PHP上传文件大小限制的调整 Nginx 413 Request Entity Too Large

Nginx+php-fpm架构，遇到这个错误时：Request Entity Too Large 或 Nginx 413 Request Entity Too Large，须要作以下调整便可。

一、修改配置一：Tune Nignx.conf setting:

# set client body size to 2M under http scope
client_max_body_size 2M;

超时设置：
 

send_timeout    60;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;

二、修改配置二：Tune php.ini settings:

;This sets the maximum amount of memory in bytes that a script is allowed to allocate
memory_limit = 32M

;The maximum size of an uploaded file.
upload_max_filesize = 2M

;Sets max size of post data allowed. This setting also affects file upload. To upload large files, this value must be larger than upload_max_filesize
post_max_size = 3M

 

三、修改配置三：优化php-fpm配置

php_admin_value[memory_limit] = 1224M

3/28 UPDATE：假设上传1M的文件，若是代码中有对文件进行操做的，如写入，移动等，都php-fpm至少要再分配3倍的空间，如3M。若是是上传10M的文件，则要30M php-fpm内存。
