How to do a large buffer size > 64k uWSGI requests with Nginx proxy
Deployment stack :
Odoo ERP 12
Python 3.7.10 and Werkzeug 0.16.1 as backend
Nginx proxy : 1.20.0
uWSGI : 2.0.19.1
OS : FreeBSD 13.0-RELEASE
Nginx throw an alert from uwsgi of request is too big
Alert : uwsgi request is too big: 81492, client: 10.29.79.250, server:
odoo12ce-erp, request: "GET /web/webclient/..........."
As you can see I increased the "uwsgi_buffer_size " in both uwsgi.ini and
nginx.conf.
Nginx config :
`{
# increase the size of the buffers to handle odoo data
# Activate uwsgi_buffering
uwsgi_buffering on;
uwsgi_buffers 16 128k;
uwsgi_buffer_size 128k;
uwsgi_busy_buffers_size 256k;
# uwsgi_max_temp_file_size with zero value disables buffering of
responses to temporary files
uwsgi_max_temp_file_size 0;
uwsgi_temp_file_write_size 256k;
uwsgi_read_timeout 900s;
uwsgi_connect_timeout 900s;
uwsgi_send_timeout 900s;
}`
uwsgi.ini config :
`
