Ansible文件 + 终端统计输出

在 写文件的同时，再加一个 debug 任务，把统计信息直接打印在终端。这样你执行完 ansible-playbook 就能立刻看到成功/失败情况。

最终 Playbook：文件 + 终端统计

保存为 ping_baidu.yml：

- hosts: webservers
  become: no
  tasks:
    - name: Ping www.baidu.com from each host
      shell: ping -c 4 www.baidu.com
      register: ping_result
      ignore_errors: yes   # 即使失败也继续执行

    - name: Collect results with status
      set_fact:
        ping_summary: "{{ ping_summary | default([]) + ['===== ' + inventory_hostname + ' =====\n' + (ping_result.stdout | default('FAILED'))] }}"
        ping_success: "{{ (ping_success | default([])) + ([inventory_hostname] if ping_result.rc == 0 else []) }}"
        ping_failed: "{{ (ping_failed | default([])) + ([inventory_hostname] if ping_result.rc != 0 else []) }}"

- hosts: localhost
  gather_facts: no
  tasks:
    - name: Ensure result directory exists
      file:
        path: /tmp/ping_results
        state: directory
        mode: '0755'

    - name: Save all results into one file with summary
      copy:
        content: |
          {{ hostvars | dict2items | selectattr('value.ping_summary','defined') | map(attribute='value.ping_summary') | sum(start=[]) | join('\n\n') }}

          ===== SUMMARY =====
          Success hosts ({{ hostvars | dict2items | map(attribute='value.ping_success') | select('defined') | sum(start=[]) | length }}):
          {{ hostvars | dict2items | map(attribute='value.ping_success') | select('defined') | sum(start=[]) | join(', ') }}

          Failed hosts ({{ hostvars | dict2items | map(attribute='value.ping_failed') | select('defined') | sum(start=[]) | length }}):
          {{ hostvars | dict2items | map(attribute='value.ping_failed') | select('defined') | sum(start=[]) | join(', ') }}
        dest: /tmp/ping_results/all.log

    - name: Show summary in terminal
      debug:
        msg: |
          ===== SUMMARY =====
          Success hosts ({{ hostvars | dict2items | map(attribute='value.ping_success') | select('defined') | sum(start=[]) | length }}):
          {{ hostvars | dict2items | map(attribute='value.ping_success') | select('defined') | sum(start=[]) | join(', ') }}

          Failed hosts ({{ hostvars | dict2items | map(attribute='value.ping_failed') | select('defined') | sum(start=[]) | length }}):
          {{ hostvars | dict2items | map(attribute='value.ping_failed') | select('defined') | sum(start=[]) | join(', ') }}

执行

ansible-playbook -i /etc/ansible/hosts/inventory.ini ping_baidu.yml

终端输出示例

TASK [Show summary in terminal] ***********************************************
ok: [localhost] => {
    "msg": "===== SUMMARY =====\nSuccess hosts (1):\n10.0.19.207\n\nFailed hosts (1):\n10.0.19.208"
}

文件 /tmp/ping_results/all.log

同时也会保存完整的日志 + 统计。
