linux安装Elasticsearch

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.1.1.tar.gz

tar -zxvf elasticsearch-7.1.1.tar.gz -C /usr/local/

说明：从5.0开始 elasticsearch 安全级别提高了不允许采用root帐号启动所以我们要添加一个用户用来启动 elasticsearch

1.关闭防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service //禁止防火墙开机启动

2.创建es用户

useradd es

3.目录权限赋予给es用户

chown -R es:es /usr/local/elasticsearch-7.1.1/

4.切换至es用户

su es

5.执行命令，更改Elasticsearch Network Host

vi /usr/local/elasticsearch-7.1.1/config/elasticsearch.yml

6.执行命令

sh /usr/local/elasticsearch-7.1.1/bin/elasticsearch
或
sh /usr/local/elasticsearch-7.1.1/bin/elasticsearch -d  //后台启动

7.查看进程

ps -ef|grep elasticsearch

8.验证下服务是否正常运行

curl  http://192.168.120.135:9200

9.浏览器访问
