Error when testing astakos

[maximel...@gmail.com]

Hi all , i'm trying to install synnefo on two nodes and i actually follow the administrator's intallation guide 0.19 (on Debian Jessie). When testing astakos ,my browser show me this : ''502 proxy error Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET Reason: Error reading from remote server /astakos . Apache/2.4.10 (Debian) Server at debian.myowncloud.tg Port 443 ''


Above all this , it seems like apache failed to make connection with gunicorn. Before testing astakos, i restart apache and gunicorn.When i verify if gunicorn process is loaded, i get this output :


root@debian:~# ps -ef | grep gunicorn root 23920 1 6 10:48 ? synnefo 23971 23920 0 10:48 ? synnefo 23972 23920 0 10:48 ? synnefo 23974 23920 0 10:48 ? synnefo 23975 23920 0 10:48 ? synnefo 23976 23920 0 10:48 ? root root 23977 23920 0 10:48 ? 00:00:00 gunicorn: master [synnefo] 00:00:00 gunicorn: worker [synnefo] 00:00:00 gunicorn: worker [synnefo] 00:00:00 gunicorn: worker [synnefo] 00:00:00 gunicorn: worker [synnefo] 00:00:00 gunicorn: worker [synnefo] 00:00:00 gunicorn: worker [synnefo] 23979 8716 0 10:48 pts/2 00:00:00 grep gunicorn root 23980 23920 0 10:48 ?

The gunicorn status show this :

root@debian:~# service gunicorn status

00:00:00 gunicorn: worker [synnefo] ● gunicorn.service - (null) Loaded: loaded (/etc/init.d/gunicorn) Active: active (exited) since jeu. 2017-09-14 10:10:43 CEST; 18min ago Process: 12658 ExecStop=/etc/init.d/gunicorn stop (code=exited, status=0/SUCCESS) Process: 12665 ExecStart=/etc/init.d/gunicorn start (code=exited, status=0/SUCCESS) sept. 14 10:10:43 debian.myowncloud.tg gunicorn[12665]: Starting Gunicorn workers: [synnefo]. sept. 14 10:10:43 debian.myowncloud.tg systemd[1]: Started (null).


After getting the '' 502 proxy error '', i run this command again :

root@debian:~# ps -ef | grep gunicorn

i didn't seen any output , it seems like gunicorn process is dead.

Here are respectively the differents outputs of gunicorn and apache log file.


root@debian:~# tail -f /var/log/synnefo/gunicorn.log
