Workstation에서 ssh 할 수 없음

[workstation]$ knife ssh 'name:node01' hostname -x root
could not access

해결 방법

1. knife ssh에서 attribute 지정

Default의 ipaddress가 아니라,

[node]# ohai | grep ipaddress
  "ipaddress": "192.168.0.10",

다른 ip address를 지정하고 싶습니다.

[workstation]$ knife ssh 'name:node01' hostname -x root -a <ATTRIBUTE>

예를 들어,이 attribute를 지정하고 싶습니다.

[node]# chef-apply -e 'puts node[:network][:interfaces][:eth1][:routes][0][:src]'
10.10.0.10

[node]# chef-shell -z
chef (12.5.1)> attributes_mode
chef:attributes (12.5.1)>
chef:attributes > node[:network][:interfaces][:eth1][:routes][0][:src]
 => "10.10.0.10"

그러나 knife ssh의 attribute에는 지정할 수 없습니다. 어쩌면 지정 방법이 잘못되었을 것입니다.

[workstation]$ knife ssh 'name:node01' hostname -x root -a network.interfaces.eth1.routes.[0].src
ERROR: TypeError: no implicit conversion of String into Integer

[workstation]$ knife ssh 'name:node01' hostname -x root -a network.interfaces.eth1.routes.0.src
ERROR: TypeError: no implicit conversion of String into Integer

2. node의 ip address 변경

Download node json file

[workstation]$ knife download nodes/node01.json
Created nodes/node01.json

json 수정

[workstation]$ vi nodes/node01.json

[workstation]$ knife diff nodes/node01.json
diff --knife nodes/node01.json nodes/node01.json

3. custom ohai plugin 사용

환경

[chef server]# rpm -q chef-server-core
