模块：对于服务模块来讲，还可以通过service_facts模块收集有关系统上服务的信息，并将该信息存储在ansible_facts[services]变量中。...- name: populate service facts service_facts: - debug: var: ansible_facts.services - name: serviers...facts hosts: webs tasks: - name: collect service status facts service_facts: - name...┌──[root@control]-[~/web] └─$ansible-playbook service_facts.yaml --syntax-check playbook: service_facts.yaml...# needed for ansible_facts.packages - name: Check which packages are installed package_facts: no_log

7.设置Facts缓存 当我们用ansible-playbook执行Playbook的时候，我们会发现，默认第一个Task都是GATHERING FACTS，这个过程就是Ansible收集每台主机的Facts...当然如果我们的Playbook中不需要Facts信息，可以在Playbook中设置gather_facts: False来提高Playbook的效率： ---- hosts: 10.0.108.2gather_facts...但是如果我们既想每次执行Playbook的时候都能收集Facts信息，又想加速这个收集过程，这时候可以设置Facts的缓存。...smart表示默认收集Facts，但Facts已有的情况下不会收集，即使用缓存Facts； implicit表示默认收集Facts，要禁止收集，必须使用gather_facts: False； explicit...表示默认不收集，要显式收集，必须使用gather_facts: Ture； 在使用Facts缓存时(即设置为smart)，Ansible支持两种Facts缓存:redis和jsonfile。
