用途

在第一篇《EFK教程 - 快速入门指南》中，阐述了EFK的安装部署，其中ES的架构为三节点，即master、ingest、data角色同时部署在三台服务器上。

在本文中，将进行角色分离部署，并且每个角色分别部署三节点，在实现性能最大化的同时保障高可用。

▷ elasticsearch的master节点：用于调度，采用普通性能服务器来部署 ▷ elasticsearch的ingest节点：用于数据预处理，采用性能好的服务器来部署 ▷ elasticsearch的data节点：用于数据落地存储，采用存储性能好的服务器来部署

注意：此处的架构是之前的文章《EFK教程 - 快速入门指南》的拓展，因此请先按照《EFK教程 - 快速入门指南》完成部署

步骤说明

1️⃣ 部署3台data节点，加入原集群 2️⃣ 部署3台ingest节点，加入原集群 3️⃣ 将原有的es索引迁移到data节点 4️⃣ 将原有的es节点改造成master节点

elasticsearch-data部署

之前已完成了基础的elasticsearch架构，现需要新增三台存储节点加入集群，同时关闭master和ingest功能

elasticsearch-data安装：3台均执行相同的安装步骤

  1. tar -zxvf elasticsearch-7.3.2-linux-x86_64.tar.gz

  2. mv elasticsearch-7.3.2 /opt/elasticsearch

  3. useradd elasticsearch -d /opt/elasticsearch -s /sbin/nologin

  4. mkdir -p /opt/logs/elasticsearch

  5. chown elasticsearch.elasticsearch /opt/elasticsearch -R

  6. chown elasticsearch.elasticsearch /opt/logs/elasticsearch -R

  7. # 数据盘需要elasticsearch写权限

  8. chown elasticsearch.elasticsearch /data/SAS -R

  9.  

  10. # 限制一个进程可以拥有的VMA(虚拟内存区域)的数量要超过262144，不然elasticsearch会报max virtual memory areas vm.max_map_count [65535] is too low, increase to at least [262144]

  11. echo "vm.max_map_count = 655350" >> /etc/sysctl.conf

  12. sysctl -p

elasticsearch-master部署

首先，将上一篇《EFK教程 - 快速入门指南》中部署的3台es（192.168.1.31、192.168.1.32、192.168.1.33）改成只有master的功能， 因此需要先将这3台上的索引数据迁移到本次所做的data节点中

1️⃣ 索引迁移：一定要做这步，将之前的索引放到data节点上

  1. curl -X PUT "192.168.1.31:9200/*/_settings?pretty" -H 'Content-Type: application/json' -d'

  2. {

  3. "index.routing.allocation.include._ip": "192.168.1.51,192.168.1.52,192.168.1.53"

  4. }'

2️⃣ 确认当前索引存储位置：确认所有索引不在192.168.1.31、192.168.1.32、192.168.1.33节点上

  1. curl "http://192.168.1.31:9200/_cat/shards?h=n"

 

 

elasticsearch-master配置

注意事项：修改配置，重启进程，需要一台一台执行，要确保第一台成功后，再执行下一台。重启进程的方法：由于上一篇文章《EFK教程 - 快速入门指南》里，是执行命令跑在前台，因此直接ctrl - c退出再启动即可，启动命令如下

  1. sudo -u elasticsearch /opt/elasticsearch/bin/elasticsearch

▷ 192.168.1.31 /opt/elasticsearch/config/elasticsearch.yml

  1. cluster.name: my-application

  2. node.name: 192.168.1.31

  10.  

  11. #开启master功能

  12. node.master: true

  13. #关闭ingest功能

  14. node.ingest: false

  15. #关闭data功能

  16. node.data: false

elasticsearch集群状态

  1. curl "http://192.168.1.31:9200/_cat/health?v"

 

 

elasticsearch-master状态

  1. curl "http://192.168.1.31:9200/_cat/nodes?v"

 

 

至此，当node.role里所有服务器都不再出现“mid”，则表示一切顺利完成。
