How to enable HTTPS in Ubuntu server?

[yourrable]

Hello,

I have Ubuntu VPS running a WordPress blog already. It is using SSL from Let's Encrypt. My calibre-server is running on port 5770. How do I enable HTTPS on my VPS for calibre?

I am running Ubuntu 16 and WordPress site on Apache.

Thank you.

Thank you for the reply.

I am using "Using a URL prefix" as I am not familiar with full virtulhost method and I am afraid of breaking my existing website that is running on my tld with https.

I have added `--url-prefix /calibre` but I can not see anything at `/calibre`. I it still being serverd at `hostnameort/`

What can I do?

I figured it out. I was pointing to the wrong key and certificate file to begin with. I have successfully enabled HTTPS on my calibre server.

Thank you so much.

Hello,

Would it be too much to ask for little step by step turtorial on how to utilize HTTPS in calibre server?
Despite following these instruction https://manual.calibre-ebook.com/server.html I can't figure it out.

I have purchased domain and would like to use its SSL certificate.

Do you have VPS, if yes install certbot. Then generate certificate using certbot. Most of time, it will be done by running simple command, `$ certbot`.

Your certificate and keyfile will be located at `/etc/letsencrypt/live/{your domain name here}/{fullchain.pem & privkey.pem}. Give them necessary read permissions and use it as follow,

/opt/calibre/calibre-server      --enable-auth     --ssl-keyfile /etc/letsencrypt/live/{your domain here}/privkey.pem   --ssl-certfile /etc/letsencrypt/live/{your domain here}/fullchain.pem    --log=/var/log/calibre-server.log     --port=5770    --daemonize "library path"

and you're good to go.

Access your server with `https://ip:port`

Hope it helps.

P.S. Sorry for my bad English.

Why are you running calibre-server from port 80?

Thank you for pointing me in right direction, yourrable.

Strangely I'm experiencing more problems. I simply can't start calibre server. Here's the error

user@xxx:~$ sudo systemctl status calibre.service

My configuration is as follow

[Install]

I'm really puzzled right now.
