handlers执行的时候需要注意,虽然是在某个任务被触发的,但是它必须等到所有的task执行完成后,才会执行handlers里面被触发过的命令,如果在执行前,有另一个task执行失败了,那么被触发的handlers也不会执行。 tags标签 对任务指定标签后,我们在使用ansible-playbook执行的时候就可以指定标签来执行任务,不需要执行所有的任务,
以特定的层级目录结构进行组织的tasks、variables、handlers、templates、files等; role_name/ files/:存储由copy或script等模块调用的文件; tasks/:此目录中至少应该有一个名为main.yml的文件,用于定义各task;其它的文件需要由main.yml进行“包含”调用; handlers/:此目录中至少应该有一个名为main.yml的文件,用于定...

(七)、tasks列表和action 1、Play的主体部分是task列表,task列表中的各任务按次序逐个在hosts中指定的主机上执行,即在所有主机上完成第一个任务后再开始。在运行playbook时 (从上到下执行),如果一个host执行task失败, 整个tasks都会回滚,请修正playbook中的错误,然后重新执行,即Task的目的是使用指定的参数执行模块,...
