我已经使用以下命令安装了 Alternative PHP Cache：
pecl install apc
创建并复制到 /etc/php.d/ a apc.ini 如下：
; /etc/php.d/apc.ini
extension = apc.so
Directive Local Value
apc.cache_by_default On
apc.canonicalize On
apc.coredump_unmap Off
apc.enable_cli Off
apc.enabled On

apc.ttl 7200
apc.use_request_time On

然后在 /etc/ 中的 php.ini 中添加以下行：extension=apc.so
如果我尝试加载网站的主页和一些我认为已在缓存中的其他页面，系统可以正常工作……但当我尝试加载其他页面（如 home.com/wp-admin）时，我收到一条错误消息，提示未找到该页面！怎么了？谢谢帮助

答案1
听起来像与 zend 优化器发生冲突。
您可以通过在 php.ini 文件中注释掉此行来禁用 zend：
zend_extension ="path/to/extension_dir/zend_optimizer.so"
更新：
php.ini 设置看起来不错。
有一个关于文件包含的错误报告APC 3.1.8 导致致命的 php 错误： failed to open stream: No such file or directory
我会尝试删除 APC 并重新编译版本 3.1.7，看看错误是否消失。
