Open-source integrated monitoring software "Zabbix7"

Zabbix is open-source integrated monitoring software for centralized monitoring of servers, networks, and applications. It provides the monitoring, fault detection, and notification functions necessary for integrated monitoring. With Zabbix agents supporting numerous platforms and SNMP compatibility, it enables monitoring of entire systems using just Zabbix.

To run Zabbix, you need the PHP programming language, a MySQL/MariaDB database server, and a web server such as Apache or Nginx.
This guide assumes all of the following conditions are already configured.

This time, we will install Zabbix 7.4.3, released on October 1, 2025, in the following environment.
Apache/2.4.65
11.8.3-MariaDB
PHP 8.4.11 php-fpm

Zabbix 7 Server、Frontend、Agent Install

Install the repository
Configure the Zabbix 7 repository and install the Zabbix server.
Simultaneously install the necessary Zabbix Agent on the monitored hosts so that the Zabbix server itself can also be monitored.

# wget https://repo.zabbix.com/zabbix/7.4/release/debian/pool/main/z/zabbix-release/zabbix-release_latest_7.4+debian13_all.deb

# dpkg -i zabbix-release_latest_7.4+debian13_all.deb

# apt update

# apt -y install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent2 php-mysql php-gd php-bcmath php-net-socket

# wget https://repo.zabbix.com/zabbix/7.4/release/debian/pool/main/z/zabbix-release/zabbix-release_latest_7.4+debian13_all.deb

# dpkg -i zabbix-release_latest_7.4+debian13_all.deb

# apt update

# apt -y install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent2 php-mysql php-gd php-bcmath php-net-socket

Create a database and user for Zabbix

Create the database schema for the Zabbix server.
Log in to the MariaDB server as the root account and create a MariaDB database (e.g., my_zabbix_db), a user (e.g., zabbix_user), and a password (e.g., ?WWabcd123).

# mariadb -uroot -p
password
mysql> create database my_zabbix_db character set utf8mb4 collate utf8mb4_bin;
mysql> create user zabbix_user@localhost identified by '?WWabcd123';
mysql> grant all privileges on my_zabbix_db.* to zabbix_user@localhost;
mysql> set global log_bin_trust_function_creators = 1;
mysql> quit;

# mariadb -uroot -p

password

mysql> create database my_zabbix_db character set utf8mb4 collate utf8mb4_bin;

mysql> create user zabbix_user@localhost identified by '?WWabcd123';

mysql> grant all privileges on my_zabbix_db.* to zabbix_user@localhost;

mysql> set global log_bin_trust_function_creators = 1;

mysql> quit;

Load the default schema for Zabbix into the database

# zcat /usr/share/zabbix/sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix_user -p'?WWabcd123' my_zabbix_db

1	# zcat /usr/share/zabbix/sql-scripts/mysql/server.sql.gz \| mysql --default-character-set=utf8mb4 -uzabbix_user -p'?WWabcd123' my_zabbix_db

After importing the database schema, disable the log_bin_trust_function_creators option.

# mariadb -uroot -p
password
mysql> set global log_bin_trust_function_creators = 0;
mysql> quit;

# mariadb -uroot -p

password

mysql> set global log_bin_trust_function_creators = 0;

mysql> quit;

Update Zabbix Configuration

Edit the Zabbix server configuration file /etc/zabbix/zabbix_server.conf to update the database settings so the Zabbix server can connect to the database.

# vi /etc/zabbix/zabbix_server.conf

Change line 100
DBName=my_zabbix_db
Change line 116
DBUser=zabbix_user
Uncomment line 124 and add the following
DBPassword=?WWabcd123

# vi /etc/zabbix/zabbix_server.conf

Change line 100

DBName=my_zabbix_db

Change line 116

DBUser=zabbix_user

Uncomment line 124 and add the following

DBPassword=?WWabcd123

Monitor the Zabbix server itself

# vi /etc/zabbix/zabbix_agent2.conf

# Line 146: Change to your own hostname
Hostname=Lepard

# vi /etc/zabbix/zabbix_agent2.conf

# Line 146: Change to your own hostname

Hostname=Lepard

Restart the Zabbix server and agent daemons and enable them to run at system startup.

# systemctl enable zabbix-server zabbix-agent2 apache2
# systemctl restart zabbix-server zabbix-agent2 apache2
