Question Plesk shows white Screen nginx not Starting

[Dennis S]

Hello,

i have a big problem with my CentOS 7 Server with Plesk 12.5 on it. Since a few days i cannot login to plesk because i only get a white screen. Now i reed some threads and try somethings out and now my complete website is not showing up.

when i try to start nginx it shows this:

[root@unibuy nginx]# sudo /etc/init.d/nginx start
Starting nginx (via systemctl): Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

Hi Dennis S,

first pls. be informed, that Pleks uses it's very own webserver called "sw-cp-server". A restart command for this service is done with the command:

service sw-cp-server restart
or use
service psa restart​

Pls. post corresponding entries from your log - files, if you would like help from people willing to help you.

Plesk for Linux services logs and configuration files ( KB - article: 111 283 )​

Sometimes, it is as well a good idea to change the log - level, to get more informations in psa - log - files:

How to enable/disable debug logging in Plesk 11.5 and up? ( KB - article 120 101 )​

Second, is there a reason, why you use the start - script as starting command for your service "nginx"? You should use the command "service nginx restart", or "systemctl start nginx", in case that you would like to restart this service.


Third, pls. consider to investigate the shown reason(s) from "systemctl status YOURSERVICENAME.service" and "journalctl -xe", when you experience issues with your start - scripts. In your case it shows:

/usr/bin/test: fehlendes Argument hinter ââyesââ
​

... which points to a manual edit ( copy&paste ) of your start - script, with invisible formats ( maybe you copied something from a forum, which uses HTML - formats ?!?), or a non-binary upload of your start - script to your server. Pls. try to remember as well, WHAT you manually edited on your server and HOW and consider to provide these informations in case of any issue(s)!

Hello and first i want to say sorry for my bad english i am german...

so to 2nd. i do try to start it manualy because i read so much forums today to get plesk interface running. And yes i do change some script files on server but now i dont know which one most of them was for a timeout settings.. since i do this, my website is still not showing.

The Site is unibuy.de and plesk will be on 8443 on that domain...

I need to know how can i fix that problem without resetting the complete server

 

[Dennis S]

OK,

so now ive lookt at my chronic and try to figure out what files i changed. Now i got another problem.

Plesk Interface still not working but now in my Browser it shows:

504 Gateway Time-out
nginx

and my domain http://unibuy.de/ shows the Default Parallels Plesk Page. Im sure that in the folder /var/www/vhosts/unibuy.de/httpdocs are my shopfiles but the domain show plesk default page.

 

[Dennis S]

1st of all its important to get my shop back on unibuy.de - where can i search to fix this problem?

 

[Bitpalast]

Have you tried
#plesk repair web
?

 

[Dennis S]

So i try plesk repair web unibuy.de
and it gives no response
..

[root@unibuy nginx]# plesk repair web unibuy.de
<- cursor blinkin here and nothing happend

 

[Bitpalast]

#plesk repair web unibuy.de
will restore the default configuration for the unibuy.de-subscription and is a good guess to fix the issue, unless you have applied individual configuration changes to Apache or Ningx behavior that could interfere with Plesk defaults.

 

[Dennis S]

[root@unibuy nginx]# plesk repair web unibuy.de
<- cursor blinkin here and nothing happend

 

[Bitpalast]

Plesk repair normally works like a charm. I've only seen Plesk repair stuck in one case. You may need to do this:

[Dennis S]

ok, i will try to do this and then i give a reply

 

[Dennis S]
