选择需要安装的版本：https://www.elastic.co/cn/downloads/past-releases/

 

 

 

 下载：

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.7.0-linux-x86_64.tar.gz
#解压
tar -xzvf elasticsearch-7.7.0-linux-x86_64.tar.gz
#将解压文件夹移动到 /user/local/下，自定义
mv elasticsearch-7.7.0 /user/local/elasticsearch
cd /user/local/elasticsearch

　　

执行：

./bin/elasticsearch

修改config下的jvm.options文件

cd config/
vim jvm.options

　　在文件底部加上

-XX:+AssumeMP

　　docker参考链接：http://www.fecmall.com/topic/1171

运行：

adduser es
#赋予文件夹权限
chown -R es /user/local/elasticsearch/
#切换用户
su es
#需先开启防火墙对应端口，elasticsearch默认9200端口
#运行 elasticsearch
/usr/local/elasticsearch/bin/elasticsearch -d #-d 在后台以守护进程模式运行

查看： 

netstat -lntp

 

 或者运行：

curl 'http://localhost:9200/?pretty'

 

设置开机运行 转自 https://www.csdn.net/tags/NtjaAgxsMzU1MjQtYmxvZwO0O0OO0O0O.html
