写一个安装jdk的playbook

好的，我可以为你编写一个安装JDK的Ansible Playbook，以下是代码：

- name: Install JDK 
  hosts: all
  become: yes
  vars:
    jdk_version: "11.0.11"
    jdk_home: "/usr/java/latest"
  tasks:
    - name: Download JDK
      get_url: 
        url: "https://download.java.net/java/GA/jdk{{ jdk_version }}/9/GPL/openjdk-{{ jdk_version }}_linux-x64_bin.tar.gz"
        dest: "/tmp/openjdk-{{ jdk_version }}_linux-x64_bin.tar.gz"
    - name: Create JDK dir
      file: 
        path: "{{ jdk_home }}"
        state: directory
    - name: Extract JDK tarball
      unarchive: 
        src: "/tmp/openjdk-{{ jdk_version }}_linux-x64_bin.tar.gz"
        dest: "{{ jdk_home }}"
        remote_src: yes
        extra_opts: [--strip-components=1]
    - name: Set JDK environment variables
      lineinfile:
        path: /etc/profile
        line: "export JAVA_HOME={{ jdk_home }}"
      become: yes
    - name: Load JDK environment variables
      shell: source /etc/profile

这个Playbook会下载JDK，创建JDK目录，解压JDK并设置环境变量。你可以根据自己的需要修改变量和路径。
