Zabbix is a web-based open source monitoring tool for monitoring various IT components. This includes network devices such as servers, virtual machines, and applications. It offers a wide variety of monitoring metrics such as network usage, CPU usage, and disk usage. This makes troubleshooting easier if the system behaves abnormally. You can visualize the key performance indicators in the form of graphs, screens, maps and overviews.
In this guide, we are going to show you how to install it Zabbix server 5.0 on Ubuntu 04/20 LTS.
Before starting, make sure you have a running Ubuntu 20.04 instance with sudo permissions. Also, make sure you are connected to a stable internet connection.
Step 1: install and set up Apache
In this step we install the Apache web server. First, update all Ubuntu repository lists and install Apache packages by running the following command:
$ sudo apt update
now Install Apache with the following command:
$ sudo apt install apache2
The Apache service is started by default after installation. If not started, run the following command to start Apache2.
$ sudo systemctl start apache2
to Activate Apache2 Enter the following at boot:
$ sudo systemctl enable apache2
Step 2: Install PHP and related modules
The front end of Zabbix is written in PHP and therefore we have to install PHP. Ubuntu already provides PHP 7.4 by default in its repositories. This is what we’re going to use for this guide.
To install PHP packages use the following apt command:
$ sudo apt install php php-mbstring php-gd php-xml php-bcmath php-ldap php-mysql
You can check the installed PHP version with the following command:
$ php -v
Once the installation is complete, go to the PHP configuration directory and edit the /etc/php/7.4/apache2/php.ini File. Change the parameters as shown and make sure you set the correct time zone according to your locale.
$ sudo vim /etc/php/7.4/apache2/php.ini
Restart the Apache service for the changes to take effect
$ sudo systemctl restart apache2
Step 3: Install MariaDB database server
Next, we’ll install the MariaDB database as our preferred database server for storing user data and storing other metrics.
Install MariaDB Server packages by running the following command:
$ sudo apt install mariadb-server
After the installation, make sure to harden your database server with the following command:
$ sudo mysql_secure_installation
Start by setting the root password.
Then type ‘AND‘for all remaining prompts:
Step 4: create the Zabbix user and database
Next we will create a database user for the Zabbix server. You need to log into the MariaDB instance first:
$ sudo mysql -u root -p
Create a Zabbix user and database as shown and give the user all permissions as follows:
CREATE DATABASE zabbix_db character set utf8 collate utf8_bin; CREATE USER 'zabbix_user'@'localhost' IDENTIFIED BY '[email protected]'; GRANT ALL PRIVILEGES ON zabbix_db.* TO 'zabbix_user'@'localhost' WITH GRANT OPTION; FLUSH PRIVILEGES;
Step 5: Activate the Zabbix repository
To add the Zabbix repository to your system, first Download the Zabbix Share the Debian package with the wget command.
$ wget https://repo.zabbix.com/zabbix/5.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.0-1+focal_all.deb
We use Zabbix 5.01 version This is the case at the latest when this manual is written.
Then enter the following to activate the Zabbix repository:
$ sudo dpkg -i zabbix-release_5.0-1+focal_all.deb
To synchronize the newly added repository with the system, update the package lists
$ sudo apt update
Step 6: Install the Zabbix server on Ubuntu 20.04
To install the Zabbix server we install the zabbix-server-mysql Package that provides MySQL support, the zabbix-frontend-php Package that is next to a web interface for the server zabbix-agent for shipping metrics and the zabbix-apache-conf Package for Apache.
$ sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-agent zabbix-apache-conf
Step 7: configure the Zabbix server
With Zabbix installed, some additional tweaking is required. The configuration file is located under /etc/zabbix/zabbix_server.conf Path. So open the file.
$ sudo vim /etc/zabbix/zabbix_server.conf
Update your database configurations according to your database user settings
DBHost=localhost DBName=zabbix_db DBUser=zabbix_user [email protected]
Then load the standard schema of the Zabbix database.
$ cd /usr/share/doc/zabbix-server-mysql $ zcat create.sql.gz | mysql -u zabbix_user -p zabbix_db
You’ll need to provide your password so go ahead and enter it.
Now enable the Zabbix service to start at system startup and restart the service to apply the new settings.
$ sudo systemctl enable zabbix-server
$ sudo systemctl restart zabbix-server
You can check the status of Zabbix with the following command:
$ sudo systemctl status zabbix-server
Zabbix also creates its own Apache configuration file /etc/zabbix/apache.conf and creates a link to the Apache configuration directory. Use the following command to restart the Apache services.
$ sudo systemctl restart apache2
Also make sure Apache is running:
$ sudo systemctl status apache2
Your system is now ready for the Zabbix installation.
Step 6: configure the firewall
If you are behind a firewall, you have to allow the Zabbix ports 10050 and 10051 as well as HTTP. Run the following commands to allow the ports:
$ sudo ufw allow 80/tcp
$ sudo ufw allow 10050/tcp
$ sudo ufw 10051
Then reload your firewall service for the changes made above to take effect:
$ sudo ufw reload
Step 7: Complete the Zabbix installation in a browser
We’re all set now. All that remains is to complete the installation in a web browser. So start your browser and navigate to the address shown:
http: // server-ip / zabbix
You will receive a welcome page shown below. Just click Next to go to the next step.
Check whether all requirements have been met by the server and click the Next Step button.
In the next step, enter the database credentials you provided in step 4 when you created a database for Zabbix and click the Next Step button.
For the Zabbix server details, enter your server host name and IP address and then click the “Next Step” button again.
You will get a pre-installation summary as shown. Make sure all configuration parameters are correct, then click the Next Step button.
After the installation has completed successfully you should see the following screen:
Click the Finish button. You will be redirected to the Zabbix front end login page shown below:
Sign in with the following default credentials:
After successfully signing in, you will see the Zabbix dashboard as shown below:
And that’s it! You can now start adding your hosts to the monitoring server to keep an eye on their performance. In this guide, we have shown you how to install the Zabbix server on the Ubuntu 20.04 system.
