我正在尝试在 Ubuntu 18.04 主机上设置集群。使用 DNS 进行服务器发现时出现以下错误。

error setting up initial cluster: cannot find local etcd member "etcd-1" in SRV records

我已经按照文档进行操作，感觉我已经正确完成了所有操作，但是我是设置本地 dns 的新手（使用 bind9），无法判断我在这里做错了什么。我已经尝试改变我的 dns 但无法解决问题。该问题仅在尝试发现本地节点时发生...

这是 _etcd-server 的 SRV 记录

user@etcd-1:~$ dig +noall +answer SRV _etcd-server._tcp.etcd.abc-bird.com
_etcd-server._tcp.etcd.abc-bird.com.    9 IN SRV 0 0 2380 etcd-2.etcd.abc-bird.com.
_etcd-server._tcp.etcd.abc-bird.com.    9 IN SRV 0 0 2380 etcd-3.etcd.abc-bird.com.
_etcd-server._tcp.etcd.abc-bird.com.    9 IN SRV 0 0 2380 etcd-1.etcd.abc-bird.com.

我的 _etcd-client-ssl 的 SRV 记录

user@etcd-1:~$ dig +noall +answer SRV _etcd-client-ssl._tcp.etcd.abc-bird.com
_etcd-client-ssl._tcp.etcd.abc-bird.com. 60 IN SRV 0 0 2379 etcd-2.etcd.abc-bird.com.
_etcd-client-ssl._tcp.etcd.abc-bird.com. 60 IN SRV 0 0 2379 etcd-1.etcd.abc-bird.com.
_etcd-client-ssl._tcp.etcd.abc-bird.com. 60 IN SRV 0 0 2379 etcd-3.etcd.abc-bird.com.

我的 A 记录

user@etcd-1:~$ dig +noall +answer etcd-1.etcd.abc-bird.com. etcd-2.etcd.abc-bird.com. etcd-3.etcd.abc-bird.com.
etcd-1.etcd.abc-bird.com. 35    IN  A   192.168.0.28
etcd-2.etcd.abc-bird.com. 35    IN  A   192.168.0.20
etcd-3.etcd.abc-bird.com. 35    IN  A   192.168.0.29

这是我的 etcd.service 文件内容

对于它的价值，这是我的名称服务器上的 dns 配置。 https://gist.github.com/spstratis/1e89f867d86c6b37dc15387ccd310fcc
