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/ 目录下报错:
编译mcrypt时,报错:You need at least libmhash 0.8.15
执行 ./configure 编译源码,报错如下:
checking whether mhash >= 0.8.15... no
configure: error: "You need at least libmhash 0.8.15 to compile this program. http://mhash.sf.net/"
-
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
-
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
-
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
-
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
-
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
一通上面的操作之后,还是不行。
打开/etc/ld.so.conf,在文件之后,添加一行: /usr/local/lib
然后,执行 ldconfig ,重新编译即可
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(); ?>
