VM

  1. CensOS clone 3개 생성

    → ans1, ans2, ans3

  2. IP 주소 변경

    vi /etc/sysconfig/network-scripts/ifcfg-ens32
    1. ans1: 211.183.3.10
    2. ans2: 211.183.3.20
    3. ans3: 211.183.3.30

  3. hostname 변경

    hostnamectl set-hostname ans1

  4. ans1 NetworkManager 끄기

    [root@ans1 ~]# systemctl stop NetworkManager
[root@ans1 ~]# systemctl disable NetworkManager

Ansible 설치

  1. [root@ans1 ~]# yum -y update

  2. [root@ans1 ~]# yum install -y epel-release [root@ans1 ~]# yum install -y ansible

  3. [root@ans1 ~]# vi /etc/ansible/hosts

    **211.183.3.20 #ans2
211.183.3.30 #ans3**

# This is the default ansible 'hosts' file.
#
# It should live in /etc/ansible/hosts
#
#   - Comments begin with the '#' character
#   - Blank lines are ignored
#   - Groups of hosts are delimited by [header] elements
#   - You can enter hostnames or ip addresses
#   - A hostname/ip can be a member of multiple groups

연결 확인(inven 설정 없이)

  1. [root@ans1 ~]# ansible all -m ping

    서버 개수만큼 무지성 yes

    네트워크 연결을 위한 fingerprint를 만드는 작업이다.

    근데 현재는 인증 정보가 없어서 연결이 불가능하다.

  2. [root@ans1 ~]# ansible all -m ping -k

연결 확인(inven 설정)

  1. [root@ans1 ~]# cd /etc/ansible [root@ans1 ansible]# vi my_inven.txt

    211.183.3.20
211.183.3.30

  2. [root@ans1 ansible]# ansible all -i my_inven.txt -m ping -k
