　　make && make install

　　mkdir /software/servers/nginx/conf/vhost

4.修改配置

　　vim /software/servers/nginx/conf/nginx.conf

　　

http {
    include       mime.types;
    default_type  application/octet-stream;

    #access_log  "pipe:rollback logs/access_log interval=1d baknum=7 maxsize=2G"  main;

    sendfile        on;

    keepalive_timeout  65;
    vhost_traffic_status_zone;
    include vhost/upstream.conf;加载初始持久配置
    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        #access_log  "pipe:rollback logs/host.access_log interval=1d baknum=7 maxsize=2G"  main;

        location / {
         set $web "t1"; 
         proxy_set_header Host $host;
         proxy_pass http://$web;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }

      server {
        listen 8081;
        location / {
            dyups_interface;
            access_log   logs/dumps.log;
            allow 127.0.0.1;
            deny all;
        }
    }

}

　　vim /software/servers/nginx/conf/vhost/upstream.conf

　　upstream t1{

　　　　server 192.168.159.130:80;

　　}

　　

动态添加

curl -d "server 192.168.159.130:80;server 192.168.159.133:80;" 127.0.0.1:8081/upstream/t1

 

动态删除

curl -i -X DELETE 127.0.0.1:8081/upstream/t1
