Integrate Apache and Tomcat

This integration is to provide more security on hosting.

1. Install Apache2.2, Tomcat5.5 and libapache2-mod-jk 1:1.2.25-2

root # apt-get install apache2 tomcat5.5

root # apt-get install libapache2-mod-jk

2. Enable jk module in apache if not enabled.

root # a2enmod jk

3. Restart Apache

root # /etc/init.d/apache2 stop

root # /etc/init.d/apache2 start

4. Create/Edit jk.conf file in /etc/apache2/mods-available to contain the following contents and create a soft link from apache2/mods-enabled

<IfModule mod_jk.c>

JkWorkersFile /etc/apache2/workers.properties

JkLogFile /var/log/apache2/mod_jk.log

JkLogLevel debug

JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

JkRequestLogFormat "%w %V %T"

</IfModule>

5. Create a file workers.properties in /etc/apache2/ with contents,

workers.tomcat_home=/etc/tomcat-5.5/ # Tomcat Installation Directory

workers.java_home=/usr/lib/jvm/java-6-sun-1.6.0.07/ # Java Installation Directory

ps=/

# Worker properties

worker.list=ajp13 # This name should be given in the JkMount

worker.default.port=8009

worker.default.host=localhost

worker.default.type=ajp13

worker.default.lbfactor=1

6. In /etc/apache2/sites-available/default, add the following at the end of the file.
   <VirtualHost *>

ServerName test.otc.nic.in

DocumentRoot /usr/share/tomcat5.5-webapps/ROOT

ErrorLog /var/log/apache2/error.log

Alias / "/usr/share/tomcat5.5-webapps/ROOT"

<Directory "/usr/share/tomcat5.5-webapps/ROOT">

Options Indexes +FollowSymLinks

</Directory>

JkMount /* ajp13

</VirtualHost>

7. Restart Apache

root # /etc/init.d/apache2 stop

root # /etc/init.d/apache2 start
