- 安装
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.3.1-linux-x86_64.tar.gz
tar -zxvf elasticsearch-*.tar.gz
- 启动
Run bin/elasticsearch (or bin\elasticsearch.bat on Windows)
3.坑点
- 不能用root用户运行es，切换普通用户就好。
groupadd elk # 创建用户组elk
useradd elk -g elk -p 111111 # 创建新用户elk，-g elk 设置其用户组为 elk，-p 111 设置其密码6个1
chown -R elk:elk /opt # 更改 /opt 文件夹及内部文件的所属用户及组为 elk:elk
su elk # 切换到非root用户elk下来
- 本机无法访问虚拟机的es
###修改es目录中config下elasticsearch.yml，末尾添加
network.host: 0.0.0.0
http.port: 9200
transport.host: localhost
transport.tcp.port: 9300
本机访问 虚拟机ip:9200出现如下即可
{

"cluster_name": "elasticsearch",
"cluster_uuid": "qaFgH4p_SpqUPOlThF3m_w",

}
访问前先关闭防火墙
CentOS 7.0默认使用的是firewall作为防火墙
- 查看防火墙状态
firewall-cmd --state
- 停止firewall
systemctl stop firewalld.service
- 禁止firewall开机启动
systemctl disable firewalld.service
