For users who require high performance hosting services yet cannot opt for a dedicated server, the golden mean is VPS hosting. They can get the facility of a dedicated server in very cheap cost with VPS hosting.

VPS is stands for virtual private server. In short, VPS is a server partitioning technology. In case of VPS every virtual server can install and also reboot separately with their own operating system.

VPS supports mainly two operating system, Or we can say that, based on the operating system VPS is differentiated into two types. The first one is Linux VPS hosting and the second one is Windows VPS hosting. There are many differences between linux vps hosting and windows vps hosting.

Linux VPS Hosting :

If you are searching for a reliable and cheap vps hosting then the linux vps hosting should be proper for you. Linux is a open source operating system. There is no license charges or other hidden charges. Linux is secure, reliable, flexible, cost effective operating system. So, Linux vps hosting provides a stable, sturdy yet cheap hosting solution.

Windows VPS Hosting :

If you wish to run custom Microsoft applications, scripts or softwares on your VPS, you have to hire windows based VPS hosting services. Windows vps is user friendly. Maximum hosting providers offer you with RDP to access your server. Your VPS is also smoothly accessible through the control panel which you choose with your plan. You can add and delete software or data to and from your VPS and you can optimize performance, scalability and throughput.

Price Factor :
The cheap costs involved in Linux VPS hosting packages is one of the most important reasons for its popularity. As it is open source, it is greatly cheaper than Windows VPS plans and you don’t need to spend anything on purchasing licenses.

On the other hand, if you wish to install and run custom Microsoft applications on your VPS,   a Linux plan won’t work for you. Windows server is the best to run Windows applications and softwares smoothly.

Your requirements, your budget and how you wish to use your VPS that would determine whether you choose Linux or Windows for your VPS hosting solution.

Step 1 : Disable system services
The most effective way to increase VPS performance is  to disable any system services those are not essential. Services those are not utilized will still utilize up valuable RAM and CPU time, and also possibly permit your server to be attacked remotely. If you do not require these services, why have them? Manage the startup scripts that start these services at boot time, and disable them.

Step 2: Configure MySQL properly

Another step to increase the accessible RAM (or allot more RAM to MySQL) is to set up the MySQL cache sizes. If your MySQL server instance is utilizing more memory, reduce the cache sizes. in addition, if MySQL gets bogged down with large requests, increase the MySQL cache.
Step 3: Configure Apache properly
With Apache 2.0, many system administrators and clients like have become embarrass as to the proper set up of the Apache worker threads. Find how much memory Apache is utilizing, and adjust the StartServers and MinSpareServers directives as required to free up more memory.

These steps should pass away the amount of RAM that your VPS uses by as much as 30-40%, which might save you quite a bit of money per month.

A virtual private server has a process of dividing a physical server into various servers. Every separated server has the appearance and abilities to run on its own dedicated machine. Every virtual server can run its own full-fledged operating system, and every server can be separately rebooted.

The technology of computer server partitioning is not new- it has been around especially with mainframe computers. But with the advent of virtualization software technologies, it has generated renewed interest

There are a large number of users who have a control problem with shared hosting and still cannot afford to use a dedicated server. Linux VPS Hosting is just the solution for such users. These private servers offer root access, guaranteed resources, a full-featured control panel, and complete web hosting technical support. Other services such as web design and ecommerce are also available.

Following are few of the ways of setup :

Round Robin DNS Load Balancing dedicated server :

It is basically DNS binded server that load-balances multiple dedicated web servers. This is normally known to be used for group of clusters. Some of the main advantages is that is very simple and can easily be implemented.

The only disadvantage is that the DNS server does not know if any server goes down. It knows only the difference of the IP and does not know by server port. The IP can be cached by others and request will not be forwarded to the other server.

Hardware Load-balancing dedicated server :

Hardware load-balancers route TCP/IP packet to different servers in a cluster. They are highly-reliable but with a cost. It used network gatewat to route traffic. The only disadvantage is that it is cheaper to software versions.

Software Load-balancing dedicated server :

These days, software load balancing dedicated servers are normally used which are integrated with web servers and application servers. They are much cheaper when compared to a hardware load-balancer and can easily be configured as per requirements. Unlike, Round-Robin, it can easily route based on different parameters. It requires additional hardware for complete setup of load-balancer.

Many companies make it difficult or impossible to have multiple domain hosting with one Web hosting account and may require you to purchase separate Web hosting space for each domain name. The problem with this is that you may receive 5GB worth of space per account and only use 1GB. This means that, with five separate domain names, you will be paying five times as much as you would be without this rule.
With Bodhost you will not face such problems.You can host multiple domains on one single VPS or Dedicated server.

Most of the people uses Linux OS because of stability. Linux is perhaps the most stable OS(operating system) in the world.

Why is Linux Operating System is stable?

Servers running Linux web hosting just might be more stable because Linux is an open source OS. The code is open to the public so that anyone can read it and suggest improvements or point out bugs. Over the years, Linux has been developed in many flavors such as Red Hat and Debian. Large number of people have contributed their time and effort for making Linux web hosting run faster and to provide simpler, more efficient and bug free code. With an open programming environment, improvements are made on a continual basis and problems are seen relatively quickly and solved with a minimum of difficulty.
When you are starting a new website, one of your chief concerns about it is stability. Any time that the website spends offline as a result of technical problems is time that your customers are unable to use your website, and this is bad for your bottom line. Businesses tend to want the most stable OS for their web sites to minimize the dreaded server crash.

Another issue that you have to consider when setting up a new online website is whether the OS they are using will be able to use the full range of software and scripts that they require. Again, Linux web hosting is a winner in this regard. Lots of major web hosting companies offer Linux web hosting and with so many people using it around the world anything that you can do with Windows hosting can also be done with Linux web hosting. Many of the most popular script packages on the web today are available in both Windows and Linux web hosting versions, with the Linux web hosting version generally being more stable and having all of the same features as their Windows cousins. This is of course my opinion and I am sure that there are some who may disagree.

Linux web hosting is typically available at the same price as Windows web hosting. So consider that for the same price you can get an operating system for your website on the world wide web which is:

1) stable
2) runs popular script packages
3) considered the best operating system in the world in terms of these criteria by many of the internet’s most well respected independent sources of judgement.

So getting your web server with the Linux operating system is particular important for companies which require to set up eCommerce websites. When customers depends on your website for sending in their orders, you need to make sure that you website is running twenty four hours a day.

#!/bin/bash

cd /etc/mail

make

newaliases

/etc/init.d/sendmail restart

It will first runs the make command, which creates a new sendmail.cf file from the sendmail.mc file and then compiles supporting configuration files in the /etc/mail directory according to the instructions in the file /etc/mail/Makefile. After thar it generates new e-mail aliases with the newaliases command, and then restarts sendmail.

To make the script executable use this command.

chmod 700 filename

You will need to run the script every time you change any of the sendmail configuration files described in the sections to follow.

The line in the script that restarts sendmail is only needed if you have made changes to the /etc/mail/sendmail.mc file, but It included it so that you don’t forget.

Note: When sendmail starts, it reads the file sendmail.cf for its configuration. sendmail.mc is a more user friendly configuration file and really is much easier to fool around with without getting burned. These sendmail.cf file is located in different directories depending on the version of RedHat you use. The /etc/sendmail.cf file is used for versions up to 7.3, and /etc/mail/sendmail.cf is used for versions 8.0 and higher and Fedora Core.

We support Sendmail on our Linux VPS Hosting packages
