Install Apache Tomcat 8 on Ubuntu 14.04

In this tutorial, we will show you how to install Apache Tomcat 8 on Ubuntu 14.04. For those of you who didn’t know, Apache Tomcat is an open-source web server and servlet container developed by the Apache Software Foundation. It implements the Java Servlet, JavaServer Pages (JSP), Java Unified Expression Language, and Java WebSocket specifications from Sun Microsystems and provides a web server environment for Java code to run in.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you through the step-by-step installation of apache tomcat 8 on ubuntu 14.04.

Install Apache Tomcat 8 on Ubuntu 14.04

Step 1. JAVA is the first requirement of Tomcat installation.

Add the repository:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java

Update apt and install Java 8:

sudo apt-get update
sudo apt-get install oracle-java8-installer

You can also verify it, by issuing the following command.

java -version

Step 2. Download and extract Tomcat packages.

After installing and configuring JAVA on the system, now it’s time to download the latest version of Apache Tomcat.

cd /opt
wget http://www.apache.org/dist/tomcat/tomcat-8/v8.0.33/bin/apache-tomcat-8.0.33.tar.gz
tar -xvf apache-tomcat-8.0.21.tar.gz

Add tomcat user and group:

ln -s /opt/apache-tomcat-8.0.21 /opt/tomcat-latest
chown -hR tomcat8: /opt/tomcat-latest /opt/apache-tomcat-8.0.21

Step 3. Configure environment variables.

Before starting Tomcat, configure CATALINA_HOME environment variable in your system using the following commands.

# echo "export CATALINA_HOME=\"apache-tomcat-8.0.21\"" >> ~/.bashrc
# source ~/.bashrc

Step 4. Configure Tomcat to run as a service.

cd /opt/apache-tomcat-8.0.21/bin
./startup.sh

You will get the following output.

Using CATALINA_BASE:   /var/local/apache-tomcat-8.0.21
Using CATALINA_HOME:   /var/local/apache-tomcat-8.0.21
Using CATALINA_TMPDIR: /var/local/apache-tomcat-8.0.21/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /var/local/apache-tomcat-8.0.21/bin/bootstrap.jar:/var/local/apache-tomcat-8.0.21/bin/tomcat-juli.jar
Tomcat starte

You can verify the service running, by default tomcat runs on port no 8080.

[[email protected] ~]# netstat -antup | grep 8080
tcp        0      0 0.0.0.0:8080                0.0.0.0:*                   LISTEN

Step 5. Finally, open Tomcat from your browser, go to your IP or domain with the 8080 port (because Tomcat will always run on the 8080 port) as an example: mydomain.com:8080, replace mydomain.com with your IP or domain.

To shutdown Tomcat you can simply run the shutdown script in the same folder like this:

/opt/apache-tomcat-8.0.21/bin/shutdown.sh

Step 6. Setup user accounts.

Configure Tomcat users so they can access admin/manager sections. You can do this by adding the users in the conf/tomcat-users.xml file with your favorite text editor. Add this text to the file:

nano /opt/apache-tomcat-8.0.21/conf/server.xml

Place the following two lines just above the last line.

<!-- user manager can access only manager section -->
<role rolename="manager-gui" />
<user username="manager" password="_SECRET_PASSWORD_" roles="manager-gui" />

<!-- user admin can access manager and admin section both -->
<role rolename="admin-gui" />
<user username="admin" password="_SECRET_PASSWORD_" roles="manager-gui,admin-gui" />
