PHP添加mcrypt扩展模块 

系统环境：CentOS6.3
 
APACHE：httpd-2.4.2
 
PHP：php-5.3.21
 
一.安装mcrypt
 
1.下载Libmcrypt,mhash,mcrypt安装包 
 
libmcrypt-2.5.8.tar.gz
 
# wget http://sourceforge.net/project/showfiles.php?group_id=87941&package_id=91774&release_id=487459
 
mhash-0.9.9.tar.gz
 
# wget http://sourceforge.net/project/showfiles.php?group_id=4286&package_id=4300&release_id=645636
 
mcrypt-2.6.8.tar.gz
 
# wget http://sourceforge.net/project/showfiles.php?group_id=87941&package_id=91948&release_id=642101 
 
2 .先安装Libmcrypt
 
# tar -zxvf libmcrypt-2.5.8.tar.gz
 
# cd libmcrypt-2.5.8
 
# /usr/local/php5/bin/phpize #动态编译php模块，使其可以使用configure编译。
 
# ./configure
 
# make
 
# make install    # libmcript默认安装在/usr/local #
 
3.安装mhash
 
# tar -zxvf mhash-0.9.9.9.tar.gz
 
# cd mhash-0.9.9.9
 
# /usr/local/php5/bin/phpize 
 
# ./configure
 
# make
 
# make install
 
4.安装mcrypt
 
# tar -zxvf mcrypt-2.6.8.tar.gz
 
# cd mcrypt-2.6.8
 
# /usr/local/php5/bin/phpize 
 
# ./configure --with-php-config=/usr/local/php5/bin/php-config 
 
# make
 
# make install
 
安装完毕,按照编译安装后的提示
 
mcrypt.so模块会默认保存在 /usr/local/php5/lib/php/extensions/no-debug-zts-20090626/ 目录下
 
5.加载该模块到php
 
# vi /usr/local/php5/lib/php.ini
 
添加如下行：
 
extension = "/usr/local/php5/lib/php/extensions/no-debug-zts-20090626/mcrypt.so"
 
重启apache:
 
/usr/local/apache2/bin/apachectl restart
 
 
6.添加phpinfo功能，测试页面
 
添加以下内容info.php到/usr/local/apache2/htdocs/下,测试php模块是否加载.
 
# vi  /usr/local/apache2/htdocs/info.php
 
---------------
 
<?php
 
echo phpinfo();
 
?>
 
---------------
 
检查80端口是否打开
 
# lsof -i:80
 
浏览器输入 http://localhost/info.php
 
显示有如下测试页面内容, mcrypt.so模块即在PHP下加载成功
