故障现象

yeqiang@yeqiang-MS-7B23:/data/VirtualBox VMs$ ansible all -m ping
node-2 | UNREACHABLE! => {
    "changed": false,
    "msg": "Failed to connect to the host via ssh: \nAuthorized users only. All activities may be monitored and reported.\nyeqiang@node-2: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).",
    "unreachable": true

    "changed": false,
    "msg": "Failed to connect to the host via ssh: \nAuthorized users only. All activities may be monitored and reported.\nyeqiang@node-3: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).",

node-1 | UNREACHABLE! => {
    "changed": false,
    "msg": "Failed to connect to the host via ssh: \nAuthorized users only. All activities may be monitored and reported.\nyeqiang@node-1: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).",

故障原因：

当前用户是yeqiang，而配置ssh-copy-id 是root，参考以下指令

ssh root@node-1
ssh root@node-2
ssh root@node-3

解决

ansible指令指定用户root即可

yeqiang@yeqiang-MS-7B23:/data/VirtualBox VMs$ ansible -u root  all -m ping
