Why I can't use the CATALINA_HOME environment variable?

  • 772

I am not yet a Linux guy and I have the following problem with environment variable.

So I want to add a permanent environment variable and I do in this way:

I open the /etc/profile file and I add this line at the end of this file:

CATALINA_HOME=/opt/apache-tomcat-8.0.24

Where /opt/apache-tomcat-8.0.24 is the folder that contain the tomcat installation (it contains the bin TomCat subfolder)

Then I save this file.

So I close the shell and I reopen it and I try to do:

andrea@andrea-virtual-machine:/$ sudo ./startup.sh
sudo: ./startup.sh: command not found

To start the server instead enter into /opt/apache-tomcat-8.0.24/bin/ and perform the command.

But as you can see I obtain an error. What am I missing?

command-line

  1. sudo ./startup.sh command will execute the startup.sh script in your current directory.

    This you should do:

    Add this line to /etc/profile for setting path while booting( Permanent change) 

    export CATALINA_HOME=/opt/apache-tomcat-8.0.24

    To set path temporarily execute above command in the current shell.

    and excute this:

    sudo $CATALINA_HOME/bin/startup.sh

    Two issues:

    • You also need to export the variable into the environment as follows:

      export CATALINA_HOME=/opt/apache-tomcat-8.0.24

    Since you are using /etc/profile, it won't take effect in X again, until you logout and in again of your xsession, not just your shell.

    • Also sudo cannot find ./startup.sh. You need to be in the same directory as this script. By enter it, it means first:

      cd /opt/apache-tomcat-8.0.24/bin/
