遇到这个问题.. nginx 似乎会保留不再在磁盘上的文件，这不是浏览器缓存问题，因为我可以用 curl 进行测试。

例如.. curlhttps://staging.xxxx.co/ <!DOCTYPE html><ht ... src="/app/main.92974ab5ce4e059cd6a0.js .. 该文件不再存在于磁盘上..

重新启动可以解决问题 - 例如 curlhttps://staging.xxxx.co/ <!DOCTYPE html><ht ... src="/app/main.5920b750cb8af60be300.js ..

有什么建议吗？我已经检查过了Nginx 似乎正在发送页面的缓存版本

Linux 服务器是 ubuntu 16.04 - 最新版、nginx/1.10.3 (Ubuntu)、php 7.2

我通过在 /etc/php/7.2/fpm/php.ini 中禁用 opcache 解决了这个问题：

opcache.enable=0

更新：

正如 RobIII 在评论中正确指出的那样，opcache.enable=0这将禁用 opcache，而您应该在生产服务器上启用它。对于生产，您应该使用 systemctl 或服务命令重新加载 php-fpm：

systemctl reload php-fpm

或者使用应用程序目录中的 php 脚本（/var/www/html默认情况下或在 OP 的情况下/var/www/staging.xxxx/current/public），然后您可以在需要时从浏览器调用它：

<?php 
opcache_reset();

或者，更优雅的是，使用命令行中的自定义 bash 命令（借用自php.net 评论)：

#!/bin/bash
WEBDIR=/var/www/html/
RANDOM_NAME=$(head /dev/urandom | tr -dc A-Za-z0-9 | head -c 13)
echo "<?php opcache_reset(); ?>" > ${WEBDIR}${RANDOM_NAME}.php
curl http://localhost/${RANDOM_NAME}.php
rm ${WEBDIR}${RANDOM_NAME}.php

将其放入 /usr/local/bin/opcache-clear 并使其可执行。当我想清除缓存时，我只需在终端内运行“opcache-clear”。
