如何在linux下安装php 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模块
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
测试效果如下,则表示mcrypt.so模块在php下加载成功。
