第三篇 Elasticsearch 安装 - RPM方式

# 导入公钥
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
 
# 创建Elasticsearch的yum源文件
echo "[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" | sudo tee /etc/yum.repos.d/elasticsearch.repo
 
# 安装Elasticsearch
sudo yum install --enablerepo=elasticsearch elasticsearch
 
# 启动Elasticsearch服务
sudo systemctl start elasticsearch
 
# 设置Elasticsearch服务开机自启
sudo systemctl enable elasticsearch

这段代码展示了如何在基于RPM的系统上安装Elasticsearch。首先导入Elasticsearch的公钥，然后创建一个yum源文件，接着使用yum安装Elasticsearch，并启动及设置开机自启服务。
