检查阶段
运行部署前检查的时候
# ansible-playbook -vv playbooks/prerequisites.yml
需要看看play recap是否全过，如果不过需要定位原因，反复执行
之前在检查阶段，因为node1,node2经常连接不上master(设置为yum源)的repo/base,也就是RHEL7.6的包，暂时解决办法是在repo中分别挂在自己本地的源绕开错误。
部署阶段
# ansible-playbook -vv /usr/share/ansible/openshift-ansible/playbooks/deploy_cluster.yml
安装完成后的提示,如果有不成功，解决问题以后反复执行。

在master节点执行创建admin用户
# htpasswd /etc/origin/master/htpasswd admin
同时赋予admin用户权限
# oc adm policy add-cluster-role-to-user cluster-admin admin
在hosts文件中加入
