Hi guys,
I am searching away to connect from
Server A to server B
and i want to let php execute some commands, like restarting apache etc, i know that it is possible with php, but how i don't now.
Just a tutorial or a little script on how you can restart apache through php would help a lot!
Thanks in advanced
Greetz,
Dion

Something like this should do it:
or install sudo and add
www-data ALL=(ALL) NOPASSWD: /usr/sbin/apachectl
to /etc/sudoers.
then add this to your page:
<?php
$submit = $_POST['submit'];
if($submit == "Restart") {
$message = '<p>Apache is being restarted</p>';
exec('/etc/init.d/httpd graceful');
$message .= '<p>Apache was restarted</p>';
}
echo '<html><head><title>Apache Restart</title></head><body>';
echo $message;
echo '<form action="" method="post">
<input type="submit" name="submit" value="Restart"></form>';
?>
or install sudo and add
www-data ALL=(ALL) NOPASSWD: /usr/sbin/apachectl
to /etc/sudoers.
then add this to your page:
passthru("sudo apachectl graceful", $output_var);

itypeos, it sounds to me like this guy may be farily new to the subject. Since i barely understand what you're saying, i'd recommend possibly offering a better explaination...
Secure Shell2 <-- That is the only reference i know of for PHP/SSH stuff.
I've never used/looked into the subject at all myself, so that is all i can offer you. Personally though, i know php wasn't built to preform operations on a remote server (don't get me wrong, it can, but it's functionality is limited). That link i provided should be a bit more enlightening though.

My bad, ok well this should be a bit easier.
Make a file called httpd_reload.c and add this:
Put this file anywhere you want then add this to anywhere you want but just make sure you change the patch below to where yo uput the httpd_reload.c:
PHP code:
Make a file called httpd_reload.c and add this:
/***********************************************************
* make sure to chmod +s the binary after compiling:
* cc -o httpd_reload httpd_reload.c; chmod +s httpd_reload
***********************************************************/
#include <stdio.h>
#include <stdlib.h>
int main() {
if (!setuid(geteuid())) {
system("/bin/echo '/sbin/service httpd reload > /dev/null 2>&1' | /usr/bin/at now");
} else {
printf("Couldn't set UID to effective UID\n");
return 1;
}
return 0;
}
Put this file anywhere you want then add this to anywhere you want but just make sure you change the patch below to where yo uput the httpd_reload.c:
PHP code:
exec('/path/to/httpd_reload');
