This tutorial explains How to get up and running trytond with Nginx as a reverse proxy and trytond as a backend with supervisord + uwsgi configurations.
- The package tools as nginx, supervisord and uwsgi would be explain with a debian distribution but should be very similar with other linux distributions.
- The domain as example would be
example.tryton.org - The installation of trytond would not be cover on this How to. pypi installation it’s the most probably installation to a production enviroment so that would be expect to set up a uwsgi configuration.
- IP 192.168.1.1 it’s where backend trytond is running.
- PORT 8000 it’s where backend trytond port is running.
Set Up nginx
Install nginx package
apt install nginx
Set up a new virtualhost
- Create a new file called
example.tryton.org.confat/etc/nginx/sites-available.
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name example.tryton.org;
ssl_certificate /etc/letsencrypt/live/example.tryton.org/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.tryton.org/privkey.pem;
ssl_protocols TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers on;
ssl_verify_client optional_no_ca;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://192.168.1.1:8000;
}
}
server {
listen 80;
listen [::]:80;
server_name example.tryton.org;
return 301 https://example.tryton.org$request_uri;
}
- Create a symlink from sites-available to sites-enabled.
cd /etc/nginx/sites-enabled
ln -svf /etc/nginx/sites-available/example.tryton.org.conf .
Reload nginx service
- Verify that yours configuration are OK.
nginx -t
- Reload nginx service
service nginx reload
Set Up trytond backend
Installation of trytond would not be cover on this How to, but the idea is to run a production enviroment, so pip installation would be expected.
uWSGI
The uWSGI project aims at developing a full stack for building hosting services.
Application servers (for various programming languages and protocols), proxies, process managers and monitors are all implemented using a common api and a common configuration style.
Install uwsgi
apt install uwsgi
Create a uwsgi configuration
[uwsgi]
http-socket=0.0.0.0:8000
master=true
plugins=python3
wsgi=trytond.application:app
cheaper=4
processes=16
threads=16
Note: If we set up our trytond inside a virtualenv we should add this line to the uwsgi.conf
virtualenv=/path/to/env
Supervisord
Supervisor is a client/server system that allows its users to control a number of processes on UNIX-like operating systems.
Installation
apt install supervisor
Configuration
Create a new config file under /etc/supervisor/conf.d/ called supervisor_tryton.conf. The contents of the file should be something like
[program:trytond]
command=uwsgi --ini /path/to/uwsgi_trytond.conf
autostart=true
autorestart=true
startretries=3
numprocs=1
stopwaitsecs=10
stopsignal=INT
redirect_stderr=true
environment=
TRYTOND_DATABASE_URI="postgresql://db_username:db_password@db_hostname:db_port"
TRYTOND_LOGGING_CONFIG="/path/to/trytond_tog.conf",
PYTHONOPTIMIZE="1"
Update supervisor
You need to update supervisord so reads the new configuration
supervisorctl update
start trytond daemon with supervisord
supervisorctl start trytond
Conclusion
That’s it!
You should go to https://example.tryton.org and tryton set up should be up and running!
Enjoy!
