ansible 설치 및 간단 테스트

centos7 에서 테스트 하였습니다.


ansible 서버에서 ..


[root@template-cent7 /tmp]# yum install ansible
[root@template-cent7 /tmp]# ssh-keygen -t rsa

           그냥 계속 < enter >


ansible 클라이언트에서 ..
[root@template-cent7 /tmp]# useradd ansible
[root@template-cent7 /tmp]# echo "password" | passwd --stdin ansible



다시 ansible 서버에서 ..

[root@template-cent7 /tmp]# cd /root/.ssh
[root@template-cent7 /root/.ssh]# ssh-copy-id -i id_rsa.pub ansible@192.168.231.64
  
[root@template-cent7 /tmp]# vi test.ini
 
test ansible_host=192.168.231.64 ansible_user=ansible



[root@template-cent7 /tmp]# ansible -m ping -i test.ini all
test1 | SUCCESS => {
    "changed": false,
