我是靠谱客的博主专一灯泡，最近开发中收集的这篇文章主要介绍ElasticSearch window 服务器扩容，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1.创建elasticsearch-cluster文件夹,在内部复制三个elasticsearch服务

2.修改集群文件目录中第一个节点的config/elasticsearch.yml配置文件

	参数	值	说明
1	cluster.name	my-application	集群名称,节点之间保持一致
2	node.name	node-1001	节点名称,集群内要唯一
3	discovery.seed_hosts	["192.168.2.3:9301","192.168.2.3:9302","192.168.2.3:9303"]
4	cluster.initial_master_nodes	["192.168.2.3:9301"]	maste节点必须有
5	network.host	0.0.0.0	IP
6	http:port	9201	http:端口
7	transport.tcp.port	9301	Tcp监听端口
8	bootstrap.memory_lock	true
9	bootstrap.system_call_filter	false
10	http.cors.enabled	true	跨域配置
11	http.cors.allow-origin	“*”

3.执行 bin/elasticsearch.bat, 启动节点服务器，启动后，会自动加入指定名称的集群

4.启动node-1001后，查看集群状态

在Postman中向ES服务器发,GET: http://localhost:9201/_cluster/health

{
    "cluster_name": "my-application",
    "status": "green",
    "timed_out": false,
    "number_of_nodes": 1,
    "number_of_data_nodes": 1,
    "active_primary_shards": 0,
    "active_shards": 0,
    "relocating_shards": 0,
    "initializing_shards": 0,
    "unassigned_shards": 0,
    "delayed_unassigned_shards": 0,
    "number_of_pending_tasks": 0,
    "number_of_in_flight_fetch": 0,
    "task_max_waiting_in_queue_millis": 0,
    "active_shards_percent_as_number": 100.0
}

5.修改集群文件目录中第二个节点的config/elasticsearch.yml配置文件

	参数	值	说明
1	cluster.name	my-application	集群名称,节点之间保持一致
2	node.name	node-1002	节点名称,集群内要唯一
3	discovery.seed_hosts	["192.168.2.3:9301","192.168.2.3:9302","192.168.2.3:9303"]
4	cluster.initial_master_nodes	["192.168.2.3:9301"]	maste节点必须有
5	network.host	0.0.0.0	IP
6	http:port	9202	http:端口
7	transport.tcp.port	9302	Tcp监听端口
8	bootstrap.memory_lock	true
9	bootstrap.system_call_filter	false
10	http.cors.enabled	true	跨域配置
11	http.cors.allow-origin	“*”
12

6.启动node-1002后，查看集群状态

在Postman中向ES服务器发,GET: http://localhost:9201/_cluster/health

{
    "cluster_name": "my-application",
    "status": "green",
    "timed_out": false,
    "number_of_nodes": 2,
    "number_of_data_nodes": 2,
    "active_primary_shards": 0,
    "active_shards": 0,
    "relocating_shards": 0,
    "initializing_shards": 0,
    "unassigned_shards": 0,
    "delayed_unassigned_shards": 0,
    "number_of_pending_tasks": 0,
    "number_of_in_flight_fetch": 0,
    "task_max_waiting_in_queue_millis": 0,
    "active_shards_percent_as_number": 100.0
}

7.修改集群文件目录中第三个节点的config/elasticsearch.yml配置文件

	参数	值	说明
1	cluster.name	my-application	集群名称,节点之间保持一致
2	node.name	node-1003	节点名称,集群内要唯一
3	discovery.seed_hosts	["192.168.2.3:9301","192.168.2.3:9302","192.168.2.3:9303"]
4	cluster.initial_master_nodes	["192.168.2.3:9301"]	maste节点必须有
5	network.host	0.0.0.0	IP
6	http:port	9203	http:端口
7	transport.tcp.port	9303	Tcp监听端口
8	bootstrap.memory_lock	true
9	bootstrap.system_call_filter	false
10	http.cors.enabled	true	跨域配置
11	http.cors.allow-origin	“*”

8.启动node-1003后，查看集群状态

在Postman中向ES服务器发,GET: http://localhost:9201/_cluster/health

{
    "cluster_name": "my-application",
    "status": "green",
    "timed_out": false,
    "number_of_nodes": 3,
    "number_of_data_nodes": 3,
    "active_primary_shards": 0,
    "active_shards": 0,
    "relocating_shards": 0,
    "initializing_shards": 0,
    "unassigned_shards": 0,
    "delayed_unassigned_shards": 0,
    "number_of_pending_tasks": 0,
    "number_of_in_flight_fetch": 0,
    "task_max_waiting_in_queue_millis": 0,
    "active_shards_percent_as_number": 100.0
}

9. discovery.seed_hosts值最少是填写３个，少了运行不起来,如果每个节点都是一台服务器，可以把端口呈去掉按默认9300即可

10.如想添加第４个节点，配置如下:

	参数	值	说明
1	cluster.name	my-application	集群名称,节点之间保持一致
2	node.name	node-1004	节点名称,集群内要唯一
3	discovery.seed_hosts	["192.168.2.3:9301","192.168.2.3:9302" ,"192.168.2.3:9303","192.168.2.3:9304"]
4	cluster.initial_master_nodes	["192.168.2.3:9301"]	maste节点必须有
5	network.host	0.0.0.0	IP
6	http:port	9204	http:端口
7	transport.tcp.port	9304	Tcp监听端口
8	bootstrap.memory_lock	true
9	bootstrap.system_call_filter	false
10	http.cors.enabled	true	跨域配置
11	http.cors.allow-origin	“*”
