Install module:

yum -y install mod_ssl

Disable global set:

cd /etc/httpd/conf.d && mv ssl.conf conf.ssl

Test apache config:

apachectl configtest

See if everything still works:

systemctl restart httpd

Try dry run to obtain the certificate:

certbot certonly --dry-run -a webroot -w /var/www/html -d zbx.catonrug.net

Install for real:

certbot certonly -a webroot -w /var/www/html -d zbx.catonrug.net

This will generate:

/etc/letsencrypt/live/zbx.catonrug.net/privkey.pem

cd /etc/httpd/conf.d && mv zabbix.conf original.conf.zabbix
