Linux下PHP安装mcrypt扩展模块笔记
本文向大家介绍Linux下PHP安装mcrypt扩展模块笔记，包括了Linux下PHP安装mcrypt扩展模块笔记的使用技巧和注意事项，需要的朋友参考一下
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
