How to Install and Configure Mattermost on CentOS 7: A Comprehensive Guide

Mattermost is a powerful communication tool that enables teams to collaborate and communicate effectively. Whether you are working remotely or in an office, Mattermost’s file sharing, messaging, and video call capabilities allow teams to stay connected and productive.

In this article, we will provide a step-by-step guide on how to install Mattermost on a CentOS 7 server, including creating a MySQL database and setting up a reverse proxy with Nginx. We will also cover configuring Mattermost by creating an account and team, setting the site URL, enabling email notifications, and restarting the Mattermost service.

Prerequisites

Before we proceed to install Mattermost, there are several prerequisites we need to set up. First, we need to have a CentOS 7 server with a domain name.

We will also need to install Nginx and obtain an SSL certificate. Finally, we need to create a MySQL database and user.

We will be using MariaDB 10.3 for this purpose.

Create a MySQL database

Next, we need to create a MySQL database for Mattermost to utilize. We will use the following commands to create a new database and user:

$ sudo mysql -u root -p

> CREATE DATABASE Mattermost;

> CREATE USER ‘mmuser’@’localhost’ IDENTIFIED BY ‘mmpasswd’;

> GRANT ALL PRIVILEGES ON Mattermost.* TO ‘mmuser’@’localhost’;

> flush privileges;

Install Mattermost server

We can now install the Mattermost server on our CentOS 7 server. The Mattermost server is built on top of Golang and React, and it requires either MySQL or PostgreSQL to store data.

To install Mattermost, run the following commands:

$ wget https://releases.mattermost.com/5.26.1/mattermost-5.26.1-linux-amd64.tar.gz

$ tar -xvzf mattermost-5.26.1-linux-amd64.tar.gz

$ sudo mv mattermost /opt

After moving Mattermost to the /opt directory, we need to create a Systemd unit for Mattermost. This unit will ensure that the Mattermost service starts at boot time, and we can start the service by running systemctl start mattermost.

Create a Systemd unit

To create a Systemd unit for Mattermost, we need to create a new file /etc/systemd/system/mattermost.service. The contents of this file should be as follows:

[Unit]

Description=Mattermost

After=syslog.target network.target

[Service]

Type=simple

WorkingDirectory=/opt/mattermost/bin

ExecStart=/opt/mattermost/bin/mattermost

User=root

Group=root

Restart=always

SystemCallErrorNumber=11

[Install]

WantedBy=multi-user.target

After creating this file, we can save it and reload the Systemd daemon by running systemctl daemon-reload.

Set up a reverse proxy with Nginx

Finally, to enable HTTPS access to our Mattermost server, we need to set up a reverse proxy with Nginx and obtain an SSL certificate. The easiest way to obtain an SSL certificate is by using Let’s Encrypt.

To do this, we need to first install Certbot:

$ sudo yum install certbot python2-certbot-nginx -y

After installing Certbot, we can obtain an SSL certificate by running the following command:

$ sudo certbot –nginx -d mattermost.example.com

This will prompt us to enter our email address and agree to the terms of service. Once completed, Certbot will handle setting up the SSL certificate and configuring Nginx to use HTTPS.

Configuring Mattermost

Now that we have installed and set up Mattermost, we can begin configuring it. The first step is to create an account and team.

By default, the first account created is given administrator privileges, allowing us to set up the system to our liking.

Creating an account and team

To create an account and team, simply visit our Mattermost server’s URL and follow the on-screen prompts. We will be asked to create an email and provide a password before being redirected to the Teams page where we can create our first team.

Setting site URL

After creating our account and team, we need to set the site URL to point to our Mattermost server’s domain name. To do this, we need to navigate to Settings General > Configuration and update the Site URL field.

Enabling email notifications

Finally, to ensure that our team members receive email notifications of new messages and mentions, we need to configure Mattermost to use an SMTP server. To do this, navigate to Notifications > Email and provide the SMTP server’s parameters.

Restarting Mattermost service

After making changes to our Mattermost configuration, we need to restart the Mattermost service to ensure that the changes take effect. To do this, simply run systemctl restart mattermost.
