Solved: Need help getting a web page to start a server.
Wont let me add the solved tag, say's im over the max. Removing 2 tags did not help.



No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial


One of my game servers keeps going offline and so I want to give the users the ability to bring it back up.
The easiest way I could think of is to create a web page that would execute a bash
script. Here is the code I used.

Code:
<?php

if ($_GET['run']) {
  $old_path = getcwd();
  chdir('/home/warmc/servers/snapshot/');
  
  $output = shell_exec("./teststart.sh");
  echo $output;

  chdir($old_path);
}
?>


<a href="?run=true">Click Me!</a>

My web page works and will execute the script but all it does is echo to the webpage.
I thought maybe it was because the web page user needs root access and I found a source that suggested adding the following to the sudoers file.


Code:
 www-data ALL=NOPASSWD: /path/to/script

The problem is that when trying to use visudo from Webmin Command Shell I get this.


Code:
 [host@Username ~]# visudo Error opening terminal: unknown. 
 visudo: /etc/sudoers.tmp unchanged 
 [host@Username ~]#

So how do I edit the sudoers file?
Am I on the right track?

git-instaweb

GIT-INSTAWEB(1) 						    Git Manual							   GIT-INSTAWEB(1)

NAME

       git-instaweb - Instantly browse your working repository in gitweb

SYNOPSIS

       git instaweb [--local] [--httpd=<httpd>] [--port=<port>]
		      [--browser=<browser>]
       git instaweb [--start] [--stop] [--restart]

DESCRIPTION

       A simple script to set up gitweb and a web server for browsing the local repository.

OPTIONS

       -l, --local
	   Only bind the web server to the local IP (127.0.0.1).

       -d, --httpd
	   The HTTP daemon command-line that will be executed. Command-line options may be specified here, and the configuration file will be
	   added at the end of the command-line. Currently apache2, lighttpd, mongoose, plackup and webrick are supported. (Default: lighttpd)

       -m, --module-path
	   The module path (only needed if httpd is Apache). (Default: /usr/lib/apache2/modules)

       -p, --port
	   The port number to bind the httpd to. (Default: 1234)

       -b, --browser
	   The web browser that should be used to view the gitweb page. This will be passed to the git web--browse helper script along with the
	   URL of the gitweb instance. See git-web--browse(1) for more information about this. If the script fails, the URL will be printed to
	   stdout.

       start, --start
	   Start the httpd instance and exit. Regenerate configuration files as necessary for spawning a new instance.

       stop, --stop
	   Stop the httpd instance and exit. This does not generate any of the configuration files for spawning a new instance, nor does it close
	   the browser.

       restart, --restart
	   Restart the httpd instance and exit. Regenerate configuration files as necessary for spawning a new instance.

CONFIGURATION

       You may specify configuration in your .git/config

	   [instaweb]
		   local = true
		   httpd = apache2 -f
		   port = 4321
		   browser = konqueror
		   modulepath = /usr/lib/apache2/modules

       If the configuration variable instaweb.browser is not set, web.browser will be used instead if it is defined. See git-web--browse(1) for
       more information about this.
