SOLVED mcrypt php extension

[Nirjonadda]

mcrypt php extension are not supported to install in PHP 7.2, So now how to enable this Mcrypt PHP extension?

 

[cPanelKenneth]

Hi,

The PHP developers deprecated mcrypt in version 7.1, and removed support in version 7.2. Applications should use either sodium or openssl for encryption needs.

It may be possible to install mcrypt via PECL.

How does this affect software as Wordpress? How do we enable mcrypt for php 7.2 using PECL without breaking EasyApache 4?

Hello,

WordPress does not require mcrypt, so you shouldn't face any issues with WordPress unless specific third-party WordPress plugins make use of it. If you do decide to install the mcrypt PECL module for PHP 7.2, you'd need to do so using the following commands:

yum install libmcrypt
yum install libmcrypt-devel
/opt/cpanel/ea-php72/root/usr/bin/pecl install channel://pecl.php.net/mcrypt-1.0.1

Thank you.

Thank you.

Dear All,

I tried to setup mcyrpt php extension to php 7.2 on cpanel module installers page.
I got the following error message:
"Failed to download pecl/mcrypt within preferred state "stable", latest release is version 1.0.1, stability "snapshot", use "channel://pecl.php.net/mcrypt-1.0.1" to install
install failed"

I also tried the code written by cPanelMichael, but that also failed.
Indeed the last command did manage to run but reported these errors:

Can you help me how to solve this issue? I rewrote all my crypting to openssl but 3rd party apps still use mcryt.
Thank you

I tried to setup mcyrpt php extension to php 7.2 on cpanel module installers page.

Installing that PECL module using cPanel or WHM isn't supported because it's not released as a STABLE PECL module. The maintainers have only released the "snapshot" build of the module at:

PECL :: Package :: mcrypt

configure: error: mcrypt.h not found. Please reinstall libmcrypt. ERROR: `/root/tmp/pear/mcrypt/configure --with-php-config=/opt/cpanel/ea-php72/root/usr/bin/php-config --with-mcrypt' failed

It looks like the "yum install libmcrypt-devel" command referenced in my last response incorrectly included a space after the hyphen. I've corrected it so that it correctly shows:

yum install libmcrypt-devel

Can you run this command and then try running the PECL install command again to see if that solves the issue?

Thank you.

Did land on an error:

Hello @Zoltan Szabo,

It looks like your system is missing the EPEL YUM repo, which is required if you want to install that package. Here's a third-party URL with instructions on how to enable it:

EPEL - Fedora Project Wiki

Thank you.

Dear All,
The suggested solution worked right then. Now let me just SUM up what you need to install mcrypt extension to php 7.2 on Cpanel.
RPM link is for (Centos 7)! For other systems please see link in previous comments.

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum install libmcrypt
yum install libmcrypt-devel
/opt/cpanel/ea-php72/root/usr/bin/pecl install channel://pecl.php.net/mcrypt-1.0.1

I hope this helps others with same problem

Hello @Zoltan Szabo,

I'm glad to see the installation succeeded. I've marked this thread as solved.

Thanks!

@cPanelMichael Please can you let me know that what does mcrypt extension and why this support removed in php 7.2? So mcrypt extension no more used/needed or not important?

Hi,

I wanted to install mcrypt for PHP7.2 on cpanel and the above instructions seem to be godsent.

However I am facing issues.. I am getting an error when i run the install libmcrypt command


I get the error Requires: libc.so.6(GLIBC_2.14)(64bit)

Note that I also did a yum install libc.so.6 and that installation was successful. Even after that yum install libmcrypt fails with same error message

Hello,

I'm unable to reproduce this on a test system running CentOS 7 64-bit. Can you try running "yum update" first to make sure your existing packages are updated? Additionally, please let us know the output from the commands below:

rpm -qa|grep glibc
ls -al /etc/yum.repos.d

Thank you.

This is not an issue - I asked my component provider to send me update version of component so that I don't need mcrypt. Thanks so mcuh
