mcrypt.h not found. Please reinstall libmcrypt”的解决方法

CentOS源不能安装libmcrypt-devel，由于版权的原因没有自带mcrypt的包。

有两种方法解决，一种是使用第三方源，这样还可以使用yum来安装，简单方便，坏处是第三方源多少有中不可靠的感觉。

解决办法一
1、安装第三方yum源
wget http://www.atomicorp.com/installers/atomic
sh ./atomic
2、使用yum命令安装
yum  install  php-mcrypt  libmcrypt  libmcrypt-devel 

解决办法二、
使用php mcrypt 前必须先安装Libmcrypt

libmcrypt源码安装方法：

cd /usr/local/src
wget http://softlayer.dl.sourceforge.net/sourceforge/mcrypt/libmcrypt-2.5.8.tar.gz
tar -zxvf libmcrypt-2.5.8.tar.gz
cd /usr/local/src/libmcrypt-2.5.8
./configure --prefix=/usr/local
make
make install

```
