负载均衡

http {
    # upstream 模块来配置后端服务器群组
    # 使用 server 指令指定对应的地址和参数
    # 在 server 配置 proxy_pass 指令将请求转发到定义好的服务器群组
    # weight 参数，用于指定更高的权重，意味着在负载均衡中将更倾向于分配更多的请求给它
    upstream backend {
        server backend1.example.com;
        server backend2.example.com;
        server backend3.example.com;
        # 可以设置权重
        server backend4.example.com weight=2;
    }

    server {
        listen 80;

        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;
        }
    }
