            sudo mysql -u root -p
        
    

        
            CREATE DATABASE zabbixdb character set utf8 collate utf8_bin;
            CREATE USER 'zabbixuser'@'localhost' IDENTIFIED BY 'password';
            GRANT ALL PRIVILEGES ON zabbixdb.* TO 'zabbixuser'@'localhost';
            FLUSH PRIVILEGES;
            EXIT;
        
    

        
            wget https://repo.zabbix.com/zabbix/5.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.4-1%2Bfocal_all.deb
            sudo dpkg -i zabbix-release_5.4-1+focal_all.deb
            sudo apt update
        
    

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

Open the Zabbix server configuration file:

        
            sudo nano /etc/zabbix/zabbix_server.conf
        
    

Make the following changes:

        
            DBHost=localhost
            DBName=zabbixdb
            DBUser=zabbixuser
            DBPassword=password
            ... 
        
    

Open the PHP configuration file:

        
            sudo nano /etc/zabbix/apache.conf
        
    

Uncomment the date.timezone entry and set your timezone:

        
            php_value date.timezone your_timezone
        
    

Create a new Apache virtual host configuration file:

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

Add the following content to the file:

        
            
                ServerName your_domain_or_IP
                DocumentRoot /usr/share/zabbix
                CustomLog /var/log/apache2/zabbix_access.log combined
                ErrorLog /var/log/apache2/zabbix_error.log
                
                    Options FollowSymLinks
                    AllowOverride All
                    Require all granted
                
            
        
    

Enable the virtual host:

        
            sudo a2ensite zabbix.conf
            sudo a2enmod rewrite
        
    

Restart Apache:

        
            sudo systemctl restart apache2
        
    

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

Edit the Zabbix PHP configuration file:

        
            sudo nano /etc/zabbix/zabbix.conf.php
        
    

Update the database settings:

        
            $DB['TYPE'] = 'MYSQL';
            $DB['SERVER'] = 'localhost';
            $DB['PORT'] = '0';
            $DB['DATABASE'] = 'zabbixdb';
            $DB['USER'] = 'zabbixuser';
            $DB['PASSWORD'] = 'password';
            ...
