为提高效率，提问时请提供以下信息，问题描述清晰可优先响应。

  • 【TiDB 版本】：
    3.0.2
  • 【问题描述】：
    1.第一次执行ansible-playbook bootstrap.yml 是通过的，结尾日志如下：

Congrats! All goes well. :slight_smile:

2.部署时却出现ntp不通过的错误：

3.去每台机器上检查了ntp服务 也是正常的

性能优化、故障排查等需要收集“系统/集群信息”的问题，请下载脚本运行。全选终端打印结果，并复制粘贴上传。

2

麻烦在报错节点执行一下 ntpstat | grep -w synchronised | wc -l

3

ntpstat | grep -w synchronised | wc -l
1

4

结果为 1

5

sudo systemctl status ntpd.service 结果也是正常的吗？如果两个结果都是正常的话。重新 deploy 一下，看还有没有报错。

6

您好，问题已解决 公司是用chronyd.service 管理的ntpd与dns，改为直接启动ntpd.service服务就行了
