Free SSL for web, easy way !

I want say very short steps to make you page secure SSL with “Let’s Encrypt

Free-SSL
Free-SSL

Our case, we consider a server where we have ssh access, and we can modify configuration files from apache and restart services.

First step, install certbot.
yum install certbot

Second, request key for you webpage:
certbot certonly –webroot -w /var/www/html/roundcubemail/ -d webmail.your-domain.com

If you run for the first time here, you will get some questions:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator webroot, Installer None
Enter email address (used for urgent renewal and security notices) (Enter ‘c’ to
cancel): postmaster@your-domain.com
Starting new HTTPS connection (1): acme-v01.api.letsencrypt.org

——————————————————————————-
Please read the Terms of Service at
https://letsencrypt.org/documents/LE-SA-v1.2-November-15-2017.pdf. You must
agree in order to register with the ACME server at
https://acme-v01.api.letsencrypt.org/directory
——————————————————————————-
(A)gree/(C)ancel: A


Next step you will get the key !

IMPORTANT NOTES:
– Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/webmail.your-domain.com/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/webmail.your-domain.com/privkey.pem
Your cert will expire on 2018-10-07. To obtain a new or tweaked
version of this certificate in the future, simply run certbot
again. To non-interactively renew *all* of your certificates, run
“certbot renew”
– Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.
– If you like Certbot, please consider supporting our work by:

Donating to ISRG / Let’s Encrypt: https://letsencrypt.org/donate
Donating to EFF: https://eff.org/donate-le

Final step create you own VHOST config in web server.

webmail
<VirtualHost 192.168.0.1:443>
SSLEngine On
SSLCertificateFile /etc/letsencrypt/live/webmail.your-domain.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/webmail.your-domain.com/privkey.pem
ServerAdmin postmaster@your-domain.com
ServerName webmail.your-domain.com
DocumentRoot /var/www/html/roundcubemail
CustomLog /var/log/httpd/webmailssl_access.log common
ErrorLog /var/log/httpd/webmailssl_error.log
</VirtualHost>

and restart you apache server:  systemctl restart httpd
