How to Install and Configure Apache on AlmaLinux 9

To install and configure Apache on AlmaLinux 9, follow these steps:

Step 1 : Before installing any packages, make sure your system is up to date:

sudo dnf update -y

Step 2 : Install the Apache web server by running the following command:

sudo dnf install httpd -y

Step 3 : If you have a firewall enabled, you need to allow HTTP and HTTPS traffic. Run these commands to allow access:

sudo firewall-cmd --add-service=http --permanent
sudo firewall-cmd --add-service=https --permanent

After adjusting the firewall rules, reload it to apply the changes:

sudo firewall-cmd --reload

Step 4 : Start the Apache service and enable it to start on boot:

sudo systemctl start httpd
sudo systemctl enable httpd

Step 5 : Verify that Apache is running properly by checking its status:

sudo systemctl status httpd

Step 6 : Create a directory for your domain and an index.html file:

sudo mkdir -p /var/www/example.com/public_html
echo "<html><body><h1>Welcome to example.com</h1></body></html>" | sudo tee /var/www/example.com/public_html/index.html

Step 7 : Create a virtual host configuration file for example.com:

sudo nano /etc/httpd/conf.d/example.com.conf

Add the following content:

<VirtualHost *:80>
    ServerName example.com
    DocumentRoot /var/www/example.com/public_html
    ErrorLog /var/log/httpd/example.com_error.log
    CustomLog /var/log/httpd/example.com_access.log combined
</VirtualHost>

Step 8 : Test the Apache configuration for syntax errors:

sudo apachectl configtest

You should see Syntax OK if everything is correct.

Step 9 : Restart Apache to apply the changes:

sudo systemctl restart httpd

Step 10 : Open your web browser and visit http://example.com. You should see the "Welcome to example.com" message.

Congratulations, you have successfully installed and configured Apache on AlmaLinux 9!
