安装／配置


debian/ubuntu php5 (>= 5.4.0~rc6-1) has introduced two new commands:
php5enmod and php5dismod

# install the extension
sudo apt-get install php5-mcrypt
# you can see that it's installed by the presence of the .ini file
cat /etc/php5/mods-available/mcrypt.ini
# enable it
sudo php5enmod mcrypt
# reload Apache to make use of the extension
sudo service apache2 reload

Also on Ubuntu, make sure you actually have php5-mcrypt installed. You can install it with:

sudo apt-get install php5-mcrypt

If you get any errors, you may need to enable the 'universe' repository, explained here:

Using PHP version "PHP Version 5.3.10-1ubuntu3.4" and Ubuntu 12.0.4 on Apache2...

Make sure you have mcrypt installed and active on your php5 install. Use "sudo apt-get install php5-mcrypt" to install, that should sort the issue.

On ubuntu 8 (hardy), the mcrypt library seems to be here.

/usr/lib/php5/20060613/mcrypt.so

So I just created mcrypt.ini in /etc/php5/conf.d and added this one liner.

extension=mcrypt.so

To make sure that mcrypt doesn't fail to load when
using Windows XP , Apache 2 and php 5, even if all the required procedure to install it has been accomplished already, copy libmcrypt.dll, which is normally in the php main directory, into the php\ext directory.

PROBLEM: cannot load mcrypt extension. please check your php configuration

I have done as suggested by the contributor before me and copied libmcrypt.dll from F:\wamp\bin\php\PHP52~1.8
to C:\WINDOWS\system32 . This did not work on it's own. I found other advice as follows and now mcrypt is working.

OTHER ADVICE:

Go to F:\wamp\bin\php\PHP52~1.8\php.ini
change ;extension=php_mcrypt.dll
to      extension=php_mcrypt.dll 
(ie. remove ; )

now go to the following 2 files and do the same:
F:\wamp\bin\php\PHP52~1.8\phpForApache.ini 
F:\wamp\bin\apache\APACHE~1.11\bin\php.ini

Please adjust the directory location per your own installation.

On Windows installations, for the dynamic extension (extension=php_mcrypt.dll) to load properly, you must copy libmcrypt.dll from your PHP root folder (e.g. C:\PHP) to the following location:

C:\WINDOWS\system32

With this done, the dynamic extension will load up just fine.
