Installing Tomcat 6 on CentOS 5.5 Tutorial

Apache Tomcat is an open source software implementation of the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed under the Java Community Process.

So before we start just some general house keeping. The base CentOS 5.5 server hostname and IP address that we’ll be using in this tutorial:

* (IP

The Tomcat 6 Server will eventually be available on

The assumption, for this Tomcat 6 and CentOS 5.5 tutorial, is that you are running as root and have a medium understanding of the software required but if you’re Awesome that’s good enough.

Install Yum Priorities

For a brief overview on and how to configure Yum Priorities you can follow the instructions outlined in our Install YUM Priorities on CentOS tutorial.

# yum install yum-priorities

Install the EPEL i386 YUM Repository

# rpm -Uvh

Install the RPMForge i386 YUM Repository

# rpm -Uvh

Install the JPackage Project repository

Install Java

We just used the openjdk that available via the repositories but if you prefer Sun JDK the download it and install it.

Install Tomcat6

Add in JAVA_HOME under the CATALINA_TMPDIR reference

Start the Tomcat 6 service

Browser to your newly installed Tomcat6 Server (remember port 8080)

    you may encounter a “Missing Dependency: /usr/bin/rebuild-security-providers” error when attempting the final yum install tomcat6.

    The problem & solution are documented here

    The workaround is:
    rpm -Uvh

    Update: In particular tomcat failed to start ( after running alternatives ) with:
    Class loader creation threw exception java.lang.NoClassDefFoundError:
    Something is still missing it seems

    In Centos 5.6, when the next error:nnMissing Dependency: /usr/bin/rebuild-security-providers is needed by package java-1.4.2-gcj-compat- solve this problem;nnrpm -i

    After trying to work with the CentOS packaged version of Tomcat, I’ve realized that I’m much better off getting a nice vanilla install from Apache and installing it myself. It’s unclear to me why packagers choose to alter or remove functionality from the software they package, but they have with Tomcat (the start jdpa option is missing, for example), and it’s a giant pain in the posterior to deal with.

    I prefer to live in a world where Tomcat is installed the same on every machine I look at, than a world in which every app on a specific CentOS box is installed the same but those apps are also missing key features.

    First off, thanks for this article!

    Secondly, I had an issue where tomcat installed successfully (ie no errors) but I couldn’t access http://server:8080.  The service wouldn’t stop, only start, and I was seeing errors like this in the /var/log/tomcat6/catalina.out:

    SEVERE: Class loader creation threw exception
       at org.apache.catalina.startup.Bootstrap.createClassLoader(
       at org.apache.catalina.startup.Bootstrap.initClassLoaders(
       at org.apache.catalina.startup.Bootstrap.init(
       at org.apache.catalina.startup.Bootstrap.main(

    The resolution was to make sure that the JAVA_HOME directory was set correctly.  To do so:

    $ vim /usr/share/tomcat6/conf/tomcat6.conf

    # Add in JAVA_HOME under the CATALINA_TMPDIR reference

    $ service tomcat6 restart

    I was then able to get to http://server:8080!

    Thank you for the feedback. I have amended the document with your suggestion.

  • Allen Williams

    …like a charm! except i have 64bit centos so i had to use some common cents to change a few things, including java_home which i found at /usr/lib/jvm/java-1.6.0-openjdk- … also be sure to install repositories for 64bit also.
