No love for the awesome ed command? :grinning_face_with_smiling_eyes:
https://www.gnu.org/software/ed/manual/ed_manual.html

Seriously, what's up with the arguments about which editor is better?

@tim_g STFU already. No one fucking cares.

Also get the fuck over yourself already.

Aww, is someone pointing out some flaws / difference of opinion / misconceptions in something you like or prefer?

Here's a guide for you:

I've found a far better thread for discussing the merits of text editors. Enjoy

No. I honestly don't' give a shit about the editors, that was the entire point of why the guide had the comment it had.
But if you want to be a supremacist bitch about your editor of choice, feel free, just take it out of this thread.

Jared where is your nginx.conf

Not supremacist, only correcting misconceptions that were mentioned... as you and Scott do all the time, in any thread they come up. If I do it, then I'm a "supremacist bitch"? Go piss up a rope and slip off.

My experiment last night with Nginx worked. I'm going to see if I can replicate it tonight, and post the config for critique.

I am trying to copy this setup but using wildcard cert instead.
So, i have an http server setup with mediawiki. It has no https.
I have this nginx proxy setup so that the http site is redirected correctly.
edit:well it isnt doing http now either Not sure what i did, was working yesterday just fine.
However it wont seem to proxy https.
I think this is probably because my server.domain.conf in /etc/nginx/conf.d/server.domain.conf proxy_pass parameter is trying to redirect to https of this server which doesnt have https.
What to do in this type of situation?
I asked about this earlier in thread, seems it can work. Ive just messed something up.
I have not messed about with nginx.conf.
Not really sure how it can be used unmodified to proxy https as nothing is defined for https by default.

server.domain.conf file in /etc/nginx/conf.d/ :

server {
        client_max_body_size 40M;
        listen 443 ssl;
        server_name server.domain.com;
        ssl          on;

                proxy_redirect off;
        }
}
server {
        client_max_body_size 40M;
        listen 80;
        server_name server.domain.com;

        location / {

                proxy_pass http://10.1.0.247:80;

On your Mediawiki server, take a look at your LocalSettings.php file. What do you have set for $wgServer?

momurda

It is http://server.domain.com

Why did LE give me .pem files? edit: dont know

Why cant i convert these pem files to .crt and .key? edit: somehow all these .pem files now have 0 size which doesnt make sense. Worked fine yesterday.

openssl x509 -outform der -in cert.pem -out cert.crt

What's the original cert that you have?

You are supposed to have .pem files, always. That tells you the encoding type of the key and certificate. If you did not know pem files mean you have a DER encoded certificate and key file.

If you have a wildcard cert, could you put all the ssl settings into their own ssl.conf file? I won't have time to answer my own question till the middle of next week

EddieJennings

This guide has worked perfectly for me -- great for learning as well, as I had a chance to take pieces and look them up.

Just to make sure my thinking is right, tell me if this is what's happening if I try to reach my site using HTTP.

URL for the example is http://testweb1.ejsllc.com

Request gets to the reverseproxy.
Request does not match the first server block, as it is specifically listening on port 443.
Request does match the second server block since server_name matches and it's listening on port 80.
The second server block rewrites the URL to use https.
The reverse proxy now evaluates the request again, which is now written as https://testweb1.ejsllc.com.
Since no port was specified in the request, reverse proxy assumes the port will be 443, which will match the first server block, which is specifically listening on 443 and matches the server_name.
The reverse proxy unencrypts the request and follows theproxy_pass directive to send it to http://SERVER_IP.
SERVER_IPis listening on port 80, receives the unencrypted request, processes it, and sends the response back to the reverse proxy.
The reverse proxy encrypts the response and send its back to the original requester.

JaredBusch

@eddiejennings Correct.
