This is a case of php72 installing mcrypt, you can modify the php version to your needs
It will be removed from the core code from PHP 7.2
If it is a new project, please use openssl_decrypt instead of mcrypt_encrypt for two-way encryption and decryption
yum install -y libmcrypt libmcrypt-devel mcrypt mhash
wget http://pecl.php.net/get/mcrypt-1.0.3.tgz
tar -zxvf mcrypt-1.0.3.tgz
cd mcrypt-1.0.3
