Question

我不熟悉nginx，无法编辑/修复通过nginx提供的php脚本。我的修复程序不可见 - 似乎脚本文件（或其输出）被缓存，可能是由nginx。配置文件不包含任何fastcgi_cache指令。

我需要更改什么才能编辑php脚本并查看其更新的输出？

php版本是5.4，因此它与opcache无关。它也不是与浏览器相关的，因为不同的浏览器，wget等也是如此。

nginx config：

user root users;
worker_processes  1;

#error_log  logs/error.log;
error_log  /var/log/nginx/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    #access_log  logs/access.log  main;

    sendfile        on;
    #keepalive_timeout  0;
    keepalive_timeout  65;

    gzip  off;
    proxy_buffering off;
    fastcgi_keep_conn on;

    #start server1 section
    server {
    listen       80;
    access_log  /var/log/nginx/access.log;
    location / {

        index  index.php index.html index.htm;
    }

    location /db {

    }

    location /command {

更新

似乎缓存已经在fastcgi服务器中发生了。这是来自nginx错误日志（消息是伪造的，但确实表明php文件不是当前的）：

2015/08/07 12:08:51 [error] 4050#0: *127 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Class 'getID3' not found in /var/www/cover2.php on line 8" while reading response header from upstream, client: 192.168.0.66, server: , request: "GET /cover2.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "192.168.0.35"

Answer 1

织补。终于找到了罪魁祸首：

apc.stat = 0

这可以防止FastCGI PHP服务器中的IO检查。 opcache提示是线索，虽然它的APC，而不是opcache。

Answer 2

它可能是一个浏览器对其经常访问的页面进行缓存，如果是这样，你可以试试这个：

编辑HTML元以告诉浏览器停止缓存：

<meta http-equiv="cache-control" content="max-age=0" />
<meta http-equiv="cache-control" content="no-cache" />
<meta http-equiv="expires" content="0" />
<meta http-equiv="expires" content="Tue, 01 Jan 1980 1:00:00 GMT" />
<meta http-equiv="pragma" content="no-cache" />
