Apache Tomcat on Ubuntu 12.04 (Precise Pangolin)
Updated by Linode
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 getting started guide. If you are new to Linux server administration, we recommend reviewing our beginner’s guide and the article concerning systems administration basics.
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
OpenJDK will be installed as a dependency when you install the
tomcat6package. OpenJDK is pulled in by the
default-javameta package in Ubuntu.
You may also want to install the
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:
1 2 3
/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.
<role rolename="manager"/> <user username="squire" password="examplemorris" roles="manager"/>
Issue the following command to restart the Tomcat server, which will allow this change to take effect:
Congratulations! You know have a working Apache Tomcat installation.
