To run Ghost on AWS, you can follow these steps:
- Sign in to your AWS console and go to the EC2 service.
- Click on "Launch Instance" to create a new virtual machine.
- Choose an Amazon Machine Image (AMI) that is compatible with Ghost. For example, you can select an AMI running Ubuntu or any other Linux distribution.
- Select the instance type based on your requirements, keeping in mind the recommended specifications for Ghost.
- Configure the instance details, such as the VPC, subnet, security groups, etc., according to your setup preferences.
- Create or select an existing key pair to securely access your instance via SSH.
- Review the instance details and launch the EC2 instance.
- Once the instance is launched, you can connect to it using SSH. Open your terminal or SSH client and connect to the instance using the public IP or DNS provided by AWS.
- Update the package repositories by running the command: sudo apt-get update.
- Install Node.js, which is required to run Ghost, by running:
1 2 |
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash - sudo apt-get install -y nodejs |
- Install the Ghost-CLI, the command-line interface for managing Ghost installations, by running: sudo npm install ghost-cli@latest -g.
- Create a new directory for the Ghost installation by running: sudo mkdir -p /var/www/ghost.
- Change the ownership of the directory to your user by running: sudo chown $USER:$USER /var/www/ghost.
- Navigate to the /var/www/ghost directory: cd /var/www/ghost.
- Install Ghost by running: ghost install.
- Follow the prompts to configure your Ghost installation, e.g., setting up the URL, database configuration, mail setup, etc.
- Once the installation is complete, you can start Ghost by running: ghost start.
- You should now be able to access your Ghost blog by visiting the URL you specified during the configuration.
These steps should guide you through setting up and running Ghost on AWS. Ensure that you have a solid understanding of AWS services and permissions required to create and manage instances, as well as familiarity with the command line interface to execute the necessary commands.

What is DNS?
DNS stands for Domain Name System. It is a decentralized system that translates domain names (such as www.example.com) into IP addresses (such as 192.168.0.1) to locate and connect to the appropriate server on the internet. DNS acts as a phonebook of the internet, allowing users to access websites and other resources using easy-to-remember domain names instead of complicated numerical IP addresses. It also helps in managing email delivery, ensuring reliable communication across the internet.
How to generate an AWS key pair for accessing an EC2 instance?
To generate an AWS key pair for accessing an EC2 instance, you can follow these steps:
- Login to the AWS Management Console.
- Navigate to the EC2 service.
- Click on "Key Pairs" in the left-hand sidebar under "NETWORK & SECURITY".
- Click on the "Create Key Pair" button.
- Provide a name for your key pair (e.g., "my-key-pair").
- Select the file format for your key pair (either ".pem" or ".ppk" depending on your client).
- Click on the "Create Key Pair" button to initiate the key pair generation process.
- The private key file will be automatically downloaded to your local machine. Store this key in a secure location.
- Once the key pair is created and stored securely, you can associate it with your EC2 instances during the creation process or by modifying the instance attributes.
It's important to note that once the private key is downloaded, it should be kept safely as you won't be able to download it again. Also, treat your private key as confidential information and never share it with others.
How to point a domain to an EC2 instance's IP address?
To point a domain to an EC2 instance's IP address, you need to perform the following steps:
- Obtain the Public IP address of your EC2 instance. You can find this information in the EC2 management console by selecting your instance and checking the "IPv4 Public IP" value.
- Log in to your domain registrar or DNS provider and access your domain management settings.
- Look for an option to edit DNS records, typically called something like "DNS Management" or "Manage DNS".
- Create a new DNS record or update an existing one. This will depend on the specific interface of your domain registrar or DNS provider, but the record you need to create or update is an "A Record" (Address Record). A Record maps a domain name to an IPv4 address.
- In the A Record configuration, enter your domain name (e.g., example.com) and specify the EC2 instance's Public IP address as the target. Save the changes.
- Wait for the DNS changes to propagate. This process may take some time, but typically it is effective within a few minutes to a few hours.
- Verify that the domain is properly pointing to your EC2 instance by accessing your domain in a web browser. It should now load the content hosted on your EC2 instance.
Note: You may also want to consider configuring a domain using a more user-friendly approach, such as using an Elastic IP address or an Elastic Load Balancer with an associated domain name instead of relying on the instance's Public IP address directly.
What is a database?
A database is an organized collection of data stored and accessed electronically. It is designed to efficiently store, manage, and retrieve information. A database typically consists of one or more tables, each containing fields (attributes) to hold different types of data. These tables are related to each other through key relationships, allowing for the efficient retrieval and querying of information. Databases are widely used in various applications such as websites, business operations, scientific research, and more.
What is AWS?
AWS stands for Amazon Web Services. It is a comprehensive cloud computing platform offered by Amazon.com that provides a wide range of cloud services, including compute power, storage, database, analytics, networking, machine learning, and more. AWS enables businesses and individuals to access and use these services on a pay-as-you-go basis, without the need to invest in expensive hardware and infrastructure. It is a dominant player in the cloud computing industry and offers scalability, flexibility, and reliability to its customers.
