Apache Tomcat is an open source software implementation of the Java Servlet and Java Server Pages technologies. You’ll run applications within Tomcat using the OpenJDK implementation of the Java development environment.
Before following this guide, ensure that your system is up to date and that you have completed the Setting Up and Securing a Compute Instance. If you are new to Linux server administration, we recommend reviewing our beginner’s guide and the article concerning systems administration basics.
Prerequisites
Before you begin installing and configuring the components described in this guide, please make sure you’ve followed our instructions for setting your hostname. Issue the following commands to make sure it is set properly:
hostname
hostname -f
The first command should show your short hostname, and the second should show your fully qualified domain name (FQDN).
You should also make sure your system is up to date. Enter the following commands, one by one, and install any available updates:
apt-get update
apt-get upgrade
Install Apache Tomcat
To install Tomcat, issue the following command:
apt-get install tomcat6
tomcat6 package. OpenJDK is pulled in by the default-java meta package in Ubuntu.You may also want to install the tomcat6-docs, tomcat6-examples, and tomcat6-admin tools which provide web-based applications that document, test, and allow you to administer Tomcat. You can install all three with the following command:
apt-get install tomcat6-docs tomcat6-examples tomcat6-admin
Tomcat should now be totally functional, following installation and your next system reboot. If you need to start, stop, or restart Tomcat you can use the following commands:
/etc/init.d/tomcat6 start
/etc/init.d/tomcat6 stop
/etc/init.d/tomcat6 restart
Test and Use Tomcat
You can test your Tomcat installation by pointing your browser at http://[yourdomain-or-ip-address]:8080/. By default, files are located in the /usr/share/tomcat6 directory. To configure the admin area, you’ll need to add the following lines to the end of your tomcat-users.xml file, substituting your own username and password. Make sure you keep the “manager” role.
- File: /etc/tomcat6/tomcat-users.xml
1 2<role rolename="manager"/> <user username="username" password="examplemorris" roles="manager"/>
Issue the following command to restart the Tomcat server, which will allow this change to take effect:
/etc/init.d/tomcat6 restart
Congratulations! You know have a working Apache Tomcat installation.
