红帽全球峰会1.12. 使用 CLI 从拓扑中删除服务器
您可以使用命令行从拓扑中删除 RHEL 身份管理(IdM)服务器。
先决条件
- 有 IdM 管理员凭证。
- 您希望删除的服务器 并不是 唯一将其他服务器与拓扑中其余部分连接的服务器；这会导致其他服务器变为隔离状态，这是不允许的。
- 要删除的服务器 不是 您的最后一个 CA 或 DNS 服务器。
重要
删除服务器是一项不当操作。如果您删除了服务器，在拓扑中重新引入它的唯一方法是在机器上安装新副本。
流程
删除 server1.example.com ：
在另一台服务器上，运行
ipa server-del命令来删除server1.example.com。该命令删除指向服务器的所有拓扑片段：ipa server-del
[user@server2 ~]$ ipa server-del Server name: server1.example.com Removing server1.example.com from replication topology, please wait... ---------------------------------------------------------- Deleted IPA server "server1.example.com" ----------------------------------------------------------Copy to Clipboard Copied! 可选：在
server1.example.com上，运行ipa server-install --uninstall命令来从机器中卸载服务器组件。ipa server-install --uninstall
[root@server1 ~]# ipa server-install --uninstallCopy to Clipboard Copied!
