yum安装ELK之Elasticsearch

Elasticsearch官网：点这里

Elasticsearch二进制文件安装：点这里

好的，下面进入正题：

1.在 /etc/yum.repos.d/目录下自定义一个 es.repo 文件 写入

[elasticsearch]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=0
autorefresh=1
type=rpm-md

2.导入秘钥

rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

3.安装

sudo yum install --enablerepo=elasticsearch elasticsearch

4.更改配置-查询文件

whereis elasticsearch

5.这里只针对ELK环境下的单实例内网部署，不考虑开放公网的方式

vim /etc/elasticsearch/elasticsearch.yml


修改 network.host 为 127.0.0.1

对外访问端口为9200

elk场景使用无需开启外网访问，而增加复杂配置

端口随意

6.附上简单的操作命令

systemctl start elasticsearch
          status
          stop    

7.简单测试

curl http://localhost:9200/
