📅  最后修改于: 2020-11-28 13:08:31             🧑  作者: Mango

在本章中，我们将讨论ArangoDB的系统要求。

ArangoDB的系统要求如下-

  • 安装了Ubuntu的VPS服务器
  • 内存：1 GB;处理器：2.2 GHz

对于本教程中的所有命令，我们使用了一个Ubuntu 16.04(xenial)RAM 1GB实例，其中一个CPU的处理能力为2.2 GHz。并且本教程中的所有arangosh命令都针对ArangoDB 3.1.27版进行了测试。

如何安装ArangoDB?

在本节中，我们将看到如何安装ArangoDB。 ArangoDB是为许多操作系统和发行版预先构建的。有关更多详细信息，请参阅ArangoDB文档。如前所述，在本教程中，我们将使用Ubuntu 16.04×64。

第一步是下载其存储库的公钥-

# wget https://www.arangodb.com/repositories/arangodb31/
xUbuntu_16.04/Release.key

输出

重要的一点是，您应该在输出末尾看到Release.key 。

让我们使用以下代码行安装保存的密钥：

# sudo apt-key add Release.key

输出

OK

运行以下命令以添加apt信息库并更新索引-

# sudo apt-add-repository 'deb
https://www.arangodb.com/repositories/arangodb31/xUbuntu_16.04/ /'
# sudo apt-get update

最后一步，我们可以安装ArangoDB-

# sudo apt-get install arangodb3

输出

Need to get 55.6 MB of archives.
After this operation, 343 MB of additional disk space will be used.

按Enter键。现在，安装ArangoDB的过程将开始-

您还可以使用以下命令检查ArangoDB的状态-

# sudo systemctl status arangodb3

输出
