Ansible批量修改密码

共计 5105 个字符，预计需要花费 13 分钟才能阅读完成。

因为线上存在大量主机即将密码过期（每三个月过期），急需一个批量改密码的脚本好拯救我弱小的身板

这里记录下使用user模块修改用户密码

批量修改playbook

[xadocker@jenkins-master xadocker]$ cat play.yaml
---
- hosts: all
  gather_facts: false
  remote_user: xadocker
  become_user: root
  become: yes
  tasks:
    - name: chanage_user_pass
      user: name={{ item.name }} password={{ item.chpass | password_hash('sha512') }}  update_password=always
      with_items:
        - { name: 'root', chpass: "{{ root_passwd }}" }
        - { name: 'xadocker', chpass: "{{ xadocker_passwd }}" }

inventory主机清单

[xadocker@jenkins-master xadocker]$ cat hosts
[web]
192.168.237.119 root_passwd='hfs8HO903hk*&^' xadocker_passwd='%hkjh(hj23hsleF'
192.168.237.114 root_passwd='hfs8HO903hGGEk*&^' xadocker_passwd='%hkjh(hj23hslfhF'
192.168.237.115 root_passwd='hfs8HO90GG3hk*&^' xadocker_passwd='%hkjh(hj23hslefwF'

题外话：host里的密码如何批量生成，因为在使用ansible时，并未自动生成密码，所以需要提前生成密码并写在hosts中

1.安装pwgen密码生成器

[xadocker@jenkins-master xadocker]$ sudo yum install pwgen -y

2.生成密码

[xadocker@jenkins-master xadocker]$ pwgen -cny 20

思路：收集主机地址列表写入hosts中，这种东西在你管理批量主机时是首要的工作之一，别说你没有记录，或没有别的方式收集到（真的话那你就你个一个收集吧）

# host样例
[web]
192.168.237.119

[test]
192.168.237.114

[db]
192.168.237.115

3.使用shell脚本配合pwgen生成密码

[xadocker@jenkins-master xadocker]$ cat gen_hosts.sh 
#!/bin/bash
cat hosts| while read line;
do
    echo $line | egrep '^\[|^#|^$' && continue
    echo $line root_passwd=\'`pwgen -cny 20`\' xadoker_passwd=\'`pwgen -cny 20`\'
done

4.生成hosts

[xadocker@jenkins-master xadocker]$ bash gen_hosts.sh 
[web]
192.168.237.119 root_passwd='oShohje8Oa\T8eich9ie' xadoker_passwd='ua3aeShah^geiSail4uf'

[test]
192.168.237.114 root_passwd='aiv(ah4quaxa|u6Iej8o' xadoker_passwd='eequ`a7maem+eihaeG0A'

[db]
192.168.237.115 root_passwd='vieRa=u5vo7aeNgailoh' xadoker_passwd='thoh0AiLu5tu0uho~o)x'
