etcd集群常见问题

大道之行，天下为公。这篇文章主要讲述etcd集群常见问题相关的知识，希望能为你提供帮助。
1、防火墙问题，systemctl stop firewalld & & systemctl disable firewalld

Aug 16 21:49:11 k01 etcd: health check for peer 1d2b6542084a0b87 could not connect: dial tcp 192.168.1.60:2380: i/o timeout Aug 16 21:49:11 k01 etcd: health check for peer 1d2b6542084a0b87 could not connect: dial tcp 192.168.1.60:2380: i/o

2、集群节点时钟不一至，使用时钟服务器或者ntpdate time.windows.com。

Aug 16 22:13:46 k01 etcd: the clock difference against peer 1d2b6542084a0b87 is too high [2.304656176s > 1s] Aug 16 22:14:16 k01 etcd: the clock difference against peer 1d2b6542084a0b87 is too high [2.29437392s > 1s] Aug 16 22:14:16 k01 etcd: the clock difference against peer 1d2b6542084a0b87 is too high [2.307277917s > 1s]

【etcd集群常见问题】3、etcd集群节点因意外重启后，systemctl start etcd.service无法启动
停掉该etcd
备份此台etcd的数据
把此台etcd数据删除清空
把etcd配置由new改为existing
systemctl start etcd.service ，数据会同步至此台
