Question

我已经配置了 3 个节点的弹性搜索我的集群找不到主节点

我的 elasticsearch.yml 文件

cluster.name: cluster-testing 
node.name: node3
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 192.168.2.xxx

discovery.zen.ping.unicast.hosts: ["192.168.2.xxx", "192.168.2.xxx", 
                                    "192.168.2.xxx"]
discovery.zen.minimum_master_nodes: 2

gateway.expected_nodes: 3

我找不到问题出在哪里

Answer 1

我遇到了类似的错误，但我的情况有点不同。

我试图在同一台机器上启动 2 个 ES 节点。我已经复制了我的 ES 目录来启动一个新节点，我得到了 RemoteTransportException 这个异常。

谷歌搜索了一下后，我发现我必须删除复制目录中的nodes 目录才能启动该节点。该目录通常存在于{ES_HOME}/data/nodes 或/var/lib/elasticsearch/nodes。

Answer 2

要将节点变成主节点，您需要添加

node.master: true

进入 elasticsearch.yml。

根据您的配置

discovery.zen.minimum_master_nodes: 2 

至少有两个节点必须将 node.master 设置为 true

编辑：

您可以找到我们项目的以下工作配置（3*masters 和 6*slaves）：

大师：

cluster.name: VAL_elasticsearch
node.name: MASTER-${HOSTNAME}
node.data: false
node.master: true
path.data: /data
path.logs: /local/opt/logs
path.repo: ["/home/data_ElasticSearchBackup"]
bootstrap.memory_lock: true
bootstrap.seccomp: false
network.host: 0.0.0.0
http.port: 9200
transport.tcp.port: 9300
discovery.zen.ping.unicast.hosts: ["ip_master1","ip_master2","ip_masterx"]
discovery.zen.minimum_master_nodes: 2

奴隶：

cluster.name: VAL_elasticsearch
node.name: DATA-${HOSTNAME}
node.data: true
node.master: false
path.data: /data
path.logs: /local/opt/logs
path.repo: ["/home/data_ElasticSearchBackup"]
bootstrap.memory_lock: true
bootstrap.seccomp: false
network.host: 0.0.0.0
http.port: 9200
transport.tcp.port: 9300
discovery.zen.ping.unicast.hosts: ["ip_master1","ip_master2","ip_masterx"]
discovery.zen.minimum_master_nodes: 2

您确定所有弹性实例之间的所有端口都打开了吗？
