How To Install Apache Tomcat on Ubuntu

About Apache Tomcat

Apache tomcat is a Java based application server released by the Apache Software Foundation. It is a web server and a servlet container for Java web applications.

Setup

Tomcat installation required dependency as Java and this tutorial will include a step on how to install that platform.

Step 1 : Install Java

Step 2 : Install Tomcat7

Note : You do need to have a user with sudo privileges for this tutorial.

Step 1  : Install Java

We installed the entire Apache Tomcat server on our virtual server in the previous step. Before we can use it, however, we do need to have Java installed on the VPS as well. If you currently do not have java, you can download it quite easily with apt-get.

sudo apt-get install default-jdk

Once you have Tomcat and Java installed on the virtual private server, all that remains is to start them.

OR

For Installing Oracle JDK

sudo apt-add-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

Also ensure your JAVA_HOME variable has been set to:

/usr/lib/jvm/java-8-oracle

Step 2 : Install Tomcat

The most recent version of Tomcat is 7, and it can be easily downloaded through apt-get or from the Apache Tomcat site.

You can download it through apt-get by typing:

sudo apt-get install tomcat7

To download tomcat from their site, copy the link for the tar.gz package under the “Core” section and begin the download. You will get a link that originates from one of Apache’s many mirrors, making the command look mostly like this (although coming from a different site).

wget http://apache.mivzakim.net/tomcat/tomcat-7/v7.0.57/bin/apache-tomcat-7.0.57.tar.gz

After the download completes, untar the file.

tar xvzf apache-tomcat-7.0.57.tar.gz

Finish up the Tomcat installation on the VPS by moving the files to a convenient directory.

sudo mv apache-tomcat-7.0.57  ~/path/to/tomcat

Step 3 : Configure .bashrc

In order to start Tomcat, we need to add it as an environment variable in the /.bashrc file.

sudo nano ~/.bashrc

You can add this information to the end of the file:

export JAVA_HOME=/usr/lib/jvm/default-java

For Oracle JDK:

export JAVA_HOME=/usr/lib/jvm/default-java

Path Setup For Tomcat7

export CATALINA_HOME=~/path/to/tomcat

Save and exit out of .bashrc. You can make the changes effective by restarting the bashrc file.

. ~/.bashrc

Once you have Tomcat and Java installed on the virtual private server, all that remains is to start them.

For Starting tomcat7:

sudo service tomcat7 start

For Stoping tomcat7:

sudo service tomcat7 stop

For Restart tomcat7:

sudo service tomcat7 start
