To run root commands from Tomcat on Linux, you can follow these steps:

  1. Login to your Linux server as the root user or a user with sudo privileges.
  2. Open a terminal or command prompt.
  3. Navigate to the Tomcat installation directory. This directory is often located at /opt/tomcat or /var/lib/tomcat.
  4. Open the conf/tomcat-users.xml file in a text editor.
  5. Add a new user with the required roles to access the root privileges. Here is an example: Replace "admin" with your desired username and "password" with your preferred password. You can add multiple users with different roles as necessary.
  6. Save the changes and close the file.
  7. Restart the Tomcat server using the appropriate command. For example, sudo systemctl restart tomcat or /etc/init.d/tomcat restart.
  8. Open a web browser and go to http://localhost:8080/manager/html. Replace localhost with your server's IP or hostname if necessary.
  9. Enter the username and password specified in the tomcat-users.xml file.
  10. After successfully logging in, you will see the Manager App page. From here, you can execute root commands by clicking on the "Open Shell" button.
  11. In the shell console, you can run root commands by prefixing them with sudo. For example, to list the contents of the root directory, you can run sudo ls /.

Note: Running root commands from a web application like Tomcat can be a security risk. Make sure to properly secure your Tomcat server, restrict user roles, and limit root access to trusted individuals or roles.
