Run specific sudo commands in wildfly

I want to run specific commands with sudo in my servlet in wildfly.

I know that I can run specific commands with the tomcat user:

tomcat ALL=(root) NOPASSWD: /home/jur/virt.sh, /home/jur/createdisk.sh

I tried with the user 'widlfly' but that doesn't work. Now I don't know what the name of the wildfly user is. My servlet can't run the commands with sudo.

In my servlet I have this: 

ProcessBuilder pb = new ProcessBuilder("sudo /home/jur/createdisk.sh " + parameter);

wildfly gives the error: "Java.io.IOExeption: Cannot run program "sudo /home/jur/createdisk.sh parameter": error=2, No such file or directory"

When I do the same in the terminal with the user 'jur', it works perfectly.

Solution

  • Constructor of ProcessBuilder class takes multiple arguments and the first one needs to be program name and following are arguments of the program.

    For example calling ProcessBuilder pb = new ProcessBuilder("ls -l") will give same error as you mentioned, but calling ProcessBuilder pb = new ProcessBuilder("ls", "-l") is going to be successful.

    Correct syntax in your case should be ProcessBuilder pb = new ProcessBuilder("sudo", "/home/jur/createdisk.sh", parameter);
