   If you ever happen to want to link against installed libraries                                                                                         [3/531]
   in a given directory, LIBDIR, you must either use libtool, and
   specify the full pathname of the library, or use the '-LLIBDIR'
   flag during linking and do at least one of the following:
      - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
        during execution
      - add LIBDIR to the 'LD_RUN_PATH' environment variable
        during linking
      - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
      - have your system administrator add LIBDIR to '/etc/ld.so.conf'
   
   See any operating system documentation about shared libraries for
   more information, such as the ld(1) and ld.so(8) manual pages.

   configuration option "php_ini" is not set to php.ini location
   You should add "extension=mcrypt.so" to php.ini
   

3. create a /etc/php/7.2/mods-available/mcrypt.ini

   ; configuration for php mcrypt module
   ; priority=20
   extension=mcrypt.so
   

4. create a symlink for mcrypt under fpm

   root@hydrogen:/etc/php/7.2# cd fpm/conf.d
   root@hydrogen:/etc/php/7.2/fpm/conf.d# ln -s ../../mods-available/mcrypt.ini 20-mcrypt.ini
   

5. restart fpm service

   root@hydrogen:/etc/php/7.2/fpm/conf.d# systemctl restart php7.2-fpm.service
