Till, in ispconfig I created: SSL Key SSL Request SSL Certificate. After this I opened my website using https://www.example.eu. Firefox gave an error on do you trust this which I accepted and I was able to see my website. What must I do to get an ssl bundle and which provider would you suggest?
The ssl bundle is an optional file. It is not required for self signed ssl certs, thats why the field is empty. You may use any ssl authority to sign the csr generated by ispconfig. Personally I use mostly the certs from comodo.
I put all on the right spot and correct installation was verified by comoco's sslcheck: certificate could be checked and is correct installed. Question: should everyone who now accesses my website see a lock and should it be automatically changed from http to https? How will they see that my site is a secured site?
ahulshof_eu.crt > ssl certificate field. these 3 go into the ssl bundle field. Then select "save certificate" as action and press the save button.

You will see the lock sign when you tpy https:// instead of http://. If you want all your users to use https, then add a http to https redirect in the website.
How to do that? I see: Redirect Type: what to put here? Redirect Path: what to put here? SEO Redirect: what to pot here?
Depends on what you are using. If you are using apache you need something different than when using nginx. Use google mate, "redirect http to https <yourapacheservice>" Or give more info
