优雅安装 Apache Ambari 3¶
背景
Apache Ambari 是开源的，用于部署、管理和监控 Hadoop 大数据集群的工具。有了它，就可以优雅地安装 Hadoop 集群。
今天我们先优雅地安装 Ambari，下次可以利用 Ambari 优雅地安装 Hadoop。
关键是优雅，不要在控制台上敲一堆命令，尤其是操作多台机器时，一旦敲错、漏命令，真是让人抓狂。我在 23 年的时候，写过几篇安装 Hadoop 集群的博客，当时是一行行命令敲的，太不优雅了。
好消息是，前阵子 Ambari 更新到了 3.0 大版本，支持 Rocky Linux 8 和 9 操作系统，提供官方安装包，且使用开源的 Apache Bigtop 作为大数据组件的安装源，不用受制于闭源的 Cloudera 提供的 HDP 源。
为了快速准备多台虚拟机，我们会用到 Vagrant 这款软件。当实验全部完成后，会快速销毁这些虚拟机。Vagrant 并不能真正的运行虚拟机，它要依赖于 VirtualBox、VMware 这些虚拟机 Hypervisor 来创建、运行和销毁。
前置条件
- 安装 Vagrant，用于快速创建、销毁虚拟机。
- 安装 VirtualBox，被 Vagrant 调用，用于实际创建和销毁虚拟机。
搭建实验环境¶
-
创建 Vagrantfile
在 C:\Users\许王伟\dev\vagrant\ambari 目录下新建一个文件，名叫 Vagrantfile。
Tip
按照你的习惯建工作目录就好，C:\Users\许王伟\dev\vagrant\ambari 是我的习惯。
Vagrantfile# -*- mode: ruby -*- # vi: set ft=ruby : VAGRANT_DISABLE_VBOXSYMLINKCREATE=1 Vagrant.configure("2") do |config| config.vm.box = "rockylinux/9" config.vm.box_version = "6.0.0" hosts_entries = <<-HOSTS 192.168.56.11 vm1 192.168.56.12 vm2 192.168.56.13 vm3 HOSTS (1..3).each do |i| config.vm.define "vm#{i}" do |node| node.vm.hostname = "vm#{i}" node.vm.network "private_network", ip: "192.168.56.1#{i}" node.vm.synced_folder ".", "/vagrant", disabled: true node.vm.provider "virtualbox" do |vb| vb.name = "vm#{i}" vb.cpus = 2 vb.memory = 8192 end node.vm.provision "shell", inline: <<-SHELL echo "Updating /etc/hosts" echo "#{hosts_entries}" >> /etc/hosts SHELL end end end -
启动虚拟机
进入控制台，确保当前处于 C:\Users\许王伟\dev\vagrant\ambari 目录下。在控制台中输入
Tip
我用的 PowerShell，也可以用 CMD，什么都行，只要到工作目录下执行命令就行。

免密登录配置
这一步要在 vm1 上生成公私钥，并且将公钥内容拷贝到所有机器上。

安装 Apache Ambari¶
-
创建 Ansilbe inventory
在家目录下新建一个文件 inventory.ini。其实，随便哪个目录下都行，按照个人习惯来就好。
-
创建 Ansible playbook
在家目录下新建一个文件 playbook.yml。把内容复制粘贴进去就行，不要纠结内容，除非你对 Ansible 感兴趣，那可以看看。

验证¶
在宿主机上打开浏览器，输入 http://192.168.56.11:8080 后回车就可以看到 Web 管理页面。用户名和密码都是 admin。
销毁实验环境¶
在虚拟机中输入 Ctrl + D 退出登录，然后在宿主机上的工作目录下执行下面的命令会删除所有实验的虚拟机。
总结¶
我们通过 Vagrant 快速创建了 3 台虚拟机，这 3 台虚拟机由 Vagrantfile 文件来定义。
接着，我们通过 vagrant ssh vm1 命令远程登录 vm1 虚拟机，以 vagrant 用户的身份，我们用 ssh-keygen 命令生成了公私钥，并通过 ssh-copy-id 将公钥拷贝到了所有主机，实现了从 vm1 虚拟机上以 vagrant 用户身份免密登录所有虚拟机的需求。
然后，在 vm1 虚拟机上，我们创建了 inventory.ini 和 playbook.yml 文件，并用 ansible-play 命令一键安装了 ambari-server 和 ambari-agent。
最后，我们在宿主机上，使用浏览器打开了 Ambari 的 Web 管理页面。
最后的最后，还学会了使用 vagrant destroy -f 命令销毁所有虚拟机。
