Question

我正在尝试弹性搜索，并且很难在一台具有3个弹性搜索实例的计算机上创建群集。我对实例进行了以下更改：

在所有实例上更改了群集名称{cluster.name：es-stack}
在所有实例上更改了节点名称{node.name：node-1，node.name：node-2，node.name：node-3}
更改了http端口{http.port：9203，http.port：9202，http.port：9201}
更改了ping单播{discovery.zen.ping.unicast.hosts：[＆＃34; 127.0.0.1：9201＆＃34;，＆＃34; 127.0.0.1：9202＆＃34;]}

实例上的elasticsearch.yml看起来像：

# Instance 1
cluster.name: es-stack
node.name: node-1
http.port: 9201
discovery.zen.ping.unicast.hosts: ["127.0.0.1:9202", "127.0.0.1:9203"]

# Instance 2
cluster.name: es-stack
node.name: node-2
http.port: 9202
discovery.zen.ping.unicast.hosts: ["127.0.0.1:9201", "127.0.0.1:9203"]

# Instance 3
cluster.name: es-stack
node.name: node-3
http.port: 9203
discovery.zen.ping.unicast.hosts: ["127.0.0.1:9201", "127.0.0.1:9202"]

在我尝试启动实例时进行这些配置后，我无法获得群集环境。启动弹性搜索实例时，日志文件中的错误跟踪显示：

我无法确定哪些部分错过了？如何将所有实例都集成到单个集群？

Answer 1

discovery.zen.ping.unicast.hosts包含host:port数组，此处端口代表transport.tcp.port而不是http.port。所以你的设置应如下所示：

discovery.zen.ping.unicast.hosts: ["127.0.0.1:9302", "127.0.0.1:9303"]
//note: 9202 became 9302 and so on

您可以详细了解此设置here。

希望这有帮助！
