下载解压

 root@ubuntu-2204:~# hostnamectl set-hostname es-single && bash
 root@es-single:~# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.13.1-linux-x86_64.tar.gz
 root@es-single:~# tar xf elasticsearch-8.13.1-linux-x86_64.tar.gz -C /usr/local/

修改配置

 root@es-single:~# ln -sv /usr/local/elasticsearch-8.13.1 /usr/local/elasticsearch
 root@es-single:~# grep -v '#' /usr/local/elasticsearch/config/elasticsearch.yml

修改内存配

root@es-single:~# echo 'vm.max_map_count=262144' >> /etc/sysctl.conf 
root@es-single:~# sysctl -p 
root@es-single:~# vim /usr/local/elasticsearch/config/jvm.options
 ...
 ## -Xms4g
 -Xms128m
 ## -Xmx4g
 -Xmx128m

创建用户

从es7.X以后版不允许以root启动服务，需要委创建专用的用户

 root@es-single:~# useradd -r elasticsearch

目录权限更改

 root@es-single:~# mkdir -p /data/es-{data,logs}
 root@es-single:~# chown -R elasticsearch.elasticsearch /data/
 root@es-single:~# chown -R elasticsearch.elasticsearch /usr/local/elasticsearch/

启动 Elasticsearch服务

 root@es-single:~# echo 'PATH=/usr/local/elasticsearch/bin:$PATH' > /etc/profile.d/elasticsearch.sh
 root@es-single:~# . /etc/profile.d/elasticsearch.sh
 #不能以root用户运行，切换用户
 root@es-single:~# su - elasticsearch
 $ elasticsearch

验证服务

 root@es-single:~# curl 192.168.139.241:9200
