Step 1: Download the windows version of the httpd
from the official site. http://httpd.apache.org/download.cgi.
The file that I downloaded was httpd-2.2.21-win32-x86-no_ssl.msi
Step 2: Run .msi file which will open a wizard. Follow
the instructions given in the wizard to complete the installation.
Step 3: Once it is successfully installed, the Apache
Service Monitor icon will be shown on the windows task bar. Use this
to monitor the httpd server status.
Step 4: By default the httpd runs on port 80. Try
this URL http://localhost:80 on the browser
to verify the installation.
