How to set up your own Web Server?

Web servers are quite common now a days, it can be used for many purposes..You can host your own website,your own blog, a forum or just some files...You can use it to access your data from anywhere in the world, you can use it to send files to your friends..and a lot of other cool stuff can be done!!
Doing so is simple ..First download WAMP , then install it, you could use the default settings, just make sure you place a valid administrator email address(which will be your own)..WAMP will ask you where to have the website.. the default option is c:\wamp.. you can change this to wherever you like.. this is where your website files would reside...
Once your done installing you need to make your website available on the internet..For this you first need to open up a port on your dsl modem/router..go to the modem/router config page(default:192.168.1.1 or 192.168.0.1) and port forward port number 80 to your computer.. it will ask for your computer's local ip address.. if you know it enter it , if you dont know it go to the command prompt and type ipconfig(normally your ip address should be 192.168.x.x).
Now your website will be available online and anybody can access it from the web.. but what if you have a dynamic ip i.e. your ip address changes everytime.. then it would be very difficult to acces your website.. therefore its better you register to a service called NO-IP , use the no-ip free service.. it is free of cost and you can get a free domain name like(yourname.sytes.net or yourname.no-ip.com).. you can choose from various available domain names..if you want a primary domain name like yourname.com then you need to register for the no-ip plus service , this is not a free service you have to pay around 32$ a year..
Once you registered to that site and have chosen the domain name , you need to download the no-ip client,this is used to synchronize your ip address with your domain name as your ip keeps changing..even if you have a static ip, you can use this service...download the no-ip client and enter your username and password you created when you registered..
One last thing, incase you use any windows firewall or any other firewall service.. make sure you allow port 80 as it maybe blocked by default.. For the windows firewall, go to control panel and click on windows firewall there you will find something called as add exception/port there enter the port name , this will ensure that your firewall is not blocking any access to your pc...
Thats it!! your done you can go to any computer in the world and just type http://yourname.sytes.net or whatever domain you created and you will be accessing content which is placed on c:\wamp or the directory you chose..
Cheers!!!
