Ghost, a popular open-source content management system (CMS), can be deployed on various platforms and environments. Here are a few options for deploying Ghost:
- Self-hosting: Ghost can be self-hosted on your own server or virtual machine. This option gives you complete control over the hosting environment and allows for customization based on your specific needs.
- Ghost(Pro): Ghost offers its own hosting solution called Ghost(Pro). This managed hosting service is specifically built for Ghost and ensures hassle-free deployment, automatic backups, continuous updates, and excellent performance.
- Cloud platforms: Ghost can be deployed on popular cloud computing platforms such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform. These platforms provide scalable infrastructure and easy management options for deploying Ghost.
- Docker containers: Ghost provides official Docker images that allow you to deploy and run Ghost in a containerized environment. Docker simplifies the deployment process and ensures consistency across different hosting environments.
- One-click installers: Some hosting providers offer one-click installers for Ghost, meaning you can quickly deploy Ghost with just a few clicks without any technical setup or manual configuration.
It is important to consider factors like your technical expertise, scalability requirements, budget, and desired level of control when choosing a deployment option for Ghost.

How to deploy Ghost in a high-availability configuration?
To deploy Ghost in a high-availability configuration, follow these steps:
- Set up an infrastructure: You will need at least two servers with load balancers to distribute traffic across multiple instances of Ghost. You can use cloud-based platforms like AWS, Google Cloud Platform, or Azure for this purpose.
- Install Ghost: Install Ghost on each server following the official instructions provided by the Ghost team. Make sure to configure each instance with the same settings, including database details and Ghost URL.
- Set up a database: Ghost requires a database to store content and other meta information. You can either use a shared database like MySQL or PostgreSQL, or set up a replicated database like Amazon RDS Aurora or Google Cloud SQL. Ensure that all Ghost instances have access to the database.
- Configure a load balancer: Set up a load balancer that directs traffic to the Ghost instances. This can be achieved using a load balancer provided by your cloud platform, such as AWS Elastic Load Balancer or Google Cloud Load Balancer. Configure the load balancer to evenly distribute traffic between all Ghost instances.
- Share content images: Ghost stores images and other content on the local file system. To ensure images are available across all instances, configure a shared storage solution like S3, Azure Blob Storage, or a distributed file system such as NFS or GlusterFS.
- Enable session affinity: By default, Ghost stores sessions in-memory, which can cause issues with multiple instances. Configure Ghost to use a shared session store like Redis or Memcached to ensure session affinity across multiple instances.
- Configure SSL termination: Set up HTTPS termination on the load balancer to ensure secure connections to your Ghost instances. You can use SSL/TLS certificates from a certificate authority or provision them directly from your cloud provider.
- Test the configuration: Test the high-availability configuration by accessing the Ghost site through the load balancer's URL. Make sure requests are distributed correctly and content is being rendered properly.
- Monitor and scale: Set up monitoring tools to track the performance of your Ghost instances and load balancer. Monitor key metrics like CPU usage, response time, and error rates. If necessary, add more instances or increase the capacity of existing instances to handle higher traffic loads.
By following these steps, you can deploy Ghost in a high-availability configuration, ensuring that your site remains highly available even in the event of server failures or high traffic loads.
What is the best architecture for deploying Ghost in a scalable manner?
The best architecture for deploying Ghost in a scalable manner depends on various factors such as expected traffic, budget, and specific requirements. However, here is a commonly recommended architecture:
- Reverse Proxy: At the front, use a reverse proxy like Nginx or Apache to handle SSL termination, load balancing, and caching. This enables distributing incoming requests to multiple backend Ghost servers.
- Load Balancer: Implement a load balancer, such as Nginx or HAProxy, to evenly distribute traffic among multiple Ghost servers. This allows for horizontal scaling and high availability.
- Ghost Servers: Deploy multiple instances of Ghost behind the load balancer. Each Ghost server should have a copy of the Ghost codebase and access to a shared database.
- Database: Use a separate database server to store Ghost's data. MySQL or PostgreSQL are commonly used options. Ensure the database server is properly provisioned to handle the anticipated load and has backups in place.
- File Storage: Ghost requires file storage for images and other media files. Consider using a dedicated file storage service like AWS S3 or Google Cloud Storage. This allows efficient storage and retrieval of files across multiple Ghost instances.
- Caching: Implement a caching layer using tools like Redis or Memcached. Caching can greatly improve performance by reducing the load on the database and serving frequently accessed content faster.
- Monitoring and Logging: Set up monitoring and logging tools to keep track of server metrics, performance, and errors. Services like Datadog, New Relic, or ELK stack can help in this aspect.
- Auto Scaling: Depending on the expected traffic patterns, configure auto scaling policies to automatically add or remove Ghost instances based on demand. This enables the infrastructure to scale dynamically without manual intervention.
Remember, scalability is a continuous process, and monitoring and fine-tuning the architecture based on real-time data and user feedback is essential for optimal performance.
How to deploy Ghost using a one-click installer?
To deploy Ghost using a one-click installer, you can follow these steps:
- Choose a hosting provider or platform that offers a one-click installer for Ghost. Some popular options include DigitalOcean, Vultr, and Bitnami.
- Sign up for an account on the hosting provider's website and create a new server instance or virtual machine.
- Once the server is set up, log in to the server using SSH or any other method provided by the hosting provider.
- Update the server's packages. Run the following command:
1 2 |
sudo apt update sudo apt upgrade |
- Install Node.js and Ghost-CLI. Run the following commands:
1 2 3 |
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash - sudo apt install -y nodejs sudo npm install ghost-cli@latest -g |
- Create a new directory to install Ghost and navigate into it:
1 2 |
sudo mkdir -p /var/www/ghost cd /var/www/ghost |
- Install and configure Ghost using the Ghost-CLI command:
1
|
sudo ghost install
|
During the installation process, you will be prompted to provide various details like your domain name, database configuration, and administrator email address/password.
- Once the installation is completed, start Ghost using the following command:
1
|
sudo ghost start
|
- Open your web browser and visit your domain name or server's IP address. You should see the Ghost installation page.
- Follow the on-screen instructions to set up your Ghost blog, create an administrator account, and customize the theme.
That's it! Ghost is now deployed and ready to use on your server.
