all sites point to default vhost from time to time

So you have phpbb installed on your server? or can you install it? If phpbb does not redirect to port 7080 then sure its resolved ...

If you don't mind please let me know how it all goes ...
 
Hello,

has the official fix been issued for this bug yet?

Maybe my investigation can toss more light into what could be wrong...

---------------------------------------------------------------
PRODUCT, VERSION, MICROUPDATE, OPERATING SYSTEM, ARCHITECTURE
Plesk Linux, 11.0.9 (upg. 10.4.4), #7, Debian 6.0, x64


PROBLEM DESCRIPTION
= = = = = = = = = =
"After some time all websites point to Default Page/Site or Nginx 404 error"

After several hours of frustrating manual investigation and log comparison,
I think I found a trace of circumstances when it comes to this issues.
When Nginx is active and we install an AppVault application in Plesk panel,
the Plesk system seems to "loose"/delete(?) all domain vhosts configuration
files, and then it goes to Nginx 404 Error (if Nginx is active) or to
Default Page/Site (if only Apache runs).

We had the following situation - first the Nginx was active. After the AppVault
App was installed, all sites got "Nginx - Error 404". We deactivated the Nginx
via Plesk, and the server was back on Apache only.
Several hours later came another AppVault installation and this brought us to
"Default page/site" issue. The only thing that helped then was command-line
vhosts regeneration.

I hope this helps developers to pinpoint and solve this issue!!


STEPS TO REPRODUCE
= = = = = = = = =
Situation (A) - with Nginx
-> upgrading already running and configured 10.4.4 system to 11.X (this step is important, I guess)
-> installing & activating Nginx via Plesk Installer (GUI)
-> installing an Application from AppVault (see ADDITIONAL INFO part for more clues from log)
==> all domains go "Nginx - Error 404"
-> deactivate Nginx in Plesk (Server Management > Services Management)

Situation (B) - without Nginx
-> AFTER the Nginx has been deactivated in Situation (A)
-> installing an Application from AppVault (see ADDITIONAL INFO part for more clues from log)
==> all domains go "Plesk/Apache Default site"


ACTUAL RESULT
= = = = = = =
Plesk (most probably) deletes all vhosts files and the :
(A) Nginx+Apache -> visiting any domain displays "Nginx 404 Error"
(B) Apache only -> visiting any domain displays "Plesk/Apache Default site"


EXPECTED RESULT
= = = = = = = =
to display domains normally :)

=======> We tried to restart both, Nginx and Apache service, but none helped. Finally, disabling Nginx in Plesk Panel helped, but I suppose this acctually helped because it triggered the vhosts configs rebuilding process.

autoupdate caused problem

I have had a very similar problem.

Last night there was an autoupdate to Plesk 11 after that all the sites on the server went down (just showing the default page). The websites came back after resaving the hosting settings for each domain.

I have just had down time on that server with failed hard drive and had to reinstall, this extra bit of downtime was very unwelcome.

Please fix ASAP. (turned off autoupdates now, they can't be trusted if this is the result)
 
Guys, developers can't reproduce this issue. Could you please send me in PM login credentials for your server? I will forward it to developers and they will check this issue directly on your server.

OK, thanks for your reply. I will prepare the credentials for you.

In the meantime, as temporary precaution, we disabled the APS Application Installer option for all domains...

I would love to, but since I can easily resolve that problem with /usr/local/psa/admin/sbin/httpdmng --reconfigure-all I can't risk that much down time as the developers check it out ... :)

NB: So far I have noticed that its quite common with Nginx enabled, if Apache fails to restart, if MySQL queries timeout pretty fast that /usr/local/psa/admin/sbin/httpdmng --reconfigure-all does not complete execution.

I think its something we might have control over other than a plesk problem ...

What do you mean by that? That reconfiguration takes so long that a MySQL connection is closed due to a timeout? How long does it take in your case?
 
This is becoming so often with one of my servers showing plesk default page when opening webmail.domain.com especially with Nginx enabled.

On the same server i started nginx recently and after some time again 404 nginx default pages. I fixed problem with just stoping nginx service (there was no need to reconfigure files, pages were working).


Nginx error log is full of errors, i don't want to copy everything, if needed, i can send again PM with the login credentials for server.

dpkg is Debian/Ubuntu utility for manage package system. Use the same utility for rpm-based OSes - rpm with corresponding options.

I forgot to mention that we have new server where we installed clean Plesk 11 (no upgrade) and nginx is working there since first day and there are no problems so far, so i suppose this problem came along with the upgrade from 10.4.4 to 11.0.x. If needed, developers can check both servers if that will help with fixing this problem.
