nginx+php uploading a file failed client_max_body_size

Nginx upload parameter problem, need to pay special attention to client_max_body_size this parameter, otherwise it will interrupt the request in Nginx.

General PHP configuration for file upload parameters php.ini file is as follows:

The default is 2mpost_max_size 8m refers to the maximum value that can be received by the form Post to PHP, including all values in the form. Default is 8M

Generally, set up the above four parameters, in the network normal situation, upload <=8m files is not a problem
However, if you want to upload a large volume of >8m files, only set the above four items will certainly be able to pass. Unless your network really has a 100m/s upload speed, you still have to set the following parameters.

Max_execution_time 600 Maximum time value per php page (seconds), default 30 seconds Max_input_time 600 the maximum time per PHP page to receive data, default 60 seconds Memory_limit 8m Maximum memory consumed per PHP page, default 8M

Client_max_body_size 30m;

Restart can

30m indicates the maximum upload 30M, how much to set the size of
