ERROR : Error appeared during Puppet run: 172.16.2.120_keystone.pp Error: /Stage[main]/Keystone::Roles::Admin/Keystone_role[_member_]: Could not evaluate: Execution of '/usr/bin/keystone --os-endpoint http://127.0.0.1:35357/v2.0/ role-list' returned 1: An unexpected error prevented the server from fulfilling your request.

解决：
编辑host文件，添加主机名和对应的ip地址到host文件。
vi /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 127.0.0.1 Node1 -----------------------------------------------------------------------------------------------------------------
这个地方前面的ip地址最好填127.0.0.1，应为RDO安装的Mysql默认只能这个ip地址连接，如果你填写的是本机网卡的ip地址，会报如下错误
