Opcache在php 5.5不缓存任何东西

我在Ubuntu 14.04上有一个LAMP系统

我已经在/etc/php5/apache2/php.ini路径下修改了php.ini我在php.ini 中做了以下更改

opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=120

我放opcache的原因。Enable_cli =1是因为我在PHP中得到以下错误-i

Opcode Caching => Disabled
Optimization => Disabled
Startup Failed => Opcode Caching is disabled for CLI
opcache.enable => On => On
opcache.enable_cli => Off => Off

将opcache。enable_cli=1，我在php中得到以下结果-i

Opcache正在运行，但没有缓存任何东西。在第一次加载页面后，然后我在90秒内刷新页面，我看到一个不同的页面
