CentOS-扩展安装方法-php-yum-mcrypt

使用 yum install php-mcrypt 安装mcrypt扩展时会提示没有安装包

Setting up Install Process No package php-mcrypt available. Error: Nothing to do

mcrypt 是加密扩展库，加载了它可以用他里面自带的 22种加密解密算法

CentOS6 默认安装的是php5.3.2

默认的 redhat repos php中是没有 mcrypt 扩展的根据红帽的官方消息（）RHEL 不打算添加PHP的mcrypt 的支持Joe Orton 2010-08-05 04:47:17 EDT

Thanks for the report.

We are not planning to ship mcrypt support for PHP.

解决方法：

从php 官网下载新的php 5.3 源码包后，解压到本地目录进入解压目录下的 ext 目录后会发现有 mcrypt ，进入 mcrypt 目录

#cd /ext/mcrypt

注意：如果报 -bash:phpize not Found 那么 yum install php-devel 就可以使phpize进行动态编译安装扩展

#./configure -with-php-config=/usr/sbin/php/bin/php-config

#make && make install

出现：

If you ever happen to WANt to link against installed librariesin a given directory, LIBDIR, you must either use libtool, andspecify the full pathname of the library, or use the `-LLIBDIR'flag during linking and do at least one of the following:- add LIBDIR to the `LD_LIBRARY_PATH' environment variableduring execution- add LIBDIR to the `LD_RUN_PATH' environment variableduring linking- use the `-Wl,-rpath -Wl,LIBDIR' linker flag- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries formore information, such as the ld(1) and ld.so(8) manual pages.----------------------------------------------------------------------
