Open source integrated monitoring software "Zabbix
Zabbix is an open source integrated monitoring software for centralized monitoring of servers, networks and applications. It provides monitoring, fault detection and notification functions required for integrated monitoring. With Zabbix agent and SNMP support for many platforms, you can monitor your entire system with a single Zabbix.
To run Zabbix, you will need the PHP programming language, MySQL as a database server, and a web server such as Apache or Nginx. In this article, we will assume that all of these have already been configured.
1. Install Zabbix
1.1 Configure Zabbix repository
Zabbix official team provides Apt package repository for Debian based systems. To add a repository to a Debian system, use the following command
|
1 |
# wget https://repo.zabbix.com/zabbix/6.0/debian/pool/main/z/zabbix-release/zabbix-release_6.0-4+debian$(cut -d"." -f1 /etc/debian_version)_all.deb |
|
1 |
# dpkg -i zabbix-release_6.0-4+debian$(cut -d"." -f1 /etc/debian_version)_all.deb |
1.2 Installing Zabbix Server
Once you have added the Apt repository, install the Zabbix server package using the following command
Package zabbix-server-mysql contains Zabbix server with MySQL support.
Package zabbix-frontend-php provides a web interface to Zabbix server.
|

# apt update # apt -y install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent |
1.3 Create Zabbix database and user
Create database schema for Zabbix server.
Login to MySQL server as root account and create MySQL database (e.g. my_zabbix_db), user (e.g. zabbix_user) and password (e.g. WWWabcd123).
|
1 2 3 4 5 6 7 |
# mysql -u root -p Password: > CREATE DATABASE my_zabbix_db character set utf8 collate utf8_bin; >CREATE USER 'zabbix_user'@'localhost' IDENTIFIED BY '?WWabcd123'; >GRANT ALL PRIVILEGES ON my_zabbix_db.* TO 'zabbix_user'@'localhost' WITH GRANT OPTION; >FLUSH PRIVILEGES; >exit; |
Load Zabbix default schema for database
|
1 2 |
# zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix_user -p'?WWabcd123' my_zabbix_db Enter Password: |
1.4 Update Zabbix configuration
Edit Zabbix server configuration file /etc/zabbix/zabbix_server.conf and update database configuration for Zabbix server to connect to database
|
1 2 3 4 5 6 7 8 9 |
# vi /etc/zabbix/zabbix_server.conf # Line 93 : Uncomment DBHost=localhost # Line 105 : change DBName=my_zabbix_db # Line 121 : change DBUser=zabbix_user # Line 129 : change DBPassword=[zabbix_user password] |
Configure Zabbix service to start at system startup.
|
1 2 |
# systemctl enable zabbix-server # systemctl restart zabbix-server |
1.5 Monitor Zabbix server itself
|
1 2 |
# systemctl enable zabbix-agent # systemctl restart zabbix-agent |
1.6 Zabbix frontend Configure
|
1 2 3 4 |
# vi /etc/zabbix/apache.conf Line 30: # php_value date.timezone Europe/Riga" Uncomment and set the time zone appropriate for your country. In the example, Japan php_value date.timezone Asia/Tokyo |
|
1 2 |
# systemctl restart apache2 # systemctl enable apache2 |
1.7 Configure Zabbix firewall
Allow Zabbix ports 10050 (Zabbix server side) and 10051 (zabbix agent side)
|
1 2 3 |
# ufw allow 10050/tcp # ufw allow 10051/tcp # ufw reload |
2. Running Zabbix Web Installer
