What is Apache? • is a powerful, flexible, HTTP/1.1 compliant web server • implements the latest protocols, including HTTP/1.1 (RFC2616) • is highly configurable and extensible with third-party modules • can be customised by writing 'modules' using the Apache module API • provides full source code and comes with an unrestrictive license • runs on Windows NT/9x, Netware 5.x and above, OS/2, and most versions of Unix, as well as several other operating systems • is actively being developed • encourages user feedback through new ideas, bug reports and patches • implements many frequently requested features, including:
INSTALLATIONS & CONFIGURATIIONS -PRESENTED BY H. ANKUSH. JAIN
Step 1: Double-Click the Apache Executable and Get the Welcome Screen • Click Next
Step 2: Read the License • Make sure there's nothing that you can't agree to. Once you accept, you'll be held to the terms of the license.
Step 3: Read the README File • Scan the readme file to make sure there aren't any late minute bugs that would make this version crash on your computer.
Step 4: Provide Your Server Information • Fill in your Network Domain, server name, and administrator's email address. If this is not going to be hosted on the Internet, you can use "localhost" (without the quotation marks) as the network and server name.
Step 5: Typical Setup? • I usually select custom, so I know exactly what is being installed. But choosing typical is a lot faster.
Step 6: Review Custom Options • If you chose "Custom" review the options you have. Don't turn off any required modules. I recommend reading the description of all other modules, so you know what is being installed.
Step 7: You're Done • Click Finish and go check out your new Apache Web server.
