红帽全球峰会第 9 章 执行基本 overcloud 管理任务
本章介绍在 overcloud 生命周期过程中可能需要执行的基本任务。
9.1. 通过 SSH 访问 overcloud 节点
复制链接链接已复制到粘贴板!
您可以通过 SSH 协议访问每个 overcloud 节点。
-
每个 overcloud 节点都包含一个
tripleo-admin用户，以前称为heat-admin用户。 -
undercloud 上的
stack用户具有对各个 overcloud 节点上的tripleo-admin用户进行基于密钥的 SSH 访问权限。 -
所有 overcloud 节点都有一个短主机名，undercloud 将其解析为 control plane 网络上的 IP 地址。每个短主机名都使用
.ctlplane后缀。例如，overcloud-controller-0的短名称为overcloud-controller-0.ctlplane
先决条件
- 具有可正常工作的 control plane 网络的已部署 overcloud。
步骤
-
以
stack用户身份登录 undercloud。 查找要访问的节点的名称：
metalsmith list
(undercloud)$ metalsmith listCopy to Clipboard Copied! Toggle word wrap Toggle overflow 以
tripleo-admin用户身份连接到节点：ssh tripleo-admin@overcloud-controller-0.ctlplane
(undercloud)$ ssh tripleo-admin@overcloud-controller-0.ctlplaneCopy to Clipboard Copied! Toggle word wrap Toggle overflow
