opcache设置如下：

; When disabled, you must reset the OPcache manually or restart the
; webserver for changes to the filesystem to take effect.
opcache.validate_timestamps=1

; How often (in seconds) to check file timestamps for changes to the shared
; memory storage allocation. ("1" means validate once per second, but only
; once per request. "0" means always validate)
opcache.revalidate_freq=0

在部署更改时，我发现仍然需要重新启动php-fpm才能看到它们。
我应该调查哪些其他设置？
