如果上述操作对应的Ansible中,也就是一份安装从库的playbook,内部不仅要在从库上执行相关命令,还需要跨机器到主库上执行一些相关命令,类似这种一个任务不是在当前机器执行,而是需要委派到其它机器上执行的操作,就需要用到delegate_to 如下示例,演示了在指定机器增加一条hosts记录解析 - name: add test domain to an...
Generally playbooks will stop executing any more steps on a host that has a task fail. Sometimes, though, you want to continue on. To do so, write a task that looks like this: -name:this will not be counted as a failurecommand:/bin/falseignore_errors:yes ...
