In this tutorial, we will show you how to install Mattermost on Ubuntu 22.04 LTS. For those of you who didn’t know, Mattermost is an open-source, self-hosted chat and collaboration platform that is designed for modern teams. It is similar to other chat platforms like Slack, but it is designed to be more flexible and customizable, with a focus on security and privacy. One of the main advantages of Mattermost is its flexibility and customization options. It can be easily integrated with other tools and services, such as GitLab and JIRA, and it can be customized to meet the specific needs of a team. It is also highly scalable, with support for large organizations and distributed teams.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘
sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Mattermost on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.
- A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- SSH access to the server (or just open Terminal if you’re on a desktop).
- An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Mattermost.
non-root sudo useror access to the
root user. We recommend acting as a
non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
Install Mattermost on Ubuntu 22.04 LTS Jammy Jellyfish
Step 1. First, make sure that all your system packages are up-to-date by running the following
apt commands in the terminal.
sudo apt update sudo apt upgrade sudo apt install dirmngr gnupg apt-transport-https ca-certificates software-properties-common
Step 2. Installing PostgreSQL Database Server.
By default, PostgreSQL is available on Ubuntu 22.04 base repository. Now run the following command below to install the latest version of PostgreSQL to your system:
sudo apt install postgresql postgresql-contrib
Once successfully installed, enable PostgreSQL (to start automatically upon system boot), start, and verify the status using the commands below:
sudo systemctl enable postgresql sudo systemctl start postgresql sudo systemctl status postgresql
Next, run the command below to log in to the PostgreSQL you just installed above:
sudo --login --user postgres psql
Then, we create the Mattermost database:
postgres=# CREATE DATABASE mattermostdb; postgres=# CREATE USER mmuser WITH PASSWORD 'mmuser-password'; postgres=# GRANT ALL PRIVILEGES ON DATABASE mattermost to mmuser; postgres=# \q

Step 3. Installing Mattermost on Ubuntu 22.04.
By default, Mattermost is not available on Ubuntu 22.04 base repository. Now run the following command below to download the latest version of Mattermost to your Ubuntu system:
Next, extract the archive:
tar -xvzf mattermost*.gz
Move the extracted files to the
sudo mv mattermost /opt
Create the data storage directory for the Mattermost server.
sudo mkdir /opt/mattermost/data
Step 4. Create a user for Mattermost.
You’ll need to create a Mattermost system user and group to launch the service:
sudo useradd --system --user-group mattermost
Verify it is a system user using the command below:
Next, you’ll need to change the ownership of the Mattermost directory to the Mattermost user that you just created. To do this, enter the following command:
sudo chown -R mattermost:mattermost /opt/mattermost
Step 5. Configure Mattermost Server.
Now open the configuration file
Find the variable
DriverName under the
SqlSettings and change its value to
Set the variable
DataSource to the following value. Replace
mmuser with the SQL username,
YourPassword23! with the SQL password, and
mattermostdb with the database name, you configured in step 2.
Step 6. Create a Systemd Service for Mattermost.
Now we create a
systemd service file to manage the Mattermost service:
Add the following file:
[Unit] Description=Mattermost After=network.target After=postgresql.service BindsTo=postgresql.service [Service] Type=notify ExecStart=/opt/mattermost/bin/mattermost TimeoutStartSec=3600 KillMode=mixed Restart=always RestartSec=10 WorkingDirectory=/opt/mattermost User=mattermost Group=mattermost LimitNOFILE=49152 [Install] WantedBy=multi-user.target
Save and close the file, then reload the
systemd daemon with the following command:
sudo systemctl daemon-reload sudo systemctl start mattermost sudo systemctl enable mattermos
Step 7. Configure Firewall.
Now we set up an Uncomplicated Firewall (UFW) with Apache to allow public access on default web ports for 8065:
sudo ufw allow OpenSSH sudo ufw allow 8065 sudo ufw enable
Step 8. Accessing Mattermost Web Interface.
Once successfully installed, open your web browser and access the Mattermost installation wizard using the URL
http://your-IP-address:8065. You will be redirected to the following page:
