Nginx 基本配置

Nginx 是一个高性能的 HTTP 和反向代理 web 服务器，同时也提供了 IMAP/POP3/SMTP 服务，其因丰富的功能集、稳定性、示例配置文件和低系统资源的消耗受到了开发者的欢迎。本文，我们总结了一些常用的 Nginx 配置代码，希望对大家有所帮助。

侦听端口

server {
    # Standard HTTP Protocol
    listen 80;
    # Standard HTTPS Protocol
    listen 443 ssl;
    # For http2
    listen 443 ssl http2;
    # Listen on 80 using IPv6
    listen [::]:80;
    # Listen only on using IPv6
    listen [::]:80 ipv6only=on;
}

访问日志

server {
    # Relative or full path to log file
    access_log /path/to/file.log;
    # Turn 'on' or 'off'
    access_log on;
}

域名

server {
    # Listen to yourdomain.com
    server_name yourdomain.com;
    # Listen to multiple domains  server_name yourdomain.com www.yourdomain.com;
    # Listen to all domains
    server_name *.yourdomain.com;
    # Listen to all top-level domains
    server_name yourdomain.*;
    # Listen to unspecified Hostnames (Listens to IP address itself)
    server_name "";
}

静态资源

server {
    listen 80;
    server_name yourdomain.com;
    location / {
        root /path/to/website;
    }
}

重定向

server {
    listen 80;
    server_name www.yourdomain.com;
    return 301 http://yourdomain.com$request_uri;
}

server {
    listen 80;
    server_name www.yourdomain.com;
    location /redirect-url {
        return 301 http://otherdomain.com;
    }
}

反向代理

server {
    listen 80;
    server_name yourdomain.com;
    location / {
        proxy_pass http://0.0.0.0:3000;
        # where 0.0.0.0:3000 is your application server (Ex: node.js) bound on 0.0.0.0 listening on port 3000
    }
}

负载均衡

upstream node_js {
    server 0.0.0.0:3000;
    server 0.0.0.0:4000;
    server 123.131.121.122;
}

server {
    listen 80;
    server_name yourdomain.com;
    location / {
        proxy_pass http://node_js;
    }
}

SSL 协议

server {
    listen 443 ssl;
    server_name yourdomain.com;
    ssl on;
    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/privatekey.pem;
    ssl_stapling on;
    ssl_stapling_verify on;
    ssl_trusted_certificate /path/to/fullchain.pem;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_session_timeout 1h;
    ssl_session_cache shared:SSL:50m;
    add_header Strict-Transport-Security max-age=15768000;
}

# Permanent Redirect for HTTP to HTTPS
server {
    listen 80;
    server_name yourdomain.com;
    return 301 https://$host$request_uri;
}
