ansible学习之--简单学习笔记一

1.利用dm-crypt来创建加密文件系统。编写shell脚本

2.编写ansible，playbook文件

3.编写python脚本

首先编写shell脚本

#!/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

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

执行python脚本的结果如下
