Steps :
Installing Java SDK
Step 1: SSH into the server using the following command
ssh –X root@ip-address-of-server
Then provide the root password. Please note that you need to use the root (admin) account itself, since you need super-user privileges to install applications in the server.
Step 2: Install jpackage-utils in the server using
yum install jpackage-utils
You can also get the packages (using wget) from http://www.jpackage.org/ and install them manually.
This will automatically pull the packages from the repository and install them
Step 3: Now we are going to install the Java SE Development Kit 6u22 for Linux. You may check this site to find whether this is latest version or not.
Since I’m going to use wget, I need a direct link to download the package.You can grab the package from here
http://techblog.googlecode.com/files/jdk-6u22-linux-i586-rpm.bin
Now use wget and pull this package to your server.
Step 4: Once it has been downloaded directly to the server, change the permissions accordingly as shown below:
chmod +x package-name.bin
Now issue the following command and verify that Java has been installed properly.
java –version
Installing Tomcat
Since Apache Tomcat is available in the repository, you can use the install command for installing it:
yum install tomcat*
This will install the server.
But in my case, it installed tomcat5 – which is an old version. The new version has a better memory management utility. So I had to remove the installation
remove yum
Installing Tomcat6 manually
As of today the latest version is 6.0.29. So we use the wget utility and download the package from the server:
wget http://apache.mirror.testserver.li/tomcat/tomcat-6/v6.0.29/bin/apache-tomcat-6.0.29.tar.gz
Please note that it is better to download this file to the /opt directory. (You can do this either by ‘cd-ing’ to the directory before issuing the wget or moving the file to /opt once the file has been downloaded).
Now untar the tarball using
tar –xvfz tarball-name.tar.gz
This will extract the items in the tarball and now you need to go to the bin directory in the extracted directory and run the startup.sh script. That’s it!
Now go to localhost:8080 (you may use Lynx for this) and verify that tomcat is running:
lynx
press g
enter “localhost:8080”
NOTE: Now you can try it at ip-address-of-server:8080. Please note that sometimes the datacentre may not have opened the port 8080. In my case, since Nazdrovia is using Planet Inc as the datacentre for providing the frontend and Amazon EC2 as backend, I had to ask them to open the port. So if you are getting a ‘server not found’ error, it is due the firewall – you may ask the datacentre to open it.
Starting Apache Tomcat during bootup
It is hard to run the start-up script manually every time you restart the server. So you may add the location of the script to
nano tomcat-users.xml
Now you need to add the following lines to that xml file:
Please note that you have to change the default passwords of the existing users due to security reasons. Once you have done that you can login to the admin and manager pages :
ip-address-of-server:8080/admin
ip-address-of-server:8080/manager
Managing the service
You can start or stop the tomcat service using the following commands:
/etc/init.d/tomcat6 start
/etc/init.d/tomcat restart
/etc/init.d/tomcat stop
Have fun and enjoy!

Starting Apache Tomcat during bootup
It is hard to run the start-up script manually every time you restart the server. So you may add the location of the script to
/etc/rc.d/rc.local And it will be executed automatically every time you boot the system.Please note that if you are using a Debian based distribution, then the location of the above mentioned file is at:
/etc/rc.local Admin and Manager roles You need to assign admin and manager roles to the tomcat users in order to manage web apps using a web based interface. (Please note that if you put anything in the web-apps directory of the server, it will be deployed automatically).You can do this by going to the new folder you created by extracting the tarball and editing the tomcat-users.xml file (/conf/tomcat-users.xml).nano tomcat-users.xml
Now you need to add the following lines to that xml file:
Please note that you have to change the default passwords of the existing users due to security reasons. Once you have done that you can login to the admin and manager pages :
ip-address-of-server:8080/admin
ip-address-of-server:8080/manager
