uwsgi_bind
The `uwsgi_bind` directive sets the address and port that NGINX will use to communicate with uWSGI servers.
Description
The uwsgi_bind directive is part of the NGINX configuration for managing connections to uWSGI servers, which are commonly used for serving Python applications. This directive allows you to specify the IP address and port (or a Unix socket) where NGINX should send requests to the uWSGI backend. By default, uWSGI listens on 127.0.0.1:8000, but this directive lets you customize that address based on your infrastructure needs.
The directive accepts one or two parameters. The first parameter is the address for the uWSGI server, while the optional second parameter can specify the port if you're using TCP sockets. If a Unix domain socket is specified, the address will be the path to that socket. This feature allows for efficient communication as it bypasses the TCP stack completely. The uwsgi_bind directive can be used in various contexts including http, server, and location, making it flexible for configuration across different levels of the NGINX setup.
When multiple uwsgi_bind directives are defined, NGINX will listen on all specified addresses to facilitate scalability and load balancing among multiple uWSGI processes or servers. Make sure to match the connection settings properly with your uWSGI application configuration to avoid connectivity issues, particularly regarding socket permissions.
Config Example
location / {
include uwsgi_params;
uwsgi_bind 127.0.0.1:8000;
uwsgi_pass myapp;
}Ensure that the uWSGI server is correctly configured to listen on the specified address and port.
Be cautious about permissions when using Unix domain sockets; ensure NGINX has access rights to the socket file.
If using multiple uwsgi_bind directives, verify that they do not conflict with each other.
