我正在尝试在三节点集群（主节点、基础架构和计算节点）上安装 openshift origin。 Ansible prereq 失败了，我想了解原因。

我使用的命令：-

ansible-剧本 /usr/share/ansible/openshift-ansible/playbooks/prerequisites.yml --extra-vars "deployment_type=origin ansible_ssh_user=origin ansible_ssh_pass=**********

/etc/ansible/hosts

[OSEv3:children]
masters
infra
compute.openshift.local
[OSEv3:vars]
# admin user created in previous section
ansible_ssh_user=origin
ansible_become=true
openshift_deployment_type=origin

# use HTPasswd for authentication
openshift_master_identity_providers=[{'name': 'htpasswd_auth', 'login': 'true', 'challenge': 'true', 'kind': 'HTPasswdPasswordIdentityProvider'}]
# define default sub-domain for Master node
openshift_master_default_subdomain=master.openshift.local
# allow unencrypted connection within cluster
openshift_docker_insecure_registries=172.30.0.0/16

[masters]
master.openshift.local openshift_schedulable=true containerized=false

[etcd]
master.openshift.local

[nodes]
# defined values for [openshift_node_group_name] in the file below
# [/usr/share/ansible/openshift-ansible/roles/openshift_facts/defaults/main.yml]
# ctrl.srv.world openshift_node_group_name='node-config-master-infra'
# node01.srv.world openshift_node_group_name='node-config-compute'
# node02.srv.world openshift_node_group_name='node-config-compute'

# if you'd like to separate Master node feature and Infra node feature, set like follows
master.openshift.local openshift_node_group_name='node-config-master'
infra.openshift.local openshift_node_group_name='node-config-infra'
compute.openshift.local openshift_node_group_name='node-config-compute'

... [Errno 13] Permission denied: '/etc/ansible/facts.d/openshift.fact'\r\n", "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error", "rc": 1}

以上错误消息的含义是/etc/ansible/facts.d/openshift.fact 无法在使用origin 用户的节点上创建。您能否验证origin 用户是否可以在所有节点上将权限提升为root？

e.g.> 例如，检查是否可以使用sudo 获取root 权限。

origin@hostname ~$ sudo -i
root@hostname ~#
