标签： openstack cloudify

我是openstack / cloudify的新手，尝试在openstack上尝试使用cloudify启动cirros实例。

我使用以下命令启动它

cfy bootstrap --task-retries 1 -p cloudify-manager-blueprints/openstack/openstack.yaml -i cloudify-manager-blueprints/openstack/inputs.json.template

这是input.json 

"keystone_username": "",
"keystone_password": "",
"keystone_tenant_name": "",
"keystone_url": "",
"region": "",
"manager_public_key_name": "",
"agent_public_key_name": "",
"image_id": "19c8a468-93c7-4110-8022-40a4f35deb0c",
"flavor_id": "2",
"external_network_name": "extnet",


"use_existing_manager_keypair": false,
"use_existing_agent_keypair": false,
"manager_server_name": "cloudify-management-server",
"manager_server_user": "ubuntu",
"manager_server_user_home": "/home/ubuntu",
"manager_private_key_path": "~/.ssh/cloudify-manager-kp.pem",
"agent_private_key_path": "~/.ssh/cloudify-agent-kp.pem",
"agents_user": "cirros",
"nova_url": "",
"neutron_url": "",
"resources_prefix": ""

yaml是默认的

主要错误行是 致命错误：需要提示连接或sudo密码（主机：172.16.7.16），但是中止提示设置为True

在json文件中声明以下内容是否正确agent_user =＆gt; cirros cirros image的用户名是cirros

这是完整的错误

Fatal error: Needed to prompt for a connection or sudo password (host: 172.16.7.16), but abort-on-prompts was set to True

Aborting.

如果我将管理用户更改为当前用户（root） 我收到以下错误

所以似乎客户端无法连接到管理机器。

当您尝试与错误的用户建立连接时，这些错误通常会弹出。

确保“manager_server_user”正确无误。

仅在分享我的经验后，遇到同样的错误，请确保您对pem文件拥有正确的所有者cfyuser:cfyuser。 试试手动ssh：

$ sudo -u cfyuser ssh -i <path/to/keypair.pem> ubuntu@<ip>
