Add the following line to crontab and save
*/5 * * * * /home/blaise/blaise_server/venv/bin/python /home/blaise/blaise_server/price_cron.py >/dev/null 2>&1
The recommended configuration is to run the server behind nginx, which will act as a reverse proxy
Next, we'll define a systemd service unit
/etc/systemd/system/blaise@.service
[Unit]
Description=Blaise Server
After=network.target
[Service]
Type=simple
User=blaise
Group=www-data
EnvironmentFile=/home/blaise/blaise_server/.env
WorkingDirectory=/home/blaise/blaise_server
ExecStart=/home/blaise/blaise_server/venv/bin/python blaise_server.py --host 127.0.0.1 --port %i --log-file /tmp/blaise%i.log
Restart=on-failure
[Install]
WantedBy=multi-user.target
Enable this service and start it, ensure all is working as expected
sudo systemctl enable blaise@4443
sudo systemctl start blaise@4443
sudo systemctl status blaise@4443
Next, configure nginx to proxy requests to this server
/etc/nginx/sites-available/blaiseapi.appditto.com
upstream blaise_nodes {
least_conn;
server 127.0.0.1:4443;
}
server {
server_name blaiseapi.appditto.com;
location / {
proxy_pass http://blaise_nodes;
proxy_redirect off;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Host $server_name;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
Enable this configuration and restart nginx
sudo ln -s /etc/nginx/sites-available/blaiseapi.appditto.com /etc/nginx/sites-enabled/blaiseapi.appditto.com
sudo service nginx restart
sudo add-apt-repository ppa:certbot/certbot
sudo apt update
sudo apt install python-certbot-nginx
sudo certbot --nginx
