Zabbix installation: Distribution setup

-

 On Zabbix core server:

Step1: Install Zabbix repository

rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-latest-6.0.el8.noarch.rpm

dnf clean all


Step2:Install Zabbix server, frontend, agent

dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-selinux-policy zabbix-agent


Step3: Configure the database for Zabbix server

Edit file /etc/zabbix/zabbix_server.conf

DBHost= DBserver_ip

DBName=

DBUser=

DBPassword=

DBPort=3306


Step4: Start Zabbix server and agent processes

systemctl restart zabbix-server zabbix-agent httpd php-fpm
systemctl enable zabbix-server zabbix-agent httpd php-fpm



On Zabbix Database Server:

Step1: Install Zabbix repository

rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-latest-6.0.el8.noarch.rpm

dnf clean all


Step2: Install the sql script, zabbix agent 

dnf install zabbix-sql-scripts zabbix-selinux-policy zabbix-agent


Step3: Install the mysql server

yum install mysql-server

systemctl restart mysqld


Step4: Create initial database

mysql -uroot -p
password
mysql> create database zabbix character set utf8mb4 collate utf8mb4_bin;
mysql> create user zabbix@Zabbix_core_ip identified by 'password';
mysql> grant all privileges on zabbix.* to zabbix@zabbix_core_ip;
mysql> set global log_bin_trust_function_creators = 1;
mysql> quit;


Step5:Import initial schema and data. You will be prompted to enter your newly created password.

zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix


Step6: Disable log_bin_trust_function_creators option after importing database schema.

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



On Zabbix Proxy Server

Step1: Install Zabbix repository

rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-latest-6.0.el8.noarch.rpm

dnf clean all


Step2: Install Zabbix proxy

dnf install zabbix-proxy-mysql zabbix-sql-scripts zabbix-selinux-policy zabbix-agent


Step3: Create initial database

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


Step4: Import initial schema and data

cat /usr/share/zabbix-sql-scripts/mysql/proxy.sql | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix_proxy

Disable log_bin_trust_function_creators option after importing database schema.

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


Step5: Configure the database and Zabbix core server details in Zabbix proxy conf file:

Edit file /etc/zabbix/zabbix_proxy.conf

Server=zabbix_core_ip

Hostname=zabbix proxy  --------> It should be same as you configured in Zabbix(proxy details)

DBPassword=password


Now you can access the UI

Zabbix_core_server_ip/zabbix


Note: Required Port:10050,10051,3306 should be enable in firewall and selinux should be disabled.

API & API in Zabbix

-
API (Application programming interface):   An API is a set of rules and protocols that allows one software application to interact with another. It defines the methods and data formats that applications can use to request and exchange information. APIs are typically used for both retrieving data from a service (like fetching information from a database or another web service) and sending data to a service (like submitting a form or updating information). Zabbix API: The Zabbix API is a powerful tool that allows you to interact programmatically with the Zabbix monitoring system. It provides endpoints for various operations such as managing hosts, items, triggers, and more. The Zabbix API is a JSON-RPC-based interface provided by Zabbix for programmatically interacting with and managing the Zabbix monitoring system. ### Key Features - **Automate Tasks**: Create, update, or delete objects like hosts, items, and triggers. - **Query Data**: Retrieve monitoring data, configuration detail...
