Make your website secure with Let’s Encrypt (Certbot) free SSL. post thumbnail image

It is important to use SSL to make your website encrypted. In this method, I will show you how to install SSL in Ubuntu 16.04. 






  1. First, you need to install certbot tool by the below command










root@Linoide:~# apt update root@Linoide:~# apt install letsencrypt















2. Now Generate wildcard SSL using certbot tool.







root@Linoide:~# certbot certonly --manual --preferred-challenges=dns --email admin@linoide.com --server https://acme-v02.api.letsencrypt.org/directory --agree-tos -d linoide.com -d '*.linoide.com'







Note: ’email’ , ‘-d (domain name)’ with your own email and domain name. 





You need to type ‘Y’ two times while deploying this command and then finally the out looks like this





Please deploy a DNS TXT record under the name
_acme-challenge.linoide.com with the following value:
h#cUndYwcxrKkR%GD6RD^2GFz&2$j#QgR5NgG
Before continuing, verify the record is deployed. 

3. Now, create a TXT name in Godaddy(or your domain provider) as below. After record added, wait for few minutes and then click ENTER to continue  deploy in your server. 










Note: Domain provider will take several minutes of time to update your record. 





Example Output:





IMPORTANT NOTES:
Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/linoide.com/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/linoide.com/privkey.pem
Your cert will expire on 2022-10-17. 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:

4. You can check your all certbot certificates by using this command





# certbot certificates





Example Output





root@Linoide:~# certbot certificates
Saving debug log to /var/log/letsencrypt/letsencrypt.log

Found the following certs:
Certificate Name: linoide.com
Domains: linoide.com *.linoide.com
Expiry Date: 2021-01-15 14:11:10+00:00 (VALID: 89 days)
Certificate Path: /etc/letsencrypt/live/linoide.com/fullchain.pem
Private Key Path: /etc/letsencrypt/live/linoide.com/privkey.pem
















Congratulations! You have installed free SSL certificate on your server. 





But Wait……





Its for only 90 days. What about after that? Do you need to create another certificates or follow all these process again and again?





NO..





Just create a cronjob to renew certbot certificates automatically. 















5. Run this command to edit cronjob





root@Linoide:~# crontab -e










and now add below line to your cronjobs and save the file





0 1 * * * /usr/bin/certbot renew >> /var/log/letsencrypt/renew.log










That’s it!










SSL Certs are created now you need to enable them into your webpage. Let’s enable SSL
