How to install lets encrypt SSL in amazon Linux AMI.i want to implement the lets encrypt SSL for my domain.

Answer 1

There are a lot of solutions online; I think you have to keep on trying until you find one that works for you. After a lot of experimentation, what worked for me was following the certbot instructions for Apache and CentOS 6. The official link is here, but for consistency:
Run the following commands in the terminal:
Download Certbot
wget https://dl.eff.org/certbot-auto
sudo mv certbot-auto /usr/local/bin/certbot-auto
sudo chown root /usr/local/bin/certbot-auto
sudo chmod 0755 /usr/local/bin/certbot-auto
Execute Certbot
sudo /usr/local/bin/certbot-auto --apache
If there's an error message, read the warning and run (if you feel comfortable):
sudo /usr/local/bin/certbot-auto --apache --debug
Here, you may be asked to complete some fairly intuitive questions to configure your installation. If not, what worked for me won't work for you. :(
Automate Renewal
Test to see if renewing your certificate works:
sudo /usr/local/bin/certbot-auto renew --dry-run
If so, navigate to your system's crontab (usually somewhere around /etc/crontab/) and add the following code to check (and run, if necessary) and auto-renewal at midnight and noon everyday:
0 0,12 * * * python -c 'import random; import time; time.sleep(random.random() * 3600)' && /usr/local/bin/certbot-auto renew

Here I will explain how to configure let's encrypt in Linux AMI. I did it successfully in my Linux AMI.i followed the following steps to get it done.
1. SSH into your server.
2. Download certbot (the Let’s Encrypt client need to install for renew and install ssl): **wget https://dl.eff.org/certbot-auto** then **chmod a+x certbot-auto**
3. Run certbot to fetch your certificates.follow the below code
sudo ./certbot-auto --debug -v --server https://acme-v01.api.letsencrypt.org/directory certonly -d YOUR_DOMAIN [Replace your Domain in YOUR_DOMAIN placeholde]
4. while generating it will ask you the recover or support email please add your email.
5. certbot will place your certs in the following paths…
Certificate: /etc/letsencrypt/live/YOUR_DOMAIN/cert.pem
Full Chain: /etc/letsencrypt/live/YOUR_DOMAIN/fullchain.pem
Private Key: /etc/letsencrypt/live/YOUR_DOMAIN/privkey.pem
6. Go to your apache config where you created a virtual host it can be either in httpd.conf or conf.d.
7. Add the virtual host for 443 port
<VirtualHost *:443>
ServerAdmin ADMIN_EMAIL
ServerName YOUR_DOMAIN
ServerAlias www.YOUR_DOMAIN
DocumentRoot "YOUR FOLDER PATH"
AllowEncodedSlashes On
ErrorLog "/var/log/httpd/YOUR_DOMAIN_error.log"
CustomLog "/var/log/httpd/YOUR_DOMAIN-sslaccess.log" common
<Directory YOUR FOLDER PATH>
DirectoryIndex index.php
Options -Indexes
AllowOverride All
</Directory>
SSLEngine on
SSLCertificateFile /etc/letsencrypt/live/YOUR_DOMAIN/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/YOUR_DOMAIN/privkey.pem
SSLCertificateChainFile /etc/letsencrypt/live/YOUR_DOMAIN/fullchain.pem
</VirtualHost>

Answer 3

You need to install Certbot if you are running CentOS 7 or 8 since Certbot-auto is deprecated and doesn't work beyond CentOS 6.
You can check which CentOS you are running by using the following command.
rpm -E %{rhel}
And use this tutorial from amazon to install Certbot in Amazon Linux
sudo yum update
sudo yum install -y certbot python2-certbot-apache
If you get "Package not found" error, then try the Prepare to Install section from the same blog.
sudo wget -r --no-parent -A 'epel-release-*.rpm' https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/
sudo rpm -Uvh dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-*.rpm
sudo yum-config-manager --enable epel*
