HTTPS 迁移后 etcd2 集群无法通信

Question

我正在按照 Coreos 指南在现有 etcd 集群中启用 HTTPS。 Link to Documentation

我有两个问题：

1) 使用文档中所述的以下命令将 Peer URL 重新配置为 HTTPS 后：

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 etcd 客户端 URL。之后集群完全停止通信：

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

当我按照文档中的方式运行 curl 时，它会为我提供正确的输入

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

cfssl 中存在导致对等证书生成错误的错误。使用 echo 创建重新生成后，问题自行解决。
