AlmaLinux SSL: Let’s Encrypt Installation

Installing Let’s Encrypt SSL certificates on AlmaLinux involves a few steps. I’ll guide you through the process

Step 1: Install Certbot
Certbot, your trusty companion for SSL certificates, is just a command away. Open your terminal and type:

sudo dnf install certbot

Step 2: Get Your SSL Certificate
Time to grab that SSL goodness! Run Certbot and replace `your_domain.com` with your actual domain:

sudo certbot certonly –standalone -d your_domain.com

Follow the prompts, enter your email, and agree to the terms. Once done, Certbot will hand you your shiny new SSL certificates.

Step 3: Tweak Your Web Server
For Apache users, open your virtual host configuration file:

sudo nano /etc/httpd/conf.d/your_domain.conf

Pop in these lines inside the “ block: apache

ServerName your_domain.com
DocumentRoot /path/to/your/website

SSLEngine on
SSLCertificateFile /etc/letsencrypt/live/your_domain.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/your_domain.com/privkey.pem
SSLCertificateChainFile /etc/letsencrypt/live/your_domain.com/chain.pem

# Other SSL-related configurations

Save and restart Apache:

sudo systemctl restart httpd

Step 4: Set It and Forget It (Almost)
Never worry about SSL renewals. Set up a cron job:

sudo crontab -e

Add this line to check for renewals twice a day:

0 */12 * * * /usr/bin/certbot renew –quiet

Save, and you’re done!

Congratulations! Your AlmaLinux server is now all decked out with a Let’s Encrypt SSL certificate. Remember to replace `your_domain.com` with your actual domain. Happy securing!
