Re: [SOLVED] Good nginx ssl instructions

Right. with wget -H http://www.realupnow.com I get that it connects on port 80, responds with redirect (301) to https, and then fails connection on port 443.

That is an indication that the ssl setup is wrong in some way. Perhaps you could show the log again, following your last entry.

Did you confirm that? I accessed your server more recent than that and before I made my post.

I hit Reload - just did it, again.

Wait, I recall noticing that there's an access1.log and an error1.log ...

I'm not sure why there is a second version but I'll check there and post in a minute.

Nothing today and yesterday it just says error log reopened.

The folder/file permissions I posted all look OK?

Re: [SOLVED] Good nginx ssl instructions

Yes all configuration looks fine, although some ssl settings can probably be tuned. But it should connect and allow access. One thing missing is the ssl_dhparam setting which according to doc is required when/if DH ciphers are used. But I would have thought nginx would issue an error message when started/restarted if that would stop it from opening the ssl listener. Try with stopping nginx, then starting it, and check the error log.

Does that host have any local firewall?

Re: [SOLVED] Good nginx ssl instructions

Is there any chance at all that something is insisting on looking at root /var/www/html rather than /var/www?

Or, can you really use about any location e.g. /home/david1/html ?

I need to crash. Eyes getting bleary and starting to sneeze.

I'll check here in the morning for any additional guidance you can offer.

Re: [SOLVED] Good nginx ssl instructions

I meant the host that runs nginx; would be "the Dell-Devuan server" in your house smile

My port probing says that port 80 is open and port 443 is closed; other ports called filtered.

Since you also don't get service on port 443 it means that either nginx does not listen at all, or there is some firewall block in between.

Just for completeness, you should generate the dhparam.pem file:

# openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

and add an ssl_dhparam directive as new line 25 in realupnow.com.conf:

    ssh_dhparam /etc/ssl/certs/dhparam.pem ;

And restart nginx.

After that nginx you could try on that host
# wget -H -O/dev/null http://realupnow.com/
in order to verify that nginx services port 443 (ssl).

EDIT: added semi-colon to the config line.

Re: [SOLVED] Good nginx ssl instructions

This ...

root@devuan1:/etc/nginx/sites-available# lsof -i -P -n | grep LISTEN

... shows that the Dell-Devuan box is listening to 6 different ports on IPv4 (plus a couple of additional ones on IPv6) including 22, 8080, 8001, 8002, 80, 443 - with multiple repetitions.

Re: [SOLVED] Good nginx ssl instructions

From: https://www.techcoil.com/blog/understanding-the-default-nginx-virtual-host-or-server-configuration/

I was wondering if it were possible that this try_files $uri $uri/ =404; was redirecting to here /var/www/html where something in index.nginx-debian.html was messing things up - but that html file just contains a welcome message to nginx.

location / {
    # First attempt to serve request as file, then
    # as directory, then fall back to displaying a 404.
    try_files $uri $uri/ =404;
}

will get Nginx to look for a file inside /var/www/html directory to return as the HTTP response for the incoming HTTP request. In case there is nothing to return, Nginx will return a HTTP response with a 404 status.

But how does the Nginx welcome page gets returned when we try to access the root url? If you trace the configurations from the main file, then you will see the following configuration:
1
	
index index.html index.htm index.nginx-debian.html;

This will cause Nginx to return one of the following files inside the root directory, if available:

    index.html
    index.htm
    index.nginx-debian.html

Since there is a file named as index.nginx-debian.html inside /var/www/html, the contents of the file will be returned when we try to access the root url.
