Ghost CMS is a popular platform for bloggers and content creators, known for its simplicity and elegant design.

Using PM2 for process management in Ghost CMS provides several benefits.

Firstly, PM2 allows for easy process monitoring, enabling users to keep track of their Ghost CMS instances and quickly identify any issues.

Additionally, PM2 offers automatic restarts in case of crashes, ensuring GhostCMS remains operational without manual intervention.

Lastly, PM2 provides a centralized dashboard for managing multiple Ghost CMS instances, simplifying management for bloggers and content creators.

However, managing the Ghost process can sometimes be a challenge, especially when it comes to stability and efficient resource utilization.

Because I run Ghost on shared hosting, I use PM2.In shared hosting, I can't take advantage of systemd since it requires superuser permission.

Understanding PM2

PM2 is a production-ready process manager for Node.js applications.

It provides robust features, including automatic restarts, load balancing, and monitoring.

By leveraging PM2's capabilities, you can streamline your Ghost CMS process management and ensure seamless operation.

Without PM2, managing the Ghost CMS process can be time-consuming and inefficient. You would need to manually monitor the process, restart it in case of crashes, and manage multiple instances separately.
