Question

我正在遵循Coreos指南，在现有的etcd群集中启用HTTPS。 Link to Documentation

我有两个问题：

1）使用文档中所述的以下命令将对等URL重新配置为HTTPS：

etcdctl member list | awk -F'[: =]' '{print "etcdctl member update "$1" https:"$7":"$8}'

输出与文档相同，但运行后我想要的输出是什么：

etcdctl member list

我想看到peerUrls更新为HTTPs？

2）我继续配置文档并更改了etcd客户端URL。完成后，群集完全停止通信：

etcd2[5063]: 5ebdc721c084a4b1 is starting a new election at term 20548
etcd2[5063]: 5ebdc721c084a4b1 became candidate at term 20549
etcd2[5063]: 5ebdc721c084a4b1 received vote from 5ebdc721c084a4b1 at term 20549
etcd2[5063]: 5ebdc721c084a4b1 [logterm: 20478, index: 6405417] sent vote request to d5df37b45e3cb90f at term 20549
etcd2[5063]: 5ebdc721c084a4b1 [logterm: 20478, index: 6405417] sent vote request to f3aee5692d89a2a3 at term 20549
etcd2[5063]: 5ebdc721c084a4b1 [logterm: 20478, index: 6405417] sent vote request to fb362473ced21e89 at term 20549
etcd2[5063]: the connection to peer d5df37b45e3cb90f is unhealthy
etcd2[5063]: the connection to peer f3aee5692d89a2a3 is unhealthy
etcd2[5063]: the connection to peer fb362473ced21e89 is unhealthy

当我运行以下命令进行调试时：

sudo etcdctl --ca-file /etc/ssl/etcd/ca.pem --cert-file /etc/ssl/etcd/server.pem --key-file /etc/ssl/etcd/server-key.pem member list

我得到以下输出

Failed to get leader:  client: etcd cluster is unavailable or misconfigured

当我在文档中运行curl时，它会给我正确的输入

curl --cacert /etc/ssl/etcd/ca.pem --cert /etc/ssl/etcd/server.pem --key /etc/ssl/etcd/server-key.pem https://172.16.0.2:2379/v2/stats/self

提前谢谢

cfssl中存在一个错误，导致生成对等证书错误。在使用echo创建再生之后，问题就会重新出现。

HTTPS迁移后，etcd2集群无法通信
