脚本环境

1.linux centos 7 系统
2.光盘镜像文件已挂载
3.系统可连接外网
4.软件包下载链接
lamp 链接：https://pan.baidu.com/s/1x6PTj_aUN2P1DfGGOKe90g
提取码：3w8g
lnmp 链接：https://pan.baidu.com/s/1lr4x1yUFVtDsUWDYJePIyw
提取码：8427

实验步骤

1.上传软件包到Linux系统/opt目录下

方法一：挂载 方法二：通过Xftp软件上传

2.编写脚本package.sh

vim package.sh

#!/bin/bash
# this is down package and tar shell!
#
cd /opt
echo -e "\e\t\t\t[34m mysql,php package downing 。。。\e[0m"
sleep 1
#下载mysql,php软件包（此处注释了，去#开启）
#wget http://dev.mysql.com/get/Downloads/MySQL-5.5.24/mysql-5.5.24.tar.gz &&wget http://php.net/distributions/php-5.6.11.tar.gz && echo "mysql,php package down finish!"
#下载编译工具包
yum -y install gcc gcc-c++ make cmake pcre perl bison gd libpng libpng-devel libaio-devel ncurses-devel libxml2-devel zlib-devel pcre-devel expat-devel openssl-devel libjpeg-devel fontconfig-devel bzip2-devel
bash=`rpm -q gcc gcc-c++ make cmake pcre perl bison gd libpng libaio-devel libpng-devel ncurses-devel libxml2-devel zlib-devel pcre-devel expat-devel openssl-devel | grep "未安装" | wc -l`
#判断编译工具是否下载完成
if [ $bash -eq 0 ];then
echo -e "\033\t\t\t[32m make tool down finish！\033[0m"
else
exit 0 && echo echo -e "\033\t\t\t[31m make tool down fail,check ! \033[0m"
fi
#
#人机交互输入脚本名称
read -p "please input script name (la/nmp): " install
echo -e "\e\t\t\t[32m installing $install ... \e[0m"
#延迟1秒,让用户看到自己输入的脚本
sleep 1
#
case $install in

[[ $? -eq 0 ]] && echo -e "\033[32m lnmp package tar success！\033[0m" || exit 0 && echo -e "\033[31m lnmp package tar fail,check! \033[0m"
;;

echo "请输入:lamp | lnmp "
exit 0
esac
#将用户输入的脚本名导入e.sh文件
echo "$install" >>/root/e.sh

3.编写脚本lnmp.sh

vim lnmp.sh

4.赋予脚本权限

chmod +x *.sh

5.执行脚本

./lnmp.sh

6.验证脚本

温馨提示：

1.在上面提供了所有软件安装包，可以直接使用。也可以使用脚本中链接下载，脚本中为节约时间已经注释点了，去#号即可（不推荐联网下载，下载慢还容易出错）！
2.此脚本只是为了给大家学习参考，不建议直接拷贝使用，容易出错。想要的，可以去我上传资料中下载，解压直接使用。(http://down.51cto.com/data/2458725)
3.此脚本不推荐工作时使用，太繁琐了，可作为新手练习写shell 脚本的一个项目。我相信，通过此脚本练习，对大家的shell脚本编写能力会大大提高！
4.为避免一个脚本内容过长，编写起来不方便，采用了2个脚本。package.sh脚本是软件包下载和解压，lnmp.sh脚本是在执行package.sh脚本后安装配置服务。（难点是学习2个脚本的结合点）
5.此脚本重难点:(1) 2个脚本结合部分
(2) 修改配置文件要对sed,awk熟练运用
(3) 所有服务安装与配置之间的检查，顺序整理
(4) 对 echo " , ' , -e, 知识掌握与区别
