If you want to be able to redirect blah.domain.com to domain.com/blah/ so that blah.domain.com is shown in the address bar here’s a quick and dirty how to:

First off if you want any subdomain to be able to be redirected first you need to set-up your DNS correctly. In my case this was as simple as going to the people that host my domain and adding an A record with the wildcard * that pointed to my server’s ip address. Bear in mind your DNS settings may take a while to work so be patient. Before you proceed you should check that anything.domain.com resolves to the ip address of your server. You can check this by running:

ping iloveapache.domain.com

The next step is to set-up the virtual host to respond to the wildcard subdomains. In the case of plesk you have to set-up a vhost.conf file but on any other apache installation you can just edit httpd.conf and look for the that corresponds to your site. If you are using Plesk you will need to ssh in to your server and create a vhost.conf file if it doesn’t already exist here where is your domain:

/var/www/vhosts//conf/vhost.conf

Open that file with the command line editor of your choice and add the following directives:

ServerAlias *.domain.com
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.* [NC]
RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.com
RewriteCond /var/www/vhosts/domain.com/httpdocs/%1 -d
RewriteRule ^(.*) /%1/$1 [L]

Substitute domain.com for your domain. Now here’s a quick walkthrough how these rules work. The first line ServerAlias *.domain.com tells apache to accept anysubdomain.domain.com.

Next the rewrite rules work as follows:

1. The first line of mod_rewrite !^www.* only matches urls that don’t begin with www. You don’t want to redirect www.domain.com to www.domain.com/www/ do you? Note: you could add additional lines like these to prevent re-writing other subdomains like secure.domain.com if that should not be redirected to domain.com/secure/
2. The second line ^([^\.]+)\.*$ captures into a backreference anything that doesn’t have a period e.g. the subdomain. The plus makes sure that there is at least one character that matches.
3. The next condition checked is that the directory captured into the backreference does actually exist hence the -d.
4. This last line ^(.*) /%1/$1 [L] takes the requested path and dumps it into a back reference and then rewrites it to point to the a directory (the subdomain backreference captured in the Rewrite conditions above) . In other words %1 is the subdomain backreference and $1 is the path backreference (that captured by .*). The important thing to rember is you can refer to backreferences in rewriteCond lines with % and backreferences in rewriteRules with $. Lastly the [L] (last) means doen’t further rewrite this URL. Note: You might want to leave this out if you are doing any subsequent rewrites, be sure to test what you have set-up thoroughly!!!

And then whether are using Plesk or not you need to restart apache e.g:

service httpd restart

In this tutorial, apache2 server is installed through wamp server for PHP under c:/wamp/Apache2.

Download and install

• Java 1.5 JDK JDK 5.0 Update 7
• Tomcat 5.5.17 apache-tomcat-5.5.17.tar.gz
• mod_jk 1.2.18 mod_jk-apache-2.x.xx.so

Configuration

• Java JDK path : C:\jdk1.5.0_07
• Apache path : C:\wamp\Apache2
• Tomcat path : C:\tomcat5
• JSP/Servlet webroot (via Apache2/mod_jk) : C:\tomcat5\webapps
• JSP/Servlet webroot (via native Tomcat server, port 8080) : C:\tomcat5\webapps
• Access JSP/Servlet pages via Apache2/mod_jk : http://localhost/[jkmount-mapped url of your webapp]
• Access native Tomcat server : http://localhost:8080/

Unpack and place Tomcat5 and mod_jk

• Unpack file apache-tomcat-5.5.17.tar.gz under directory C:\
• Rename directory C:\apache-tomcat-5.5.17 to C:\tomcat5
• Rename file mod_jk-apache-2.x.xx.so to mod_jk.so, and place under directory C:\wamp\Apache2\modules. In wamp its already compiled and installed under c:/wamp/Apache2/modules

Configuration and Setup

• How to set environment variable on windows+unix
• Create empty file C:\wamp\Apache2\conf\workers.properties, insert code…

Edit file C:\wamp\Apache2\conf\httpd.conf, insert code

If you dont want to mount some files or directories, you can exclude using JkUnMount

Install and Start Tomcat

Tomcat can be installed as a Service or started as a Standalone Console application. Note to make sure that Apache has been started at this point.

To change Host Name Locally modify hosts file which is located under below specified path and add new hostname whatever you like for testing locally.

C:\WINDOWS\system32\drivers\etc\hosts

To modify URL and remove webapps name from url you have to do below steps.

Create below specified file under specified path and insert that code.

This for default localhost application.

conf/Catalina/localhost/ROOT.xml

For your custom application you have to add code as specified below.

Where $host is your custom web application.

Add a configuration file for the host

mkdir conf/Catalina/$host

cat >conf/Catalina/$host/ROOT.xml

Main step is to add ROOT folder under your webapps/$host folder like specified below

$tomcatdir/webapps/$host/ROOT/all the files

Next You have to modify server.xml file to add context paths and host

Example:

For as many applications you have to apply
