mcrypt is already build in for PHP 5.3.x for Windows, so you don't need to install libmcrypt.dllon the your server.
mcrypt 已经内置于适用于 Windows 的 PHP 5.3.x，因此您无需libmcrypt.dll在服务器上安装。
It's seems like php_mcrypt.dllextension is not loaded.
好像php_mcrypt.dll没有加载扩展。

wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
rpm -ivh epel-release-7-5.noarch.rpm
yum install --enablerepo="epel" php-mcrypt
with user 'root' or sudo
使用用户 'root' 或 sudo
with this, no need to add "extension=php_mcrypt.dll" in php.ini file
有了这个，不需要在 php.ini 文件中添加“extension=php_mcrypt.dll”
