  • How to load WP Rocket Cache with WordPress into RAM with TMPFS

    WP Rocket is one of the most highly regarded WordPress caching plugins on the market. WP Rocket cache stores all the website pages as HTML files, reducing the need for WordPress to load first, then send queries to the WordPress database to find out themes, plugins, and content to load, which can be slow and also quite taxing on the server leading to increase higher loads.

    Using any caching system will give immediate benefit and improve times compared to not using a cache system in most situations, however taking it one step further is to use caching in RAM, especially for highly trafficable sites using traditional file caching systems can not be as effective with load times and speed even with SSDs, minus the large read and writes that shortens the life of the hard drive.

The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt.
