How to install Apache Tomcat on Ubuntu

I was trying to install Apache Tomcat on Ubuntu for my friend from repository but the version from the repositories simply didnt work . So I made it installed manually and here is the steps on how to do that .

Before you install Apache Tomcat, make sure you are having Java installed on your box .

sudo apt-get install sun-java6-jdk It will make the Java installed .

Once done , proceed with apache tomcat installation :

First of all, download and extract Tomcat from the apache site. You should make sure for latest version and adjust it accordingly in the following instruction .

wget http://mirror.olnevhost.net/pub/apache/tomcat/tomcat-6/v6.0.18/bin/apache-tomcat-6.0.18.tar.gz

tar xvzf apache-tomcat-6.0.18.tar.gz

Now we will move the tomcat folder to a permanent location.Preferably /usr/local/tomcat, but you could move it somewhere else if you wanted to.

sudo mv apache-tomcat-6.0.18 /usr/local/tomcat

Now we will handle the most important part . Apache Tomcat requires the JAVA_HOME variable should be set up properly. The best way to do this is to set it in .bashrc file.

The better method is editing your .bashrc file and adding the following line there.

vi ~/.bashrc

Add the following line:

export JAVA_HOME=/usr/lib/jvm/java-6-sun

At this point you can start tomcat by just executing the startup.sh script in the tomcat/bin folder.

But we will go for the automatic start option

To make tomcat automatically start when boot up , you can add a script to make it auto-start and shutdown.

sudo vi /etc/init.d/tomcat

Now paste in the following:


# Tomcat auto-start
#
# description: Auto-starts tomcat
# processname: tomcat
# pidfile: /var/run/tomcat.pid

case $1 in
start)
sh /usr/local/tomcat/bin/startup.sh
;;
stop)
sh /usr/local/tomcat/bin/shutdown.sh
;;
restart)
sh /usr/local/tomcat/bin/shutdown.sh
sh /usr/local/tomcat/bin/startup.sh
;;
esac
exit 0


You’ll need to make the script executable by running the chmod command:

sudo chmod 755 /etc/init.d/tomcat

Next step is actually linking this script to the startup folders with a symbolic link. Execute these two commands and we should be on our way.


sudo ln -s /etc/init.d/tomcat /etc/rc1.d/K99tomcat
sudo ln -s /etc/init.d/tomcat /etc/rc2.d/S99tomcat


All done and your Apache Tomcat should be running at FQDN:8080 or localhost:8080 . Open a browser and access it .

The final step is to set Apache Tomcat Manager login credentials should be added for your management .

Edit the following file


vi /usr/local/tomcat/conf/tomcat-users.xml


And Add the following and save .

< role rolename="manager"/>
< user username="PUT_ANY_USERNAME" password="PUT_ANY_PASSWORD" roles="manager"/>


Now restart apache tomcat and all should be set to go ……
