PHP Warning: Unable to load dynamic library module.so

by · in Unix and Linux

Are you getting the PHP error below when loading any php website or script in CentOS? 

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/module.so' - /usr/lib64/php/modules/module.so: cannot open shared object file: No such file or directory in Unknown on line 0

It seems there are slight error in CentOS during PHP mcrypt installation. To fix the problem, follow the step below;

1. go to PHP setting directory 

# cd /etc/php.d

2. Edit the config file mcrypt.ini with your favorite editor 

#vi mcrypt.ini

3. Change module.so to mcrypt.so 

extension=mcrypt.so

Restart your apache service and boom, the error message is gone. I guess it should be fat finger error by the person who committed the code 😉
