How to install mcrypt on CentOS 7.6?

Posted October 12, 2019 3.5k views
CentOS

This php script I am using requires mcrypt but the mcrypt module is depreciated and no longer available.

I tried yum -y install epel-release and yum -y install php-mcrypt but this doesn’t work.

Are there any other ways to install mcrypt?

Hey, @umijs

I managed to get this installed on my droplet using the following commands:

sudo yum install epel-release

sudo yum install libmcrypt-devel

If you are running the default PHP installation you will want to run the following command as well.

sudo yum install php-mcrypt

Also you will need to find which is your main php.ini file and add or uncomment the following line:

extension=mcrypt.so

Let me know how it goes.

    Doesn’t Work

    sudo yum install php-mcrypt

    Last metadata expiration check: 0:23:26 ago on Thu 30 Apr 2020 12:52:33 PM UTC.
    No match for argument: php-mcrypt
    Error: Unable to find a match: php-mcrypt

    Any ideas?

      Hello, @gotoplus

      Did you installed the EPEL repository?

      sudo yum install epel-release

      If the EPEL repository is installed you should be able to install the mcrypt extension without getting the unable to find a match error message.

      Let me know how it goes.

      Regards,
      Alex

        Yes did that several times to be sure same result

        sudo yum install epel-release

        Last metadata expiration check: 0:02:10 ago on Sun 17 May 2020 02:32:02 AM UTC.
        Package epel-release-8-8.el8.noarch is already installed.
        Dependencies resolved.
        Nothing to do.
        Complete!

        Then

        sudo yum install php-mcrypt
