Install Mattermost Server on Ubuntu
Minimum system requirements:
- Operating System: 18.04 LTS, 20.04 LTS, 22.04 LTS
- Hardware: 1 vCPU/core with 2GB RAM (support for up to 1,000 users)
- Database: PostgreSQL v11+
- Application 80/443, TLS, TCP Inbound
- Administrator Console 8065, TLS, TCP Inbound
- SMTP port 10025, TCP/UDP Outbound
You can install the Mattermost Server using our
.deb signed packages using the Mattermost PPA (Personal Package Archive). Using the Mattermost Personal Package Archive (PPA) not only provides the quickest way to install a Mattermost Server, but also provides automatic updates. This install method is used for both single and clustered installations.
If you are running the Mattermost Server and database on a single system, we recommend the Mattermost Omnibus install method as this greatly reduces setup and ongoing maintenance.

You need a PostgreSQL database. See the database preparation documentation for details on this prerequisite.
In a terminal window, run the following command to add the Mattermost Server repositories:
curl -o- https://deb.packages.mattermost.com/repo-setup.sh | sudo bash -s mattermostCopied to clipboard
Ahead of installing the Mattermost Server, it’s good practice to update all your repositories and, where required, update existing packages by running the following command:
sudo apt update
After any updates, and any system reboots, are complete, installing the Mattermost Server is now a single command:
sudo apt install mattermost -yCopied to clipboard
You now have the latest Mattermost Server version installed on your system.
The installation path is
/opt/mattermost. The package will have added a user and group named
mattermost. The required systemd unit file has also been created but will not be set to active.
Since the signed package from the Mattermost repository is used for mulitple installation types, we don’t add any dependencies in the systemd unit file. If you are installing the Mattermost server on the same system as your database, you may want to add both
BindsTo=postgresql.service to the
[Unit] section of the systemd unit file.
Before you start the Mattermost Server, you need to edit the configuration file. A sample configuration file is located at
Rename this configuration file with correct permissions:
sudo install -C -m 600 -o mattermost -g mattermost /opt/mattermost/config/config.defaults.json /opt/mattermost/config/config.json
Configure the following properties in this file:
"postgres". This is the default and recommended database for all Mattermost installations.
mattermostwith your database name.
"SiteURL": The domain name for the Mattermost application (e.g.
After modifying the
config.json configuration file, you can now start the Mattermost Server:
sudo systemctl start mattermost
Verify that Mattermost is running: curl
http://localhost:8065. You should see the HTML that’s returned by the Mattermost Server.
The final step, depending on your requirements, is to run
sudo systemctl enable mattermost.service so that Mattermost will start on system boot.
When a new Mattermost version is released, run:
sudo apt update && sudo apt upgrade to download and update your Mattermost instance.
When you run the
sudo apt uprade command,
mattermost-server will be updated along with any other packages. We strongly recommend you stop the Mattermost Server before running the
apt command using
sudo systemctl stop mattermost-server.
If you wish to remove the Mattermost Server for any reason, you can run this command:
sudo apt remove --purge mattermost
Why doesn’t Mattermost start at system boot?
To have the Mattermost Server start at system boot, the systemd until file needs to be enabled. Run the following command:
sudo systemctl enable mattermost.service
Why does Mattermost fail to start at system boot?
If your database is on the same system as your Mattermost Server, we recommend editing the default
/lib/systemd/system/mattermost.service systemd unit file to add
BindsTo=postgresql.service to the
We recommend the Mattermost Omnibus install method over the
deb signed package if you are running the Mattermost Server and database on a single system as this greatly reduces setup and ongoing maintenance.
Can I run Mattermost without a proxy?
Yes. Mattermost binds to 443 instead of 8065. The Mattermost binary requires the correct permissions to do that binding. You must activate the
CAP_NET_BIND_SERVICE capability to allow the new Mattermost binary to bind to ports lower than 1024 by running the following command:
sudo setcap cap_net_bind_service=+ep ./mattermost/bin/mattermost
We recommend the Mattermost Omnibus install method over the tarball if you are running the Mattermost Server and database a single system as this greatly reduces setup and ongoing maintenance.
We highly recommend using a proxy in front of Mattermost server.
