十二章、LAMP环境搭建的自动化搭建
所谓自动化搭建当然是实现一定的自动化部署了，并且可以承受一定的大型的网站点击量，LAMP环境的部署完全可以使用自动化脚本实现，这样便达到了无人值守的安装方式。
1、准备下列软件
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
下载好，上传到/root/apmg_install.
2、编写一个安装指南install放在/root/apmg_install
下载后，tar zxvf apmg_install.tar.gz ;
cd apmg_install;
./setup.sh 自动完成安装，时间大概10多分钟
3、编写httpd.sed文件放在/root/apmg_install
目的是为了在apache的httpd.conf中加入相关的行。
文件 httpd.sed内容：/application\/x-compress .Z/a\ \ AddType application/x-httpd-php .php
4、编写test.php放在/root/apmg_install
<?php
phpinfo();
?>
5、编写测试脚本放在/root/apmg_install/setup.sh
这个脚本基于linux和freebsd，可能要经过多次测试才成功。
#!/bin/sh #this is a script about *nix installing apache,php with gd2.write by sery(),in 2009-12-03
#define some variables http_prefix=/usr/local/apache2 php_prefix=/usr/local/php

#install jpeg if [ ! -d /usr/local/jpeg ] then tar zxvf jpegsrc.v6.tar.gz cd jpeg-6 ./configure --prefix=/usr/local/jpeg make make install cd .. rm -rf jpeg-6 echo “gpeg install is ok!” fi
#install libpng if [ ! -d /usr/local/libpng ] then tar zxvf libpng-1.2.31.tar.gz cd libpng-1.2.31 ./configure --prefix=/usr/local/libpng make make install cd .. rm -rf libpng-1.2.31 echo “libpng install is ok!” sleep 5 fi

if [ ! -f /usr/include/png.h ] then ln -s /usr/local/libpng/include/png.h /usr/include fi
#install gd2 if [ ! -d /usr/local/gd2 ] then tar zxvf gd-2.0.35.tar.gz cd gd-2.0.35 ./configure --prefix=/usr/local/gd2 --with-freetype=/usr/local/freetype --with-png=/usr/local/libpng --with-jpeg=/usr/local/ jpeg make make install cd .. rm -rf gd-2.0.35 echo “gd2 install is ok!” sleep 2 fi
#install php.apache must be installed in /usr/local/apache2 if [ ! -d /usr/local/php ] then tar zxvf php-5.3.6.tar.gz cd php-5.3.6 ./configure --prefix=$php_prefix --with-gd=/usr/local/gd2 --with-apxs2=$http_prefix/bin/apxs --enable-mbregex --enable-bcmath --with-mysql --with-zlib-dir --enable-mbstring=all --with-pdo-mysql --with-freetype=/usr/local/freetype make make install cp php.ini-dist $php_prefix/lib/php.ini cd .. rm -rf php-5.3.6 echo “php with gd2 install is ok!” sleep 2 fi

else echo “this is other os,please modify the script” exit 1
fi
6、以上准备工作做好以后，执行setup.sh
执行完毕后，启动apache，然后运行test.php测试
然后执行，setup权限不够赋予权限。
遇到下面的错误提示，如果sh目录存在且脚本无误，最可能是原因是在windows下写的脚本是dos格式的，放在Linux下编码不识别，解决方法是使用dos2unix命令转一下，即输入： dos2unix 文件名
我们可以看到，飞快的执行程序呢？结果我们拭目以待。
还有一点特别提醒，我们编写脚本文件的时候是在window条件下，虽然执行了转换，但难免会有乱码，所以一定要vi setup.sh文件查看，还要留心标点符号也要符合linux环境才行。如windows下的‘’“”要转换为linux下的' ' 和" "。
编译遇到了php5模块没加载正确。查文档需要关闭selinux。
Vi /etc/sysconfig/selinux
把 SELINUX=enforcing 注释掉：#SELINUX=enforcing ，然后新加一行为： SELINUX=disabled 然后重启从新编译。
我们然后在编译这次出现
几乎都是ok啦，我们执行/usr/local/apache2/bin/apachectl start
编译完毕我们测试一下：
7、打包归档
cd /root切换到root
tar zcvf apmg_install.tar.gz apmg_install
这样将打包好保存起来，下次可以解包直接使用
