Step 1: Installing and Configuring Apache2:

Step 1.1 — Installing Apache

Open terminal and run:

sudo apt update

Install the Apache web server:

sudo apt install apache2 -y

Allow incoming connections on the default Apache port through the firewall:

sudo ufw allow 'Apache'

Start the Apache web server:

sudo systemctl start apache2

Enables Apache to start automatically on system boot:

sudo systemctl enable apache2

Now verify if apache2 is working or not, so let’s try accessing its default webpage using our IP address:

Now let’s navigate our browser’s URL to run http://[IP Address]. In my case it’s http://192.168.50.10:

Step 1.2 — Configuring Apache to host Zabbix:

Opens the zabbix.conf file for editing using the nano text editor:

sudo nano /etc/apache2/sites-available/zabbix.conf

Place the following code in the zabbix.conf file:

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    ServerName zabbix
    ServerAlias www.zabbix-server.com
    DocumentRoot /var/www/zabbix
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Enable the zabbix.conf site configuration file within Apache, allowing it to be served by the web server:

sudo a2ensite zabbix.conf

Disable the default site configuration file (000-default.conf). This command stops Apache from serving the default page if no other sites are enabled:

sudo a2dissite 000-default.conf

Check the Apache configuration files for syntax errors or potential issues. This command is used to validate the configuration before applying changes:

sudo apache2ctl configtest

Restart the Apache web server, applying any configuration changes made. This ensures that the new settings take effect without requiring a full system reboot.

sudo systemctl restart apache2

Step 2 — Installing and Setting Up MySQL

Step 2.1 — Installing MySQL

Update the local database of available packages from the software repositories:

sudo apt update

Install the MySQL server:

sudo apt install mysql-server -y

Start the MySQL service, allowing it to run:

sudo systemctl start mysql.service

Enable the MySQL service to start automatically on system boot, ensuring it starts up with the system:

sudo systemctl enable mysql.service

Initiate the MySQL command-line interface (CLI):

mysql -u root -p

Note: If you have not set up any root password, then just press Enter to continue.

Step 2.2 — Configuring MySQL Database:

Run the following MySQL commands to create a database, user, and password, granting the user all privileges on the ‘zabbix’ database. Additionally, allow non-superusers to create functions, enabling specific functionalities:

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

Step 3 — Installing and Configuring Zabbix 6.0:

Step 3.1 — Install Zabbix repository:

Download repository package from the Zabbix official repository:

wget https://repo.zabbix.com/zabbix/6.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.0-4+ubuntu22.04_all.deb

Install the Zabbix repository package:

sudo dpkg -i zabbix-release_6.0-4+ubuntu22.04_all.deb

Update packages:

sudo apt update

Install Zabbix server, frontend, agent:

sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent -y

Step 3.2 — Setting up Zabbix:

On Zabbix server host import initial schema and data. You will be prompted to enter your newly created password (‘password’):

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

Note: After entering your newly created password, the terminal will not show any result for 4 to 5 minutes, so wait patiently.

Disable log_bin_trust_function_creators option after importing database schema:

sudo mysql -uroot -p
set global log_bin_trust_function_creators = 0;
quit;

Add the password that you have setup in zabbix_server.conf file:

sudo nano /etc/zabbix/zabbix_server.conf

DBPassword=password

Restart the zabbix-server, zabbix-agent, and apache2 services:

systemctl restart zabbix-server zabbix-agent apache2

Enable zabbix-server, zabbix-agent, and apache2 services to start automatically on system boot : systemctl enable zabbix-server zabbix-agent apache2

Step 4—Mapping IP address to a hostname:

Step 4 .1— For Windows:

Navigate to CMD and run as administrator. In the terminal run:

notepad C:\Windows\System32\drivers\etc\hosts

At the bottom of the notepad file, type:
[IP Address] www.zabbix.com zabbix.com

So, for me it’s

192.168.50.10 www.zabbix-server.com zabbix-server.com

Save the file and exit.

Step 4.2—For Linux:

In the terminal run:

sudo nano /etc/hosts

At the bottom of the notepad file, type:
[IP Address] www.zabbix.com zabbix.com

So, for me it’s:

192.168.50.10 www.zabbix-server.com zabbix-server.com

Save the file and exit.

Step 4.3 — For Mac:

In the terminal run:

sudo nano /private/etc/hosts

at the bottom of the notepad file, type:
[IP Address] www.zabbix.com zabbix.com

So, for me it’s:

192.168.50.10 www.zabbix-server.com zabbix-server.com

Save the file and exit.

Step 5 — Configuring Zabbix Using the Web Interface:

In the browser’s URL, run http://zabbix-server.com/zabbix/setup.php.

Click “Next step,” and in “Configure DB connection,” verify all the current values are as required:

Note: If the current values are not up to the required values, then you can change that from /etc/php/8.1/apache2/php.ini

Click “Next step” and type the password you set up in your MySQL database:

Set your preferred Zabbix server name and time zone, then click Next step.

Check the pre-installed summary and then click Next step:

Congrats! You have successfully installed and configured Zabbix frontend:

Enter the login credentials as follows:

And we’re done!
