TYPO3 Scheduler什么都不做

Question

I've written a scheduler task. Its working fine on my maching. Unfortunately its not working on my remote machine.

The machine is a freeBSD with php7.0 php-fpm running. The cron looks like:

**MAILTO=mail@falk-roeder.de
@weekly /usr/local/bin/letsencrypt.sh -c
* * * * * php /var/www/alpha/beta/gamma/typo3/cli_dispatch.phpsh scheduler
#* * * * * php -r 'echo function_exists("foo") ? "yes" : "no";'

the last crontab is executed (if I comment it in) and mail output sent to me.

If I replace "scheduler" with something weird, I also get a mail with the output which contains the valid options I should choose. So that means for me, that cron is running and the cli_dispatch.phpsh is called correctly.

In TYPO3 Backend the scheduler says the configuration is fine. I can manually start the cron and its doing the job.

So, what else could the reason be...?

EDIT

I figured out that the reason is, that the TYPO3 Scheduler didn't request the correct database. I've an AdditionalConfiguration file where the database name in $GLOBALS['TYPO3_CONF_VARS']['DB']['database'] is changed based on the variable $_SERVER['SERVER_NAME']. But in Scheduler this variable is empty. So I had to delete the AdditionalConfiguration file and everything is working as espected.

The question now is, how can I achieve Scheduler getting the right Database based on Servername?

Answer 1

与其检查服务器变量，不如更好地使用应用程序上下文，该上下文也可以在调用调度程序时进行设置

For others more complete answer:

In .htaccess you set the Application Context of your site based on youtr hostname.

Example:

# Rules to set ApplicationContext based on hostname
RewriteCond %{HTTP_HOST} ^dev\.example\.de$
RewriteRule .? - [E=TYPO3_CONTEXT:Development]
RewriteCond %{HTTP_HOST} ^alpha\.example\.de$
RewriteRule .? - [E=TYPO3_CONTEXT:Production/Staging]
RewriteCond %{HTTP_HOST} ^www\.example\.de$
RewriteRule .? - [E=TYPO3_CONTEXT:Production]

In your AdditionalConfiguration.php you set the DB based on this Context. Example:

if (\TYPO3\CMS\Core\Utility\GeneralUtility::getApplicationContext()->isDevelopment()) {
    $GLOBALS['TYPO3_CONF_VARS']['DB']['database'] = 'typo376_dev';
    $GLOBALS['TYPO3_CONF_VARS']['DB']['username'] = 'typo376_dev_usr';
    $GLOBALS['TYPO3_CONF_VARS']['DB']['password'] = 'somepw';
    $GLOBALS['TYPO3_CONF_VARS']['SYS']['clearCacheSystem'] = '1';
} elseif (\TYPO3\CMS\Core\Utility\GeneralUtility::getApplicationContext() == 'Production/Staging') {
    $GLOBALS['TYPO3_CONF_VARS']['DB']['database'] = 'typo376_alpha';
    $GLOBALS['TYPO3_CONF_VARS']['DB']['username'] = 'typo376_alpha_usr';
    $GLOBALS['TYPO3_CONF_VARS']['DB']['password'] = 'someotherpw';
} else if(\TYPO3\CMS\Core\Utility\GeneralUtility::getApplicationContext() == 'Production') {
    $GLOBALS['TYPO3_CONF_VARS']['DB']['database'] = 'typo376';
    $GLOBALS['TYPO3_CONF_VARS']['DB']['username'] = 'typo376_usr';
    $GLOBALS['TYPO3_CONF_VARS']['DB']['password'] = 'someotherpw';

}

In your cron tab (edit it with crontab -e on your command line) you set the Envroiment Variable before you call the cliscript.

Example:

* * * * * TYPO3_CONTEXT=Production/Staging php /var/www/alpha/beta/gamma/typo3/cli_dispatch.phpsh scheduler
