Task 2: Create a Compute Instance and Install the Web Server
Step 1: Create the Compute Instance
Log in to the OCI Console.
Navigate to Compute > Instances.
Click Create Instance.
Enter the following details:
Name: PBT-CERT-VM-01
Compartment: Select your assigned compartment.
Placement: Leave as default or select an availability domain (e.g., Availability Domain 1).
Image: Click Change Image, select Oracle Linux 8, and confirm.
Shape: Click Change Shape, select VM.Standard.A1.Flex, and configure:
OCPUs: 1 (or adjust as needed)
Memory: 6 GB (or adjust as needed)
Networking:
Virtual Cloud Network: Select PBT-CERT-VCN-01.
Subnet: Select Compute-Subnet-PBT-CERT.
Leave public IP assignment enabled for internet access.
SSH Key: Provide your public SSH key (upload or paste) for secure access.
Click Create and wait for the instance to be provisioned.
Step 2: Connect to the Compute Instance
Once the instance is created, note the Public IP Address from the instance details page.
Use an SSH client to connect:
Command: ssh -i opc@
Replace with your private key path and with the instance's public IP.
Step 3: Install and Configure Apache Web Server
Install Apache:
Run: sudo yum -y install httpd
Enable and Start Apache:
Run: sudo systemctl enable httpd
Run: sudo systemctl restart httpd
Configure Firewall to Allow HTTP Traffic (Port 80):
Run: sudo firewall-cmd --permanent --add-port=80/tcp
Run: sudo firewall-cmd --reload
Create an index.html File:
Run: sudo bash -c 'echo 'You are visiting Web Server 1' >> /var/www/html/index.html'
Step 4: Verify the Configuration
Open a web browser and enter http:// to ensure the page displays 'You are visiting Web Server 1'.
If needed, troubleshoot by checking Apache status: sudo systemctl status httpd.
Step 5: Retrieve and Enter the OCID
Go to the instance details page for PBT-CERT-VM-01 under Compute > Instances.
Copy the OCID (a long string starting with ocid1.instance., unique to your tenancy).
Enter the copied OCID exactly as it appears into the text box provided.
Notes
These steps are based on OCI Compute documentation and Oracle Linux 8 setup guides.
Ensure the security list PBT-CERT-CS-SL-01 allows inbound traffic on port 22 (SSH) and port 80 (HTTP) if not already configured.
The OCID will be unique to your instance; obtain it from the OCI Console after creation
