Installing Wiki.js (PostgreSQL, NGINX) on AlmaLinux 10

Mon, 30 Jun 2025 19:35:00 +0000

This guide demonstrates installing Wiki.js, the NGINX reverse proxy, Certbot (an ACME client that we’ll use for automated SSL certificate renewal), a backing PostgreSQL database, and a supporting Elasticsearch container on an AlmaLinux 10 server.

Wiki.js is a Node.js application that relies on a database - we’ll be using PostgreSQL.

We’ll put a NGINX reverse proxy in front of the Wiki.js web application to handle SSL, and configure Wiki.js to listen on only localhost (127.0.0.1:3000) so that only NGINX is exposed to the outside world.
