Possible Bug: Graceful restart of apache 12.5.30 Update #1

[fliegerhermi]

Switching on the graceful restart of apache2 instead of a regular restart as described here: http://kb.odin.com/en/112020 results in the following error in the plesk panel

New configuration files for the Apache web server were not created due to the errors in configuration templates: Can not restart web server: . Detailed error descriptions were sent to you by email. Please resolve the issues and click here to generate broken configuration files once again or here to generate all configuration files. See the details in Configuration Troubleshooter

The detailed email is:

Unable to generate the web server configuration file on the host <mail.xxx.de> because of the following errors:

Template_Exception: Can not restart web server:
file: /opt/psa/admin/plib/Service/Driver/Web/Server/Apache.php
line: 104
code: 0
Please resolve the errors in web server configuration templates and generate the file again.

If you choose the repair option of all config files the following error comes up:

Freshly installed Plesk 12.5 on Debian Jessie. Maybe a bug? I haven't changed anything besides the session_save path in the php ini

If I switch the mysql-config value for graceful restart back to false the reconfiguration of the config works....
Thank you very much for any help.

I can't reproduce this issue on my test Plesk 12.5 server. I have inserted SQL record according to instruction from KB article and restarted Apache without any problem.
Command

# /opt/psa/admin/bin/apache_control_adapter --restart --restart-interval 0 --http-port 80 --https-port 443 --graceful

has been started in CLI also without any errors.

Thank you for your feedback. Have you also setup a new subscription after changing the DB-Entry? That's what I need to do to reproduce. It does not affect existing accounts.

#/opt/psa/admin/bin/apache_control_adapter --restart --restart-interval 0 --http-port 80 --https-port 443 --graceful
is working without error-output, but the config-error persists.

As soon as I switch the graceful restart back to false the configs rebuild without error.

 

[IgorG]

Yes, I have created new subscription without any problem. In database:

mysql> select * from misc where param='restart_apache_gracefully';
+---------------------------+------+
| param | val |
+---------------------------+------+
| restart_apache_gracefully | true |
+---------------------------+------+
1 row in set (0.00 sec)

Well, I don't know. Is it also Jessie? There seem to be quite a few problems with Debian Jessie.
I tried it with a fresh machine and the error came back as soon as the first subscription was created.
I can't file official tickets with my license so I will have to wait until somebody else picks it up.

Too bad everything is encrypted. I am wondering what opt/psa/admin/plib/Service/Driver/Web/Server/Apache.php Line 104 looks like.

 

[IgorG]

I have CentOS 6.6.
Actually we have changed nothing that can affect Plesk operation with graceful restart enabled.
I can assume that this behaviour may be on Debian Jessie. I suggest you buy per-incident support for investigation this issue directly on your server. More detail you can find here - http://talk.plesk.com/threads/impor...ution-for-the-existing-issue-question.334123/

I can confirm this bug. I have the same problem - also on Jessie.

There is a fix now posted in the knowledge base. It solves the problem for me:
