Where to Find catalina_base and catalina_home for Tomcat6 on Ubuntu

Ubuntu 11

In this article, we will guide you through the process of locating the directories for catalina_base and catalina_home in Tomcat6 on an Ubuntu system. Understanding these directories is crucial for the correct operation of your Tomcat server.

Quick Answer

The default locations for catalina_base and catalina_home in Tomcat6 on Ubuntu are /var/lib/tomcat6 and /usr/share/tomcat6, respectively. These values can be found in the /etc/default/tomcat6 file. If the environment variables are not set during installation, you can manually locate the directories by checking the /etc/init.d/tomcat6 file. However, it is not possible to answer the title of the post in just a few sentences.

Introduction to catalina_base and catalina_home

Before we dive into the specifics, let’s briefly understand what catalina_base and catalina_home are.

  • catalina_home: This is the directory path where the binary distribution of Tomcat is stored. It contains the core Tomcat binaries, libraries, and scripts required to run the Tomcat server.
  • catalina_base: This directory path is used for storing the runtime configuration, log, and application files.

In a standard Tomcat installation, catalina_home and catalina_base point to the same directory. However, if you are running multiple instances of Tomcat on a single machine, catalina_home will point to the common binaries and each instance will have its own catalina_base directory.

Default Locations

By default, on an Ubuntu system, catalina_home is set to /usr/share/tomcat6, and catalina_base is set to /var/lib/tomcat6. These values are stored in the /etc/default/tomcat6 file.

Locating the Directories

If the environment variables are not set during the installation, you can manually locate the directories by checking the /etc/init.d/tomcat6 file. This file contains the startup script for Tomcat and it declares the catalina_home and catalina_base variables.

  1. Open the /etc/init.d/tomcat6 file using a text editor. You can use the nano command for this:
sudo nano /etc/init.d/tomcat6
  1. In the file, look for the lines that define catalina_home and catalina_base. They should look something like this:
CATALINA_HOME=/usr/share/tomcat6
CATALINA_BASE=/var/lib/tomcat6

Setting the Environment Variables

Once you have located these lines, you can manually set the environment variables by exporting them to the OS variables. This can be done by adding the following lines to your .bashrc or .bash_profile file:

export CATALINA_HOME=/usr/share/tomcat6
export CATALINA_BASE=/var/lib/tomcat6

After saving the file, run source ~/.bashrc or source ~/.bash_profile to apply the changes. This will make the catalina_home and catalina_base variables available to all terminal sessions.

Alternatively, you can use the export command directly in the terminal to set the variables:

export CATALINA_HOME=/usr/share/tomcat6
export CATALINA_BASE=/var/lib/tomcat6

These variables will be visible on the ENV command and can be used by other software.

Conclusion

In this article, we have shown you how to locate and set the catalina_base and catalina_home directories for Tomcat6 on Ubuntu. It’s important to note that the exact locations of catalina_home and catalina_base may vary depending on your system configuration. The steps above should help you locate and set these directories manually.

Remember, understanding these directories and their roles is crucial for the correct operation of your Tomcat server. Happy coding!
