注册变量也可以在之后的play操作同一主机时被调用到,和上面讲的set_fact特性一样。注册变量中的信息是模块的返回值,这并不是我们自定义的信息,所以,如果想要在tasks中给变量自定义信息,并且在之后的play操作同一个主机时能够使用到之前在tasks中定义的变量时,则可以使用set_facts定义对应的变量。 9.常见内置变量详解 ansible中
11. host facts / cached set_facts Host Facts 是 Ansible 通过setup自动收集的系统信息,用于描述目标主机的状态 Cached Set Facts 是您通过 set_fact 动态设置并选择缓存的自定义变量 cached set_facts 指的是将获取到的变量缓存,可以与redis关联,或通过内置set_fact模块缓存变量,此配置较为复杂,不再详细描述 ...

connection plugins:连接插件,ansible和host之间通信 ansible优点 No client 不需要在被管控主机上安装任何软件 No server 不用单独启用服务,能使用直接运行,使用时直接运行命令 支持sudo 基于ssh工作,安全 幂等性:无改变重复操作自动跳过机制 提供一个功能强大、操作性强的Web管理界面和REST API接口——AWX平台 配置简单...
You can define different variables for each host individually, or set shared variables for a group of hosts in your inventory. For example, if all machines in the[Boston]group use ‘boston.ntp.example.com’ as an NTP server, you can set a group variable. TheHow to build your inventorypage...
If you load inventory files from both the playbook directory and the inventory directory, variables in the playbook directory will override variables set in the inventory directory. 主机变量[atlanta] host1 http_port=80 maxRequestsPerChild=808 host2 http_port=303 maxRequestsPerChild=909 组的变量[...

If set to True the bastion/jump host ssh settings should be present in ~/.ssh/config file, alternatively it can be set to custom ssh configuration file path to read the bastion/jump host settings. Default: None Ini: Section: [netconf_connection] Key: ssh_config Environment: Variable:...
