How to Install Wiki.js on Ubuntu 22.04

Wiki.js is an open-source project that runs a wiki engine using Node. It is a fully customizable and modular wiki engine written entirely in JavaScript. Wiki.js offers some useful features and it works perfectly smooth on different operating systems and environments. In this tutorial, we will show you how to install Wiki.js on Ubuntu 22.04.


Step 1. Log in to the Server

First, log in to your Ubuntu 22.04 server using SSH as root:

ssh root@IP_Address -p Port_number

You will need to replace ‘IP_Address‘ and ‘Port_number‘ with your server’s respective IP address and SSH port number. Additionally, replace ‘root’ with the username of the system user with sudo privileges.

You can check whether you have the proper Ubuntu version installed on your server with the following command:

# lsb_release -a

You should get this output:

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04 LTS
Release: 22.04
Codename: jammy

Before starting, you have to make sure that all Ubuntu OS packages installed on the server are up to date. You can do this by running the following commands:

# apt update -y

Step 2. Install NodeJS

Wiki.js requires the NodeJS runtime environment and npm (Node package manager). We can install NodeJS from the Ubuntu default repository, but we will get an older version of NodeJS if we use this method and Wiki.js requires at least NodeJS version 14. In this step, we will install NodeJS and npm through the NodeJS repository to get the most recent version of it.

# curl -sL | sudo -E bash -

Once completed, we need to download the package information from the newly added source above.

# apt update

Next, run the following command to finally install NodeJS and NPM.

# apt install nodejs

That’s it, NodeJS and NPM are installed. You can check the installed version by executing this one-liner:

# node -v; npm -v

You will see an output like this:

root@ubuntu22:~$ node -v; npm -v

Step 3. Install MariaDB and Create a Database

Wiki.js supports several database engines, like PostgreSQL, MariaDB, MySQL, SQLite3 and MSSQL. In this step, we are going to install MariaDB server from the default Ubuntu repository. To install MariaDB server, invoke this command below:

# apt install mariadb-server

On an Ubuntu system, the MariaDB server will be running automatically upon installation. Therefore, we can now continue by creating a fresh database and database user for our Wiki.js website. Let’s log in to MySQL shell as user root and create a database for our Wiki.js website.

# mysql

Once logged in to MySQL shell, we can execute the following commands.

mysql> CREATE DATABASE wikijs;
mysql> GRANT ALL on wikijs.* to wikijs@localhost identified by 'm0d1fyth15';
mysql> \q

Make sure to create a more complicated database password, substitute m0d1fyth15 in the command above with a better and stronger one.

Step 4. Install Wiki.js

In this step, we will create a new system user and grant it with sudo privileges. We will also use this user to complete this installation. In this tutorial, we will create a new system user called ‘wikijs’, you can choose any username you like.

# useradd -m -d /opt/wikijs -U -r -s /bin/bash wikijs

Once added, we can switch to that use and do the rests.

# su - wikijs

Then, we need to download the Wiki.js installation file.

$ wget

Once downloaded, we can extract it.

$ tar -xzvf wiki-js.tar.gz

The files are extracted in /opt/wikijs, let’s proceed to the next step.

Step 5. Configure Wiki.js

The Wiki.js file has been downloaded and extracted. It is time to configure it to connect to the database we created earlier.

$ cp -a config.sample.yml config.yml

Let’s edit the config.yml file.

$ nano config.yml

Find these lines.

  type: postgres

  # PostgreSQL / MySQL / MariaDB / MS SQL Server only:
  host: localhost
  port: 5432
  user: wikijs
  pass: wikijsrocks
  db: wiki

And, change the database type ‘postgres’ with ‘mariadb’, also use port 3306 instead of 5432. The lines should look like this:

  type: mariadb

  # PostgreSQL / MySQL / MariaDB / MS SQL Server only:
  host: localhost
  port: 3306
  user: wikijs
  pass: m0d1fyth15
  db: wikijs

Save the file then exit from the editor. You can also exit from user ‘wikijs’ and back to your root or sudo user.

$ exit

Step 6. Create Systemd File

To run and manage the wikijs service, we can create a systemd file.

# nano /etc/systemd/system/wikijs.service

Insert the following into the file.


ExecStart=/usr/bin/node server



Save the file, exit, and reload the systemd daemon.

# systemctl daemon-reload

Once reloaded, we can run wikijs and enable it upon server reboot.

# systemctl enable --now wikijs

That’s it, Wiki.js should be up and running. You should be able to access it at http://YOUR_SERVER_IP_ADDRESS:3000

Step 7. Install and Configure Nginx

Wiki.js is up and running on port 3000 now. To access it on a domain or subdomain, we need to create and configure a reverse proxy. In this step, we will install Nginx and create an Nginx server block for our Wiki.js website.

# apt install nginx

On an Ubuntu system, Nginx will be up and running upon installation. Now, let’s create a server block to accomodate our Wiki.js website.

# nano /etc/nginx/sites-enabled/wikijs.conf

Insert the following into the file above.

server {
  listen 80;
  root   /opt/wikijs;

    location / {
    proxy_http_version  1.1;
    proxy_set_header    Upgrade $http_upgrade;
    proxy_set_header    Connection "upgrade";
    proxy_set_header    Host $host;
    proxy_set_header    X-Real-IP $remote_addr;
    proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header    X-Forwarded-Proto $scheme;

Make sure to adjust to the domain or subdomain you want to use.

Save the file then exit from the editor. Then, we need to restart Nginx for the changes to take effect.

# systemctl restart nginx

Now, at this point, you should be able to access Wiki.js at and complete the installation through a web browser.

Click on the Install button to continue, then you will be brought to the login page.

Log in with the email and password you created earlier. You will see the welcome page to create a page or access the administration page.

You can start working and customizing your website by accessing the backend.
