	版本	arc-pro-dc01	arc-pro-dc02	arc-pro-dc03	arc-pro-dc04	arc-pro-dc05	arc-pro-dc06	arc-pro-dc07	arc-pro-dc08	arc-pro-dc09
Ansible	2.9.27	✅

説明：

每個服務器的 IP 均是靜態的
每個服務器的防火牆都已關閉
每個服務器的 SELINUX 已經禁用
每個服務器均存在一個管理員用户 admin，該用户可以免密碼執行 sudo 命令；
在 arc-pro-dc01 機器上，可以使用 admin 用户免密碼 ssh 到其他機器；
服務器之間的時間同步；
所有操作均使用 admin 用户完成；
每個服務的 /etc/hosts 文件均包含如下內容：

10.0.0.13 arc-pro-dc01
10.0.0.14 arc-pro-dc02
10.0.0.15 arc-pro-dc03

JDK	8u461	✅	✅	✅	✅	✅	✅	✅	✅	✅

1.4 下載安裝包

JDK 8 下載頁面：

8u211以及之後版本的下載頁面：https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html
8u202以及更早的版本下載頁面：https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html

該網站需要註冊登錄後才可以下載JDK。下載 jdk-8u461-linux-x64.tar.gz。

使用 admin 用户登錄 arc-pro-dc01 機器，創建目錄：/home/admin/ansible/jdk

將 jdk-8u461-linux-x64.tar.gz 上傳至 arc-pro-dc01 機器的 /home/admin/ansible/jdk 目錄下。

2. Ansible 文件

2.1 Ansible 目錄結構

説明：在 arc-pro-dc01 機器上，執行 ansible 命令的基礎目錄為 /home/admin/ansible

/home/admin/ansible/
├── ansible.cfg
├── hosts
└── jdk
    ├── install_jdk.yml
    └── jdk-8u461-linux-x64.tar.gz

2.2 ansible.cfg
