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

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...}
