elasticsearch - Elasticsearch:使用两个节点设置集群

Question

我在集群中设置了两个主节点，但仅显示“elastic-master”而不是“elastic-slave”。(未显示第二个节点)。如何解决？
我已经关注了Elasticsearch文档，但没有任何改变!
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"]

Answer 1

“首先停止服务(sudo服务elasticsearch停止)。删除数据(sudo rm -rf / var / lib / elasticsearch / *)并重新启动服务(sudo服务elasticsearch重新启动)。现在，一切正常!”
