一、基础入门 未来主体是传统行业利用互联网技术,以云端用人工智能的方式处理大数据。从早期的All In One(所有应用部署在一台机器上)的简单应用,到后期集群、高可用、缓存、消息队列、配置中心、主从分离、负载均衡、大数据存储等尖端技术的复杂应用,对运维的技术专业
# This controls how ansible handles multiple --tags and --skip-tags arguments # on the CLI. If this is True then multiple arguments are merged together. If # it is False, then the last specified argument is used and the others are ignored. # This option will be removed in 2.8. #merg...
在include中使用循环如下: (注意:在included的任务中含有自己的with_loop值,会覆盖掉特定的item的值,如果既要使用include的item又要使用当前任务的item,必须使用set_fact去创建一个别名) -include:test.yml with_items: -1 -2 -3 在test.yml中: -set_fact:outer_loop="{{item}}" -debug:msg="outer item...
If your environment doesn't have a problem securing # stdout from ansible-playbook (or you have manually specified no_log in your # playbook on all of the tasks where you have secret information) then you can # safely set this to True to get more informative messages. #display_args_to_...

只有当TASKS种的action的执行状态是changed时,才会触发notify handler的执行。下面的脚本执行两次,执行结果是不同的:第一次执行是,tasks的状态都是changed,会触发两个handler第二次执行是,第一个task的状态是OK,那么不会触发handlers"call by /tmp/hosts",第二个task的状态是changed,触发了handler"call by /tmp/ho...

Ansible allows Jinja2 loops and conditionals intemplatesbut not in playbooks. You cannot create a loop of tasks. Ansible playbooks are pure machine-parseable YAML. When to quote variables (a YAML gotcha) If you start a value with{{foo}}, you must quote the whole expression to create ...
