奇怪的PHP警告(无法加载动态库:无调试-非zts-20100525)

Question

我在apc.ini中临时设置了apc.ini，然后在终端中运行php -r "apc_clear_cache();“以清除APC缓存，但这是我得到的：

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

我在UbuntuServer12.04 (VPS)上运行PHP 5.4.3、Nginx 1.3.1和APC 3.1.10。你知道这些错误意味着什么吗？

这些错误意味着文件/opt/php5/lib/php/extensions/no-debug-non-zts-20100525/mcrypt.so不存在，而您的配置希望加载它。要么使文件存在(再次？)，要么修改PHP配置以不加载该文件。另外，/opt/php5不是一个Ubuntu -- PHP安装的标准位置，所以您已经对机器做了一些自定义操作--我首先回顾一下您在那里所做的事情。
