I have (and love) nginx front ends that map users to one of many apache
back
ends.
I had php uploads of 2M working. The files were getting posted and all
was
well. I had a request to increase this to 20M and… it doesn’t work.
I see successful posts on the front end (nginx) and back end (apache)
AND
the php upload folder (/tmp/php_uploads) is touched and updated with the
time of the upload. No uploaded temporary file is created. I can change
the
post/buffer size to/from 2M/20M to make it work/not work. It has to be
something obvious (and yes I’ve checked the back end apache/php to make
sure
there are no post/upload limits).
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_redirect off;
proxy_pass http://$server$request_uri;
client_max_body_size 8M;
client_body_buffer_size 8M;
proxy_buffering off;
proxy_connect_timeout 60;
proxy_send_timeout 300;
proxy_read_timeout 120;
proxy_pass_header Expires;
proxy_pass_header Cache-Control;
proxy_pass_header Last-Modified;
proxy_pass_header ETag;
proxy_pass_header Content-Length;
}
As soon as the file tips over 2M, it fails - which is highly suspicious
but
I see no defaults that thwart that. Also, a 7MB upload takes about 30s
so
the send timeout isn’t failing.
What am I missing?
TIA!
