LINUX 安装elasticsearch RPM

1、安装公开签名，设置环境变量

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

ES_PATH_CONF=/path/to/my/config ./bin/elasticsearch

2、在/etc/yum.repos.d/下创建elasticsearch.repo

cd /etc/yum.repos.d/
touch elasticsearch.repo

elasticsearch.repo文件内容　

[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

3、接下来就可以安装了

sudo yum install --enablerepo=elasticsearch elasticsearch

4、创建系统索引

action.auto_create_index: .monitoring*,.watches,.triggered_watches,.watcher-history*,.ml*

5、系统启动时自动启动

sudo chkconfig --add elasticsearch

6、修改配置文件

vim /etc/elasticsearch/elasticsearch.yml

#network.host: 192.168.0.1 改为
network.host: 0.0.0.0
# 在文件末尾写入
# 初始主节点IP地址
cluster.initial_master_nodes: ["你自己的IP地址"]
# 子节点IP地址
discovery.seed_hosts: ["你自己的IP地址"]
