Ansible如何创建用户？

Ansilbe 提供了一个 user 模块，用于创建和管理用户；

但如何在创建用户的同时加秘设置用户密码呢？

Ansible用户创建

创建一个有登录shell 的用户,用户名是 bunian1：
name 指定创建的用户名
shell 指定用户登录时获得的shell
home 为用户创建 HOME 目录
state 指定是创建还是删除用户，当 state=absent 时，为删除用户

[root@localhost ansible]# ansible redis -m user -a 'name=bunian1 shell=/bin/bash  home=/home/bunian1/  state=present'

如何设置用户密码

用 ansible 设置用户的密码时，由于需要对传输的密码进行加密，所以要在主机安装python 的passlib 库。

利用 pip 安装 passlib：pip install passlib
生成的经过加密的密码(sha512 加密算法)

说明：在 Password 后输入我们的密码”xxxxx”，然后再按enter键

 python -c 'from passlib.hash import sha512_crypt; import getpass; print (sha512_crypt.encrypt(getpass.getpass()))'

PS F:\各组件相关说明\ansible相关> pip  install  passlib
