在服务器上将大文件上传到Amazon S3失败

Question

I am experiencing an issue when try to upload file of 4MB to S3 bucket using PHP SDK. This is working fine in my vagrant environment. But when I try on EC2 production server, it gives below error when I am going to upload even 2MB size of file. But small size of files can be uploaded without problem. Can someone please help me on this?

I am using nginx for both environments.

    $s3 = \App::make('aws')->createClient('s3');
    $name= time() . $file->getClientOriginalName();
    $resp = $s3->putObject(array(
        'Bucket' => 'xxxxxx',
        'Key' => $folder.'/' . $name,
        'ACL' => 'public-read',
        'Body' => new Stream(fopen(realpath($file->getPathName()), 'r'))
    ));

    if ($resp['@metadata']['statusCode'] == 200) {
        return [
            "file_path"=>$resp['ObjectURL'],
            "s3_key"=>$folder.'/' . $name
        ];
    }else{
        return false;
    }

Error executing "PutObject" on " https://xxxxxxx.amazonaws.com/documents/1564900266slides.zip "; AWS HTTP error: Client error: PUT https://xxxxxxx.amazonaws.com/documents/1564900266slides.zip resulted in a 400 Bad Request response: RequestTimeoutYour socket connection to the server wa (truncated...)

Check that nginx has a parameter set like client_max_body_size 20M; to allow file upload up to 20 MB. As for PHP, you could check in php.ini upload_max_filesize = 20M to match nginx configuration.

Once you have set those parameter you'd have to check nginx configuration with sudo nginx -t and reload configuration with sudo service nginx reload to apply the new settings.
