CentOS 7.2 1151 install AllInOne problem

[xzzh999]

Hi~ Nice work!

When i follow the quick start step, and execute the kubectl version command, there were errors here:

[root@localhost ansible]# kubectl version
Client Version: version.Info{Major:"1", Minor:"12", GitVersion:"v1.12.1",
GitCommit:"4ed3216f3ec431b140b1d899130a69fc671678f4", 
GitTreeState:"clean", BuildDate:"2018-10-05T16:46:06Z",
 GoVersion:"go1.10.4", Compiler:"gc", Platform:"linux/amd64"}
The connection to the server localhost:8080 was refused - did you specify the right host or port?

and i just have modified the hosts file as follow:

# 'deploy' node, which the ansible-playbooks usually run on
# variable 'NTP_ENABLED(=yes/no)' enables/disables the NTP server 'chrony'
[deploy]
0.0.0.0 NTP_ENABLED=no

# 'etcd' cluster must have odd member(s) (1,3,5,...)
# variable 'NODE_NAME' is the distinct name of a member in 'etcd' cluster
[etcd]
0.0.0.0 NODE_NAME=etcd1

[kube-master]
0.0.0.0

[kube-node]

change 0.0.0.0 to a specific addr of the OS，and run ansible-playbook 90.setup.yml again

Not working, reference to this, i also tried the command:
export KUBERNETES_MASTER=http://80.0.0.245:8080,
just the same errors:

[root@localhost ansible]# kubectl version
Client Version: version.Info{Major:"1",
 Minor:"12", GitVersion:"v1.12.1", GitCommit:"4ed3216f3ec431b140b1d899130a69fc671678f4", 
GitTreeState:"clean", BuildDate:"2018-10-05T16:46:06Z", 
GoVersion:"go1.10.4", Compiler:"gc", Platform:"linux/amd64"}
The connection to the server 80.0.0.245:8080 was
 refused - did you specify the right host or port?

and when i execute ansible-playbook 90.setup.yml, there're not any info print, like ok or failed message, just silent end, i use the k8s.1-12-1.tar.gz and basic_images_kubeasz_0.3.tar.gz offline files.

[gjmzj]

run ansible-playbook 99.clean.yml, or just use a new VM and start from the beginning.

@gjmzj
