我已配置3个节点的弹性搜索我的群集无法找到主节点

弹性搜索日志

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
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.2.xxx", "192.168.2.xxx", 
                                    "192.168.2.xxx"]
discovery.zen.minimum_master_nodes: 2 
gateway.recover_after_nodes: 2 
gateway.expected_nodes: 3

我无法找到问题所在

Answer 1

要将节点变为主节点，您需要添加

node.master: true

进入elasticsearch.yml。

从您的配置

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 *主人和6 *奴隶）：

MASTER：

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

从属：

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是打开的吗？

Answer 2

我遇到了类似的错误，但情况有所不同。

我试图在同一台计算机上启动2个ES节点。我已经复制了我的ES目录以启动一个新节点，并且得到RemoteTransportException这个异常。

稍作搜索后，我发现必须删除复制目录中的nodes目录才能启动该节点。此目录通常位于{ES_HOME}/data/nodes或/var/lib/elasticsearch/nodes中。
