弹性搜索集群

Question

我正在尝试使用弹性搜索，但很难在具有 3 个弹性搜索实例的单台机器上创建集群。我对实例进行了以下更改：

1. 更改了所有实例上的集群名称 {cluster.name: es-stack}
2. 更改了所有实例上的节点名称 {node.name: node-1 , node.name: node-2, node.name: node-3}
3. 更改http端口{http.port: 9203, http.port: 9202, http.port: 9201}
4. 更改了 ping 单播 {discovery.zen.ping.unicast.hosts: ["127.0.0.1:9201", "127.0.0.1:9202"]}

实例上的 elasticsearch.yml 如下所示：

# 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，我无法获得集群环境。启动弹性搜索实例时日志文件中的错误跟踪显示：

我无法确定我错过了什么部分？ 如何将所有实例都放到一个集群中？

Answer 1

discovery.zen.ping.unicast.hosts 接受 host:port 数组，这里的端口代表 transport.tcp.port 而不是 http.port 。所以你的设置应该是这样的：

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

您可以阅读有关此设置的更多信息here。

希望这会有所帮助！
