Deploy¶

There are several options for sanic server deployment:

Standalone server
Running a pool of backend servers behind Nginx, HAProxy or another reverse proxy server. Several instances of sanic can be managed with systemd (Nginx+systemd)

Running sanic servers behind nginx makes several advantages:

At first, Nginx is the perfect frontend server. It may prevent many attacks based on malformed HTTP protocol etc.
Second, running several sanic instances behind nginx allows to utilize all CPU cores.
Third, nginx serves static files much faster than built-in sanic static file support.

Template configuration files for nginx are presented below. For more information, you can visit sanic.readthedocs.io.

Configuration file for Nginx¶

upstream aiohttp {
    server 127.0.0.1:5141 fail_timeout=0;
    server 127.0.0.1:5142 fail_timeout=0;
}

server {
    listen 5140;
    client_max_body_size 4G;

    server_name 127.0.0.1;

    location / {
      proxy_set_header Host $http_host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_redirect off;
      proxy_buffering off;
      proxy_pass http://aiohttp;
    }
}

Configuration file for systemd¶

Config should be located in directory /etc/systemd/system/
