Ansible为几个任务注册字典或动态变量

在Ansible中，我有两个单独的任务来获取redhat 6和7的现有服务列表，它们注册到一个变量，然后我有另一个任务来停止这些服务如果我使用相同的变量，它会被最后一个任务覆盖，所以它不会阻止任何事情。Ansible为几个任务注册字典或动态变量

有没有区分两种结果的方法？但只能使用一项任务来停止服务？我尝试了动态var名称或创建一个字典，但没有工作。

感谢

- name: Get registered services 
     command: bash -c "chkconfig --list | awk '{print $1}'" 
     register: loaded_services_{{ansible_distribution_major_version}} 
     when: ((ansible_os_family == "RedHat") and (ansible_distribution_major_version == "6")) 
     changed_when: False 
     tags: test 

    - name: Get registered services 
     command: bash -c "systemctl list-unit-files | grep enabled | cut -d. -f1" 
     register: loaded_services_{{ansible_distribution_major_version}} 
     when: ((ansible_os_family == "RedHat") and (ansible_distribution_major_version == "7")) 
     changed_when: False 
     tags: test 

    - name: shutdown unnecessary services 
     service: name={{ item }} enabled=no state=stopped 
     with_items: "{{ disable_services | intersect(loaded_services_{{ansible_distribution_major_version}}.stdout_lines)}}" 
     when: ansible_os_family == "RedHat" and ansible_distribution_major_version == "6"

尝试用块，第一个以这种方式：

- block: 
    - name: Get registered services 
     command: bash -c "chkconfig --list | awk '{print $1}'" 
     register: loaded_services 
     changed_when: False 
     tags: test 
    when: ((ansible_os_family == "RedHat") and (ansible_distribution_major_version == "6")) 

    - block: 
    - name: Get registered services 
     command: bash -c "systemctl list-unit-files | grep enabled | cut -d. -f1" 
     register: loaded_services 
     changed_when: False 
     tags: test 
    when: ((ansible_os_family == "RedHat") and (ansible_distribution_major_version == "7")) 

    - name: shutdown unnecessary services 
    service: name={{ item }} enabled=no state=stopped 
    with_items: "{{ disable_services | intersect(loaded_services.stdout_lines)}}" 
    when: ansible_os_family == "RedHat" and ansible_distribution_major_version == "6" 
    tags: 
     - harden 
     - test 
    ignore_errors: yes

如果doesn't工作，尝试在这个其他方式：

- block: 
    - name: Get registered services 
     command: bash -c "chkconfig --list | awk '{print $1}'" 
     register: loaded_services 
     changed_when: False 
     tags: test 

    - name: shutdown unnecessary services 
     service: name={{ item }} enabled=no state=stopped 
     with_items: "{{ disable_services | intersect(loaded_services.stdout_lines)}}" 
     tags: 
     - harden 
     - test 
     ignore_errors: yes 

    when: ((ansible_os_family == "RedHat") and (ansible_distribution_major_version == "6")) 

    - block: 
    - name: Get registered services 
     command: bash -c "systemctl list-unit-files | grep enabled | cut -d. -f1" 
     register: loaded_services 
     changed_when: False 
     tags: test 

    - name: shutdown unnecessary services 
     service: name={{ item }} enabled=no state=stopped 
     with_items: "{{ disable_services | intersect(loaded_services.stdout_lines)}}" 
     tags: 
     - harden 
     - test 
     ignore_errors: yes 

    when: ((ansible_os_family == "RedHat") and (ansible_distribution_major_version == "7"))

有趣的是与选项一，变量仍然被跳过程序覆盖:(“loaded_services”：“跳过”：true）...选项二将工作没有块（每个使用不同的变量），但这正是我试图避免的 – Kenneth
