Detailed introduction to the integration and use of Nginx server's native modules and third-party plug-ins.

Nginx server is a high-performance web server software with very powerful scalability and supports the integration of native modules and third-party plug-ins. This article will introduce in detail the integration and use of the Nginx server's native modules and third-party plug-ins, and attach code examples to help readers better understand and apply them.

1. Nginx native module

Nginx’s native module refers to the functional module officially developed and maintained by Nginx, including core module, HTTP module, mail module, etc. These modules can be enabled or disabled through configuration directives in the Nginx configuration file.

1. Core module

The core module is the basic module of the Nginx server, including core functions and basic configuration instructions. For example, the events module is used to process connection requests and event drivers, and the http module is used to process HTTP protocol requests, etc.

2. HTTP module

The HTTP module provides functions for processing HTTP requests, including HTTP proxy, load balancing, caching, reverse proxy, etc. Through configuration instructions, the behavior of the HTTP module can be flexibly configured. The following is a simple HTTP module configuration example:

http {
    server {
        listen 80;
        server_name example.com;
        location / {
            root /path/to/website;
            index index.html;
        }
    }
}

In the above configuration example, the listen directive is used to specify the listening port, the server_name directive is used to specify the server name, and the location directive is used to specify the URL path matching rules and correspondence. processing logic.

3. mail module

The mail module provides functions for processing mail services, such as SMTP proxy, POP3 proxy, etc. The mail module can be enabled or disabled via configuration directives. The following is a simple mail module configuration example:

mail {
    server {
        listen 25;
        protocol smtp;
        server_name mail.example.com;
        auth_http localhost:80/auth.php;
    }
}

In the above configuration example, the listen directive is used to specify the listening port, the protocol directive is used to specify the protocol type, the server_name directive is used to specify the server name, and the auth_http directive is used on the specified authentication interface.

2. Third-party plug-ins

In addition to native modules, Nginx also supports the integration of third-party plug-ins. Third-party plug-ins can extend the functions of Nginx, such as adding SSL support, adding HTTP2 support, etc. The following is a configuration example using a third-party plug-in:

http {
    server {
        listen 443 ssl http2;
        server_name example.com;
        ssl_certificate /path/to/cert.pem;
        ssl_certificate_key /path/to/key.pem;
    }
}

In the above configuration example, the ssl directive is used to enable SSL support, the http2 directive is used to enable HTTP2 support, the ssl_certificate directive is used to specify the path to the SSL certificate, ssl_certificate_key Directive is used to specify the private key path of the SSL certificate.

3. Code Example

The following is a complete Nginx server configuration example, including the integration of native modules and third-party plug-ins:

worker_processes 1;

events {
    worker_connections 1024;
}

http {
    include mime.types;
    default_type application/octet-stream;
    sendfile on;
    keepalive_timeout 65;

    server {
        listen 80;
        server_name example.com;
        
        location / {
            root /path/to/website;
            index index.html;
        }
    }

    server {
        listen 443 ssl http2;
        server_name example.com;
        ssl_certificate /path/to/cert.pem;
        ssl_certificate_key /path/to/key.pem;

        location / {
            root /path/to/website;
            index index.html;
        }
    }
}

In the above configuration example, the worker_processes directive Used to specify the number of Nginx processes, the events directive is used to set the number of concurrent connections, the http directive is used to configure the HTTP module, the include directive is used to introduce the mime.types file, the default_type directive is used to set the default content type, and the sendfile directive is used to enable Efficient file transfer function, the keepalive_timeout directive is used to set the long connection timeout.

Through the above introduction, we can understand the integration and use of the Nginx server's native modules and third-party plug-ins. By properly configuring these modules and plug-ins, the performance and functional advantages of the Nginx server can be fully utilized. I hope this article will be helpful to readers when using Nginx server.
