Answer 2

自己弄清楚。您可以使用选项--formatter json 在rabbitmq documentation中找不到它！

sudo rabbitmqctl cluster_status --formatter json

sudo rabbitmqctl cluster_status --formatter json | jq .running_nodes

要对此进行解析并在bash脚本中使用：

running_nodes=($(egrep -o '[a-z0-9@-]+' <<< $(sudo rabbitmqctl cluster_status --formatter json | jq .running_nodes)))
