Linux使用 RPM 安装 Elasticsearch

参考网站：https://www.elastic.co/guide/en/elasticsearch/reference/8.5/rpm.html#rpm-repo

1.导入Elasticsearch GPG签名密钥

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

2.创建软件源

cat > /etc/yum.repos.d/elasticsearch.repo << EOF
[elasticsearch]
name=Elasticsearch repository for 8.x packages
baseurl=https://artifacts.elastic.co/packages/8.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=0
autorefresh=1
type=rpm-md
EOF

3.安装

　　1.使用上面的软件源进行安装

yum install --enablerepo=elasticsearch elasticsearch

　　2.离线RPM包安装【离线环境】

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.5.2-x86_64.rpm
rpm --install elasticsearch-8.5.2-x86_64.rpm

4.配置开机自启

systemctl daemon-reload
systemctl enable elasticsearch.service

5.查看运行是否正常

curl --cacert /etc/elasticsearch/certs/http_ca.crt -u elastic https://localhost:9200

6.配置外网访问

vi /etc/elasticsearch/elasticsearch.yml

cluster.name: my-application
node.name: node-1
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 127.0.0.1
http.host: 0.0.0.0
http.port: 9200
http.cors.enabled: true
http.cors.allow-origin: "*"
discovery.seed_hosts: ["127.0.0.1","[::1]"]
cluster.initial_master_nodes: ["node-1"]
#以前有的配置有则修改剩下的不要动

7.配置防火墙

firewall-cmd --zone=public --add-port=9300/tcp --permanent 
firewall-cmd --zone=public --add-port=9200/tcp --permanent
systemctl restart firewalld.service

 8.访问 https://ip:9200/【注意是https】

　　账号: elastic

　　密码：安装过程中提示的那个密码
