4.4. 将 Cockpit Ceph Installer SSH 密钥复制到集群中的所有节点

流程

1. 以 Ansible 用户身份登录 Ansible 管理节点。

   ssh ANSIBLE_USER@HOST_NAME

   Copy to Clipboard Toggle word wrap

   例如：

   $ ssh admin@jb-ceph4-admin

   Copy to Clipboard Toggle word wrap

2. 将 SSH 公钥复制到第一个节点：

   sudo ssh-copy-id -f -i /usr/share/ansible-runner-service/env/ssh_key.pub _ANSIBLE_USER_@_HOST_NAME_

   Copy to Clipboard Toggle word wrap

   例如：

   $ sudo ssh-copy-id -f -i /usr/share/ansible-runner-service/env/ssh_key.pub admin@jb-ceph4-mon
   /bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/usr/share/ansible-runner-service/env/ssh_key.pub"
   admin@192.168.122.182's password:
   
   Number of key(s) added: 1
   
   Now try logging into the machine, with:   "ssh 'admin@jb-ceph4-mon'"
   and check to make sure that only the key(s) you wanted were added.

   对集群中的所有节点重复此步骤
