How to Install Mattermost on Debian

Mattermost is an open-source messaging and collaboration tool that is designed for teams, businesses, and other organizations. It is an alternative to popular messaging apps such as Slack or Microsoft Teams. In this tutorial, we will show you how to install Mattermost on Debian.

Prerequisites

Before we proceed with the installation, make sure that you have the following prerequisites:

• A server running Debian OS
• Access to a terminal
• A sudo user account

Step 1: Install Dependencies

Before installing Mattermost, you need to install some dependencies that are required for it to run. To do this, log in to your server and run the following command:

sudo apt-get update
sudo apt-get install wget nano curl docker-compose

Step 2: Install Mattermost

Once you have installed the necessary dependencies, you can now proceed with the installation of Mattermost. Follow the steps below:

1. First, navigate to the Mattermost official website by using the following command:

   wget https://releases.mattermost.com/5.23.0/mattermost-5.23.0-linux-amd64.tar.gz
   

   Note: This is the latest version of Mattermost. If you want to install a different version, replace the URL with the URL for the version you want.

2. Next, extract the downloaded file using the following command:

   tar -xvzf mattermost*.tar.gz
   

3. Move the extracted files to the Mattermost directory using the following command:

   sudo mv mattermost /opt/
   

4. Create a Mattermost user account using the following command:

   sudo useradd --system --user-group mattermost
   

5. Change the ownership of the Mattermost directory to the Mattermost user using the following command:

   sudo chown -R mattermost:mattermost /opt/mattermost
   

Step 3: Configure Mattermost

After installing Mattermost, you need to configure it before you can use it. Follow the steps below:

1. Create a new Mattermost configuration file using the following command:

   sudo nano /opt/mattermost/config/config.json
   

2. Copy the following code and paste it into the configuration file:

   {
       "ServiceSettings": {
           "ListenAddress": ":8065",
           "ConnectionSecurity": "",
           "TLSCertFile": "",
           "TLSKeyFile": "",
           "UseLetsEncrypt": false,
           "LetsEncryptCertificateCacheFile": "./config/letsencrypt.cache"
       },
       "SqlSettings": {
           "DriverName": "mysql",
           "DataSource": "mattermost:password@tcp(localhost:3306)/mattermost?charset=utf8mb4,utf8\u0026readTimeout=30s\u0026writeTimeout=30s",
           "DataSourceReplicas": [],
           "DataSourceSearchReplicas": [],
           "MaxIdleConns": 10,
           "MaxOpenConns": 10,
           "Trace": false,
           "AtRestEncryptKey": "somerandomstring",
           "QueryTimeout": 30
       }
   }
   

   Note: If you plan on using a different database, make sure to update the SqlSettings section with the appropriate information.

3. Save and close the file by pressing CTRL+X, then Y, and then ENTER.

4. Next, create a database for Mattermost by running the following command:

   mysql -u root -p
   

   This will open the MySQL/MariaDB prompt. Enter your root password when prompted.

5. Once you are in the database prompt, create a new database with the following command:

   CREATE DATABASE mattermost;
   

6. Create a new user for the Mattermost database with the following command:

   CREATE USER 'mattermost'@'localhost' IDENTIFIED BY 'password';
   

7. Grant the user access to the Mattermost database with the following command:

   GRANT ALL PRIVILEGES ON mattermost.* TO 'mattermost'@'localhost';
   

8. Refresh the database permissions with the following command:

   FLUSH PRIVILEGES;
   

9. Exit the database prompt by typing exit.

Step 4: Start Mattermost

After configuring Mattermost, you can now start it using the following commands:

cd /opt/mattermost/
sudo -u mattermost ./bin/mattermost

This will start the Mattermost server. You can access it by going to http://localhost:8065 in your web browser.

Conclusion

Congratulations! You have successfully installed Mattermost on Debian. You can now use it to collaborate with your team and improve your productivity.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
