【ElasticSearch】03 部署

Windows集群部署：

把包解压成三个节点【kibana-7.16.3-windows-x86_64.zip】

- Node-1001
- Node-1002
- Node-1003

修改集群的配置信息

- Node-1001\config\elasticsearch.yml
- Node-1002\config\elasticsearch.yml
- Node-1003\config\elasticsearch.yml

配置信息：

============================== Node-1001 ==========================
# 集群名称一致
cluster.name: Cloud9-WIN-ES-CAT

#节点名称，集群内要唯一
node.name: node-1001
node.master: true
node.data: true

# ip 地址
network.host: localhost
# http 端口
http.port: 1001
# tcp 监听端口
transport.tcp.port: 9301

# 跨域配置
http.cors.enabled: true
http.cors.allow-origin: "*"
============================== Node-1002 ==========================
# 集群名称一致
cluster.name: Cloud9-WIN-ES-CAT

#节点名称，集群内要唯一
node.name: node-1002
node.master: true
node.data: true

# 候选主节点
discovery.seed_hosts: ["localhost:9301"]
discovery.zen.fd.ping_timeout: 1m
discovery.zen.fd.ping_retries: 5

# ip 地址
network.host: localhost
# http 端口
http.port: 1002
# tcp 监听端口
transport.tcp.port: 9302

# 跨域配置
http.cors.enabled: true
http.cors.allow-origin: "*"
============================== Node-1003 ==========================
# 集群名称一致
cluster.name: Cloud9-WIN-ES-CAT

#节点名称，集群内要唯一
node.name: node-1003
node.master: true
node.data: true

#候选主节点的地址，在开启服务后可以被选为主节点
discovery.seed_hosts: ["localhost:9301", "localhost:9302"]
discovery.zen.fd.ping_timeout: 1m
discovery.zen.fd.ping_retries: 5

# ip 地址
network.host: localhost
# http 端口
http.port: 1003
# tcp 监听端口
transport.tcp.port: 9303

# 跨域配置
http.cors.enabled: true
http.cors.allow-origin: "*"

(可选)编写辅助启动脚本【start-cluster.cmd】：

@echo off
start %CD%\Node-1001\bin\elasticsearch.bat
start %CD%\Node-1002\bin\elasticsearch.bat
start %CD%\Node-1003\bin\elasticsearch.bat

(可选)编写辅助清除脚本【clear-nodes.cmd】：

@ECHO OFF
RD /S /Q %CD%\Node-1001\data\nodes
RD /S /Q %CD%\Node-1002\data\nodes
RD /S /Q %CD%\Node-1003\data\nodes

启动之前，删除data目录下的nodes目录

然后依次启动

bin\elasticsearch.bat

请求节点地址，查看节点运行状态【GET请求】

http://localhost:1001/_cluster/health
http://localhost:1002/_cluster/health
http://localhost:1003/_cluster/health

响应这些信息表示正常

{
    "cluster_name": "Cloud9-WIN-ES-CAT",
    "status": "green",
    "timed_out": false,
    "number_of_nodes": 1,
    "number_of_data_nodes": 1,
    "active_primary_shards": 3,
    "active_shards": 3,
    "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
}

或者是查看cat/nodes?v查看集群状态

http://localhost:1001/_cat/nodes?v
http://localhost:1002/_cat/nodes?v
http://localhost:1003/_cat/nodes?v

响应的信息：

ip        heap.percent ram.percent cpu load_1m load_5m load_15m node.role   master name
127.0.0.1           20          97  19                          cdfhilmrstw -      node-1003
127.0.0.1           21          97  19                          cdfhilmrstw -      node-1002
127.0.0.1           16          97  19                          cdfhilmrstw *      node-1001

# 测试集群是否是相互通信的？

# 在1001节点创建一个sample索引

PUT http://localhost:1001/sample

# 然后去1002节点和1003节点上面查看sample索引信息
# 如果其他节点能够找到1001节点的索引，说明集群是相互通信的

GET http://localhost:1003/sample
GET http://localhost:1002/sample

Linux集群部署：

首先提供集群服务环境（每台虚拟机最少提供2G内存，内存过低将导致服务无法集群通信）

192.168.177.128
192.168.177.129
192.168.177.130

每台机器都需要有ES的包

elasticsearch-7.16.0-linux-x86_64.tar.gz

解压包到/opt/module目录下面

mkdir -p /opt/module/
tar -zxvf elasticsearch-7.16.0-linux-x86_64.tar.gz -C /opt/module/

# （可选）变更目录名称

mv /opt/module/elasticsearch-7.16.0 /opt/module/es

# 创建elasticsearch用户, 设置密码123456

useradd user-es
passwd user-es

# 权限赋予

chown -R user-es:user-es /opt/module/elasticsearch-7.16.0/

# 编辑集群参数

mv /opt/module/elasticsearch-7.16.0/config/elasticsearch.yml /opt/module/elasticsearch-7.16.0/config/elasticsearch.yml.bak
vim /opt/module/elasticsearch-7.16.0/config/elasticsearch.yml
