Deploy¶

There are several options for sanic server deployment:

Standalone server
Running a pool of backend servers behind of nginx, HAProxy or other reverse proxy server

Every method has own benefits and disadvantages.

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.

But this way requires more complex configuration.

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

Configuration file for nginx¶

upstream aiohttp {
    server 127.0.0.1:5171 fail_timeout=0;
    server 127.0.0.1:5172 fail_timeout=0;
}

server {
    listen 5170;
    client_max_body_size 4G;
    server_name luna_accounts;

    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/
