The above is the installed yum history.um.
I installed the mcrypt extension module with yum The previous version is 7.0.2, but the additional mcrypt is 7.0.7.
I think it's because of this version, but the problem is that running results in a Call to undefined function mcrypt_create_iv() error.
I don't know how to reset the old 7.0.2 version of the repository.

Is there no problem if I install mcrypt with the existing version 7.0.2? In order to do that, please answer me how to set up the storage.
