What are the custom applications to be installed? These are some of the must-ask questions and prevent yourself from overspending.Ultimate Guide for VPS Hosting Shoppers

There are tens of thousands of VPS hosting providers out there and I am sure many of them provide quality services. A quick Google search should get you hundreds of VPS hosting reviews and ratings and don’t worry, I am not going to confuse you further with another table or comparison chart.

1. VPS Hosting Pricing

What’s good about VPS hosting?

What is VPS hosting?

Generally for starter, a VPS plan with 512 MB RAM plus a burstable RAM of 1 GB should be more than enough.

Money is always the main factor when we are purchasing something. When comparing the price of VPS hosting, do not aim for the cheapest deal, go with those with a reasonable price tag instead. The reason behind this is because we do not want our host to run on a thin profit margin. Yes I know it sounds crazy but it’s true. Think about it – we want stability when it comes to web hosting and shifting web host is certainly the last thing we want to do after settling down. A hosting company running on a thin profit margin is simply… instable (the risk of going out of business due to deficit accounts).

A Virtual Private Server (VPS) is like a server in a bigger server. I know the statment is a little confusing but please don’t get panic about it.

There, I have put down all the important points about VPS hosting and I hope it helps you to understand and to choose your right web hosting.

What to look for when shopping for a VPS hosting?

Do not go with VPS provider that has limited sets of hosting plans. As mentioned, VPS hosting is unlike shared hosting – where most of the operations are similar. Before purchase, you should check if the web host allows you to customize your VPS hosting plans.

Advantages of VPS over shared hosting

Advantage of VPS over dedicated hosting

So again, if you are serious with your website, go for those with a reasonable pricing but not the cheapest.

Here’s rough idea on how much RAM you need. In brief, for a single website operation, you need at least 512 MB of RAM in order to run cPanel and Plesk on your VPS. Though cPanel states that it only needs 256 MB but as it is with other applications, 512 MB will ensure everything runs smooth. In case you are operating multiple websites on a single VPS, higher RAM is a must. Expect to go up to 2 GB if your websites are heavy trafficked.

2. Server Memory Capacity (RAM)

For example, if you need 500 MB disk space and 5 GB monthly data transfer (something relative small), and 512 fixed RAM – it really makes no sense to sign up for a 80 GB disk space, 1000 GB monthly data transfer, and 512 fixed RAM for $74.95/mo. I mean, why settle with high server specs that you will never use when all you need is some extra memory capacity?

In my opinion, memory capacity (RAM) is the most important features in a VPS hosting. In fact, how well (or bad) your VPS hosting performs depends greatly on how much RAM you have on hand. The memory capacity simply influences everything in your virtual server – from server efficiency to speeds, and to power consumption. It’s so important that in many cases, RAM allocation actually serves as price determiner of the entire VPS hosting package.

Basically there are five main consideration points when choosing the right VPS hosting, namely – pricing, RAM allocation, customer supports, control panel, and hosting plan flexibility. I’ll get into the details one-by-one.

5. Flexibility

The actual concept behind VPS is very simple – basically what VPS hosting providers do is to split a server into multiple smaller size individual servers (using virtualization technology) and rent it out to different customers. Each of these virtual servers looks and feels the same like a dedicated server except for one thing – they share the same hardware with one another.

However in case you are looking for some recommendation, I’ll refer you to Hostgator.

When compare with dedicated hosting, VPS has only one advantage – it’s cheaper. In fact, it’s much, much cheaper. In many cases, while the features are more or less the same, a VPS hosting is 30-40% cheaper than a dedicated hosting deal.

Another pro of VPS compare to shared hosting is flexibility. With VPS hosting, you will get access to the system root. This means you are free to install any custom software or to tweak your system files in order to fulfill your website needs.

For example, table above shows the price different between dedicated and VPS hosting.

Why Hostgator VPS hosting?

VPS hosting plan: My recommendation

A user-friendly control panel as it makes day to day server management easier – tasks such as adding domains, debugging, and setting up email accounts.

What’s best about VPS is the isolated hosting environment that secures your website’s performance and safety. As mentioned, a VPS-hosted website will operates independently like a dedicated server – you do not share disk space, RAM, processes, TCP/IP stacks, operating system, or whatsoever. What’s going on with your neighbors (other private servers that run on the same machine), either it’s overloaded with heavy traffics or severely hacked, will not affect your website’s performance.

VPS providers will normally offer you several options of control panels where the normal ones are either Plesk or WHM/cPanel. These control panels offers similar functionality where they enable you to edit files in the server for a web interface rather than manually and both are equally good.

