ngrinder3.3控制台验证脚本报错
http://ngrinder.642.n7.nabble.com/ngrinder3-3-td1301.html
目前发现3.3版本在控制台校验脚本报错，无法执行，但执行测试分发到压力机上可以正常执行。
已下是错误日志：

控制台的hosts文件如下：
[new@controller-01 logs]$ getent hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
127.0.0.1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.210 controller-01
192.168.1.211 agent-01
192.168.1.212 agent-02
问题分析：
此性能平台环境必须经过DNS解析过一遍，即使解析不到也需要个假DNS Server，它优先走DNS，不本地/etc/hosts解析，这样才能进一步，使用压测平台的脚本验证按钮等。
解决方案：
新增DNS解析： /etc/reslove.conf
nameserver 192.168.131.17
nameserver 192.168.131.18
