Gunicorn
Configuration file: /var/www/apps/sampleapp/guniconf.py

Nginx
Default settings: /etc/nginx/sites-enabled/000-default.conf
server {
listen 80 default_server;
root /var/www;
index index.php index.html index.htm;
location / {

Add the following information to this file

+ proxy_set_header Host $host;
+ proxy_set_header X-Real-IP $remote_addr;
+ proxy_redirect off;
+
+ proxy_pass http://my_app_server;
+ }
}
Reboot once
$ sudo service nginx restart
After restarting and starting Gunicorn, check if it can be accessed properly.
Supervisor
Supervisor ** daemonizes a process **. Install with the package manager of each distribution.
Configuration file: /etc/supervisor/conf.d/my_app.conf
[program:my_app]
command = /home/***/.pyenv/shims/gunicorn sample:app --config /var/www/apps/sampleapp/guniconf.py
directory = /var/www/apps/sampleapp/
user = root
Write gunicorn commands with ** absolute path **. Please rewrite each
You need to load the config file into supervisor
.
$ supervisorctl reread
$ supervisorctl update
$ supervisorctl start my_app
This should work for the time being! !!
