Nginx常用操作

反向代理：代理客户端请求转发到后端服务器，这样可以实现负载均衡、缓存、SSL 终止等功能

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://backend_server;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

负载均衡：在多个后端服务器之间进行负载均衡

upstream backend {
    server backend1.example.com;
    server backend2.example.com;
}

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://backend;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
    }
}

静态文件服务：图片、CSS、JavaScript 文件等

server {
    listen 80;
    server_name example.com;

    location / {
        root /usr/share/nginx/html;
        index index.html;
    }

    location /images/ {
        root /usr/share/nginx/html;
        expires max;
    }
}

访问控制：限制对特定资源的访问，例如基于 IP 地址的访问控制

server {
    listen 80;
    server_name example.com;

    location /admin {
        allow 192.168.1.0/24;
        deny all;
    }

    location / {
        root /usr/share/nginx/html;
        index index.html;
    }
}
