Ansible을 이용한 Zabbix-Agent 배포

원격 시스템에 Zabbix-Agent의 설치 및 설정을 자동화 한다.

활용 용도

• YUM, APT와 같은 Package Manager를 이용하지않고, Package 파일로 직접 설치한다.
• Zabbix-Agent의 사전 검토된 설정을 배포할 때 유용하다. 사전 검토된 설정은 Jinja2 템플릿을 사용한다.

Inventory 설정

# cat hosts
[ALL_HOSTS]
172.16.0.100 managed_ip=172.16.0.100 des="2020-12-03"

[ALL_HOSTS_OK]

대상 호스트는 172.16.0.100이며, 추가는 2020-12-03에 수행한다. 참고적으로 ALL_HOSTS_OK 호스트 그룹은 작업이 완료된 호스트의 history를 위한 그룹이다.

Host Variables 설정

# cat host_vars/172.16.0.100
ansible_ssh_host: 172.16.0.100
ansible_ssh_port: SSH_포트번호
ansible_ssh_user: 사용자 아이디
ansible_ssh_pass: "사용자 패스워드"
ansible_become: yes
ansible_become_method: su
ansible_become_user: root
ansible_become_pass: "!root_패스워드"
