In this tutorial, we will show you how to install Zabbix on your Ubuntu 18.04 LTS. For those of you who didn’t know, Zabbix is an open-source monitoring tool that is ideal for monitoring your cloud servers. Zabbix is very flexible, information can be retrieved using HTTP/SNMP or by installing a Zabbix agent on the machines to monitor, and allows a lot of customization.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘
sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Zabbix in Ubuntu 18.04 LTS Bionic Beaver.
- A server running one of the following operating systems: Ubuntu 18.04 LTS (Bionic Beaver)
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- SSH access to the server (or just open Terminal if you’re on a desktop).
non-root sudo useror access to the
root user. We recommend acting as a
non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
Install Zabbix on Ubuntu 18.04 LTS Bionic Beaver
Step 1. First, make sure that all your system packages are up-to-date by running the following
apt-get commands in the terminal.
sudo apt-get update sudo apt-get upgrade
Step 2. Install LAMP (Linux, Apache, MariaDB, and PHP) server.
A Ubuntu 18.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also, install all required PHP modules:
apt-get install php7.1-cli php7.1-gd php7.1-opcache php7.1-mysql php7.1-json php7.1-mcrypt php7.1-xml php7.1-curl
Step 3. Installing Zabbix on Ubuntu 18.04 LTS.
The latest version of Zabbix Server is 3.4 but the version available on Ubuntu repositories is 3.0. To install version 3.4, you need to add Zabbix repositories for this version:
wget http://repo.zabbix.com/zabbix/3.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_3.4-1+bionic_all.deb dpkg -i zabbix-release_3.4-1+bionic_all.deb
After adding Zabbix apt repository to your system, Now update package lists and install Zabbix using commands:
apt update apt install -y zabbix-server-mysql zabbix-frontend-php zabbix-agent
Step 4. Zabbix Configuration.
sudo nano /etc/zabbix/zabbix_server.conf
Adjust the following values and make a note of the password you’ve chosen. You’ll need it later too.
DBName=zabbixdb DBUser=zabbix DBPassword=your_password_here
Step 5. Configure MariaDB Database for Zabbix.
By default, MariaDB is not hardened. You can secure MariaDB using the
mysql_secure_installation script. you should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MySQL.
Configure it like this:
- Set root password? [Y/n] y - Remove anonymous users? [Y/n] y - Disallow root login remotely? [Y/n] y - Remove test database and access to it? [Y/n] y - Reload privilege tables now? [Y/n] y
Next, we will need to log in to the MariaDB console and create a database for Zabbix. Run the following command:
mysql -u root -p
This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for the Zabbix software:
create user 'zabbix'@'localhost' identified by 'your_chosen_password_here'; create database zabbixdb; grant all privileges on zabbixdb.* to 'zabbix'@'localhost'; flush privileges; exit;
After creating the Zabbix database and user we need to import the Zabbix initial database using the below commands:
cd /usr/share/doc/zabbix-server-mysql zcat create.sql.gz | mysql -u root -p zabbixdb
Step 6. Configure Apache web server for Zabbix.
First, we’ll move the Zabbix apache file from the package directory:
sudo cp /usr/share/doc/zabbix-frontend-php/examples/apache.conf /etc/apache2/conf-available/zabbix.conf sudo a2enconf zabbix.conf sudo a2enmod alias
We should adjust the PHP timezone as per Zabbix recommended settings:
### nano /etc/zabbix/apache.conf php_value max_execution_time 300 php_value memory_limit 128M php_value post_max_size 16M php_value upload_max_filesize 2M php_value max_input_time 300 php_value always_populate_raw_post_data -1 php_value date.timezone Europe/Rome
Restart the Apache and Zabbix service for the changes to take effect:
systemctl restart zabbix-server zabbix-agent apache2
Step 7. Accessing Zabbix.
will be available on HTTP port 80 by default. Open your favorite browser and navigate to
http://server-ip/zabbix and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
Congratulations! You have successfully installed Zabbix. Thanks for using this tutorial for installing Zabbix Monitoring Tool on your Ubuntu 18.04 Bionic Beaver LTS system. For additional help or useful information, we recommend you check the official Zabbix website.
