Notes

SSL certificates

The host.crt goes first in the bundle

server {
 listen   443;
 ssl    on;
 ssl_certificate    /etc/ssl/your_domain_name.pem; (or bundle.crt)
 ssl_certificate_key    /etc/ssl/your_domain_name.key;
 server_name your.domain.com;
 access_log /var/log/nginx/nginx.vhost.access.log;
 error_log /var/log/nginx/nginx.vhost.error.log;
 location / {
  root   /home/www/public_html/your.domain.com/public/;
  index  index.html;
 }
}

Error messages

no live upstreams while connecting to upstream

can't connect to whatever backend?

upstream sent too big header while reading response header from upstream

• Upstream sent too big header
• Tuning proxy_buffer_size in NGINX

(SSL: error:141CF06C:SSL routines:tls_parse_ctos_key_share:bad key share) while SSL handshaking

Usually just a bad client or a scan.

access forbidden by rule

look for allow or deny lines

a client request body is buffered to a temporary file

PLay some with

client_body_buffer_size 10M;
client_max_body_size 10M;

TODO check, this doesn't seem to apply If all else fails just set:

   proxy_max_temp_file_size 0;

and see if you get some feedback :)

Logging

Log level

Doesn't seem to be documented, defaults to log all?
