A Beginner’s Guide to Installing and Configuring Zabbix on CentOS

Before you begin the installation process, ensure that you have the following prerequisites in place:

  1. A CentOS server (preferably the latest version) with root access or a user with sudo privileges.
  2. A LAMP stack (Linux, Apache, MySQL, and PHP) is installed and configured on your server.

Now, let’s get started with the installation and configuration process.

Step 1: Update System Packages
First, update your CentOS server’s packages to their latest versions:

sudo yum update

Step 2: Install Required Packages
Next, install the necessary packages for Zabbix:

sudo yum install -y epel-release
sudo yum install -y zabbix-server-mysql zabbix-web-mysql zabbix-agent

During the installation, you’ll be prompted to install the required MySQL server and PHP modules. Confirm the installation when prompted.

Step 3: Configure MySQL for Zabbix
Create a new database and user for Zabbix in MySQL:

sudo mysql -u root -p
CREATE DATABASE zabbixdb character set utf8 collate utf8_bin;
CREATE USER 'zabbixuser'@'localhost' IDENTIFIED BY 'your_password';
GRANT ALL PRIVILEGES ON zabbixdb.* TO 'zabbixuser'@'localhost';

Replace 'your_password' with a strong password of your choice.

Step 4: Import Initial Schema and Data
Import the initial Zabbix schema and data into the MySQL database:

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | sudo mysql -u zabbixuser -p zabbixdb

You’ll be prompted to enter the password for the Zabbix MySQL user.

Step 5: Configure Zabbix Server
Open the Zabbix server configuration file in a text editor:

sudo nano /etc/zabbix/zabbix_server.conf

Locate the DBPassword parameter and replace your_password with the password, you set for the Zabbix MySQL user in Step 3.

Save the file and exit the text editor.

Step 6: Configure PHP for Zabbix Web Interface
Edit the PHP configuration file for the Zabbix web interface:

sudo nano /etc/httpd/conf.d/zabbix.conf

Locate the line that starts with php_value date.timezone and set the appropriate timezone for your location. For example:

php_value date.timezone America/New_York

Save the file and exit the text editor.

Step 7: Start Zabbix Services
Start the Zabbix server and agent services:

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

Step 8: Access Zabbix Web Interface
