  • How To Migrate WordPress Manually To New Host

    Any website migration is regarded as one of the most difficult operations. Fortunately, WordPress provides a plethora of backup plugins to help and automate the entire backup and migration process. However, WordPress is constructed in such a way that manually migrate WordPress could not be simpler.

    In this tutorial, I’ll show you how to migrate a WordPress site manually to a new host or server. This is especially useful if the site is hosted on a server with insufficient resources to enable the backup plugin. Backup plugins typically demand a minimal amount of resources to execute site backup and migration to another server. I’ve prepared a list of backup plugins for WordPress. So, if your server is healthy and has sufficient resources, I recommend that you install a backup plugin for WordPress migration.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. 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. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
