Wiki.js is a modern and powerful open-source Wiki platform built on Node.js and MongoDB. It provides an easy-to-use interface for creating, editing, and organizing content, making it a great choice for documentation and collaboration. In this article, we will go over how to install Wiki.js on Rocky Linux 9.

Prerequisites

Before we begin, there are a few things that you need to have in place in order to install Wiki.js on Rocky Linux 9:

• A computer running Rocky Linux 9.
• A user account with sudo privileges.
• A working internet connection.
• Git and Node.js installed on your system. If you don’t have these installed, you can install them by running the following commands:

sudo yum install git nodejs

Installing MongoDB

Wiki.js requires a MongoDB database to store its data. If you don’t already have MongoDB installed, you can follow these steps to install it:

Import the MongoDB public GPG key using the following command:

sudo rpm --import <https://www.mongodb.org/static/pgp/server-4.4.asc>

Add the MongoDB repository to your system by creating a new file called mongodb-org-4.4.repo in the /etc/yum.repos.d directory:

sudo nano /etc/yum.repos.d/mongodb-org-4.4.repo

Add the following contents to the file:

[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc

Save the file and exit the editor.

Install the MongoDB package by running the following command:

sudo yum install mongodb-org

Once the installation is complete, start the MongoDB service using the following command:

sudo systemctl start mongod

Verify that the MongoDB service is running by checking its status:

sudo systemctl status mongod

The output should look something like this:

● mongod.service - MongoDB Database Server
   Loaded: loaded (/usr/lib/systemd/system/mongod.service; enabled; vendor preset: disabled)
   Active: active (running) since Mon 2021-09-07 15:33:31 UTC; 3min ago
