Resolved Web Server's Default Page after updates

stevland

stevland

Basic Pleskian
Server operating system version
CentOS Linux 7.9.2009 (Core)
Plesk version and microupdate number
Plesk Obsidian Version 18.0.53 Update #2
I installed the latest minor update about an hour ago

Every site that I host is now displaying the "Web Server's Default Page" rather than its homepage. But the files (index.php, etc.) are intact.

Edit: There are no index.html files overriding index.php ones, etc.
 
I'm running
Code: 
plesk repair fs -verbose
and seeing the following:

Code: 
One or more files or directories in the root directory of the domain
  'coverac.ca' are either writable by anyone or neither readable nor
  writable by the owner. Such permissions are insecure and may result
  in or indicate a security breach
 
It's running through this for each of the domains I host and failing each time.

Code: 
  There are incorrect permissions on some items in the system
  directory for the domain '[redacted]' .................... [ERROR]
    - Failed to stat
      /var/www/vhosts/system/[redacted]/conf/nginx.conf: No
      such file or directory

      Failed to open safely
      /var/www/vhosts/system/[redacted]/conf/nginx.conf: No
      such file or directory
 
After running
Code: 
plesk repair fs
and
Code: 
plesk repair web
the situation has changed slightly. All secure domains result in a
Code: 
ERR_SSL_PROTOCOL_ERROR
, while non-encrypted domains still show the Web Server's Default Page.
 
This is bizzare. I'm showing one example but it seems to be consistent with all of the domains that I host:

Code: 
# plesk repair web mineralssouth.com

From one of your posts above I derive that at least in one domain or in one mutual php.ini file the upload_max_filesize is set to 0, which seems to be an issue for Apache. I have not encountered a similar situation before. My next step would be to check with
grep upload_max_filesize /opt/plesk/php/*/etc/*.ini
what the general settings are in the PHP ini files. These should default to 2M. Then please also check if you have a php section in /usr/local/psa/admin/conf/panel.ini. If so, what values does it have? If these are not actively needed, remove the php section completely.

Code: 
[php]
settings.performance.upload_max_filesize[]=128M


[webserver]
nginxClientMaxBodySize = 128M

(The php and webserver values would have been added by myself at some point when I was trying to figure out how to overcome some limitation. I have now removed them and rebooted the server, but nothing has changed.)
 
I will not be able to solve this here without looking into the server. Please introduce the issue with a reference to the thread to Plesk support, so that a support engineer can check it and solve it on your server.

Hi Peter, that's exactly what I ended up doing. Gilson helped me right away. Super pleased with the service.

I'll post his findings here in case it helps anyone in the future:
For starters, I went through the logs but did not find a lot of things.
Then I noticed through nginx -t that the configuration syntax was OK but nginx itself was dead.

Jul 01 12:24:00 www.redacted.com systemd[1]: Starting Startup script for nginx service...
Jul 01 12:24:00 www.redacted.com sh[28839]: Not starting nginx as it is disabled in Plesk. Run 'plesk sbin nginxmng -e' to enable nginx in Plesk.

Thus I have disabled and enabled nginx:

[root@www ~]# plesk sbin nginxmng -d
[root@www ~]# plesk sbin nginxmng -e

And voilà, most of the time with this combination (syntax ok + nginx dead) this resolves the issue.
