学习了两周linux shell脚本，终于写出一个mysql自动化安装脚本。加上今天一整天的测试，可以正常执行安装mysql 5.5.40. 其他版本还没有测试。现分享一下。也请高手指点一下。执行该脚本的前提是：

环境介绍：

1、redhat 6.3 x64，最小化安装

2、RAM: 2G,HD:30G

3、关闭selinux

4、配置好yum源（我使用自己配置的源）

5、打开ssh，病配置好iptables，允许远程登录访问。

6、所需软件和文件：

   cmake-2.8.10.1.tar.gz

bison-3.0.tar.gz

zlib-1.2.7.tar.gz

mysql-5.5.40.tar.gz

my.cnf   //老师共享的文件

脚本内容：

#!/bin/bash

echo "step one: create folder and mount packages"

if [ -d /mnt/share ]

then

  echo "find it,don‘t need to create it."

else

   mkdir -p /mnt/share

     if [[ $? = 0 ]]

      then 

         echo "create it successfully!"

      else

        echo " can‘t create this folder!pls check out!"

       fi

   mount -t cifs -o username=swen02,password=autozhao01! //172.16.11.20/LAMP-all-software /mnt/share

fi

echo "step two: create mysql installation path"

if [ -d /project/class2 ]

then

   echo "find it, don‘t need to create it."

else

    mkdir -p /project/class2/

 if [[ $? = 0 ]]

      then

         echo "create it successfully!"

      else
