How To Install and Configure Zabbix on AlmaLinux 8

Before you start to install Zabbix on AlmaLinux 8, you need some requirements.

Requirements

First, you need to log in to your server as a non-root user with sudo privileges and set up a basic firewall. To do this, you can follow our article the Initial Server Setup with AlmaLinux 8.

Then, you need to have the LAMP stack installed on your server. To dot his, you can check our article How To Install LAMP stack on AlmaLinux 8.

When you are done with these requirements, you can start to set up Zabbix on AlmaLinux 8.

Set up Zabbix on AlmaLinux 8

At this point, you need to visit the Zabbix Downloads Page and check the latest LTS version.

Then, you need to use the following commands to add the Zabbix repository on AlmaLinux 8:

$ sudo rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/8/x86_64/zabbix-release-5.0-1.el8.noarch.rpm
$ sudo dnf clean all

Next, you can use the following command to install the Zabbix on your server:

sudo dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-agent

When your installation is completed, you need to create a Zabbix database and user.

sudo mysql -u root -p

Next, from your MariaDB console run the following command to create a user, here we named it orca, you can choose your desired name. Remember to choose a strong password for your user.

CREATE USER orca@localhost IDENTIFIED BY 'password';

Create the database with the command below:

CREATE DATABASE zabbixdb character set utf8 collate utf8_bin;

Now grant all the privileges to the Zabbix database user:

GRANT ALL PRIVILEGES ON zabbixdb.* TO orca@localhost;

Flush the privileges and exit from your MariaDB console with the command below:

FLUSH PRIVILEGES;
EXIT;

Here you need to import the database schema with the following command:

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

You will be asked to enter your Zabbix user password.

Now you need to edit the Zabbix configuration file on AlmaLinux 8.

Open the file with your favorite text editor, here we use vi:

sudo vi /etc/zabbix/zabbix_server.conf

Find the line below and change them to your database settings:

DBHost=localhost
DBName=zabbixdb
DBUser=orca
DBPassword=password

You need to uncomment the DBHost and DBPassword lines by removing the “#” from the beginning of the lines.

When you are done, save and close the file.

Configure PHP-FPM on AlmaLinux 8

At this point, you need to make some configuration changes for the PHP-FPM service.

Open the file with the following command:

sudo vi /etc/php-fpm.d/www.conf

Find the lines below and make sure that they are like as shown below:

listen = /run/php-fpm/www.sock
 
user = apache
group = apache

listen.allowed_clients = 0.0.0.0
listen.owner = apache
listen.group = apache
listen.mode = 0660
pm = dynamic

When you are done, save and close the file.

Now you need to specify the timezone setting in the Zabbix configuration on AlmaLinux 8. To do this, run the command below:

sudo vi /etc/php-fpm.d/zabbix.conf

Find the line below and uncomment it by removing the “;” from the begging of the line and adding your timezone:

php_value[date.timezone] = America/New_York

When you are done, save and close the file.

Restart all the services to apply the changes:

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

To enable the services to start on boot, run the following command:

sudo systemctl enable zabbix-server zabbix-agent php-fpm

Configure SELinux and Firewall on AlmaLinux 8

At this point, you need to set SELinux to be allowed in order to access the Zabbix frontend on AlmaLinux 8. To do this, run the following command:

sudo sed -i 's/SELINUX=enforcing/SELINUX=permissive/g' /etc/selinux/config

Then, you need to allow traffic on ports 10050 and 10051 through the AlmaLinux firewall with the command below:

sudo firewall-cmd --add-port={10050,10051}/tcp --permanent

Reload the firewall to apply the changes:

sudo firewall-cmd --reload

Access Zabbix Web Interface

Here you access the Zabbix web interface on AlmaLinux 8 by typing your server’s IP address in your web browser followed by /Zabbix:

http://server-ip/zabbix

You will see the Zabbix welcome page just click on the next step.

In the next window, you will see the check for the pre-requisites. Make sure all the required PHP extensions are installed then click on the Next step button.

Then, you will see the configure DB connection page. Set your database details and click on the next step.
