Create inventory(Ansible hosts) file

mbpr15:Homebrew cychong$ cat /etc/ansible/hosts
mini1 ansible_host=x.y.z.a ansible_ssh_user=cychong ansible_ssh_port=22
mini2 ansible_host=x.y.z.b ansible_ssh_user=cychong ansible_ssh_port=22
localhost     ansible_connection=local

ping

ping 명령도 ansible이 제공하는 ping module을 이용하므로 -m 옵션을 사용한다.

mbpr15:Homebrew cychong$ ansible all -m ping -k
SSH password: 
localhost | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
mini2 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
mini1 | UNREACHABLE! => {
    "changed": false,
    "msg": "timed out",
    "unreachable": true
}

ssh의 로그인 ID는 /etc/ansible/hosts에 기술하거나 명령어 옵션 —user=cychong으로 지정할 수 있다.

shell module

syntax

-m MODULE_NAME
-a MODULE_ARG
[-u/--user] USER_ID
[-sudo] 로그인 후 SUDO 권한으로 명령어 실행
[-sudo-user USER_ID] 로그인 후 특정 USER_ID 권한으로 명령어 실행 
[-b] -sudo 옵션 대체
[--become-user USER_ID] -sudo-user 옵션 대체

example

shell module의 명령어 df -k 실행 (df -h를 인자로 지정하면 -h가 ansible 명령의 —help 옵션으로 간주된다. 그러므로 이 경우에는 ”df -h”와 같이 따옴표로 module argument를 묶어준다)

mbpr15:Homebrew cychong$ ansible all -m shell -a df -k
