Let’s get started and build your Zabbix Server on Ubuntu 22.04 easily.

Step 1: Install MariaDB

sudo apt update
sudo apt install mariadb-server -y
sudo mysql_secure_installation

When asked:
• Root password? ➜ Enter
• Set root password? ➜ Y
• Remove anonymous users? ➜ Y
• Disallow remote root login? ➜ Y
• Remove test database? ➜ Y
• Reload privilege tables? ➜ Y

Step 2: Create database for Zabbix

Query the mysql shell with the root user created above (Abc#1234)
sudo mysql -u root -p

Run each command in turn to create the zabbix database and create a zabbix user to administer this database, granting full rights to this user

CREATE DATABASE zabbix CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;
CREATE USER zabbix@localhost IDENTIFIED BY ‘Abc@1234’;
GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@localhost;
FLUSH PRIVILEGES;
EXIT;

Step 3: Install Zabbix

Install from repo
wget https://repo.zabbix.com/zabbix/7.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_7.0-1+ubuntu22.04_all.deb

sudo dpkg -i zabbix-release_7.0-1+ubuntu22.04_all.deb

sudo apt update

Step 4: Install Zabbix server + frontend + agent

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

Step 5: Import database schema for Zabbix

zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql -u zabbix -p zabbix

Enter the password of the zabbix user created above

Step 6: Configure the Zabbix Server file

sudo nano /etc/zabbix/zabbix_server.conf

Find and edit the line
DBPassword=Abc@1234 (password of zabbix user)

Check and configure PHP (if needed)

sudo nano /etc/zabbix/apache.conf

Check the timezone:
php_value date.timezone Asia/Ho_Chi_Minh
Check if this line is not found  Do not change anything in the apache.conf file
sudo systemctl restart apache2

Step 7: Enable the web UI access service

sudo systemctl restart zabbix-server zabbix-agent
sudo systemctl enable zabbix-server zabbix-agent apache2 mariadb
