彈性搜索群集

Question

我正在嘗試彈性搜索，並且很難在一台具有3個彈性搜索實例的計算機上創建集群。 我對實例進行了以下更改：

1. 在所有實例上更改了群集名稱{cluster.name：es-stack}
2. 在所有實例上更改了節點名稱{node.name：node-1，node.name：node-2，node.name：node-3}
3. 更改了http端口{http.port：9203，http.port：9202，http.port：9201}
4. 更改了ping單播{discovery.zen.ping.unicast.hosts：[“127.0.0.1:9201”，“127.0.0.1：9202”]}

實例上的elasticsearch.yml看起來像：

# 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"]

在我嘗試啟動實例時進行這些配置后，我無法獲得群集環境。 啟動彈性搜索實例時，日志文件中的錯誤跟蹤說：

我無法確定我錯過了哪一部分？ 如何將所有實例都添加到單個集群？

Answer 1

discovery.zen.ping.unicast.hosts采用host:port數組，這里的端口代表transport.tcp.port而不是http.port 。 所以你的設置應如下所示：

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

您可以在此處閱讀有關此設置的更多信息

希望這可以幫助！
