Installing Zabbix on Ubuntu 20.04

Zabbix is an open-source monitoring software that allows you to track the performance and availability of various network services, servers, and other network equipment. Here, we provide step-by-step instructions for installing Zabbix on Ubuntu 20.04.

1. Update your system's package index by running the command:

   sudo apt update

2. Now, we need to install a few packages, including Apache, MariaDB, PHP, and other necessary dependencies. Run the following command:

   sudo apt install apache2 mariadb-server php php-mysql php-gd php-xml php-bcmath php-mbstring php-ldap php-xmlwriter

3. Next, we'll secure the MariaDB installation. Run the following command and follow the prompts to set a password for the MariaDB root user:

   sudo mysql_secure_installation

4. Create a new database for Zabbix using the following commands:

   sudo mysql -u root -p

   CREATE DATABASE zabbix character set utf8 collate utf8_bin;

   CREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'your_password_here';

   GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'localhost' WITH GRANT OPTION;

   FLUSH PRIVILEGES;

   EXIT;

5. Now, let's download and import the Zabbix database schema:

   wget https://repo.zabbix.com/zabbix/5.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.2-1+ubuntu20.04_all.deb

   sudo dpkg -i zabbix-release_5.2-1+ubuntu20.04_all.deb

   sudo apt update

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

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

6. Configure the Zabbix server by editing the configuration file:

   sudo nano /etc/zabbix/zabbix_server.conf

   Update the following parameters:

   DBPassword=your_password_here

   Save the changes and close the file.
7. Next, we need to configure the PHP settings for Zabbix:

   sudo nano /etc/zabbix/apache.conf

   Uncomment and update the following line:

   php_value date.timezone 

   Save and close the file.
8. Restart the Apache and Zabbix services to apply the changes:

   sudo systemctl restart apache2

   sudo systemctl restart zabbix-server

   sudo systemctl enable zabbix-server

   sudo systemctl enable zabbix-agent

9. Finally, access the Zabbix web interface by opening your web browser and entering your server's IP or domain name followed by "/zabbix" (e.g., http://your_server_ip/zabbix). Follow the on-screen instructions to complete the installation. The default login credentials are:

   Username: Admin

   Password: zabbix

   Be sure to change the password after login.

Congratulations! You have successfully installed Zabbix on Ubuntu 20.04. You can now start monitoring your infrastructure using this powerful open-source monitoring solution.
