Install the httpd package
The following command installs the httpd package and all of its dependencies.

sudo yum install httpd -y

Enable and start the httpd service
To enable and start the httpd service for immediate access and make the service start automatically after a reboot, run the following command:

sudo apachectl start
sudo systemctl enable httpd

The service starts a web server that listens on TCP port 80 by default.
To check the status of the service, run this command:

sudo service httpd status

Configure firewall rules (Optional):
If you are using a custom firewall profile or an Oracle Cloud Infrastructure instance, open the firewall port for the Apache web service (80).
These commands enable the firewall port for the Apache web service and reload the default firewall service:

sudo firewall-cmd --permanent --zone=public --add-port=80/tcp
sudo firewall-cmd --reload

Test your deployment
With your web browser, go to the domain name or IP address of your system.

http://myserver.example.com/ 
or IP address
http://130.61.....

The Apache web server opens the default test page.
