tikv节点扩容NTP报错处理记录

之前已经使用ansible 批量安装部署启动过ntp

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

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

但是ansible-playbook deploy.yml 安装tikv时还是报错：

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.

先查看ntp状态
[ansible@st300-hytikv-64] ~$ ntpstat
unsynchronised
polling server every 64 s

没有同步好，接下来手动再操作下
[ansible@st300-hytikv-64] ~$ ntpstat
unsynchronised
time server re-starting
polling server every 8 s
[ansible@st300-hytikv-64] ~$ 
[ansible@st300-hytikv-64] ~$ sudo systemctl stop ntpd.service
[ansible@st300-hytikv-64] ~$ sudo ntpdate pool.ntp.org

[ansible@st300-hytikv-64] ~$ sudo systemctl start ntpd.service
[ansible@st300-hytikv-64] ~$ 
[ansible@st300-hytikv-64] ~$

[ansible@st300-hytikv-64] ~$ ntpstat
synchronised to NTP server (193.228.143.13) at stratum 3

[ansible@st300-hytikv-64] ~$

番外：
一般的执行如下命令，基本可以搞定

有时候centos7系统不行，采用下面命令

之后再执行 ansible-playbook deploy.yml命令，就会畅通无阻，顺利执行完成。
