How to Install Mattermost on OpenSUSE Latest?

Mattermost is an open-source messaging and team collaboration platform that allows you to transform your workplace communication into one central place. In this tutorial, we will guide you through the installation of Mattermost on OpenSUSE Latest.

Prerequisites

Before we proceed with the Mattermost installation, you need to ensure that your server meets the following requirements:

• OpenSUSE Latest installed on your server
• Root access to the server
• An active internet connection

Step 1: Update the System

It is always recommended to update your system to the latest version before installing any new software. To update your system, run the following command:

sudo zypper update

Step 2: Install Database Server

Mattermost requires a database server to store its data. In this tutorial, we will use PostgreSQL as our database server. To install PostgreSQL, run the following command:

sudo zypper install postgresql

Once the installation is complete, start the PostgreSQL service and enable it to start on boot with the following commands:

sudo systemctl start postgresql
sudo systemctl enable postgresql

Step 3: Create a Database and User for Mattermost

After installing PostgreSQL, you need to create a new database and user for Mattermost. To do this, follow these steps:

1. Log in to the PostgreSQL shell by running the following command:

sudo -u postgres psql

2. Create a new database for Mattermost by running the following command:

CREATE DATABASE mattermost;

3. Create a new user and give it access to the Mattermost database by running the following command:

CREATE USER mattermost WITH PASSWORD 'password';
GRANT ALL PRIVILEGES ON DATABASE mattermost TO mattermost;

Replace 'password' with a strong password of your choice.

4. Exit the PostgreSQL shell using the following command:

\q

Step 4: Install Mattermost Server

Now it's time to download and install Mattermost Server. To do this, follow these steps:

1. Download the latest stable version of Mattermost Server from the official website:

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

Replace X.X.X with the latest version number.

2. Extract the downloaded file using the following command:

tar -xvzf mattermost-X.X.X-linux-amd64.tar.gz

3. Move the extracted directory to the /opt directory:

sudo mv mattermost /opt/

4. Create a new system user for Mattermost:

sudo useradd --system --user-group mattermost

5. Change the ownership of the Mattermost installation directory to the new system user:

sudo chown -R mattermost:mattermost /opt/mattermost

Step 5: Configure Mattermost Server

In this step, we will configure the Mattermost server to use the PostgreSQL database that we created earlier.

1. Edit the Mattermost configuration file using the following command:

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

2. Find the following configurations in the file and update the values as shown below:

"DriverName": "mysql"  => "DriverName": "postgres",
"DataSource": "mmuser:mostest@tcp(dockerhost:3306)/mattermost_test?charset=utf8mb4,utf8" => "DataSource": "postgres://mattermost:password@localhost/mattermost?sslmode=disable&connect_timeout=10",
"SqlServer": "mysql://mmuser:mostest@tcp(dockerhost:3306)/mattermost_test?charset=utf8mb4,utf8" => "SqlServerSettings": {
    "DriverName": "postgres",
    "DataSource": "postgres://mattermost:password@localhost/mattermost?sslmode=disable&connect_timeout=10",
    "DataSourceReplicas": [],
    "DataSourceSearchReplicas": [],
    "MaxIdleConns": 20,
    "ConnMaxLifetimeMilliseconds": 3600000,
    "MaxOpenConns": 300
},

3. Save and exit the file.

Step 6: Start Mattermost Server

Now, it's time to start the Mattermost server.

1. Switch to the Mattermost user account:

sudo su - mattermost

2. Start the Mattermost server:

cd /opt/mattermost
./bin/mattermost

You should see an output similar to the following:

{"level":"info","ts":1615566989.8111653,"caller":"app/server.go:209","msg":"Starting Server..."}
