一个简单的shell脚本—–实现虚拟机实验环境的简单配置

亲自写过shell脚本后才发现，这玩意真是太方便了，当你想把一些琐碎的、细节性的小指令一次性来完成时，脚本无疑是最好的选择，方便、快捷，关键是真是懒人必备啊。

由于安装的centos6.5是最小化安装，且是实验环境，即安装在vmware workstations上面，在首次安装完成后，配置完IP地址的相关信息后，就做了一个初始的快照，以便下次实验完后，可以通过快照快速还原系统。

但是由于实验环境的要求，例如防火墙、SELinux、光盘挂载、yum源配置等，都是最常需要修改的选项，并且由于最小化安装，系统里并没有vim编译工
具和man手册的查询，所以导致每次还原快照后，还要处理这些琐碎的问题。为此，我就专门写了这么一个小脚本，内容并不复杂，但是也是一种学习过程，发出
来和大家一起分享一下，顺便求指教

代码：

#!/bin/bash

# Config some simple order when the system start

# Create by phoenix

# Specify the path

server=/etc/init.d

yum=/etc/yum.repos.d

mountdir=/media/cdrom

selinux=/etc/selinux/config

# stop the iptabes and set it cant start when the system start

$server/iptables stop /dev/null

if [ "$?" = "0" ]; then

 chkconfig iptables off

 chkconfig ip6tables off

 echo "1# The iptables stop successfully"

 echo "1# The iptables stop failed"

# shutdown the selinxu system

setenforce 0 sed -e s/^SELINUX=enforcing/SELINUX=disabled/g $selinux $selinux.bak 

mv -f $selinux.bak $selinux 

echo "2# The selinux system is disabled"

# Mount the CD-ROM

mount |grep sr0 /dev/null

if [ ! "$?" = "0" ]; then

 if [ ! -e $mountdir ]; then

 mkdir -p $mountdir /dev/null

 else

 mount /dev/cdrom $mountdir /dev/null

 echo "3# The CD-ROM is mounting successfully"

 echo "3# The CD-ROM is already mounted" 

# Config the source of yum

if [ -e $yum/CentOS-Base.repo ];then

 mv -f $yum/CentOS-Base.repo $yum/CentOS-Base.repo.bak /dev/null

 echo "4# Starting config the source of yum"

 sleep 3 

 sed -e s/^enabled=0/enabled=1/g $yum/CentOS-Media.repo $yum/CentOS-Media.repo.bak 

 mv -f $yum/CentOS-Media.repo.bak $yum/CentOS-Media.repo /dev/null

yum clean all /dev/null echo "5# The source of yum configed successfully"

# Modify the code of language

echo "#LANG=zh_CN.UTF-8" /etc/sysconfig/i18n

echo "6# The language is modify successfully"

# Install the tools "VIM" and "MAN"

echo "7# Starting install vim and man,please wait......"

sleep 3

yum install vim man -y /dev/null

# Reboot the system when all the work is done

echo "######### All work is done ########"

sleep 2

echo "Please wait the syatem restart......"

sleep 2

init 6
