Connection to $IPADDRESS closed.

Please wait at least 2 minutes before logging in again.

SSH Access & Initial Setup

• Log in as ubuntu using your credentials or SSH key
• Switch to root:

sudo su -

On first login, the script will display passwords and prompt you to enter a domain:

Enter the domain name for your new Joomla site:
(ex. example.org or test.example.org)

The domain’s A record must point to the instance’s IP address.

Joomla Setup via Web Interface

After setup:

• Access Joomla via browser:

http://$IPADDRESS

Or use the configured domain.

• Complete Joomla installation through the web installer.

Stored Credentials & Paths

• MySQL root password: /root/.mysql_root_password
• Joomla DB info: /root/.joomla_database_details
• phpMyAdmin credentials:
  • User: admin
  • Password: /root/.phpmyadmin_password
• phpMyAdmin URL: http://$IPADDRESS/phpmyadmin
• Web root: /var/www/html
• Joomla config file: /var/www/html/configuration.php
• phpMyAdmin config directory: /etc/phpmyadmin/

Apache Virtual Host Configuration

To host multiple Joomla sites:

1. Create a directory for your domain:

mkdir -p /var/www/yourdomain.com/html

2. Create a virtual host config file:

nano /etc/apache2/sites-available/yourdomain.com.conf

3. Add the config:

<VirtualHost *:80>
    ServerAdmin webmaster@yourdomain.com
    ServerName yourdomain.com
    ServerAlias www.yourdomain.com
    DocumentRoot /var/www/yourdomain.com/html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

4. Enable site and reload Apache:

a2ensite yourdomain.com.conf
systemctl reload apache2

SSL Setup with Certbot

Ensure DNS A and www records point to your instance. Then run:

certbot --apache -d example.com -d www.example.com

Allow port 443 in the firewall. Optionally block port 80 after successful SSL setup.

Postfix Configuration

1. Set a valid hostname:

hostnamectl set-hostname your.hostname.com

2. Ensure DNS A and PTR records are in place.
3. Update Postfix config:

nano /etc/postfix/main.cf

Set:

myhostname = your.hostname.com

4. Restart Postfix:

systemctl restart postfix

5. Test mail delivery:

echo "Postfix test" | mail -s "Subject" test@gmail.com

Emails may land in spam initially until IP reputation improves.

Best Practices

• Change default passwords immediately
• Secure Apache with headers and mod_security if needed
• Enable automatic updates for Joomla and plugins
• Regularly back up the database and configuration files
