Elasticsearch集群安装

Elasticsearch集群安装,第1张

Elasticsearch集群安装 1 环境说明 linux版本(uname --a 查看)

Linux ubuntu 5.11.0-38-generic #42~20.04.1-Ubuntu SMP Tue Sep 28 20:41:07 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux()

JDK版本(java -v)

Java version "1.8.0_311"

docker版本(docker -v)

Docker version 20.10.10, build b485636

Elasticsearch版本

elasticsearch:7.1.1

注:可通过​​​​​​Docker Hub查看elasticsearch相关的docker镜像

2 Elasticsearch安装步骤 2.1 拉取镜像
sudo docker pull elasticsearch:7.6.2

2.2 查看镜像
sudo docker images

2.3 创建挂载目录
  • data:存放索引数据
  • plugins:存放es插件
## -创建挂载目录[data:存放索引数据,plugins:存放es插件]
mkdir -p /home/zhongqiu/elasticsearch

mkdir -p  /home/zhongqiu/elasticsearch/config/data1
mkdir -p  /home/zhongqiu/elasticsearch/config/data2
mkdir -p  /home/zhongqiu/elasticsearch/config/data3
mkdir -p  /home/zhongqiu/elasticsearch/config/plugins1
mkdir -p  /home/zhongqiu/elasticsearch/config/plugins2
mkdir -p  /home/zhongqiu/elasticsearch/config/plugins3
 2.4 为挂载目录设置执行权限
## 设置执行权限
chmod 777 /home/zhongqiu/elasticsearch/config/data1 
chmod 777 /home/zhongqiu/elasticsearch/config/data2 
chmod 777 /home/zhongqiu/elasticsearch/config/data3 
2.5 分别创建es的配置文件

--data1/data2/data3 分别创建es.yml [network.publish_host:填写服务器ip]

本文档中集群是在一台虚拟机上的伪集群,但是有三个节点es-node1、es-node2、es-node3。

es-node1配置文件
vim /home/zhongqiu/elasticsearch/config/es1.yml


## 文件内容
 cluster.name: elasticsearch-clusters
 cluster.initial_master_nodes : es-node1

vim /home/zhongqiu/elasticsearch/config/es3.yml

## 文件内容
cluster.name: elasticsearch-clusters 
node.name: es-node3

2.6 调高JVM线程数限制数量

不调整的话,启动可能报错。

sudo vim /etc/sysctl.conf


## 更新或者插入文件内容(有就更新,无则新增)

vm.max_map_count = 262144


## 刷新生效
sudo sysctl -p

 2.7 集群部署

上述的配置文件、文件挂载等步骤做完了开始启动节点、部署集群。

节点1启动
 docker run -e ES_JAVA_OPTS="-Xms2048m -Xmx2048m" 
        -d -p 9201:9201 -p 9301:9301 
        -e ES_MIN_MEM=128m 
        -e ES_MAX_MEM=2048m 
        -v /home/zhongqiu/elasticsearch/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml 
        -v /home/zhongqiu/elasticsearch/config/data1/:/usr/share/elasticsearch/data/ 
        -v /home/zhongqiu/elasticsearch/config/plugins1/:/usr/share/elasticsearch/plugins  
        --restart=always

    elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.6.2/elasticsearch-analysis-ik-7.6.2.zip
重启生效
    docker restart es01 
    docker restart es02 es03 
4 elastic-head安装

部署elasticsearch-head 便于管理es数据

4.1 安装
## 获取镜像
docker pull mobz/elasticsearch-head:5


## 运行镜像
docker run -d 
    --name=es-head 
    -p 9100:9100 
    -m 512m 
    --memory-swap=1024m 
    mobz/elasticsearch-head:5

4.2 校验
