Start/Stop and Restart server by PHP

Tomek58 · 01-15-2009, 07:44 AM

Hello!
I would like write panel with start/stop/restart my server.

I start my server in console this command:

Quote:

screen -A -m -d -S hlds ./hlds_run1 -game cstrike -nomaster +exec server.cfg

And i write: ps x

Quote:

vz138:/# ps x
PID TTY STAT TIME COMMAND
1 ? Ss 0:00 init [2]
1692 ? Ss 0:00 SCREEN -A -m -d -S hlds ./hlds_run1 -game cstrike -no
1693 pts/1 Ss+ 0:00 /bin/sh ./hlds_run1 -game cstrike -nomaster +exec ser
1702 pts/1 S+ 18:26 ./hlds_i686 -game cstrike -nomaster +exec server.cfg
7727 ? Rs 0:00 vzctl: pts/2
7728 pts/2 Ss 0:00 -bash
7732 pts/2 R+ 0:00 ps x

It's OK. I wrote script SHELL: start.sh

Quote:

#!/bin/sh
screen -A -m -d -S hlds ./hlds_run3 -game cstrike -nomaster +exec server.cfg

And script: start.php

PHP Code:



<?PHP 
exec("sh /var/www/cs1/start.sh"); 
?>

But server isn't start. Why?

Because PHP runs as user apache or httpd and your script or cs server runs with different user.

You need to run apache as root, but thats a very very bad idea, or cs server which the same user rights as php is running.

I have lighttpd. So i change in lighttpd.conf:

Quote:

server.username = "www-data" >>>> server.username = "root"
server.groupname = "www-data" >>>> server.groupname = "root"

??

Now LIGHTTPD isn't start:

Quote:

vz138:/# /etc/init.d/lighttpd start
Starting web server: lighttpd2009-01-15 15:13:59: (server.c.706) I will not set uid to 0

Seems like lighttpd is build to not allowed to run the web server with root user, which is a super good idea. Try to run the lighttpd and cs server with a normal user, like "joe" ... you get my point, and make sure that the rights for the cs server belong to joe... because I suppose that server can run also as a normal user not just root.

Now LIGHTTPD isn't start:

The log told you exactly why it wouldn't start- It refuses to set it's id to root (which is a very good thing.) A better answer is to setup the cs server to run as the same user as the webserver (www-data).
