In this tutorial, we will show you how to install Zabbix on your Ubuntu 16.04 LTS server. 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 through the step by step installation of Zabbix in Ubuntu 16.04 LTS Xenial Xerus.
Install Zabbix on Ubuntu 16.04 LTS Xenial Xerus
Step 1. First, make sure that all your system packages are up-to-date by running these 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 16.04 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 php7.0-readline php7.0-curl php7.0-gd php7.0-mbstring libapache2-mod-php7.0 php7.0-mcrypt php7.0-bz2 php7.0-zip
Step 3. Installing Zabbix on Ubuntu 16.04.
The first thing to do is download and add the repository as shown below:
wget http://repo.zabbix.com/zabbix/3.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_3.2-1+xenial_all.deb dpkg -i zabbix-release_3.2-1+xenial_all.deb
After adding Zabbix apt repository in your system, Now update package lists and install Zabbix using commands:
apt-get update apt-get install zabbix-server-mysql zabbix-frontend-php
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_chosen_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 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 apache2 systemctl start zabbix-server
Step 7. Accessing Zabbix.
will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://your-domain.com/zabbix or 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 16.04 LTS system. For additional help or useful information, we recommend you to check the official Zabbix website.
