2.2. 설치 후 버전 확인
# ansible --version ansible 2.9.23 config file = /etc/ansible/ansible.cfg configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python2.7/site-packages/ansible executable location = /usr/bin/ansible python version = 2.7.18 (default, May 25 2022, 14:30:51) [GCC 7.3.1 20180712 (Red Hat 7.3.1-15)]
3. 컨트롤러 서버와 원격 서버 설정
3.1. 컨트롤러 서버에서 ssh 키 생성
$ ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/ec2-user/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/ec2-user/.ssh/id_rsa. Your public key has been saved in /home/ec2-user/.ssh/id_rsa.pub. The key fingerprint is: ... $ ls -al .ssh/ 합계 20 drwx------ 2 ec2-user ec2-user 80 1월 10 09:55 . drwx------ 14 ec2-user ec2-user 4096 11월 30 07:22 .. -rw------- 1 ec2-user ec2-user 401 10월 18 00:31 authorized_keys -rw------- 1 ec2-user ec2-user 1679 1월 10 09:55 id_rsa -rw-r--r-- 1 ec2-user ec2-user 438 1월 10 09:55 id_rsa.pub
키 내용을 확인한다.
$ cat .ssh/id_rsa.pub
위 내용을 잘 기억한다.
3.2. 원격 서버 작업
위 내용을 아래 파일의 끝에 붙여넣는다.
vi .ssh/authorized_keys
4. 원격 서버 등록
컨트롤러 서버 원격 서버 IP 주소를 등록한다.
sudo vi /etc/ansible/hosts
그리고 ansible 명령어를 이용하여 ping을 날려본다.
ansible all -m ping
