PHP安装mcrypt.so报错 mcrypt.h not found 的解决方法
PHP安装mcrypt.so报错 mcrypt.h not found 的解决办法
报错内容：configure: error: mcrypt.h not found. Please reinstall libmcrypt
网上搜索了很多，包括自带的 yum install libmcrypt libmcrypt-devel，这个是没有效果的。
去SourceForget下载libmcrypt http://sourceforge.net/projects/mcrypt/files/Libmcrypt/ ，最新版是mcrypt 2.6.7.gz。下载下来安装仍旧报错libmcrypt没有找到！
继续测试，最后安装成功，感觉是版本太高。
方法（关键点在用 2.5.7版本）：
#使用wget可以通过以下路径下载wget ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/attic/libmcrypt/libmcrypt-2.5.7.tar.gz #解压tar -zxvf libmcrypt-2.5.7.tar.gz #进入目录cd libmcrypt-2.5.7 #编译（默认安装到/usr/local/lib/）./configure --prefix=/usr/local/libmcrypt #执行安装make && make install
再回到PHP-5.5.13解压缩的ext目录的mcrypt里面
phpize./configure --with-php-config=/usr/local/php5/bin/php-config \--with-libmcrypt=/usr/lib/libmcryptmakemake testmake installvim /etc/php.ini #加入extension=mcrypt.so
