The problem is when i change upload_max_filesizesize then the phpinfowill show the new value, but when I change memory_limitthen nothing changes.
I guess in somewhere the memory_limit is overwrited. But i cannot find it.
Can anyone help me?
问题是当我更改 upload_max_filesize大小时，phpinfo将显示新值，但是当我更改时，memory_limit没有任何变化。我猜在某个地方 memory_limit 被覆盖了。但我找不到它。谁能帮我？

You can take Nginx out of the picture, it just passes the request on, it's in php-fpm running your php code.
你可以把 Nginx 去掉，它只是传递请求，它在 php-fpm 中运行你的 php 代码。
you might check your suhosin settings, suhosin.memory_limit.
你可以检查你的 suhosin 设置，suhosin.memory_limit。
when you see your phpinfo output there should be 2 columns, master and local for memory_limit, what do these each show?
当你看到你的 phpinfo 输出时，应该有 2 列，master 和 local 用于 memory_limit，它们分别显示什么？
128M is the default for memory_limit in php 5.3
128M 是 php 5.3 中 memory_limit 的默认值

In /etc/php5/fpm/php-fpm.confI have php_admin_value[memory_limit] = 512M
在/etc/php5/fpm/php-fpm.conf我有php_admin_value[memory_limit] = 512M
This works for me.
这对我有用。

The problem may be in fpmthe process duplication, even you change your /etc/php5/fpm/php.ini it was not effect.
问题可能出在fpm的进程重复上，即使你改了你的/etc/php5/fpm/php.ini也没有效果。
- Stop php5-fpm with (ubuntu): sudo service php5-fpm stop
- check that no more fpm processes: sudo ps ax | grep fpm
- if any kill it all with: sudo kill -9 pid
- be sure that you kill all fpm processes
- restart: sudo service php5-fpm restart
- 使用 (ubuntu) 停止 php5-fpm： sudo service php5-fpm stop
- 检查没有更多的 fpm 进程：sudo ps ax | grep fpm
- 如果有的话用： sudo kill -9 pid
- 确保您杀死所有 fpm 进程
- 重启：sudo service php5-fpm 重启

Just FYI,
仅供参考，
you should also check in /etc/php5/fpm/pool.dfor any files.
您还应该检查/etc/php5/fpm/pool.d中的任何文件。
It just happened to me that no matter what I wrote on /etc/php5/fpm/php-fpm.conf it would get overrided by /etc/php5/fpm/pool.d/www.conf !
我碰巧无论我在 /etc/php5/fpm/php-fpm.conf 上写了什么，它都会被 /etc/php5/fpm/pool.d/www.conf 覆盖！
So if none of the above answers are not working for you, you should check this (I just lost half hour to this).
因此，如果以上答案都不适合您，您应该检查一下（我刚刚为此浪费了半个小时）。

Also encountered this now and wanted to increase memory of our server in a DigitalOcean droplet
现在也遇到了这个问题，想在 DigitalOcean droplet 中增加我们服务器的内存
To summarize, here is what I did
总而言之，这就是我所做的
sudo nano /etc/php5/fpm/php-fpm.conf
-- press Ctrl-W to do a search in nano text editor
-- if php_admin_value[memory_limit] is there, change it
php_admin_value[memory_limit] = 512M
sudo service php5-fpm restart
You don't need to restart nginx, just restarting phpwould be enough.
您不需要重新启动 nginx，只需重新启动php就足够了。

For me it also ignored php.ini and I had to do the following:
对我来说，它也忽略了 php.ini，我必须执行以下操作：
vim /etc/php-fpm.d/www.conf
php_admin_value[memory_limit] = 10000M ;128M
Then restart php-fpm:
然后重启php-fpm：
service php-fpm restart

Ok this is daft but I had memory_limit set to 2GB, which isn't understood. When I changed that to 2000M it worked!
好吧，这很愚蠢，但我将 memory_limit 设置为 2GB，这是不明白的。当我将其更改为 2000M 时，它起作用了！
