When working with large as well as not very large projects it is often feasible to move the execution of some especially complex agents to Cron.
- For a start, we will fully disable the execution of hit agents. To this effect, the following command should be executed on the php console of the administrative menu of the Bitrix product /bitrix/admin/php_command_line.php?lang=en:
COption::SetOptionString("main", "agents_use_crontab", "N");
echo COption::GetOptionString("main", "agents_use_crontab", "N");
COption::SetOptionString("main", "check_agents", "N");
echo COption::GetOptionString("main", "check_agents", "Y");
The result of the execution should be NN
.
- Remove from the file /bitrix/php_interface/dbconn.php the definitions of the following constants:
define("BX_CRONTAB_SUPPORT", true);
define("BX_CRONTAB", true);
And add:
if(!(defined("CHK_EVENT") && CHK_EVENT===true))
define("BX_CRONTAB_SUPPORT", true);
- Next, we create a file for agent testing and system message distribution /bitrix/php_intarface/cron_events.php:
<?
$_SERVER["DOCUMENT_ROOT"] = realpath(dirname(__FILE__)."/../..");
$DOCUMENT_ROOT = $_SERVER["DOCUMENT_ROOT"];
define("NO_KEEP_STATISTIC", true);
define("NOT_CHECK_PERMISSIONS",true);
define('CHK_EVENT', true);
require($_SERVER["DOCUMENT_ROOT"]."/bitrix/modules/main/include/prolog_before.php");
@set_time_limit(0);
@ignore_user_abort(true);
CAgent::CheckAgents();
define("BX_CRONTAB_SUPPORT", true);
define("BX_CRONTAB", true);
CEvent::CheckEvents();
?>
- And add this script to Cron:
*/5 * * * * /usr/bin/php -f /home/bitrix/www/bitrix/php_interface/cron_events.php
After that, all the agents and sending of system messages will be processed under cron every 5 minutes.
To avoid building up a queue for sending mail messages, the parameter responsible for a number of mail events processed at a time must be changed. To this effect, we have to run the following command on php console:
COption::SetOptionString("main", "mail_event_bulk", "20");
echo COption::GetOptionString("main", "mail_event_bulk", "5");
