我已经在我的Ubuntu 13.04服务器盒上运行了APC已经有一段时间了。几天前，有些地方出了问题，现在它表现得非常奇怪。我会把它解决。
我的PHP配置文件位于/etc/php5/mods-available。 PHP5的所有配置目录（/etc/php5/cli/conf.d，/etc/php5/fpm/conf.d等）都符号链接到/etc/php5/conf.d/，而/etc/php5/mods-available符号链接到php -i。如果我从shell运行/etc/php5/cli/conf.d/*，我会返回apc

的配置文件，这应该与配置文件完全相同。我的问题的相关部分是：
apc.enabled这会将选项/etc/php5/fpm/conf.d显示为开启。但是，我的phpinfo.php（上面的链接）显示了PHP5-FPM的配置（来自apc.enabled），将此选项显示为Off。事实上，php（cli）的命令行版本和我的webserver（fpm）上运行的版本使用完全相同的符号链接配置文件。
我的APC似乎是缓存，但它表现得很奇怪。在我清空缓存并在我的服务器上的Wordpress安装上重新加载一些页面之前，我会看到页面立即被缓存。现在，它几个小时都停留在相同的Hits和Misses数字上，我可以尽可能多地刷新，没有任何变化。
0选项在apc.php上显示为20-apc.ini（关闭），但它似乎至少在做某事。操作码缓存和用户缓存中都有文件。它表现得很奇怪，我从PHP返回了很多矛盾的设置。我在这里不知所措。这是extension=apc.so

如果有人需要任何其他配置文件或部分配置文件，我会留意这个帖子，请告诉我。
