问题 I'm trying to turn these lines into something I can put in an ansible playbook: # Install Prezto files shopt -s extglob shopt -s nullglob files=( "${ZDOTDIR:-$HOME}"/.zprezto/runcoms/!(README.md) ) for rcfile in "${files[@]}"; do [[ -f $rcfile ]] && ln -s "$rcfile" "${ZDOTDIR:-$HOME}/.${rcfile##*/}" done So far I've got the following: - name: Link Prezto files file: src={{ item }} dest=~ state=link with_fileglob: - ~/.zprezto/runcoms/z* I know it isn't the same, but it would select the same

常用自动化运维工具： Ansible：python，Agentless，中小型应用环境 Saltstack：python，一般需要部署agent，执行效率高 Puppent：ruby，功能强大，配置复杂，适合大型环境 Fabric：python，agentlees Ansible特性：模块化：调用特定的模块，完成特定任务有Paramiko，PyYAML，Jinja2（模板语言）三个关键模块支持自定义模块基于Python语言实现部署简单，基于python和ssh，agentless 安全，基于openssh 支持playbook编排任务幂等性：一个任务执行1遍和执行n遍效果一样，不会因为重复执行而带来意外情况无须代理不依赖PKI（无须SSL）可使用任何编程语言写模块 YAML格式，编排任务，支持丰富的数据结构较强大的多层解决方案 Ansible架构： User通过主控端ansible控制host，ansbile里有一个host lnventory 主机清单记录着哪些主机是要被控制的，模块用于单一的命令，如果要执行多条任务就要用到playbook批量执行。要连接被控制主机就要用到Connection plugins连接插件基于SSH协议来执行。不仅可以使user用户来管理，也可以利用私有云或公有云开发接口来进行管理。 Ansible工作过程： 1、加载自己的配置文件
