我有Debian Stretch跑步nginx+php7为一个WordPress的网站。
这个问题不是关于WordPress的，但关于php7.0-fpm（只是 wordpress 显示我当前的 php 问题）。请不要告诉我“谷歌一下”，我花了半天时间，尝试了所有可能的解决方案。但都不起作用。
在 Wordpress 帖子中，当我上传文件时出现 HTTP 错误（请注意，这不会发生在插件更新和类似操作上）。
我尝试了以下文件类型，但出现错误：
jpg png pdf mp3
以下是我尝试过的文件类型不得到一个错误：
txt doc docx
这是php7.0-fpm.log当我重新启动 php7.0-fpm 并尝试上传三个不同的文件时：

这是 nginx'错误日志：

这是我的有趣部分（我认为）nginx 网站拦截：
location ~ \.php$ {
try_files $uri =404;
include fastcgi_params;
fastcgi_read_timeout 150;
fastcgi_pass unix:/run/php/php7.0-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
这是我的有趣部分（我认为）php7.0 www.conf：
pm = dynamic
pm.max_children = 10
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
问题是：
- 孩子为什么会离开？
- 如果这是由于配置错误，我该如何解决这个问题？
如果您需要有关我的设置的更多信息，请随时询问。
谢谢 ！
