Question

我正在使用PHP 5.3.27运行VPS环境。安装和配置Zend Opcache但它实际上没有缓存任何东西。缓存的唯一文件是Opcache监视器。

0% memory usage
0% hit rate
total memory: 128.000MB
used memory: 276.266KB
free memory: 127.730MB
wasted memory: 0.000 bytes (0%)
number of cached files: 1
number of hits: 0
number of misses: 1
blacklist misses: 0
number of cached keys: 1
max cached keys: 7,963

这是配置（PHP -v）：

Answer 1

有一些罕见的事情：

number of cached files: 1
number of hits: 0
number of misses: 1

它表示您只缓存了1个文件。可能是PHP已经在某个时候重新启动，或者它正在创建不同的进程

Answer 2

我曾经遇到过这种情况。我试图重启php-fpm并且opcache再次工作。

Zend OpCache显示在phpinfo（）但没有做任何事情
