Resolved Apache Server Settings Breaking Apache

[nolyoly]

Hello all, when trying to enable apache modules I'm having problems where the spiining disk on the apply button locks up and nothing happens. I tried enabling the PHP7.0 module and waited about 5 mins. It broke apache and I cant start it now. It showed the PHP7.0 module checkbox checked after reloading the page, so I tried to disable it and got this error message.

I'm running Ubuntu 16.04 and Plesk Onyx 17.5.3.

Error: START httpd_modules_ctl --disable authn_core,php7.0 resource(s) deleted resource(s) deleted resource(s) deleted resource(s) deleted resource(s) deleted resource(s) deleted websrvmng: /opt/psa/admin/sbin/apache_control_adapter execution failed: Aug 08 19:37:48 odin apache2[2746]: * The apache2 configtest failed.

I have no idea what I did wrong or how to fix this. It seems I have nothing but problems since I started trying to use Plesk. I'm getting very close to moving back to cPanel.

If anyone can help me out I'd appreciate it a ton. I love the Plesk software, but it's just been nothing but problems since the start.

Also, when trying to start apache from the services page I get this error now.

Unable to start service: Unable to manage service by apache_control_adapter: ('start', 'web'). Error: Aug 08 19:44:38 odin apache2[5960]: * The apache2 configtest failed.

Hi nolyoly,

you recently upgraded your apache - webserver from version <=2.2 to a version >=2.4 and didn't change necessary definitions, which results in a non-working apache - webserver:

Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration

Pls. read and inform yourself about the most important chnges at:

=> Upgrading to 2.4 from 2.2 - Apache HTTP Server Version 2.4

Pls. check for

Order deny,allow
Deny from all

and change it to:

Require all denied

Pls. check for

Order allow,deny
Allow from all

and change it to:

Require all granted

... pls. look for other changes at the above mentioned link.​

You might consider to search for related/current settings, with find - commands like:

find /usr/local/psa/admin/conf/templates -type f -name "*.php" -exec grep --color -Hni "Order" {} \;

or/and

find /etc/apache2 -type f -name "*.conf" -exec grep --color -Hni "Order" {} \;

or/and

find /var/www/vhosts/system/*/conf -type f -name "*.conf" -exec grep --color -Hni "Order" {} \;

I didn't upgrade it. All I did was try enabling Apache modules through the Plesk panel. So I couldn't have misspelled anything. I didn't type anything. Just clicked the check boxes.

And if you do so, plesk repair brings back all this "Order allow,deny" things.
Ubuntu 16.x comes with Apache 2.4.x per default. (apache2 -v == Apache/2.4.18 (Ubuntu))

Hi LTUser,

And if you do so, plesk repair brings back all this "Order allow,deny" things.

Actually I couldn't reproduce the issue, that the Plesk Repair Utility rewrites the depending configuration files with => "Order allow,deny" things. The actual templates use for example:

<?php if ($VAR->server->webserver->apache->useRequireOption): ?>
    Require all granted
<?php endif; ?>
    Order allow,deny
    Allow from all

... so that the => "Order allow,deny" things depend on your current used apache version.

But I would assume, that you probably use old or custom webserver configuration templates, which might be the root cause of such a described issue. Would you mind posting the results of:

find /usr/local/psa/admin/conf/templates -type f -name "*.php" -exec grep --color -Hni "Order" {} \;

and could you pls. as well be so kind to add the corresponding *.php - files as attachments at your next post, which you found with the above find - commands?​

I think i got the error...
The "useRequireOption" isn't set always the right way and "Order Allow / deny" is sometimes also set when the Apache version is "2.4.18". So i removed all "Order..." i found in the templates in "/usr/local/psa/admin/conf/templates/*" and change it to "require..." now the error is gone. (Sorry for my bad english )
