我在集群中设置了两个主节点，但它只显示“弹性主节点”而不是“弹性从节点”。（第二个节点没有显示）。我如何解决它？我已经关注了elasticsearch文档，但没有任何更改！
我的主机文件设置：

sudo nano /etc/hosts
192.168.143.30 elastic-master
192.168.143.23 elastic-slave

我的配置文件：

# ---------------------------------- Cluster ------------------------------

cluster.name: elastic-a

# ------------------------------------ Node -------------------------------

node.name: elastic-master
node.master: true
node.data: true

# ---------------------------------- Network ------------------------------

network.host: 192.168.143.30
http.port: 9200

# --------------------------------- Discovery -----------------------------

discovery.seed_hosts: ["192.168.143.30","192.168.143.23"]
cluster.initial_master_nodes: ["elastic-slave", "elastic-master"]

我的第二个配置文件：

# ---------------------------------- Cluster ------------------------------

cluster.name: elastic-a

# ------------------------------------ Node -------------------------------

node.name: elastic-slave
node.master: true
node.data: true

# ---------------------------------- Network ------------------------------

network.host: 192.168.143.23
http.port: 9200

# --------------------------------- Discovery -----------------------------

discovery.seed_hosts: ["192.168.143.30","192.168.143.23"]
cluster.initial_master_nodes: ["elastic-slave", "elastic-master"]
