File upload-php uploads large files (more than MB)

I want to know how to upload a file of several hundred MB (no special client software is used ), it seems like you want to partition something. do you know how to do this?

Apache/Nginx on the server supports resumable data transfer and cURL on the client supports resumable data transfer.
By default, the browser supports resumable Upload. you can use jQuery-File-Upload to implement multipart Upload and resumable Upload. the server uses PHP to receive resumable Upload.

To avoid large file upload blocking PHP service, you can open a separate PHP-FPM process pool for upload, using the isolation of the pool provided by the PHP-FPM, separation of computing intensive and I/O intensive (upload) operation to reduce the impact of blocking on the entire PHP application.

Additional instructions:

Nginx and PHP-FPM work process are opened only one.
Upload images in 2KB per second:

Time trickle-s-u 2 curl \-F "action = info. php "\-F" upload_file#@linux.jpeg; type = image/jpeg "\-F" submit = submit "\ http://www.example.com/app/info.phpsudo netstat-antp | egrep" curl | nginx | fpm"

It is found that only nginx and curl are in the ESTABLISHED status, and nginx and fpm are not blocked.

Top-p 4075: Nginx single thread is visible. sudo strace-p 4075: Nginx calls recvfrom to receive data and pwrite saves the data. sudo strace-p 13751 visible the PHP-FPM is acquired only when Nginx receives the data uploaded by the user.

In this case, the FPM process pool I previously imagined is not very useful for processing Upload operations. the PHP-FPM is not blocked during File upload because Nginx receives the uploaded content before being handed over to the PHP-FPM at a time.

Use a third-party breakpoint resume control (activex control)

For example, Xproer. HttpUploader5 is similar to the large attachment of QQ mail.

Or use SWFUpload, which is said to support up to 2 GB

Php configuration file can be changed to a relatively large, but the upload is relatively large do not resumable upload, the actual use of the very uncomfortable, often broken can only be re-transmitted, https://github.com/blueimp/jQuery-File-Upload
