ubuntu安装elasticsearch7

1. 导入密钥

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
或者
curl -fsSL https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -

上面的命令应该输出OK，这意味着密钥已成功导入，并且来自此存储库的软件包将被视为受信任的。

2. 将Elasticsearch存储库添加到系统中

sudo sh -c 'echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" > /etc/apt/sources.list.d/elastic-7.x.list'

3. 更新储存库，执行安装命令

sudo apt update
sudo apt install elasticsearch

4. 启动elasticsearch

sudo service elasticsearch start

5. 测试是否启动成功

curl http://localhost:9200
