准备

1.服务器创建es用户

useradd es
passwd es

2.elasticsearch部署环境JDK

3.安装包
可以去elastic官网下载相应版本文件。我这里安装版本的是7.12.0。
Linux版本：

//centos下若没有安装curl
yum install curl
//进入es用户目录执行下载
curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.12.0-linux-x86_64.tar.gz

安装

解压下载的压缩文件

tar -xzvf elasticsearch-7.12.0-linux-x86_64.tar.gz

启动elasticsearch

cd elasticsearch-7.12.0/bin/
./elasticsearch &

访问elasticsearch

curl http://127.0.0.1:9200//返回信息
{"name" : "izwz9ja3exxb7by25st5gbz","cluster_name" : "elasticsearch","cluster_uuid" : "hD8cxBoIRvW6tZUEIFMTUQ","version" : {"number" : "7.12.0","build_flavor" : "default","build_type" : "tar","build_hash" : "78722783c38caa25a70982b5b042074cde5d3b3a","build_date" : "2021-03-18T06:17:15.410153305Z","build_snapshot" : false,"lucene_version" : "8.8.0","minimum_wire_compatibility_version" : "6.8.0","minimum_index_compatibility_version" : "6.0.0-beta1"},"tagline" : "You Know, for Search"
}

集群启动：
修改配置文件

vim elasticsearch.yml//配置集群名称
cluster.name: elasticsearch
//配置节点名称
node.name: node-1
//配置数据存放路径
path.data: /path/to/data
//配置日志存放路径
path.logs: /path/to/logs
//配置访问地址 所有机器可访问 则配置为0.0.0.0
network.host: 0.0.0.0
//配置访问端口
http.port: 9200
//配置集群扫描地址
discovery.seed_hosts: ["172.18.88.96", "127.0.0.1"]
//配置集群节点主节点竞选的节点
cluster.initial_master_nodes: ["node-1", "node-2"]

启动集群节点

./elasticsearch -Epath.data=data1 -Epath.logs=log1 -Enode.name=node-1 -d
./elasticsearch -Epath.data=data2 -Epath.logs=log2 -Enode.name=node-2 -d
./elasticsearch -Epath.data=data3 -Epath.logs=log3 -Enode.name=node-3 -d

查看集群健康信息：
curl http://localhost:9200/_cluster/health
curl http://localhost:9200/_cat/healthv=true
查看节点列表
curl http://localhost:9200/_cat/nodes
查看节点信息
curl http://localhost:9200/_nodes/transportpretty

错误

################################################################
## IMPORTANT: JVM heap size
################################################################
##
## The heap size is automatically configured by Elasticsearch
## based on the available memory in your system and the roles
## each node is configured to fulfill. If specifying heap is
## required, it should be done through a file in jvm.options.d,
## and the min and max should be set to the same value. For
## example, to set the heap to 4 GB, create a new file in the
## jvm.options.d directory containing these lines:
##
## -Xms4g
## -Xmx4g
##
## See https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html

################################################################
# 按自己机器内存情况配置

解决方法：
创建es用户

创建es 用户
useradd es
创建es用户密码  changeme
passwd es
分配es用户 安装文件夹权限
chown -R es elasticsearch-7.12.0
切换到es 用户
su es

启动报错“Error: Could not find or load main class org.elasticsearch.tools.java_version_checker.JavaVersionChecker”
解决方法：因为elasticsearch目录在root下面，将elasticsearch安装文件拷贝到es用户目录下
启动报错“AccessDeniedException[/home/es/elasticsearch-7.12.0/config/elasticsearch.yml]”
解决方法：因为elasticsearch目录没有权限，读取不到配置文件，授权操作一下

chown -R es elasticsearch-7.12.0
启动报错 “ERROR: [2] bootstrap checks failed”
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

解决方法：

修改配置文件
vim /etc/sysctl.conf
在文件最后加上
vm.max_map_count=262144
保存文件后 刷新文件生效
sysctl -p
