Wiki.js doesn’t need a database; instead, it saves all your content directly into Markdown (.md) files, making it easier to manage and back. Following the steps mentioned in the article, you can successfully install Wiki.js on Ubuntu Linux and use it for your wiki needs.

Install Git

Git is required to run Wiki.js. Git comes on the Ubuntu server. Therefore, you might not need to install it. However, if you need the latest version of Git, add the repository below and install it from it.

sudo add-apt-repository -y ppa:git-core/ppa
sudo apt update && sudo apt upgrade
sudo apt install git

After that, the latest version of Git should be installed and ready to use.

Install Node.js

Another requirement for Wiki.js is Node.js. Wiki.js is built on Node.js and therefore required. Run the commands below to install Node.js.

sudo apt install curl
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt install -y nodejs

After that, Node.js should be installed and ready to use as well.

Install MongoDB

MongoDB is also one of the requirements for Wiki.js. First, install the version in the Ubuntu repository. To install MongoDB, run the commands below.

sudo apt install mongodb

That should do it.

Download and Install Wiki.js

Now that all the requirements have been met download the Wiki.js install script. To do that, run the commands below.

sudo mkdir /var/www/wikijs
cd /var/www/wikijs
curl -sSo- https://wiki.js.org/install.sh | sudo bash

You should see a success message after installing.
