Nginx 502 BAD GATEWAY

B

Bourgois_Christophe

Basic Pleskian
Dear Parallels team,

I'm facing a problem discussed in lot of threads but no solution works for me.

When I'm calling plesk api to create a new domain, I've got a Nginx 502 BAD GATEWAY error.

The logs indicates :
2014/12/17 18:50:25 [error] 21921#0: *5 upstream prematurely closed connection while reading response header from upstream, client: x.x.x.x, server: example.com, request: "POST /user/my_blogs HTTP/1.1", upstream: "http://x.x.x.x:7080/user/my_blogs", host: "example.com", referrer: "http://example.com/user/my_blogs"

I suppose that while nginx is loading the page from apache, plesk is restarting apache and so upstream is closed.

What is the solution to avoid this error ?

Thanks a lot
 
I also tried to change restart_apache_interval value to 30 seconds, and restart apache, but I've got the same problem after 15 seconds, so I'm not sure restart_apache_interval is used, or maybe I need to do another thing.
 
Hello,

I just worked a little more deeper on this problem, and here is what I can say.

This values are in misc table :
restart_apache_gracefully | true
restart_apache_interval | 30

But when I call plesk api to create a new domain, I still have got a Nginx 502 BAD GATEWAY error.

So I looked in the logs and here is what I have when I type:
tail -f /var/log/apache2/error.log /var/log/apache2/access.log /var/log/nginx/access.log /var/log/nginx/error.log

Hi Bourgois_Christophe,

to solve your python issue, you might use:

Example for Debian/Ubuntu:

apt-get remove libapache2-mod-python libapache2-mod-wsgi
apt-get build-dep libapache2-mod-python libapache2-mod-wsgi
​

The warnings about your certificates missmatch are irrelevant, but you could adjust the server certificates "commonName" - settings, if this annoys you, when creating a new certificate. The "commonName" should equal the FQDN ( Fully Qualified Domain Name - please use "hostname -f" for it ) of your server.
 
Thanks, now there is no python error but when I call plesk api to create a new domain, I still have got a Nginx 502 BAD GATEWAY error.

Here are the logs:

Hi Bourgois_Christophe,

please be aware, that the standard apache and nginx error-logs have got nothing to do with the Plesk Control Panel - logs. Plesk uses his own nginx server, independent from your webservers on your server.


Please use the correct error - logs, to point to possible issues/problems/failures.


You could as well switch to a debug log level, if the standard configuration does not show sufficient informations in the Plesk Control Panel logs:

Go to "/usr/local/psa/admin/conf/" and copy the sample "panel.ini.sample" to "panel.ini".
Afterwards, please edit the "panel.ini" to your needs.​
 
Dear UFHH01, thanks for your responses.

I put the line
Code: 
filter.priority = 7
in /usr/local/psa/admin/conf/panel.ini
and then I restart:
Code: 
/etc/init.d/psa restart

After that I call again Api to create a new domain and get 502 nginx error

Here are the logs but I can't see any error, maybe I look in the bad log files ?:
tail -f /var/log/apache2/error.log /var/log/sw-cp-server/error_log /var/log/sw-cp-server/sw-engine.log /usr/local/psa/admin/logs/panel.log /var/log/nginx/error.log

Hi Bourgois_Christophe,

we are getting closer... ^^

If you open the domain "monblogtest2015-8.fr" with your internet browser, you get the error 502 - correct? Your former description was pointing to a Plesk Control Panel issue and not to a domain specific issue.

Your domain specific logs for "monblogtest2015-8.fr" are located at: /var/www/vhosts/system/monblogtest2015-8.fr/logs/*.
Please make sure, that if you use apache and FastCGI, to restart php5-fpm as well in order to read the new FastCGI - configuration for this domain as well and to be sure, that the domain specific socket is created. ( service php5-fpm restart ).
If you use nginx as well, your domain specific webserver settings might need additional rewrite rules, depending on your domain content, because nginx can't read rewrite rules from apache - htaccess - files.
 
Dear UFHH01, thanks a lot for your replies !

I did the mysql configuration adjustments because it's good for velocity, but it changes nothing.

My problem is not that I receive an empty reply from server, related to mysqld.

My problem is that:
  • my page send an xml packet to create the domain on plesk server,
  • the domain is really created on parallels plesk panel,
  • but on client side, I don't receive xml packet to know the result of the request, instead of that I get the 502 nginx error.
 
Do you have an idea on how to debug more deeper this problem ?
The only error I can see is on my web client : 502 nginx, I see no error on the server...
 
Hi Bourgois_Christophe,

I would increase the "max_execution_time", "max_input_time" in your PHP.ini's, to see if this is the cause. I would suggest a maximum setting of 600 seconds.
 
Thanks for this informations, on /usr/local/psa/admin/conf/php.ini it's already set to 600 seconds.
I set this in /etc/php5/apache2/php.ini and also display_errors to On to have more informations.

I still have the errors but looking forward the log I founded two intersting lines:
