安装准备

工具准备(连接访问linux系统的工具)

WindTerm，远程访问Linux系统，输入命令使用;
下载地址：
https://sh.goodwaysoft.com:8257/WindTerm_2.6.0_Prerelease_2_Windows_Portable_x86_64.zip
WinSCP，远程访问Linux系统，复制代码文件、修改Nginx配置项使用;
下载地址：https://sh.goodwaysoft.com:8257/WinSCP-6.1.1-Setup.exe
使用方法：
用WindTerm、WinSCP远程连接Linux系统
解压WindTerm后，双击运行WindTerm.exe
在会话页面，右键‘新建会话’
主机：(H) Linux系统IP地址；端口：(P) 22 默认端口，可修改；OneKey：设置Linux系统的用户名，密码
添加完成后，双击会话列表中的linux系统地址，进入linux命令页面；
注意：双击linux系统地址时，此处需要下拉选择设置的密码；
WinSCP远程连接Linux系统，在‘新建标签页’，添加Linux的访问方式，配置方式同WindTerm一样

搭建elasticsearch8.13.2

查看linux cpu类型,然后根据类型下载

uname -m
#结果是: Linux localhost.localdomain 3.10.0-1160.el7.x86_64 #1 SMP Mon Oct 19 16:18:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

官网下载

下载对应版本的elasticsearch

https://www.elastic.co/cn/downloads/past-releases/elasticsearch-8-13-2

复制安装包到Linux

使用WinSCP远程工具，把安装包复制到linux系统中

/opt

解压软件

cd /opt
# 解压缩
tar -zxvf elasticsearch-8.13.2-linux-x86_64.tar.gz

创建用户

Elasticsearch 不允许 root 用户直接运行，所以要创建新用户，在 root 用户中创建新用户。

useradd es #新增 es 用户
passwd es #为 es 用户设置密码,例`elasticadmin`
chown -R es:es /opt/elasticsearch-8.13.2 #文件夹所有者

userdel -r es #如果错了，可以删除再加

前置准备

每个进程可以打开的文件数的限制，进入文件夹/etc/security/，打开文件limits.conf，在文件末尾新增

es          hard    nproc     4096
es          soft    nproc     4096

打开文件/etc/sysctl.conf，设置一个进程可以拥有的 VMA(虚拟内存区域)的数量,默认值为 65536，在文件末尾新增

vm.max_map_count=655360

保存后执以下命令使配置生效  

sudo sysctl -p

第一个节点的配置文件

使用WinSCP远程工具，进入/opt/elasticsearch-8.13.2/config/目录下，双击打开elasticsearch.yml文件
注意此处可直接复制以下内容，粘贴覆盖替换原有的内容，如有疑问，可备份原有的elasticsearch.yml文件，在粘贴替换；

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /opt/elasticsearch-8.13.2/data
#
# Path to log files:
#
path.logs: /opt/elasticsearch-8.13.2/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
network.host: 127.0.0.1
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
cluster.initial_master_nodes: ["node-1"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Allow wildcard deletion of indices:
#
#action.destructive_requires_name: false
#----------------------- BEGIN SECURITY AUTO CONFIGURATION -----------------------
#
# The following settings, TLS certificates, and keys have been automatically      
# generated to configure Elasticsearch security features on 20-05-2024 07:00:37
#
# --------------------------------------------------------------------------------

# Enable security features
xpack.security.enabled: false

xpack.security.enrollment.enabled: true

xpack.security.http.ssl.enabled: false
xpack.security.transport.ssl.enabled: false

#----------------------- END SECURITY AUTO CONFIGURATION -------------------------

http.cors.enabled: true
http.cors.allow-origin: "*"

修改jvm.options文件，限制ES内存占用大小

使用WinSCP远程工具，进入到/opt/elasticsearch-8.13.2/config文件夹下，双击打开jvm.options文件

-Xms4g
-Xmx4g

启动elasticsearch

切换到es账号，使用WindTerm.exe工具，进入到/opt/elasticsearch-8.13.2文件夹下，启动es

cd /opt/elasticsearch-8.13.2
bin/elasticsearch -d

验证elasticsearch是否启动

使用WindTerm.exe工具，执行命令

curl 127.0.0.1:9200

或者直接在浏览器中输入：http://10.10.1.202:9200

重启elasticsearch

使用WindTerm.exe工具，执行命令

ps -ef|grep elasticsearch 
kill 10897

设置elasticsearch开机自启

1.使用WinSCP远程工具，进入到/etc/systemd/system文件夹，新建文件es.service
2.修改es.service文件

[Unit]
Description=Elasticsearch
After=network.target
 
[Service]
Type=simple
User=es
Group=es
ExecStart=/opt/elasticsearch-8.13.2/bin/elasticsearch
Restart=on-failure
 
[Install]
WantedBy=multi-user.target

4.设置开机自启 注册并启动启动服务

sudo systemctl enable es.service

(启动服务)

sudo systemctl start es.service

检查服务状态:

sudo systemctl status es.service

重启服务:

sudo systemctl restart es.service

检查服务状态:

sudo systemctl status es.service

关闭服务:

sudo systemctl stop es.service
