Introduction

“Zabbix is the ultimate enterprise-grade software designed to monitor millions of metrics collected from thousands of servers, virtual machines and network devices in real time.” The new Zabbix 5.0 LTS has many new features and beautiful improvements. If you are interested in understanding the new LTS version provides you with features, please visit Official release page Check out the exquisite buffet. In this guide, we will install and configure Zabbix 5 LTS on Debian 10 Buster.

What’s new in Zabbix 5.0

Listed below is just the first layer of onions.

Vertical menu: The modern vertical menu in the sidebar replaces the horizontal menu in the new version.
Test items in the UI: Previously, it was difficult to determine whether the newly configured items were correctly configured. In the new version, you can even test the project (template project, project prototype, low-level discovery rules) from the user interface before saving. If the configuration is correct, you can return the true value.
Copy and paste widgets: you can copy and paste dashboard widgets into the new version
Manage a large number of hosts: Several improvements have been made to make the work of using a large number of hosts and other elements easier.
IPMI sensor discovery: Added a new ipmi.get IPMI item, which returns JSON with information about the IPMI sensor
Secure connection to Zabbix database: You can now configure a secure TLS connection to MySQL and PostgreSQL databases from the Zabbix front-end or server.
Stronger password encryption: stronger bcrypt encryption is now used to hash user passwords instead of MD5
SAML authentication: Login to Zabbix now supports SAML 2.0 authentication.
Webhook integration: Push Zabbix notifications to (Microsoft Teams, Jira, Telegram, Zendesk, Redmine, etc.)
Resources: Zabix

Even better, we will install version 5.0 of Zabbix Server in Debian 10 (Buster). Please complete our work together.

Step 1: Add Zabbix repository

Run the following command to install Zabbix repository

sudo apt update && sudo apt install wget
wget https://repo.zabbix.com/zabbix/5.0/debian/pool/main/z/zabbix-release/zabbix-release_5.0-1+buster_all.deb
sudo apt install ./zabbix-release_5.0-1+buster_all.deb

Step 2: Install Zabbix server

Zabbix comes with three components, server, agent and front end. The agent is optional.

Install Zabbix server

This will install MariaDB database server on Debian 10 (Buster).

sudo apt update
sudo apt install zabbix-server-mysql

Check the installed version by running the following command

$ mariadb --version
mariadb  Ver 15.1 Distrib 10.3.22-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

Step 3: Configure and create Zabbix server database

Run the following command, then say “Yes (Y) (Y)” to delete anonymous users, delete the test database and disable remote root login.

$ sudo mysql_secure_installation
Enter current password for root (enter for none):
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] y
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y

sudo mysql -u root -p

Create Zabbix database and Zabbix users:

CREATE DATABASE zabbixdb character set utf8 collate utf8_bin;
GRANT ALL PRIVILEGES ON zabbixdb.* TO [email protected] IDENTIFIED BY 'SafePassWord';
FLUSH PRIVILEGES;
QUIT

Import Zabbix database data

Now, use MySQL to import the initial architecture and data of the server. After issuing this command, please take some time to complete it.

$ sudo zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uuserzabbix -p zabbixdb
Enter password: SafePassWord (The password you set above for userzabbix)

Step 4: Configure the database for the Zabbix server

Open the Zabbix server configuration file and make the changes shown below. If you use different databases and usernames, please update them accordingly.

sudo vim /etc/zabbix/zabbix_server.conf

Set the configuration of the database connection as follows.

DBHost=localhost          ##Uncomment this option
DBName=zabbixdb           ##Key in the database name you configured
DBUser=userzabbix         ##Key in the user name you configured
DBPassword=SafePassWord   ##Key in the password you configured

Step 5: Install the Zabbix front end

This will install Nginx and PHP on Debian Linux.

sudo apt install zabbix-frontend-php zabbix-nginx-conf

Check the installed version of Nginx and PHP

$ nginx -v
nginx version: nginx/1.14.2

$ php -v
PHP 7.3.11-1~deb10u1 (cli) (built: Feb 16 2020 15:07:23) ( NTS )

Configure the PHP date.timezone parameters used by Zabbix in its settings

$ sudo vim /etc/php/7.3/fpm/php.ini
[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = Africa/Nairobi      ## Set your timezone here

Restart php-fpm

sudo systemctl restart php7.3-fpm

Start and enable Nginx

sudo systemctl enable nginx
sudo systemctl start nginx

Configure Nginx

Zabbix creates its own Nginx configuration file. Open and uncomment the “listen” and “server_name” sections as shown below

$ sudo vim /etc/nginx/conf.d/zabbix.conf
server {
listen 80;                          ## Uncomment this part
server_name computingforgeeks.com;  ## Uncomment this part too

Change the port of the “default” Nginx file in Debian to listen to other ports so that it does not conflict with Zabbix configured above.

$ sudo vim /etc/nginx/sites-available/default
server {
listen 82 default_server;        ## Change from 80 to 82
listen [::]:82 default_server;   ## Change from 80 to 82 as well

Change permissions of Zabbix root folder

sudo chmod -R 775 /usr/share/zabbix/

Restart Nginx

sudo systemctl restart nginx

Step 6: Install Zabbix Agent on Debian 10 (Buster)

The agent will monitor the server itself

To install the agent, run

sudo apt install zabbix-agent

Start and enable zabbix agent and server

sudo systemctl enable zabbix-server zabbix-agent
sudo systemctl start zabbix-server zabbix-agent

Step 7: Set up the Zabbix web interface

Open your favorite browser and enter the IP of the Zabbix server. The mine is shown below. Click “Next”.

http://172.17.37.54

You should see the next page similar to the image below. Make sure all prerequisites are recorded as green “OK” and click “Next”

You should see the next page similar to the one shown below, asking for database details.

Enter the database details we set up earlier. If you want to encrypt in the database connection, you can configure TLS in this step. When finished, click “Next”

Enter your Zabbix server details (including server name) (if necessary), and then click “Next”. You should see the installation summary. Just click “Next”

Next, just click “Finish” to complete the setup

Step 8: Log in to Zabbix

After completing step 5, you will be redirected to the login page as shown below. Zabbix’s default login credentials are:

username: administratorPassword: zabbix

Remember, you can management After logging in, enter the tab page.

Navigation Administration> Users> Administrator> Password> Change Password

in conclusion

The new Zabbix Server 5.0 LTS can now run on Nginx, we hope everything goes well. Review the new features implemented and try all the configurations required by the environment. Otherwise, we would like to thank you for taking the time to blog, and thank you for your continued support.
