shell指令碼：一鍵安裝LAMP、LNMP指令碼

歷時三天邊寫邊測試，終於完成目前最長程式碼的指令碼，總共253行，在2臺機器安裝LAMP，LNMP都順利透過，指令碼可做為生產環境使用。

指令碼需要注意的地方：
1、指令碼適用於CentOS系統6.5以上，乾淨系統；如安裝過其他環境需要修改指令碼內容；
2、指令碼適用於：apache 2.4.x 版本；mysql5.5.x以上版本；php5.5.x以上版本；
3、mysql、php、apache、nginx安裝包事先要下載到/usr/local/src目錄下，如名字不對需要更改指令碼里的軟體包名稱；
指令碼安裝的版本為以下，如需其他名稱，請自行修改軟體安裝包名稱和對應的目錄名即可；
httpd-2.4.7.tar.gz 、mysql-5.6.25.tar.gz 、nginx-1.6.2.tar.gz、 php-5.6.8.tar.gz
4、指令碼沒有增加判斷，設定的環境為乾淨系統；

指令碼內容如下：
