　　1.利用dm-crypt来创建加密文件系统。编写shell脚本（安装和卸载两个shell脚本）
　　2.编写ansible，playbook文件
　　3.编写python脚本
　　首先编写shell脚本
　　install.sh
　　

#!/bin/sh
sudo apt-get install dmsetup cryptsetup
sudo modprobe dm-crypt
echo "dd if=/dev/zero of=/home/prod/secret.img bs=1M count=100"
sudo dd if=/dev/zero of=/home/prod/secret.img bs=1M count=100
echo "----------------------------------------------------------"
echo "losetup /dev/loop0 ~/secret.img"
sudo losetup /dev/loop0 /home/prod/secret.img
echo "----------------------------------------------------------"
sudo losetup /dev/loop0
echo "----------------------------------------------------------"
echo "cryptsetup -y  create myEncryptedFilesystem /dev/loop0"
sudo cryptsetup -y  create myEncryptedFilesystem /dev/loop0
echo "----------------------------------------------------------"
sudo dmsetup ls
echo "----------------------------------------------------------"
echo "mkfs.ext3 /dev/mapper/myEncryptedFilesystem"
sudo mkfs.ext3 /dev/mapper/myEncryptedFilesystem
echo "----------------------------------------------------------"
sudo mkdir /mnt/myEncryptedFilesystem
echo "----------------------------------------------------------"
echo "mount /dev/mapper/myEncryptedFilesystem /mnt/myEncryptedFilesystem"
sudo mount /dev/mapper/myEncryptedFilesystem /mnt/myEncryptedFilesystem
echo "----------------------------------------------------------"
sudo df -h /mnt/myEncryptedFilesystem
　　
　　uninstall.sh
　　#!/bin/sh
sudo umount /mnt/myEncryptedFilesystem
sudo cryptsetup remove myEncryptedFilesystem
sudo dmsetup ls
sudo losetup -d /dev/loop0
sudo rm -rf secret.img
　　编写playbook文件
　　

---
- hosts: cmdb
user: prod
sudo: True
tasks:
- name: install dm-crypt
action: command sh /home/prod/svnrepos/uninstall.sh编写python脚本　　
　　

import commands
(status, output) = commands.getstatusoutput('ansible-playbook playbook.yml')
print status, output
　　首先执行install.sh脚本



　　需要输入密码。
　　然后执行python脚本运行uninstall.sh 卸载
　　执行python脚本的结果如下
