安装ELK

一、安装前环境配置

1、卸载centos8自带jdk1.8
yum -y remove java-1.8.0*
2、安装openjdk11
sudo dnf install java-11-openjdk-devel
3、提示：请使用root用户安装

二、安装Elasticsearch（在线安装）

https://www.elastic.co/guide/en/elasticsearch/reference/7.10/rpm.html#rpm-repo

1、使用rpm命令导入源的 GPG：

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

2、vim修改vim /etc/yum.repos.d/elasticsearch.repo粘贴下面的内容到文件中：

[elasticsearch-7.x]
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=1
autorefresh=1
type=rpm-md

:wq!

3、安装 Elasticsearch 软件包，输入：

sudo dnf install elasticsearch

4、启动服务并验证状态：

sudo systemctl enable elasticsearch.service --now
sudo systemctl start elasticsearch.service
sudo systemctl status elasticsearch.service

● elasticsearch.service - Elasticsearch

5、验证 Elasticsearch 是否运行

[root@dahouzi-elk jvm]# curl -X GET "localhost:9200/"
{
  "name" : "dahouzi-elk",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "IyK8r1PQRM2MCk5z00BbLQ",
  "version" : {
    "number" : "7.10.1",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "1c34507e66d7db1211f66f3513706fdf548736aa",
