2. Get a SSL/TSL certificate with letsencrypt:

To create a new SSL certificate for the domain example.com and www.example.com, type the below code in terminal and hit enter.

Note: Replace example.com and www.example.com with your domain.
Example: Here i am using uvari.info for this tutorial.

letsencrypt certonly --manual --email admin@example.com -d example.com -d www.example.com

Example for my domain

letsencrypt certonly --manual --email admin@uvari.info -d uvari.info -d www.uvari.info

It will ask you to agree some license agreements. Type A and Hit Enter for OK.

It will also ask for IP logging. Type Y and hit enter key to confirm it.

Then it will give you a challenge to verify your ownership of the domains. Like below.

Example:

Make sure your web server displays the following content at http://uvari.info/.well-known/acme-challenge/hRiVw4n5HkMKjGOJ5sM1LH6aZ7PAikvQ50P5v5ol3HYHHH before continuing:

hRiVw4n5HkMKjGOJ5sM1LH6aZ7PAikvQ50P5v5ol3HYHHH.vBE2BdGTIzmo319dQAzEVl1HjPuYrr80O49aLOblk7M

To solve the challenge, go to your domian root that is your public_html folder and create .well-known folder. Inside that .well-known folder create acme-challenge folder and then inside the acme-challenge folder create hRiVw4n5HkMKjGOJ5sM1LH6aZ7PAikvQ50P5v5ol3HYHHH folder.

Here this folder name is different for each user. Note yours and create according to yours. And inside that create a index.html file. Open that file and copy /paste the second content. That is  hRiVw4n5HkMKjGOJ5sM1LH6aZ7PAikvQ50P5v5ol3HYHHH.vBE2BdGTIzmo319dQAzEVl1HjPuYrr80O49aLOblk7M for my case without any space. This content is also varies. Replace it with yours.

You will have to complete this challenge twice for each of the domains provided.

After you complete these two challenges you should get a success message like below screenshot.


3.Install letsencrypt certificate on your domain.

After generating the certificate you need to install it on your domain. Here i am using cpanel control panel to manage my hosting. This procedure is not very different for other control panels.

The certificate is saved in /etc/letencrypt/live/example.com directory. Replace example.com with your domain name. You can see several files, but we need just the below 3 files.

privkey.pem
cert.pem
chain.pem

Here privkey.pem is the private key, cert.pem is the ssl certificate and chain.pem is Certificate Authority Bundle (CABUNDLE).

In your terminal run the below code. it will open nautilus file browser as root.

gksudo nautilus

Now login to cpanel and look down for SSL/TSL manager. And open it.

Click Generate, view, upload, or delete your private keys link. Now go back to the opened nautilus file browser as root and open the privkey.pem file with any text editor or gedit. Then copy all the contents from that file and paste it on “Paste the key below:” section and click the save button.

Now go to to ssl/tsl manager and click Generate, view, upload, or delete SSL certificates link.And open the cert.pem file with any text editor or gedit as root. Then copy all the contents from that file and paste it on “Paste your certificate below:” section and click the save certificate button.

Now again  go to ssl/tsl manager and click Install and Manage SSL for your site (HTTPS) link. Select your domain from dropdown and Copy the cert.pem content to Certificate: (CRT) box, privkey.pem content to  Private Key: (KEY) box and chain.pem content to Certificate Authority Bundle: (CABUNDLE) text box. And click the Install Certificate button.

Thats it. Now go to https://example.com in your browser. Replace example.com with your domain.
