Mattermost is an open-source, self-hosted team collaboration platform built for developers and enterprises seeking complete control over their data. Known for its robust customization options and self-hosting capabilities, Mattermost is an excellent alternative to proprietary solutions like Slack. This guide offers actionable steps to deploy, configure, and manage Mattermost effectively, covering installation, reverse proxy configuration, logging, backups, updates, and unique features.
Installing Mattermost
📦 Docker/Docker Compose Setup
Deploying Mattermost with Docker Compose is straightforward and ideal for managing dependencies. Start by creating a docker-compose.yml file tailored to Mattermost:
version: "3.8"
services:
app:
image: mattermost/mattermost-team-edition:latest
container_name: mattermost-app
restart: unless-stopped
ports:
- "8065:8065"
environment:
- MM_USERNAME=admin
- MM_PASSWORD=yourpassword
- MM_DB_HOST=db:5432
volumes:
- ./mattermost/data:/mattermost/data
- ./mattermost/config:/mattermost/config
- ./mattermost/logs:/mattermost/logs
depends_on:
- db
db:
image: postgres:13
container_name: mattermost-db
restart: unless-stopped
environment:
POSTGRES_USER=mmuser
POSTGRES_PASSWORD=mmuser_password
POSTGRES_DB=mattermost
volumes:
- ./mattermost/db:/var/lib/postgresql/data
Deploy the stack using the following commands:
mkdir -p ~/mattermost && cd ~/mattermost
nano docker-compose.yml # Paste the above content into the file
docker-compose up -d # Start the Mattermost app and database
docker-compose ps # Check the status of your containers
🚀 Manual Installation
For system administrators installing Mattermost on a Linux server, follow these steps:
- Install dependencies:
sudo apt update
sudo apt install -y wget tar postgresql postgresql-contrib
- Download and extract Mattermost:
wget https://releases.mattermost.com/X.X.X/mattermost-X.X.X-linux-amd64.tar.gz
tar -xvzf mattermost-X.X.X-linux-amd64.tar.gz
sudo mv mattermost /opt
sudo mkdir -p /opt/mattermost/data
sudo useradd --system --user-group mattermost
sudo chown -R mattermost:mattermost /opt/mattermost
- Configure the database:
sudo -u postgres createuser --interactive
sudo -u postgres createdb mattermost --owner=mmuser
- Start Mattermost:
sudo -u mattermost /opt/mattermost/bin/mattermost
Configuring Nginx as a Reverse Proxy
🌐 Nginx Configuration
Set up Nginx to route HTTP traffic to Mattermost running on port 8065. Add the following server block to your Nginx configuration:
server {
listen 80;
server_name mattermost.example.com;
location / {
proxy_pass http://localhost:8065/;
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 $scheme;
}
}
Restart Nginx to apply changes:
sudo nginx -t # Test configuration for syntax errors
sudo systemctl restart nginx
🔒 SSL/TLS Setup
Secure your deployment with Let's Encrypt:
sudo apt install certbot python3-certbot-nginx
sudo certbot --nginx -d mattermost.example.com
Set up automatic renewal for SSL certificates:
sudo systemctl enable certbot.timer
sudo systemctl start certbot.timer
🛠️ Testing and Reloading Nginx
Verify that the SSL certificate and proxy are working:
curl -I https://mattermost.example.com
sudo nginx -t
sudo systemctl reload nginx
Logging and Debugging Mattermost
🗃️ Enabling Debug Logs
Debug logs provide detailed insights into Mattermost's operations. Enable them by editing the configuration file:
nano /opt/mattermost/config/config.json
Set the following values:
{
"LogSettings": {
"ConsoleLevel": "DEBUG",
"FileLevel": "DEBUG"
}
}
📄 Viewing Logs
For Docker-based installations:
docker logs mattermost-app
For manual installations:
tail -f /opt/mattermost/logs/mattermost.log
🛠️ Troubleshooting Common Issues
For errors like "Site cannot be reached," check Nginx logs:
sudo tail -f /var/log/nginx/error.log
📤 Exporting Logs
Send logs to an ELK Stack with Filebeat:
sudo apt install filebeat
sudo filebeat modules enable nginx
sudo filebeat setup -e
sudo service filebeat start
Backup and Restore
🗂️ File-Based Backups
Backup the Mattermost directory:
tar -cvzf mattermost-backup.tar.gz /opt/mattermost
🔄 Database Backups
Export the PostgreSQL database:
pg_dump -U mmuser mattermost > mattermost-db.sql
Restore the database:
psql -U mmuser mattermost < mattermost-db.sql
📅 Automated Backup Scripts
Create a cron job for periodic backups:
crontab -e
Add the following line to schedule daily backups at midnight:
0 0 * * * tar -cvzf /backup/mattermost-$(date +\%F).tar.gz /opt/mattermost && pg_dump -U mmuser mattermost > /backup/mattermost-db-$(date +\%F).sql
Updating and Upgrading Mattermost
⬆️ Updating Docker Images
Pull the latest Docker image and redeploy:
docker-compose pull
docker-compose up -d
🛠️ Manual Updates
Download the latest binary:
wget https://releases.mattermost.com/X.X.X/mattermost-X.X.X-linux-amd64.tar.gz
tar -xvzf mattermost-X.X.X-linux-amd64.tar.gz
sudo systemctl restart mattermost

Leveraging Mattermost’s Unique Features
🔧 Enabling APIs
Activate API access by editing config.json:
"ServiceSettings": {
"EnableAPIv4": true
}
Test the API with curl:
curl -i -X GET -H "Authorization: Bearer <token>" https://mattermost.example.com/api/v4/teams
🌟 Advanced Configurations
Enable custom integrations by configuring incoming webhooks:
"ServiceSettings": {
"EnableIncomingWebhooks": true
}
Deploy a webhook listener using Python:
from flask import Flask, request
app = Flask(__name__)
@app.route('/webhook', methods=['POST'])
def webhook():
data = request.json
print(data)
return "OK", 200
app.run(port=5000)
