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
RAM:1 GB; CPU:2.2 GHz
对于本教程中的所有命令,我们使用了一个RAM 1GB的Ubuntu 16.04(xenial)实例和一个具有处理能力2.2 GHz.本教程中的所有arangosh命令都针对ArangoDB 3.1.27版进行了测试.
在本节中,我们将了解如何安装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 16.04x64.
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

重要的一点是,您应该看到发布.
让我们使用以下代码行安装保存的密钥 :
# sudo apt-key add Release.key
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
最后一步,我们可以安装ArangoDB :
# sudo apt-get install arangodb3
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,您将被要求提供ArangoDB root 用户的密码.请仔细注意.
当出现以下对话框时,选择是选项;
当您单击上面的对话框中的是时,将出现以下对话框.点击是.
您还可以使用以下命令检查ArangoDB的状态 :
# sudo systemctl status arangodb3
arangodb3.service - LSB: arangodb Loaded: loaded (/etc/init.d/arangodb3; bad; vendor pre set: enabled) Active: active (running) since Mon 2017-09-04 05:42:35 UTC; 4min 46s ago Docs: man:systemd-sysv-generator(8) Process: 2642 ExecStart=/etc/init.d/arangodb3 start (code = exited, status = 0/SUC Tasks: 22 Memory: 158.6M CPU: 3.117s CGroup: /system.slice/arangodb3.service ├─2689 /usr/sbin/arangod --uid arangodb --gid arangodb --pid-file /va └─2690 /usr/sbin/arangod --uid arangodb --gid arangodb --pid-file /va Sep 04 05:42:33 ubuntu-512 systemd[1]: Starting LSB: arangodb...

现在可以使用ArangoDB了.
调用arangosh终端,在终端输入以下命令 :
# arangosh
