Retrieve the WikiJS Source Files

Firt connect to your SSH console.

Then, enter the following commands.

$ cd /srv/data/web/vhosts/default
$ wget wget
$ tar xvf wiki-js.tar.gz
$ rm wiki-js.tar.gz
$ mv config.sample.yml config.yml

The commands will do the following:

  • Go to your website default folder.

  • Download the lastest release of wiki.js.

  • Extract the archive

  • Rename the sample configuration file from config.sample.yml to config.yml.

Adapt your Configuration File

Next, open the config.yml file, and change the following lines. Replace “USER”, “PASSWORD”, and “DATABASE” with the username, password, and database you just created.

# ---------------------------------------------------------------------
# Port the server should listen to
# ---------------------------------------------------------------------

port: 8080

# ---------------------------------------------------------------------
# Database
# ---------------------------------------------------------------------

 type: postgres

 # PostgreSQL / MySQL / MariaDB / MS SQL Server only:
 host: localhost
 port: 5432
 user: USER
 ssl: false

Then, save your changes.

Finalize the Install

Restart Node:

Open the control panel for your web hosting. The link to your control panel can be found on the “Administration” tab of your web hosting.

In the “Node.js” section, click “Reload application”.

Run the Web Installer :

Open your website in a browser and follow the installation process, filling in the information asked for.


If the page displays a 500 error, relaunch node from your admin panel again, as described in the previous step, then connect again to your website’s URL.

Congratulations, your brand new wiki is online! You can find instructions on where to go from here in the official Wiki.js documentation.

Update your Version

When it’s time to upgrade your Wiki.js to the next version, you can start by connecting to your :ref:`SSH console <emergency_console>`_.

Next, use the following commands. Make sure to replace “MYSITE” with the name of your site.

cd /srv/data/web/vhosts/MYSITE/default
cp config.yml ~/config.yml.back
tar xvf wiki-js.tar.gz
rm wiki-js.tar.gz
cp ~/config.yml.back config.yml

These commands will do the following:

  • Go to your website root folder.

  • Save your config file.

  • Retrieve the latest version of wiki.js.

  • Extract the files.

  • Restore your config file.
