Installing Zabbix on nixOS Latest

Zabbix is an open-source monitoring software that allows system administrators to keep track of network services, servers, and other IT infrastructure components. nixOS is a Linux distribution known for its declarative configuration management system, functional package manager, and reliable roll-back features. In this tutorial, we will guide you through the process of installing Zabbix on nixOS latest.

Prerequisites

Before we begin, make sure to have the following requirements:

  • A machine with nixOS latest installed.
  • sudo privileges to the user account.

Step 1: Update the system

To ensure that our system is up to date, run the following command:

sudo nix-channel --update && sudo nixos-rebuild switch

This will update the nixOS channels and roll out the changes to the system configuration.

Step 2: Prepare the environment for Zabbix

We will install some of the necessary packages that we need for the installation of Zabbix. Run the following command:

sudo nix-env -i bash wget curl unzip iproute2 postgresql python python-pip python-setuptools

This command will install Bash, wget, curl, unzip, iproute2, PostgreSQL, Python, pip, and setuptools.

Step 3: Install Zabbix

Now that we have prepared our environment, we can proceed to install Zabbix. We will use the nix-env command to install it.

sudo nix-env -i zabbix

This command will install the Zabbix package and its dependencies.

Step 4: Configure Zabbix

After the installation, we need to configure our Zabbix server. We will configure the following components:

  1. Database
  2. Web server
  3. Zabbix server and agent

4.1 Create a PostgreSQL user and database

First, create a new PostgreSQL user and database for Zabbix. Run the following command:

sudo -u postgres createuser --pwprompt zabbix

Enter a password for the newly created user when prompted. Next, create a new database for Zabbix:

sudo -u postgres createdb -O zabbix -E Unicode -T template0 zabbix

4.2 Configure the web server

To configure the web server, we need to set up the Zabbix front-end. We will use Apache as our web server.

sudo nix-env -i apacheHttpd

This command will install Apache.

Next, we need to edit the /etc/httpd/conf/httpd.conf file to add the Zabbix configuration. Add the following lines:

Listen 80
<VirtualHost *:80>
    DocumentRoot "/var/zabbix/frontend/php/"
    ServerName YOUR_SERVER_NAME_OR_IP
    ServerAlias YOUR_ALIASES
    <Directory "/var/zabbix/frontend/php/">
        AllowOverride All
        Require all granted
    </Directory>
    ErrorLog "/dev/stderr"
    CustomLog "/dev/stdout" combined
</VirtualHost>

Replace YOUR_SERVER_NAME_OR_IP with the domain name or IP address of your server, and YOUR_ALIASES with any additional domain names or aliases that you want to associate with this server.

4.3 Configure the Zabbix server and agent

Next, edit the /etc/zabbix/zabbix_server.conf file and uncomment the following lines:

DBName=zabbix
DBUser=zabbix
DBPassword=YOUR_PASSWORD

Replace YOUR_PASSWORD with the password you set for the Zabbix user in step 4.1.

Now, start the Zabbix server and agent:

sudo systemctl start zabbix-server zabbix-agent

Then, enable them to start at boot:

sudo systemctl enable zabbix-server zabbix-agent

Step 5: Access Zabbix

Now that we have completed the installation and configuration, we can access the Zabbix web interface by navigating to:

http://YOUR_SERVER_NAME_OR_IP

Then, log in with the default credentials:

  • Username: Admin
  • Password: zabbix

Conclusion

We have successfully installed and configured Zabbix on nixOS latest. You can now monitor your IT infrastructure components by adding hosts and setting up monitoring items, triggers, and alerts.
