I have a wordpress php script running as a cron job. it's currently running once a minute per domain indefinitely.
/usr/bin/php -q /home/domain1/public_html/wp-content/plugins/tdw/postit.php > /dev/null 2>&1
The problem is my server is getting big with 50+ domains and the crons are running into each other causing errors or crashing the database.
is there a way that i can make it run sequentially? like run domain1 script wait one minute then run domain2...looping through the url list.
thank you for your help.
Put them in a bash script, like
#!/bin/bash
/usr/bin/php -q /home/domain1/public_html/wp-content/plugins/tdw/postit.php > /dev/null
sleep 60s
/usr/bin/php -q /home/domain2/public_html/wp-content/plugins/tdw/postit.php > /dev/null
sleep 60s
/usr/bin/php -q /home/domain3/public_html/wp-content/plugins/tdw/postit.php > /dev/null
sleep 60s
# and so on...
and start that from cron.
If the pathes are all alike except the domain name, you could also use a php script, which generates the correct path for every domain and then executes the script via exec(). For example, it could iterate over the contents of the /home folder via the directory functions of PHP. That way, you do not have to update your script when you add a domain.
A script like that would look like
<?php
$template = '/usr/bin/php -q /home/%s/public_html/wp-content/plugins/tdw/postit.php > /dev/null';
if ($handle = opendir('/home')) {
while (false !== ($entry = readdir($handle))) {
$command = sprintf($template, entry);
exec($command);
sleep(60);
}
}
?>
