php - Nginx Net::ERR_INCOMPLETE_CHUNKED_ENCODING 试图显示大 JSON

Question

你好，我正在尝试使用 php 显示大型 json，但是当 JSON 文件很大时，我得到 Net::ERR_INCOMPLETE_CHUNKED_ENCODING 并查看

"/var/lib/nginx/fastcgi/1/00/0000000001" failed (13: Permission denied) while reading upstream

在我的 nginx 日志中。

我的 nginx 服务器从 www-data 用户启动。

我的 php-fpm7 也可以在 www-data 上工作

/var/lib/nginx/也归 www-data 所有。

ls -l  nginx
total 20
drwxrwxrwx 2 www-data www-data 4096 Aug 21 21:35 body
drwxrwxrwx 2 www-data www-data 4096 Aug 21 21:35 fastcgi
drwxrwxrwx 2 www-data www-data 4096 Aug 21 21:35 proxy
drwxrwxrwx 2 www-data www-data 4096 Aug 21 21:35 scgi
drwxrwxrwx 2 www-data www-data 4096 Aug 21 21:35 uwsgi

php内存限制为512mnginx body 限制为 100m

服务器运行 usign docker。

我的 nginx.conf

user www-data;
worker_processes auto;

events {
    worker_connections 1024;

    access_log /var/log/nginx/access.log main;
    error_log /var/log/nginx/error.log warn;

    gzip on;
    gzip_disable "MSIE [1-6].(?!.*SV1)";

    gzip_vary on;
    gzip_proxied any;

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

stat 命令的输出

有什么问题吗？

Answer 1

最后通过删除/var/lib/nginx/fastcgi 目录然后从根目录重新创建它并将它的所有者更改为 www-data 来修复。

现在看起来是这样

drwxr-xr-x 2 www-data root     4096 Sep  5 13:58 fastcgi

也可以通过使用这些配置设置调整 fastcgi 缓冲区大小来解决此问题:

    fastcgi_buffers 16 16k;
    fastcgi_buffer_size 32k;
