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
