如果这不好，有人会纠正我，但我喜欢尽可能地锁定所有内容，如果您只有一个上传目标(通常情况下)，那么只需将您的更改定向到一个文件。这适用于我的Ubuntu nginx-extras mainline 1.7+包:

location = /upload.php {
    client_max_body_size 102M;
    fastcgi_param PHP_VALUE "upload_max_filesize=102M \n post_max_size=102M";
    (...)
}

请查看是否在http{}块中设置client_max_body_size指令，而不是在location{}块中设置client_max_body_size指令。我已经在http{}块内设置了它，它可以工作

如果您正在使用Kubernetes，请在Ingress中添加以下注释:

annotations:
  nginx.ingress.kubernetes.io/client-max-body-size: "5m"
  nginx.ingress.kubernetes.io/client-body-buffer-size: "8k"
  nginx.ingress.kubernetes.io/proxy-body-size: "5m"
  nginx.ingress.kubernetes.io/proxy-buffer-size: "8k"

确认已应用更改:

kubectl -n <namespace> describe ingress <ingress-name>

客户端缓冲区大小 自定义最大身体尺寸

您需要应用以下更改:

Update php.ini (Find right ini file from phpinfo();) and increase post_max_size and upload_max_filesize to size you want: sed -i "s/post_max_size =.*/post_max_size = 200M/g" /etc/php5/fpm/php.ini sed -i "s/upload_max_filesize =.*/upload_max_filesize = 200M/g" /etc/php5/fpm/php.ini``` Update NginX settings for your website and add client_max_body_size value in your location, http, or server context. location / { client_max_body_size 200m; ... } Restart NginX and PHP-FPM: service nginx restart service php5-fpm restart

注意:有时(在我的情况下几乎每次)，如果php-fpm进程没有通过service命令正确刷新，你需要杀死它。要做到这一点，你可以获得进程列表(ps -elf | grep php-fpm)并逐个杀死(kill -9 12345)或使用以下命令为你做:

ps -elf | grep php-fpm | grep -v grep | awk '{ print $4 }' | xargs kill -9

根据nginx文档，你可以在以下上下文中设置client_max_body_size为20m(或任何你需要的值):

context: http, server, location

下面的配置对我有用。注意，我只设置client_max_body_size 50M;曾经，与别人所说的相反……
