php安装mcrypt扩展

查了一下资料使用 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（https://bugzilla.redhat.com/show_bug.cgi?id=621268）RHEL 不打算添加PHP的mcrypt 的支持

Thanks for the report.

We are not planning to ship mcrypt support for PHP.

解决方案：

从php 官网下载新的php 5.3 源码包后http://www.php.net/releases/，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

[root@weekend109 php-5.5.36]# cd ext/mcrypt

[root@weekend109 mcrypt]# phpize
Configuring for:
PHP Api Version:         20090626
Zend Module Api No:      20090626
Zend Extension Api No:   220090626

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

----------------------------------------------------------------------
Libraries have been installed in:
   /home/zzq/software/php-5.5.36/ext/mcrypt/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify 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 variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during 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 for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

Build complete.
Don't forget to run 'make test'.

Installing shared extensions:     /usr/lib/php/modules/

如果make && make install 报错/home/zzq/software/php-5.5.36/ext/mcrypt/mcrypt.c:283: error: ‘PHP_FE_END’ undeclared here (not in a function)
make: *** [mcrypt.lo] Error 1

源码有错执行这个：

[root@weekend109 mcrypt]# sed -i 's|PHP_FE_END|{NULL,NULL,NULL}|' ./*.c
[root@weekend109 mcrypt]# sed -i 's|ZEND_MOD_END|{NULL,NULL,NULL}|' ./*.c

编辑php.ini

[root@weekend109 mcrypt]# vim /etc/php.ini

加入mcrypt.so，      mcrypt.so默认在/usr/lib/php/modules/里面

extension_dir = "/usr/lib/php/modules/"
extension = "mcrypt.so"

用

php -m

能查看到mcrypt就成功了
