Turns out I'm trying to mount a https web server and when I try it I get an error, the code is as follows:

with this code generate the certificate:

require 'webrick'
require 'webrick/https'

cert_name = [
%w[CN localhost],
]

server = WEBrick::HTTPServer.new(:Port => 8000,
:SSLEnable => true,
:SSLCertName => cert_name)

After generating it, edit the file and put this:

require 'webrick'
require 'webrick/https'
require 'openssl'

cert = OpenSSL::X509::Certificate.new File.read '/path/to/cert.pem'
pkey = OpenSSL::PKey::RSA.new File.read '/path/to/pkey.pem'

server = WEBrick::HTTPServer.new(:Port => 8000,
:SSLEnable => true,
:SSLCertificate => cert,
:SSLPrivateKey => pkey)

and I get this error:

./Servidorweb.rb:11:in 'read': No such file or directory @ rb_sysopen - /path/to/cert.pem (Errno::ENOENT)
from ./Servidorweb.rb:11:in '<main>'

Does anyone know what can be done? probe with port 9000 and also gives me error

The error you get is because the file cert.pem is not found in the specified path (i.e. /path/to/ ). Probably the route you currently have in your code (i.e. /path/to/cert.pem ) is just an example, where you should replace /path/to with the actual location of the file cert.pem .

For example, if your file were a subdirectory certificados , which in turn is inside the directory pruebas which is in the root (ie root> tests> certificates ), the path would be /pruebas/certificados/cert.pem .

To solve the problem, change the path to the one where the files cert.pem and pkey.pem are found.

Considering the path of the previous example ( /pruebas/certificados ), your code would look like this:

cert = OpenSSL::X509::Certificate.new File.read '/pruebas/certificados/cert.pem'
pkey = OpenSSL::PKey::RSA.new File.read '/pruebas/certificados/pkey.pem'

On relative and absolute paths

Consider that when you use / at the start you are using an absolute path, so you must have your file on that route.

If you want to use a relative path, then remove the first / ; although he considers that in this way you should always run the program from the same directory.

For example, your relative route would look like this:

File.read 'path/to/cert.pem'

Then if you run your program from /home/app :

home/app $ ruby Servidorweb.rb

This would search the file in

home/app/path/to/cert.pem

Considering the above, I always recommend using absolute routes, just as you have it in your program; just verify that this route is the correct one (in your case it is not, that's why it shows the error).
