         * 1、本地机器启动了主节点hub    （假設本台机器IP：192.32.50.26，http://localhost:4444/grid/console 查看节点连接情况）
         * java -jar selenium-server-standalone-2.41.0.jar -role hub  （默认端口4444）
         * 2、本地也启动了一个该hub  次节点A   
         * java -jar selenium-server-standalone-2.41.0.jar -role node   
         * （默认的注册地址：http://localhost:4444/grid/register，node默认端口：5555）
         * （具体设置：java -jar selenium-server-standalone-2.41.0.jar -role node -port 5556 -hub http://localhost:4441/grid/register）
         * 3、本机器装有firefox, chrome，所以通过该次节点A， 可以用firefox来运行脚本， 也可以用chrome
         * FF驱动默认在webDriver中了，   而chrome驱动需要自己指定， chromeDriver.exe ，运行chromeDriver（默认使用端口9515）
