Nginx Uwsgi Configuration¶
If you plan to allow users / staff to download OS images you must configure the uwsgi_max_temp_file_size
directive
accordingly to your needs.
The default value for uwsgi_max_temp_file_size
directive is set to 1GB and you must increase it if you know that you
will have images bigger than this value.
In order to increase that value, you will have to add the directive in /etc/nginx/uwsgi_params
:
Syntax: uwsgi_max_temp_file_size size;
Default: uwsgi_max_temp_file_size 1024m;
The way that download works is that if the whole response does not fit into the buffers set by the uwsgi_buffer_size
and uwsgi_buffers
directives (uwsgi_buffering
is on by default), a part of the response can be saved to a
temporary file. The uwsgi_max_temp_file_size
directive sets the maximum size of that temporary file.
The size of data written to the temporary file at a time is set by the uwsgi_temp_file_write_size
directive.
Syntax: uwsgi_temp_file_write_size size;
Default: uwsgi_temp_file_write_size 8k|16k;
There are more customizations for this (like buffering size, caching, temporary file path, etc.), using the ngx_http_uwsgi_module. You should only modify these if you have an advanced understanding of nginx.
If temporary file saving of response from uwsgi to nginx is enabled make sure you have enough storage space available and that you monitor free storage space.
