我有两个节点 Nomad 集群和一个 Consul 实例，以便作业可以注册要连接的服务。

但是，这些服务会不断同步和取消注册。这是我从领事日志中得到的：

2021-01-26T14:49:59.174Z [INFO]  agent: Synced check: check=_nomad-check-dc23801467b8a65a4fd82311c2606724a180065c

两个节点都以相同的配置启动。但是，当我查看TRACE级别的日志时，我有以下内容：

节点A：

2021-01-28T15:58:55.519+0100 [DEBUG] consul.sync: sync complete: registered_services=3 deregistered_services=1 registered_checks=0 deregistered_checks=0

节点B：

2021-01-28T15:58:59.037+0100 [DEBUG] consul.sync: sync complete: registered_services=1 deregistered_services=3 registered_checks=0 deregistered_checks=0

事实上，NodeA运行了 3 个作业，而NodeB运行了 1 个作业。似乎两个节点都在恢复另一个节点所做的更改。

Name               Address       Port  Status  Leader  Protocol  Build  Datacenter  Region
NodeA              198.51.100.1  4648  alive   false   2         1.0.2  us1         us
NodeB              198.51.100.2  4648  alive   true    2         1.0.2  us1         us

我是否错过了配置中的某些内容？如何防止这种情况？

运行sudo nomad agent -dev结果getsockopt: connection refused：