With that, I’ll end this article and good luck if you are shopping for the new VPS hosting!Ultimate Guide for VPS Hosting Shoppers

• Topnotch hosting services Based on my extremely good experience with their other hosting services – shared and dedicated hosting (see my Hostgator review).
• High Flexibility Hostgator VPS hosting plans are very flexible – 9 pre-set plans, managed/unmanaged options, different pre-installed operating systems, optional IP addresses, wide in house software supports, etc etc.
• Stability Hostgator is one of the fastest growing companies in United States (Won Inc. 5000 Fastest Growing Companies Awards for a couple times).
• Room to expand As you might already knew, Hostgator also provides reseller and dedicated hosting plans – this gives room to expand when your website grows.
• Eco-friendly Last but not least, Hostgator is green. This means all servers are powered with recyclable clean energy.

You should always communicate with the web host before making any purchase (especially when you are new). It’s not about checking which web host provides the fastest response; it’s about getting to know the people working inside the hosting company and check if you are comfortable to deal with the support staffs.

Final words about VPS hosting

There are a couple of reasons why Hostgator has been one of my top picks for years. In quick, here’s why I think Hostgator’s VPS hosting is a must-see.

From a customer’s perceptive, a VPS hosting is the perfect stepping stone between shared and dedicated web hosting. When shared web hosting is no longer sufficient and you are not ready to go with dedicated – VPS hosting is your answer.

See, VPS hosting is unlike shared hosting where 90% of the operations are standard case. In VPS hosting, most of the things are ‘non-standard’ thus a technical support department that really care about their customers (and with the right knowledge) is extremely important.

Another term you should take heed of is the ‘Burstable RAM’, or in certain cases, the backup RAM. Burstable RAM is the temporary backup resources over your standard memory quota. Burstable RAM is extremely important to protect your website from sudden traffic-surge (for instance, a Digg- or Stumble-effect).

This need your DNS support for AAAA records, which is IPv6 records. Now basically all of the domain registrar’s DNS support, if not support, you can use dnspod the service is free, and support for AAAA records.

Although your VPS does not support IPv6, but we can through the IPv6 Tunnel to solve, which is usually said, IPv6 Over IPv4, can be interpreted as the IPv6 in IPv4 to establish a small pipeline. We use the HE (Hurricane Electronics) provides a free IPv6 Tunnel Broker, HE has the world’s largest IPv6 backbone network in the world, are provided with IPv6 Tunnel Broker service.

A virtual private server (VPS, also referred to as Virtual Dedicated Server or VDS) is a method of splitting a server. Each virtual server can run its own full-fledged operating system, and each server can be independently rebooted.(Via Wikipedia)What is VPS?

Benefits of VPS

(Via webhostingsecretrevealed.com)

Affordable VPS is cheap. You’ll get features like dedicated servers but cost a lot more cheaper (in most of the case, 50% less) than a dedicated hosting plan. You can compare the pricing different between a dedicated server and VPS hosting below.

When your website has outgrown your shared hosting plan and you couldn’t afford the price of a dedicated server, then VPS is your answer. Most webmasters see VPS as the stepping stone to dedicated or self-managed private server.

Also, getting a flexible VPS provider that allows hardware customization is very important. Avoid web hosts who offer only ’standard’ plans as this will creates troubles in your future upgrades. Each website has different needs, maybe you need lower CPU speeds, or larger storage, or less bandwidth, or more RAM – you’ll never know what kind of upgrades you need in the future. Do you want to upgrade your entire hosting plan everytime you need a minor upgrades? No, of course. If all you need is just some extra RAM, why should you upgrade the entire hosting plan and pay for all the unnecessary storage and bandwidth?

What to look for when choosing a VPS?

Isolation Each private server has its unique file system and gets a  guaranteed fraction of the server’s disk space, CPU power, bandwidth, and memory. Hence, a website hosted on a VPS runs on an isolated environment where its performance will not be affected by other websites. Also, a VPS does not share web application and services with other websites thus it eliminates the risk of downtime or hacks due to other’s mistakes.What is VPS?

The best things about VPS are its dedicated-server-alike features and affordable pricing.

Is VPS right for you?

Customization VPS users get full root access. This allows server customization – you get to install your own software/application and manage your server as you would on a dedicated server.

Besides pricing, there are a few other important points that you should look at when it comes to VPS shopping. Choosing a VPS provider that’s easy to communicate is very important. A web host who’s willing to listen and accommodate your specific needs is very important.
