Recommended Posts

Hello,
I try to set ssl for my php/laravel application under Digital Ocean with Kubuntu 18
as in this articles
https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-18-04

But I got error trying to use certbot to obtain a free SSL certificate :
# sudo ufw status

"www.products-catalog.nilov- sergey -demo-apps. tk " does not resolve to an IP address.

You need either an "A" or a "CNAME" record for "www.products-catalog.nilov-sergey-demo-apps.tk"

An "A" record will point to the IP address.

But if "www.products-catalog.nilov- sergey -demo-apps. tk" has the same IP as "products-catalog.nilov- sergey -demo-apps. tk", then you can use a "CNAME" record pointing to "products-catalog.nilov- sergey -demo-apps. tk"

I made some more review and found next :
IP of my server is 138.68.107.4 and under ssh I enter the console of OS as 

ssh root@138.68.107.4

But in my /etc/hosts file I had next lines pointing to some other hosts on this server:

# 127.0.0.1 localhost
127.0.0.1 localhost.localdomain localhost
138.68.107.4  box.example.com box


# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

138.68.107.4  votes.nilov-sergey-demo-apps.tk
138.68.107.5  products-catalog.nilov-sergey-demo-apps.tk
138.68.107.6  csvp.nilov-sergey-demo-apps.tk

...

I modified 3 last lines as :

138.68.107.4  votes.nilov-sergey-demo-apps.tk
138.68.107.4  products-catalog.nilov-sergey-demo-apps.tk
138.68.107.4  csvp.nilov-sergey-demo-apps.tk

But I still not sure is that is valid value, as I have next error again:

# sudo certbot --apache -d products-catalog.nilov-sergey-demo-apps.tk -d www.products-catalog.nilov-sergey-demo-apps.tk

 can reason of this error be in wrong IP in /etc/hosts or some other issue ?
