我正在测试剧本
以下剧本可以安装apache并启动服务：
- hosts: apacheweb
user: ansibleuser
become: yes
gather_facts: no
tasks:
- name: Install the apache web server
yum: pkg=httpd state=latest
notify: Start HTTPD
handlers:
- name: Start HTTPD
systemd: name=httpd state=started enabled=yes
但不是以下内容，因为它确实安装了httpd软件包，但没有启动该服务并启用它。
- hosts: apacheweb
user: ansibleuser
become: yes
gather_facts: no
tasks:
- name: Install the apache web server
yum: pkg=httpd state=latest
notify: Start HTTPD
- name: verify that the web service is running
command: systemctl status httpd
register: result
- debug: var=result
handlers:
- name: Start HTTPD
systemd: name=httpd state=started enabled=yes
错误输出：

我创建的第二本剧本可能有什么问题？
Start HTTPD由于任务verify that the web service is running失败，启动服务的处理程序未运行。
在每个主机上，一次播放中的所有任务完成后，处理程序仅运行一次。
在您的剧本中，有三个任务。尽管处理程序已通过第一个任务通知，但Install the apache web serveransible仅在完成该播放中的所有三个任务后才运行处理程序。
当任务在主机上失败时，先前通知的处理程序将不会在该主机上运行。
第二个任务的失败使处理程序无法在该主机上运行，因此该服务未启动。
如果您希望运行处理程序而与任务失败无关，则可以force_handlers: True在游戏中进行设置。
