1.下载安装包

[root@localhost ~]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.5.3-linux-x86_64.tar.gz

2.解压配置

[root@localhost ~]# tar -xvf /root/soft/elasticsearch-8.5.3-linux-x86_64.tar.gz -C /usr/local/

[root@localhost ~]# cd elasticsearch-8.5.3/

3.修改系统参数

[root@localhost ~]# vim /etc/security/limits.conf
* soft nofile 65536 
* hard nofile 65536 
* soft nproc  65536 
* hard nproc  65536 

[root@localhost ~]# vim /etc/sysctl.conf 
vm.max_map_count = 655360

[root@localhost ~]# sysctl -p

4.创建es用户

[root@localhost ~]# groupadd es 
[root@localhost ~]# useradd -g es es

5.修改es配置文件

[root@localhost config]# pwd
/usr/local/elasticsearch-8.5.3/config
[root@localhost config]# vim jvm.options                                            （修改为自己机器合适的大小）
-Xms1g
-Xmx1g
