如果托管节点上开启了SElinux,你需要安装libselinux-python,这样才可使用Ansible中与通常我们使用 ssh 与托管节点通信,默认使用 sftp.如果 sftp 不可用,可在 ansible.cfg 配置文件中配置成 scp 的方式. 在托管节点上也需要安装 Python 2.4 或以上的版本.如果版本低于 Python 2.5 ,还需要额外安装一个模块: 客户端...
ansible是新出现的自动化运维工具,基于Python开发,集合了众多运维工具(puppet、cfengine、chef、func、fabric)的优点,实现了批量系统配置、批量程序部署、批量运行命令等功能。ansible是基于模块工作的,本身没有批量部署的能力。真正具有批量部署的是ansible所运行的模块,ansible只是提供一种框架。主要包括: (1)、连接插件co...

Use the Python SSH implementation (Paramiko) to connect to targets The paramiko transport is provided because many distributions, in particular EL6 and before do not support ControlPersist in their SSH implementations. This is needed on the Ansible control machine to be reasonably efficient with conne...

Ansible可能会在未来推出类似于run_once_when_condition_true的功能,但现在并没有(截止2021年2月)。 变通的方式: run_once和when同时出现会导致以下BUG:如果第一个host满足when条件那么BUG不触发,否则task被跳过(就是因为在第一个host上when条件未满足)。
