How to make a crontrolpanel for apache sites with cronjobs, a2ensite, a2dissite and force-reload

Posted on 2009-05-14

I have created a php script that integrates with a mysql database with all my sites in it.
The script works perfectly when i run it in console on account with access to apache with the php script.php command.
But when i add it to crontab to run every 5 minute i get an e-mail saying "command not found: a2ensite". same thing with a2dissite.

Is there anything i am doing wrong in my script?
Or do i have to learn myself cgi?

The command beeing run is in the codefield.


|** Denne filen skal kjøre i crontab **|


$date = date("Y-m-d H:i:s");


// Lage funksjoner for å forenkle kroppen på filen

function mysqlconnect(){ // Koble til MySQL


	@mysql_connect($server,$username,$password) or die("DB: Access Denied");

	@mysql_select_db($database) or die("Unable to select database");


function mysqlrun($var){

	$result = mysql_query($var);

	return $result;




$db = mysqlrun("SELECT id, sitename, enabled FROM `a2_sites` WHERE cronthis = '1'");

$execforce = 0;

	while($sql = mysql_fetch_array($db)) {

	$execforce = 1;

	$sitename  = ""; //Tømme stringen

	$sitename  = $sql['sitename'];

		if($sql['enabled'] == 1) {

			mysqlrun("UPDATE `a2_sites` SET `cronthis` = '0' WHERE `id` =$sql[id] LIMIT 1;");

			exec("a2ensite $sitename");

			//echo "a2ensite $sitename\r\n";

		} else {

			mysqlrun("UPDATE `a2_sites` SET `cronthis` = '0' WHERE `id` =$sql[id] LIMIT 1;");

			exec("a2dissite $sitename");

			//echo "Croned disabled thingy<br>";

			//echo "a2dissite $sitename\r\n";



	if($execforce == 1) exec("/etc/init.d/apache2 force-reload");




// Sjekke sitene som eksisterer

array(exec("ls /etc/apache2/sites-available/", $sitesavailable)); // Sider som er tilgjengelige

array(exec("ls /etc/apache2/sites-enabled/", $sitesenabled)); // Sider som er aktiverte

$num_sitesavailable = count($sitesavailable);

$num_sitesenabled = count($sitesenabled);


$i = 0;

while($i < $num_sitesavailable){


	// Sjekke om siden er aktivert

	$enabled = 0; //Resette enabled status til Ikke Aktivert

	$in = 0;

	while($in < $num_sitesenabled){


		if($sitesenabled[$in] == "000-default") $sitesenabled[$in] = "default"; // Fiks for lokal standard fil

			if($sitesenabled[$in] == $sitesavailable[$i])

				$enabled = 1;





	$sitename = $sitesavailable[$i];



		$db = mysqlrun("SELECT sitename FROM `a2_sites` WHERE sitename = '$sitename'");

		$num = mysql_num_rows($db);

			if($num == 0){ 

				$isthere = 0;

			} else { $isthere = 1; }

		if($isthere == 0){ // insert

			mysqlrun("INSERT INTO `a2_sites` ( `id` , `sitename` , `lastupdate` , `cronthis` , `enabled` , `health` ) VALUES (NULL , '$sitename', '$date', '0', '0', '0');");

			//echo "Finnes ikke i SQL, inserting: $sitename\r\n";

		} else { // update

			//echo "UPDATE `a2_sites` SET `lastupdate` = '$date', `enabled` = '$enabled', `health` = '1',  WHERE `sitename` = '$sitename' LIMIT 1;\r\n";

			mysqlrun("UPDATE `a2_sites` SET `lastupdate` = '$date', `enabled` = '$enabled', `health` = '1'  WHERE `sitename` = '$sitename' LIMIT 1;");







// Check site health


$db = mysqlrun("SELECT id, sitename FROM `a2_sites` WHERE health = '1'");

while($sql = mysql_fetch_array($db)) {

	$id			= $sql['id'];

	$sitename	= $sql['sitename'];

	$isthere = file_exists("/etc/apache2/sites-available/$sitename");

	if($isthere == 0) mysqlrun("UPDATE `a2_sites` SET `health` = '0', `enabled` = '0' WHERE `id` = '$id' LIMIT 1;");

	//echo "Isthere = $isthere | UPDATE `a2_sites` SET `health` = '0', `enabled` = '0' WHERE `id` = '$id' LIMIT 1;\r\n";

You will need to supply the COMPLETE path to the command, cron does NOT execute the .profile (or .bash_profile) scripts and therefore you need to supply the complete path to your command and inside your script you would need to set the environment.
