I temporarily set apc.enable_cli=1 in apc.ini, then run php -r “apc_clear_cache();” in the terminal to clear APC cache but this is what I got:

PHP Warning:  PHP Startup: Unable to load dynamic library '/opt/php5/lib/php/extensions/no-debug-non-zts-20100525/mcrypt.so' - /opt/php5/lib/php/extensions/no-debug-non-zts-20100525/mcrypt.so: cannot open shared object file: No such file or directory in Unknown on line 0

I’m running PHP-FPM 5.4.3, Nginx 1.3.1 and APC 3.1.10 on an Ubuntu Server 12.04 (VPS). Do you have any idea of what these errors mean?

  1. The errors mean that the file /opt/php5/lib/php/extensions/no-debug-non-zts-20100525/mcrypt.so does not exist, while your PHP configuration wants to load it. Either make the file exist (again?), or modify your PHP configuration to not load the file. Also, /opt/php5 is not an Ubuntu-standard location for PHP installation, so you’ve done something custom to the machine — I’d start by reviewing your notes on what you did there.
