十二章、LAMP環境搭建的自動化搭建
所謂自動化搭建當然是實現一定的自動化部署了，並且可以承受一定的大型的網站點選量，LAMP環境的部署完全可以使用自動化指令碼實現，這樣便達到了無人值守的安裝方式。
1、準備下列軟體
httpd-2.2.14.tar.gz
mysql-5.1.41.tar.gz
gd-2.0.35.tar.gz
php-5.2.11.tar.gz
freetype-2.3.10.tar.gz
jpegsrc.v7.tar.gz
libpng-1.2.41.tar.gz
下載好，上傳到/root/apmg_install.
2、編寫一個安裝指南install放在/root/apmg_install
下載後，tar zxvf apmg_install.tar.gz ;
cd apmg_install;
./setup.sh 自動完成安裝，時間大概10多分鐘
3、編寫httpd.sed檔案放在/root/apmg_install
目的是為了在apache的httpd.conf中加入相關的行。
檔案 httpd.sed內容：
/application/x-compress .Z/a
AddType application/x-httpd-php .php
4、編寫test.php放在/root/apmg_install
<?php
phpinfo();
?>
5、編寫測試指令碼放在/root/apmg_install/setup.sh
這個指令碼基於linux和freebsd，可能要經過多次測試才成功。
#!/bin/sh
#this is a script about *nix installing apache,php with gd2.write by sery(sery@163.com),in 2009-12-03

6、以上準備工作做好以後，執行setup.sh
執行完畢後，啟動apache，然後執行test.php測試
然後執行，setup許可權不夠賦予許可權。
遇到下面的錯誤提示，如果sh目錄存在且指令碼無誤，最可能是原因是在windows下寫的指令碼是dos格式的，放在Linux下編碼不識別，解決方法是使用dos2unix命令轉一下，即輸入： dos2unix 檔名
我們可以看到，飛快的執行程式呢？結果我們拭目以待。
還有一點特別提醒，我們編寫指令碼檔案的時候是在window條件下，雖然執行了轉換，但難免會有亂碼，所以一定要vi setup.sh檔案檢視，還要留心標點符號也要符合linux環境才行。如windows下的‘’“”要轉換為linux下的` ` 和” “。
編譯遇到了php5模組沒載入正確。查文件需要關閉selinux。
Vi /etc/sysconfig/selinux
把 SELINUX=enforcing 註釋掉：#SELINUX=enforcing ，然後新加一行為：
SELINUX=disabled 然後重啟從新編譯。
我們然後在編譯這次出現
幾乎都是ok啦，我們執行/usr/local/apache2/bin/apachectl start
編譯完畢我們測試一下：http://192.168.22.132/test.php
7、打包歸檔
cd /root切換到root
tar zcvf apmg_install.tar.gz apmg_install
這樣將打包好儲存起來，下次可以解包直接使用
