Shell腳本自動源碼包安裝LA/NMP架構詳解（贈軟件包+腳本）

腳本環境

1.linux centos 7 系統
2.光盤鏡像文件已掛載
3.系統可鏈接外網
4.軟件包下載連接
lamp 連接：https://pan.baidu.com/s/1x6PTj_aUN2P1DfGGOKe90g
提取碼：3w8g
lnmp 連接：https://pan.baidu.com/s/1lr4x1yUFVtDsUWDYJePIyw
提取碼：8427

實驗步驟

1.上傳軟件包到Linux系統/opt目錄下

方法一：掛載 方法二：經過Xftp軟件上傳

2.編寫腳本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
#下載mysql,php軟件包（此處註釋了，去#開啓）
#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!"
#下載編譯工具包
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 "未安裝" | wc -l`
#判斷編譯工具是否下載完成
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
#
#人機交互輸入腳本名稱
read -p "please input script name (la/nmp): " install
echo -e "\e\t\t\t[32m installing $install ... \e[0m"
#延遲1秒,讓用戶看到本身輸入的腳本
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"

#將用戶輸入的腳本名導入e.sh文件

3.編寫腳本lnmp.sh

vim lnmp.sh

4.賦予腳本權限

chmod +x *.sh

5.執行腳本

./lnmp.sh

6.驗證腳本

舒適提示：

1.在上面提供了全部軟件安裝包，能夠直接使用。也可使用腳本中連接下載，腳本中爲節約時間已經註釋點了，去#號便可（不推薦聯網下載，下載慢還容易出錯）！
2.此腳本只是爲了給你們學習參考，不建議直接拷貝使用，容易出錯。想要的，能夠去我上傳資料中下載，解壓直接使用。(http://down.51cto.com/data/2458725)
3.此腳本不推薦工做時使用，太繁瑣了，可做爲新手練習寫shell 腳本的一個項目。我相信，經過此腳本練習，對你們的shell腳本編寫能力會大大提升！
4.爲避免一個腳本內容過長，編寫起來不方便，採用了2個腳本。package.sh腳本是軟件包下載和解壓，lnmp.sh腳本是在執行package.sh腳本後安裝配置服務。（難點是學習2個腳本的結合點）
5.此腳本重難點:(1) 2個腳本結合部分
(2) 修改配置文件要對sed,awk熟練運用
(3) 全部服務安裝與配置之間的檢查，順序整理
(4) 對 echo " , ' , -e, 知識掌握與區別
