使用 RHEL 角色

  1. 參考 timesync 角色文件的範例，撰寫 timesync.yml 腳本，在 dev 受管主機使用 timesync 角色啟用校時服務，時間伺服器 192.168.122.1，啟用 iburst 參數。 
    [deyu1@kvm19 ansible]$ vim timesync.yml
[deyu1@kvm19 ansible]$ cat timesync.yml
---
- hosts: dev
  vars:
    timesync_ntp_servers:
      - hostname: 192.168.122.1
        iburst: yes
  roles:
    - rhel.system_roles.timesync
  2. ansible-playbook 執行 timesync.yml 腳本，輸出 failed=0 表示成功。 
    [deyu1@kvm19 ansible]$ ansible-playbook timesync.yml

  3. 查詢 dev 主機的時間校時服務的設定，是否依 timesync.yml 腳本配置校時伺服器及參數？ 
    [deyu1@kvm19 ansible]$ ansible dev -m shell -a "grep ^server /etc/chrony.conf"
