1. 安装jdk

4.1. 说明

我们使用到的软件及程序运行的环境均依赖JDK 8，我们使用的版本是jdk-8u212-linux-x64.tar.gz。Oracle官网的下载地址需要注册账号，但在GitHub下载会比较方便，下载地址为https://github.com/frekele/oracle-java/releases/download/8u212-b10/jdk-8u212-linux-x64.tar.gz

4.2. yml脚本

---
- hosts: all
  remote_user: root
  vars_files:
    - ../vars.yml

  tasks:
  - name: mkdir jdk directory  #创建安装目录
    file: path={{ JDK_DIR }} state=directory mode=0755
  - name: copy and unzip jdk  #解压安装
    unarchive: src={{ PLAYBOOK_DIR }}/files/jdk-8u212-linux-x64.tar.gz dest={{ JDK_DIR }}
  - name: set env  #设置环境变量, ansible使用non-login shell所以~/.bashrc生效的
    lineinfile: dest=~/.bashrc insertafter="{{ item.position }}" line="{{ item.value }}" state=present
    with_items:
    - { position: EOF, value: "export JAVA_HOME={{ JDK_DIR }}/jdk1.8.0_212" }
    - { position: EOF, value: "export JRE_HOME=${JAVA_HOME}/jre" }
    - { position: EOF, value: "export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib" }
    - { position: EOF, value: "export PATH=$JAVA_HOME/bin:$PATH" }
  - name: chmod bin  #修改执行权限
    file: dest={{ JDK_DIR }}/jdk1.8.0_212/bin mode=0755 recurse=yes
  - name: enforce env  #刷新环境变量
    shell: source ~/.bashrc

4.3. 运行ansible-playbook

ansible-playbook -i /etc/ansible/hosts jdk/main.yml
