php - Zend OpCache 显示在 phpinfo() 中，但没有执行任何操作

Question

我正在使用 PHP 5.3.27 运行 VPS 环境。安装并配置了 Zend Opcache，但它实际上并没有缓存任何东西。它缓存的唯一文件是 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):

有一些罕见的东西:

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

它说您只缓存了 1 个文件。可能是 PHP 在某个时候重新启动或者它正在创建不同的进程
