How to Self-Host a Private Chat Server (Rocket.Chat, Mattermost)

Self Hosting December 07, 2024

 



In today’s digital age, communication is key. Whether it’s for personal use, a small business, or a large enterprise, effective and secure messaging platforms are crucial for seamless collaboration. While popular chat tools like Slack and Microsoft Teams dominate the scene, many users are seeking more control, privacy, and customization options. One way to achieve this is by self-hosting your own private chat server. Two of the most popular open-source options for this purpose are Rocket.Chat and Mattermost.

Self-hosting a private chat server gives you complete control over your data and enables you to create a tailored communication environment that suits your needs. In this guide, we'll walk you through the process of setting up and managing your own chat server using Rocket.Chat or Mattermost.

What is Self-Hosting a Chat Server?

Self-hosting refers to the practice of running a software application on your own server, as opposed to using a hosted solution provided by a third-party service. When you self-host a chat server, you have control over everything—from the data stored on the server to the features and customizations you implement.

Self-hosting a private chat server offers numerous advantages, including:

  • Full control over your data: Your messages and files stay on your own infrastructure.
  • Customization: Modify the platform to suit your specific needs.
  • Enhanced privacy: Avoid relying on third-party services that might have data access or store information.
  • No vendor lock-in: You’re not tied to any particular service provider’s terms and conditions.

Popular open-source chat platforms such as Rocket.Chat and Mattermost are designed for easy self-hosting, offering users a wide range of features similar to those of proprietary systems like Slack, but with the added benefit of control and privacy.

Why Choose Rocket.Chat or Mattermost?

Before diving into the setup, let’s compare Rocket.Chat and Mattermost to help you decide which platform best suits your needs.

Step-by-Step Guide to Self-Hosting a Private Chat Server

Prerequisites

Before we get started with the installation, there are a few requirements:

  • A server (physical or virtual) running a Linux-based OS (e.g., Ubuntu, CentOS).
  • Basic knowledge of Linux commands and access to the terminal.
  • A domain name (optional, but recommended for ease of access).
  • Docker and Docker Compose installed (we’ll use Docker for containerization).

Let’s break down the process of setting up both Rocket.Chat and Mattermost.

1. Setting Up Rocket.Chat

a. Install Dependencies

First, let’s start by installing the required dependencies on your server. For simplicity, we'll use Docker for deploying Rocket.Chat.

  1. Install Docker:

    bash
    sudo apt update
sudo apt install docker.io
sudo systemctl enable docker
sudo systemctl start docker

  2. Install Docker Compose:

    bash
    sudo apt install docker-compose

b. Deploy Rocket.Chat with Docker

Now, we’ll pull and deploy the Rocket.Chat container:

  1. Create a new directory for your Rocket.Chat setup:

    bash
    mkdir rocketchat && cd rocketchat

  2. Create a docker-compose.yml file with the following content:

    yaml
    version: '3'
services:
  rocketchat:
    image: rocketchat/rocket.chat:latest
    environment:
      - MONGO_URL=mongodb://mongo:27017/rocketchat
      - ROOT_URL=http://localhost:3000
      - Accounts_UseSSL=true
    ports:
      - "3000:3000"
    depends_on:
      - mongo
    restart: always

  mongo:
    image: mongo:4.0
    restart: always

  3. Start the Rocket.Chat service:

    bash
    sudo docker-compose up -d

Once the container is up and running, you can access Rocket.Chat by navigating to http://your-server-ip:3000 in a browser.

c. Configure Rocket.Chat

After the server is running, you can configure Rocket.Chat through the web interface. You’ll need to set up an admin account and configure essential settings like email, branding, and security.

2. Setting Up Mattermost

a. Install Dependencies

Similar to Rocket.Chat, we’ll use Docker to set up Mattermost.

  1. Install Docker (if not already installed):

    bash
    sudo apt update
sudo apt install docker.io
sudo systemctl enable docker
sudo systemctl start docker

  2. Install Docker Compose:

    bash
    sudo apt install docker-compose

b. Deploy Mattermost with Docker

  1. Create a new directory for Mattermost:

    bash
    mkdir mattermost && cd mattermost

  2. Create a docker-compose.yml file for Mattermost with the following content:

    yaml
    version: '3'

services:
  mattermost:
    image: mattermost/mattermost-team-edition
    environment:
      - MM_DB_HOST=mattermost-db:3306
      - MM_DB_USER=mattermost
      - MM_DB_PASSWORD=mattermost-password
      - MM_DB_NAME=mattermost
      - MM_SERVICESETTINGS_SITEURL=http://localhost:8065
    ports:
      - "8065:8065"
    depends_on:
      - mattermost-db
    restart: always

  mattermost-db:
    image: mysql:5.7
    environment:
      - MYSQL_ROOT_PASSWORD=mattermost
      - MYSQL_USER=mattermost
      - MYSQL_PASSWORD=mattermost-password
      - MYSQL_DATABASE=mattermost
    restart: always

  3. Start Mattermost:

    bash
    sudo docker-compose up -d

Once the container is up, you can access Mattermost at http://your-server-ip:8065.

c. Configure Mattermost

After installation, navigate to the Mattermost web interface to configure the platform. Similar to Rocket.Chat, you’ll need to create an admin account and set up your system preferences, integrations, and security settings.

Best Practices for Managing Your Self-Hosted Chat Server

1. Security

  • SSL Encryption: Secure your server with SSL (e.g., using Let’s Encrypt) to ensure that communication between clients and your server is encrypted.
  • Firewall Configuration: Restrict access to your server using a firewall (e.g., UFW on Ubuntu) to allow only necessary ports.
  • Regular Backups: Set up automated backups to prevent data loss. Backup both the database and the file system.

2. Scalability

  • Load Balancing: If you anticipate a large number of users, consider deploying a load balancer to distribute traffic across multiple instances of Rocket.Chat or Mattermost.
  • Database Scaling: Ensure that your database is capable of handling the load by using a scalable solution like MongoDB (for Rocket.Chat) or MySQL (for Mattermost).

3. Monitoring

  • System Monitoring: Use tools like Prometheus or Grafana to monitor server performance and ensure that your chat server runs smoothly.
  • Chat Server Health: Keep track of your Rocket.Chat or Mattermost service’s uptime and resource usage to address any issues before they affect users.
