集群安装
安装准备
rke部署不允许使用root 用户，需要新建一个集群部署账户或者将现有账户添加docker 用户组.
本次采取将现有k8suser账户添加到 docker
#单机
usermod k8suser -G docker
#批量
ansible kub-all -m shell -a "usermod k8suser -G docker"
#验证
[root@cnvs-kubm-101-103 kub-deploy]# ansible kub-all -m shell -a "id k8suser"
10.20.10.107 | CHANGED | rc=0 >>
uid=1000(k8suser) gid=1000(k8suser) groups=1000(k8suser),992(docker)
#kub-all 包含集群所有主机创建集群用户方法
groupadd docker && useradd rancher -G docker
echo "123456" | passwd --stdin rancherssh免密登录
在安装主机上与安装集群所有节点（安装集群用户）打通ssh无密码验证。
ansible kub-all -m shell -a "echo 'ssh-rsa AAAAB3NzaC1yaLuTb ' >>/home/k8suser/.ssh/authorized_keys"

安装完成查看 Kubernetes集群状态文件
Kubernetes集群状态由Kubernetes集群中的集群配置文件cluster.yml和组件证书组成，由RKE生成，但根据您的RKE版本，集群状态的保存方式不同。
从v0.2.0开始，RKE在集群配置文件cluster.yml的同一目录中创建一个.rkestate文件。该.rkestate文件包含集群的当前状态，包括RKE配置和证书。需要保留此文件以更新集群或通过RKE对集群执行任何操作。
[root@cndh2321-6-13 rke]# ll
-rw-r----- 1 root root 121198 Aug 30 18:04 cluster.rkestate
-rw-r--r-- 1 root root 1334 Aug 30 16:31 cluster.yml

集群管理节点环境初始化
集群管理节点：10.20.10.103
1:安装完成首先修改:kube_config_cluster.yml
apiVersion: v1
kind: Config
clusters:
- cluster:
.......
FLS0tLS0K
server: "https://10.20.10.253:16443" <=== 修改地址为集群master节点vip 地址和端口：
.....
user: "kube-admin-cn-kube-prod"2：如果安装节点部署集群节点，需要将部署节点 copy （kube_config_cluster.yml） 配置文件至集群管理节点
scp kube_config_cluster.yml 10.20.10.103:/etc/kubernetes/3：配置环境变量：
rm -rf $HOME/.kube
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/kube_config_cluster.yml $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
安装kubectl 集群管理工具
yum -y install kubectl#验证集群
查看集群版本：
kubectl --kubeconfig /etc/kubernetes/kube_config_cluster.yml version or kubectl version

以外部HTTP L7负载均衡器作为访问入口，使用公司购买企业ssl证书，使用外部七层负载均衡器作为访问入口，那么将需要把ssl证书配置在L7负载均衡器上面，如果是权威认证证书，rancher侧则无需配置证书。pt业务环境使用nginx作为代理工具，将ssl 放在nginx端。
