Nginx根据域名转发请求

server {
    listen       80;
    server_name *.youdomain.com;
    if ($http_host ~* "^(.*?).youdomain.com$") {
           set $domain $1;
    }
     location / {
        if ($domain ~* "jenkins") {  #域名中有jenkins，转发到8080端口
            proxy_pass http://0.0.0.0:8080;      
        }
        # 默认情况
        root   /var/www/html;
        index  index.html index.htm;
     }
}
