How to get MCrypt and PHP to work with CentOS

I installed mcrypt on CentOS (via yum), but when I try to make a dl () call in A) I get a message in B).

  • A) dl (mcrypt.so) or die ('The Mcrypt module could not be loaded ['. $ Prefix. 'Mcrypt., PHP_SHLIB_SUFFIX.'] ');
  • B) Failed to load module Mcrypt [mcrypt.so]

Now I know that yum installed mcrypt, but I don't know where it put it in. May I find out? More importantly, how can I get the latest mcrypt installed working with my PHP system. Many threads suggest you recompile PHP (eg: http://forums.theplanet.com/index.php?showtopic=26527 ), but I don't know how to do this with CentOS. I have also played around with my library paths to no avail. Any help would be greatly appreciated.

Setting up

  • CentOS: Linux localhost.localdomain 2.6.18-128.1.6.el5 # 1 SMP Wed Apr 1 09:10:25 EDT 2009 x86_64 x86_64 x86_64 GNU / Linux
  • mcrypt: mcrypt-2.6.8-1.el5.x86_64
  • PHP: php-5.1.6-23.2.el5_3.x86_64

Thanks

Ok, I'm going to suggest some reasons why you can't use the package provided by the CentOS distributors (see here for an example.) I don't know CentOS, but I can give you a rough outline of the steps that are most likely to lead to successful building and installing the mcrypt module for PHP.



  • Get a copy of the PHP source that matches your compiled version of the distribution (CentOS may have a package for this)

  • Install PHP pacakges (maybe something like "php5-dev") as well as all dependencies to build PHP for your distribution (on Debian based systems this is done via apt-get build-dep php5

    , not sure if the correct spell for CentOS).

  • From the top level directory of the PHP source, cd to ext/mcrypt

    . In this directory, launch phpize

    (this should have been installed alongside the aforementioned CentOS equivalent php5-dev

    ). This will create a script configuration in ext/mcrypt

    which will allow you to create mcrypt as a shared module.

  • In the same directory, ext/mcrypt

    enter ./configure --help

    and review the options available to you. Since then, he is very similar to any other Unix application: configure

    , make

    , make install

    .
