How to install valid SSL certificate on zPanel hostname (not IP)

[Fli]

This worked on my CentOS 6.x zPanel VPS. I repalced self signed SSL by LetsEncrypt.org SSL when accessing cpanel via server hostname. IP still via self signed)
------------

I made sure my hostname is valid FQDN (containing two dots in hostname)

executed command to set my hostname: hostname host1.mydomain.com

Then i verified my hostname is in /etc/hosts filenext to my server IP:
MyServerIPHere vps host1 host1.mydomain.com myonionaddress.onion

then with my server provider i asked them to set my PTR (rDNS) record of my IP to host1.mydomain.com

then i went to https://certbot.eff.org/ and after installing certbot using given instructions i executed command to generate cert. for my hostname:

./certbot-auto certonly -d host1.mydomain.com

Then i had certificate config file in: /etc/letsencrypt/renewal/host1.mydomain.com.conf

i listed that file contents to discover location of my certificate and private key: cat /etc/letsencrypt/renewal/host1.mydomain.com.conf

i copied lines that begins with cert and privkey

I opened default apache SSL configuration file:
vi /etc/httpd/conf.d/ssl.conf

Then hit slash: /
and typed: Cert
and hit enter

Then i commented out default line to look like:
#SSLCertificateFile /etc/pki/tls/certs/localhost.crt

and below added line:
SSLCertificateFile /etc/letsencrypt/live/host1.mydomain.com/cert.pem

Then below is keyfile line that i also commented out to look like:
#SSLCertificateKeyFile /etc/pki/tls/private/localhost.key

and below i added:
SSLCertificateKeyFile /etc/letsencrypt/live/host1.mydomain.com/privkey.pem

then exitted editor by :wq and hit enter

and restarted httpd: service httpd restart

i could enter https://host1.mydomain.com and it shown valid LetsEncrypt.org SSL zPanel login screen

setup cronjob to renews SSL automatically:

crontab -e

add to the end of file:
@daily /bin/sh /certbot-auto renew
