![¿Cómo puedo configurar varias aplicaciones Django usando Supervisor (incluidos Gunicorn y Nginx)? bind() a [::]:8090 falló (98: dirección ya en uso)](https://rvso.com/image/769178/%C2%BFC%C3%B3mo%20puedo%20configurar%20varias%20aplicaciones%20Django%20usando%20Supervisor%20(incluidos%20Gunicorn%20y%20Nginx)%3F%20bind()%20a%20%5B%3A%3A%5D%3A8090%20fall%C3%B3%20(98%3A%20direcci%C3%B3n%20ya%20en%20uso).png)
Ya implementé una aplicación Django/Wagtail usando Supervisor, Gunicorn y Nginx (en Debian Buster), así que puedo acceder a ella conhttp://xx.xxx.xxx.xxx:8090.
/etc/nginx/sites-available/cms
server {
server_name xx.xxx.xxx.xxx;
listen 8090;
listen [::]:8090 ipv6only=on;
error_log /home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/gunicorn-error.log;
access_log /home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/gunicorn-access.log;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /home/www.mysite.com/www/my-site/cms/admin_panel;
}
location /media/ {
root /home/www.mysite.com/www/my-site/cms/admin_panel;
}
location / {
include proxy_params;
proxy_pass http://unix:/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/run/gunicorn.sock;
}
}
/etc/supervisor/conf.d/guni-mysite-admin.conf
[program:guni-mysite-admin]
command=/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/bin/gunicorn admin_panel.wsgi:application --config /home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/etc/gunicorn/conf.py
user=www.mysite.com
autostart=true
autorestart=true
/etc/supervisor/conf.d/nginx-mysite-admin.conf
[program:nginx-mysite-admin]
command=/usr/sbin/nginx -g "daemon off;"
autostart=true
autorestart=true
stderr_logfile=/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/nginx-error.log
stdout_logfile=/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/nginx-access.log
stderr_logfile_maxbytes=2MB
stdout_logfile_maxbytes=2MB
/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/etc/gunicorn/conf.py
workers = 3
keepalive = 5
user = 'www.mysite.com'
proc_name = 'admin_panel'
loglevel = 'error'
errorlog = '/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/gunicorn-error.log'
accesslog = '/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/var/log/gunicorn-access.log'
bind = 'unix:/home/www.mysite.com/.local/share/virtualenvs/cms-WqsZ9qOt/run/gunicorn.sock'
raw_env = ['DJANGO_SETTINGS_MODULE=admin_panel.settings.production']
pythonpath = '/home/www.mysite.com/www/mysite/cms/admin_panel'
Ahora agregué 2 aplicaciones Django más de la misma manera. Desafortunadamente el supervisor no puede mencionarlos. A veces se ejecuta 1 de cada 3, pero la mayoría de las veces ninguno funciona. En caso de que funcione, crea 3 procesos (no sé si así es como se supone que debe ser).
$ sudo lsof -i:8090
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 3631 root 16u IPv4 961301189 0t0 TCP *:8090 (LISTEN)
nginx 3631 root 17u IPv6 961301190 0t0 TCP *:8090 (LISTEN)
nginx 3632 www-data 16u IPv4 961301189 0t0 TCP *:8090 (LISTEN)
nginx 3632 www-data 17u IPv6 961301190 0t0 TCP *:8090 (LISTEN)
nginx 3633 www-data 16u IPv4 961301189 0t0 TCP *:8090 (LISTEN)
nginx 3633 www-data 17u IPv6 961301190 0t0 TCP *:8090 (LISTEN)
El registro de errores de Nginx proporciona98: Dirección ya en uso, incluso en el puerto 81 (lo tomó como puerto predeterminado porque Apache usa el 80), que no se usa. Apache no debería ser el problema, porque no funciona, incluso cuando Apache está apagado.

Parece que nginx se queja solo de la dirección IPV6. ¿Necesitas ipv6? Si no lo hace, eliminar los bloques de escucha para ipv6 hará que nginx se inicie correctamente solo en ipv4. Si SÍ necesita oyentes IPV6 en nginx, puede hacer lo siguiente
fuser -k 8090/tcp
Esto eliminará el puerto de retención PID 8090. Haga lo mismo con el resto de los puertos que necesite. Un enfoque más severo sería eliminar nginx por completo (suponiendo que sea el que mantiene abiertos los puertos)
pkill -f nginx & wait $!
service nginx restart
