Ubuntu 20.04 LTS:
 

Ubuntu 20.04.4 LTS Minimal Install; Include Updates

sudo apt install -y openssh-server

optional:

sudo apt install -y mc

Check for updates:

sudo apt update -y

Initial System Configuration:
hard-code IP address, disable IPv6; Set Update Preferences

LAMP Stack:

Apache:

sudo apt install -y apache2

 

DataBase: MariaDB or MySQL:

    1. Install MySQL OR the Open-Source MariaDB:
        MySQL:

sudo apt install -y mysql-server

       OR MariaDB:
        Using MariaDB instead of MySQL:

sudo apt install -y apt install mariadb-server

        Do Not run mysql_secure_installation as it is broken
        
    2. Create dbadmin Administrative user with a password

       

sudo mysql
CREATE USER 'dbadmin'@'localhost' IDENTIFIED WITH mysql_native_password BY '<dBadmin_pwd>';
GRANT ALL ON *.* TO 'dbadmin'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;
exit

    (Back to LAMP Installation)

 

PHP:

apt install -y php libapache2-mod-php php-mysql

Did NOT create a vHost

Test PHP:

sudo nano /var/www/html/info.php
        <?php
        phpinfo();

    Open: http://<host_ip>/info.php to verify PHP is working with Apache
    Delete the test file:

rm /var/www/html/info.php

phpMyAdmin:

 

References:

sudo apt update -y
sudo apt upgrade -y
sudo apt install -y phpmyadmin php-mbstring php-zip php-gd php-json php-curl

Configure phpmyadmin:

    Selected apache2
    Selected to Configure database for phpmyadmin
    MySQL App Password: <db_admin_pwd>

Enable mbstring:

sudo phpenmod mbstring

   
NOTE: DO NOT Configure Password Access for the MySQL Root Account

Test Connection to: http://<host_ip>/phpmyadmin/

    uid:    dbadmin
    pwd:    <db_admin_pwd>

Zabbix Installation and Base Configuration
 

We need Zabbix v5 to be able to use the NVidia GPU Templates but the Zabbix Packages supplied with Ubuntu 20.04 are Zabbix version 4 and though v5 is provided with Ubuntu 22.04 there are issues getting it running possibly due to the use of PHPv8

Zabbix: Debian Install from Packages
Zabbix: Ubuntu 20.04 Install

 

Install Zabbix repository:

sudo wget https://repo.zabbix.com/zabbix/5.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.0-1+focal_all.deb
sudo dpkg -i zabbix-release_5.0-1+focal_all.deb
sudo apt update

   
Install Zabbix server, frontend, agent:

 

Import initial schema and data:

sudo zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p <zabbix_admin_pwd>

 

Configure the database for Zabbix server:

sudo nano /etc/zabbix/zabbix_server.conf
DBPassword=<db_admin_pwd>  (DO NOT enclose Password in Quotes)

 

Configure PHP for Zabbix frontend:

sudo nano /etc/zabbix/apache.conf
php_value date.timezone America/Toronto (adjust to your locale)

 

Start Zabbix Server and Agent Processes:

sudo systemctl restart zabbix-server zabbix-agent apache2
sudo systemctl enable zabbix-server zabbix-agent apache2

 

Front-End Configuration:

 

References:

Zabbix Front-End

Open: http://<host_ip>/zabbix/

Config DB connection:

Type:    MySQL
Host:    localhost
Port:    0
Name:    zabbix
user:    zabbix
pwd:    <zabbix_admin_pwd>

Hit next until you get to the summary. If all goes well everything should be OK and you should be prompted to save the php Config file and you'll end up at the Login Screen

    uid:    Admin (note Capital "A")
    pwd:    zabbix

 

Add Local Agent to Monitored Hosts:

 

Install the agent:
    sudo apt install zabbix-agent

Configure the agent:
References:

Computing for Geeks

 

Start the agent:

sudo systemctl start zabbix-agent

Set it to start it on boot:

sudo systemctl enable zabbix-agent

Add it to the Server:

NVidia Monitoring Template:
 

Add the git package:

sudo apt install -y git make

Create a Projects area:

sudo mkdir /root/projects
sudo cd /root/projects

Clone the template from github

sudo git clone https://github.com/plambe/zabbix-nvidia-smi-multi-gpu

Install the Template:

sudo cd /root/projects/zabbix-nvidia-smi-multi-gpu
sudo make install

Open Templates in the Configuration Pane and select "Import"

Select the zbx_nvidia-smi-multi-gpu.xml file

we use zabbix at work for (some parts of) our monitoring, and this write-up absolutely helps me understanding how it works! Thanks for this one
