Arangodb 简明教程
ArangoDB - System Requirements
在本章中,我们将讨论 ArangoDB 的系统要求。
ArangoDB 的系统要求如下 -
-
装有 Ubuntu 的 VPS 服务器
-
RAM:1GB;CPU:2.2GHz
在本教程中的所有命令中,我们使用了一台 RAM 为 1GB 的 Ubuntu 16.04(xenial)实例,配备一个处理能力为 2.2GHz 的 CPU。并且本教程中的所有 arangosh 命令均针对 ArangoDB 版本 3.1.27 进行测试。
How to Install ArangoDB?
在本节中,我们将了解如何安装 ArangoDB。ArangoDB 已针对许多操作系统和发行版预构建。有关更多详细信息,请参阅 ArangoDB 文档。如前所述,对于本教程,我们将使用 Ubuntu 16.04x64。
第一步是下载其储存库的公钥 -
# wget https://www.arangodb.com/repositories/arangodb31/
xUbuntu_16.04/Release.key
Output

重点是,你应该看到 Release.key 保存于输出结尾处。
让我们使用以下代码行安装已保存的密钥 -
# sudo apt-key add Release.key
Output
OK
运行以下命令以添加 apt 存储库并更新索引 -
# sudo apt-add-repository 'deb
https://www.arangodb.com/repositories/arangodb31/xUbuntu_16.04/ /'
# sudo apt-get update
作为最后一步,我们可以安装 ArangoDB -
# sudo apt-get install arangodb3
