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 ********************************************************************************************************************************************************************************************************************************************************

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
26 Oct 16:28:52 ntpdate[31699]: adjust time server 5.103.139.163 offset 0.001772 sec
[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

番外：
一般的执行如下命令，基本可以搞定
| $ sudo systemctl stop ntpd.service $ sudo ntpdate pool.ntp.org $ sudo systemctl start ntpd.service |
|---|
有时候centos7系统不行，采用下面命令
| $ sudo yum install ntp ntpdate $ sudo systemctl start ntpd.service $ sudo systemctl enable ntpd.service |
|---|
之后再执行 ansible-playbook deploy.yml命令，就会畅通无阻，顺利执行完成。
