之前已經使用ansible 批量安裝部署啟動過ntp

安裝：ansible -i sms_addtikv.txt all -m shell -a "sudo yum install ntp ntpdate -y" -b

啟動：ansible -i sms_addtikv.txt  all -m shell -a "sudo systemctl start ntpd.service " -b

但是ansible-playbook deploy.yml 安裝tikv時還是報錯：

ERROR MESSAGE SUMMARY ********************************************************************************************************************************************************************************************************************************************************
[172.168.34.89]: Ansible FAILED! => playbook: deploy.yml; TASK: check_system_dynamic : Preflight check - NTP service; message: {"changed": false, "msg": "Make sure NTP service is running and ntpstat is synchronised to NTP server.

先檢視ntp狀態
[[email protected]] ~$ ntpstat
unsynchronised
polling server every 64 s

沒有同步好，接下來手動再操作下
[[email protected]] ~$ ntpstat
unsynchronised
time server re-starting
polling server every 8 s
[[email protected]] ~$ 
[[email protected]] ~$ sudo systemctl stop ntpd.service
[

[[email protected]] ~$ ntpstat
synchronised to NTP server (193.228.143.13) at stratum 3 
time correct to within 170 ms
polling server every 64 s
[[email protected]] ~$

番外：
一般的執行如下命令，基本可以搞定

有時候centos7系統不行，採用下面命令

之後再執行 ansible-playbook deploy.yml命令，就會暢通無阻，順利執行完成。
