nginx应用场景（附配置）

场景1：web服务器

server {
    listen 80;
    server_name example.com; # 替换为您的域名

    location / {
        root /data/wwwroot;
        index index.html index.htm;
    }
}

server {
    listen 443 ssl;
    server_name example.com; # 替换为您的域名

    ssl_certificate /path/to/certificate.crt;
    ssl_certificate_key /path/to/private-key.key;

    location / {

场景2：反向代理

http {
    server {
        listen 80;
        server_name example.com; # 替换为您的域名

        location / {
            proxy_pass http://127.0.0.1:9000;
            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;

场景3：负载均衡

http {
    upstream backend {
        server backend_server1.example.com; # 替换为您的服务器地址
        server backend_server2.example.com; # 替换为您的服务器地址
        server backend_server3.example.com; # 替换为您的服务器地址
        # 可以添加更多的服务器，或者使用其他负载均衡策略
    }

    server {
        listen 80;
        server_name example.com www.example.com; # 替换为您的域名

        location / {
            proxy_pass http://backend; # 使用定义的 upstream 名称
            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;
        }
    }

场景4： 基于请求路径转发不同的服务器

http {
     server {
        listen 80;
        server_name example.com; # 您的域名

        location /service1/ {
            proxy_pass http://127.0.0.1:1001;
            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;
        }

        location /service2/ {
            proxy_pass http://127.0.0.1:1002;
            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;
        }

        location /service3/ {
            proxy_pass http://127.0.0.1:1003;
            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;
        }

        # 其他 location 配置...
    }
}
