1、安裝php

(1)獲得PHP源碼：php-5.4.1.tar.gz(最新版本為5.4.2)，保存到/usr/local目錄下。下載地址：http://cn.php.net/get/php-5.4.2.tar.gz/from/a/mirror。

(2)解壓縮源碼文件：

#tar -zvxf php-5.4.1.tar.gz

(3)安裝libxm12以及libXML2-devel，不然編譯源碼時會出現“Configure: error: xml2-config not

found. Please check your libxml2 installation.”問題。

#yum install -y libxml2 libxm12-devel

(4)編譯源碼：

#cd /usr/local/php-5.4.1

#./configure --prefix=/usr/local/php

--with-apxs2=/usr/local/apache2/bin/apxs --with-MySQL=/usr/local/mysql

#make

(5)安裝

#make install

2、配置PHP

(1)將PHP源碼包(/usr/local/php-5.4.1)中的php.ini-development文件復制到/usr/local/lib/下，更名為php.ini。

#cp /usr/local/php-5.4.1/php.ini-development /usr/local/lib/php.ini

(2)修改Apache配置文件(gedit

/usr/local/apache2/conf/httpd.conf)以支持對PHP的解析。如果httpd.conf中沒有下列語句，就將它們分別添加到LoadModule和AddType項的后面。

LoadModule php5_module modules/libphp5.so

AddType application/x-httpd-php .php

在DirectoryIndex index.html index.html.var一行后加入index.php，即改為：

DirectoryIndex index.html index.html.var index.php

重啟Apache服務器：

#/usr/local/apache2/bin/apachectl restart

(3)測試PHP：

在Apache服務器的文件根目錄(/usr/local/apache2/htdocs/)下新建一個PHP文件test.php，并輸入以下內容：

《？

phpinfo();

?>

在瀏覽器中輸入http://localhost/test.php，如果看到下圖，則表示已成功安裝了PHP。

以上參考《基于Linux的Web程序設計PHP網站開發》一書。
