安装rancher agent时出现以下报错
[root@localhost ~]# sudo docker run --rm --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/ent:v1.2.5 http://192.168.160.130:8080/v1/scripts/6A02DFC097998B0A7659:1483142400000:Eja7GMfVIFpz6o3n017UuZoNNUs

......
原因可能是防火墙引起
[root@localhost ~]# firewall-cmd --state
running
[root@localhost ~]# systemctl stop firewalld
再次执行agent安装
[root@localhost ~]# sudo docker run --rm --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.2.5 http://192.168.160.130:8080/v1/scripts/6A02DFC097998B0A7659:1483142400000:Eja7GMfVIFpz6o3n017UuZoNNUs
