How to Setup WHM & cPanel on AWS Instances

WHM & cPanel is the web-based system management control panel widely used for the Linux hosting environment. To use WHM/cPanel on the AWS environment, we will face the problem with normal instances. So we prefer to use VPC ( Virtual Private Cloud) in aws for installing WHM & cPanel server. This article will help you step by step in brief details for the configuration of the WHM & cPanel hosting environment on AWS instances.

Follow below step by step details for configuring WHM & cPanel on AWS:-

1. Setup VPC (Virtual Private Cloud)

First login to your AWS web console and navigate to below location for creating VPC (Virtual Private Cloud) for your cPanel infrastructure.

• Services >> Networking >> VPC (VPC Dashboard)
• Now click on Start VPC Wizard button.

  

• Select VPC with a Single Public Subnet

  

• Input your CIDR and Public Subnet

  

2. Create EC2 Instance

Now go to EC2 instances section of AWS console and start creating a new instance of your choice using the following steps. Remember that cPanel/WHM supports only CentOS, RedHat and CloudLinux operating systems only.

• Select an Amazon Machine Image (AMI)
• Select an Instance Type
• Configure Instance Details
• Add Storage of your preferred size
• Tag your Instance Name

3. Create Elastic IP

Basically Elastic IP is public IP, which is required to access the instance from public networks. To allocate a new Elastic IP.

• Go to VPC DashBoard
• Select Option Elastic IPs
• Click button Allocate New Address
• Now click “Yes, Allocate” to confirm

4. Bind Elastic IP with Instance

• Go to EC2 Dashboard
• Select Elastic IPs link under “NETWORK and SECURITY” Section in sidebar
• Select your elastic ip and Click “Associate Address”
• Select You newly created instance and click Associate

5. Login to Server and Update

• Login to Server as root user using pem file generated during instance creation.

  ssh -i server.pem root@11.22.33.44
  

• Update all packages on your system using following commands

  yum update
  

• Reboot instance.

  reboot
  

6. Setup Hostname

Use below command to set a hostname temporarily on you rsystem.

# hostname cpanel.example.com

Now make changes permanent by the editing configuration file.

• Edit /etc/sysconfig/network configuration file for RHEL & CentOS

  HOSTNAME=cpanel.example.com
  

• For Ubuntu and Debian systems edit /etc/hostname and enter hostname there

  cpanel.example.com
  

• Now edit /etc/hosts for binding hostname with local system ip.

  10.0.0.100  cpanel.example.com
  

7. Install cPanel & WHM

At this stage, our system is prepared for installing cPanel. Use the following commands to complete the installation. This process will take time as per your network speed and system configuration.

cd /home
yum install wget
wget -N http://httpupdate.cpanel.net/latest
sh latest

8. Setup NAT

Sometimes the system doesn’t automatically detect NAT on your instance. Then you can run below command to do it manually

/scripts/build_cpnat

[output]
info [build_cpnat] 172.32.121.55 => 54.6.169.157

Now to Navigate to Home >> Server Configuration >> Basic cPanel & WHM Setup in your WHM and check for The IPv4 address (only one address) to use to set up shared IPv4 virtual hosts shoud show your public ip address.

9. Open Ports in Security Group

Now open all inbound ports in the AWS security group used by the instance or open specific ports for inbound network listed in the following article.
