Description
I am using NGINX on Windows as a reverse proxy to a library endpoint. I want to increase the value in the proxy_max_temp_file_size directive to serve some of my larger libraries.
However, setting proxy_max_temp_file_size to a value above 1024m gives me the following error:
`
nginx: [emerg] "proxy_max_temp_file_size" directive invalid value in path/to/nginx.conf:178
`
Here is the full nginx.conf
`nginx
#user nobody;
worker_processes 2;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
# upstream endpoint
upstream pypi-gpu {
server localhost:9500;
}
server {
listen 9000 ssl;
server_name pythonlibs.mydomain.com;
ssl_certificate "path/to/cert.crt";
ssl_certificate_key "path/to/private.key";
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers HIGH:!aNULL:!MD5;
location / {
proxy_max_temp_file_size 3072m;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://pypi-gpu;
}
}
}
`
Note that setting proxy_max_temp_file_size 0 allows me to serve large files but I'd prefer to keep this bounded if possible.
nginx version: nginx/1.27.0
On win32 max value of size_t allowed by nginx is 2G, which is 2048M. Everything greater than that will be rejected. This can potentially be fixed in the future by switching to off_t instead.
