nginx 配置技巧

需求一、域名映射

    server{
        listen        80;
        server_name  www.dimonho.com;
        location / {
            proxy_pass http://192.168.1.92:18080;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            client_max_body_size 100m;
        }
    }

需求二、将dimonho.com自动转发到www.dimonho.com

    server{
        listen        80;
        server_name  dimonho.com www.dimonho.com;
        if ($host = 'dimonho.com'){
            rewrite ^/(.*)$ http://www.dimonho.com/$1 permanent;
        }
        location / {
            proxy_pass http://192.168.1.92:18080;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            client_max_body_size 100m;
        }
    }

需求三、www.dimonho.com集群负载均衡

    upstream  dh.com {
        server 192.168.1.92:18080  weight=1;
        server 192.168.1.94:18080  weight=2;
    }
    server{
        listen        80;
        server_name  dimonho.com www.dimonho.com;
        if ($host = 'dimonho.com'){
            rewrite ^/(.*)$ http://www.dimonho.com/$1 permanent;
        }
        location / {
            proxy_pass http://dh.com;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            client_max_body_size 100m;
        }
    }
