ArangoDB – 系统要求
ArangoDB – 系统要求
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;中央处理器: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) 的实例,内存为 1GB,一个 CPU 的处理能力为 2.2 GHz。本教程中的所有 arangosh 命令都针对 ArangoDB 版本 3.1.27 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 为许多操作系统和发行版预先构建。更多细节请参考 ArangoDB 文档。如前所述,对于本教程,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看到在输出结束时保存的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
输出
Reading package lists... Done Building dependency tree Reading state information... Done The following package was automatically installed and is no longer required: grub-pc-bin Use 'sudo apt autoremove' to remove it. The following NEW packages will be installed: arangodb3 0 upgraded, 1 newly installed, 0 to remove and 17 not upgraded. Need to get 55.6 MB of archives. After this operation, 343 MB of additional disk space will be used.
按Enter。现在安装 ArangoDB 的过程将开始 –

当 ArangoDB 的安装即将完成时,会出现以下屏幕 –
在这里,您将被要求为 ArangoDB根用户提供密码。仔细记下来。
出现以下对话框时选择是选项 –
当您在上述对话框中单击是时,将出现以下对话框。在此处单击是。
您还可以使用以下命令检查 ArangoDB 的状态 –
# sudo systemctl status arangodb3
输出
