Install Zabbix on Ubuntu Server 16.04 LTS – Complete Guide

In this Article, you will learn how to install Zabbix on Ubuntu Server 16.04 LTS. Zabbix is an open source monitoring software for networks, operating systems, and applications, created in Latvia by Alexei Vladishev. It is designed to monitor and track the status of various network services, servers, and other network hardware.

I will take you through the whole process, step-by-step. To install Zabbix, you first need to install Ubuntu Server 16.04 LTS, I won’t go over this in this tutorial.

Step 1 – Updating your System

First things first, make sure your Ubuntu is up to date.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade -y

After this is done, clean up your System.

sudo apt-get autoremove -y

Step 2 – Installing prerequisites to be able to Install Zabbix

Now you need to install a long list of necessary software to be able to Install Zabbix. Set and remember the MySQL Password that you will set during this process.

sudo apt-get install dnsutils htop make gcc libc6-dev libmysqlclient-dev libcurl4-openssl-dev libssh2-1-dev libsnmp-dev libiksemel-dev mysql-server libopenipmi-dev fping php7.0-gd snmp libsnmp-base openjdk-8-jdk unixodbc unixodbc-dev libxml2 libxml2-dev snmp-mibs-downloader snmpd snmptrapd snmptt python-pywbem php7.0-ldap traceroute ipmitool libldap2-dev php7.0-bcmath php7.0-mbstring php7.0-xml ttf-dejavu-core -y

Copy this text (just double-click in front of apt to mark the whole line) and paste it in your terminal.

Step 3 – Adding the Zabbix Repository

As of now, the newest Zabbix Version is 3.4 – Which is what we are going to install. You can check for the newest Versions here and adjust accordingly. You also have the Option to install the LTS Version of Zabbix.

sudo wget http://repo.zabbix.com/zabbix/3.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_3.4-1+xenial_all.deb
sudo dpkg -i zabbix-release_3.4-1+xenial_all.deb
sudo apt-get update

Step 4 – Time to Install Zabbix

Time to run the Zabbix Installation.

sudo apt-get install zabbix-server-mysql zabbix-frontend-php zabbix-agent zabbix-get zabbix-sender zabbix-java-gateway

Step 5 – Configuring the MySQL DB

We will do a few modifications to our MySQL DB.

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

Below the [mysqld] tag, paste the following lines, be careful not to overwrite any of the existing lines.

#MySQL Customization
innodb_log_file_size = 512M
innodb_doublewrite = 0
innodb_flush_log_at_trx_commit = 2
innodb_buffer_pool_size = 1G
innodb_support_xa = No

Make sure that the innodb_buffer_pool_size is not exceeding your actual RAM, otherwise MySQL won’t start.

Leave Nano with CTRL + X and confirm to save with Y.

Let’s restart MySQL.

sudo systemctl restart mysql

Step 6 – Creating the Zabbix Database

While creating the Database, you will be prompted for your MySQL Password that you have set earlier.

sudo mysql -u root -p -e "create database zabbix character set utf8 collate utf8_bin"
sudo mysql -u root -p -e "grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix'"
sudo zcat /usr/share/doc/zabbix-server-mysql/create.sql.gz | mysql -uzabbix -pzabbix zabbix

Step 7 – Modifying the Zabbix Config

Open the Zabbix Config.

sudo nano /etc/zabbix/zabbix_server.conf

Find the following entries (using CTRL+W) and change them accordingly. If some of them have a # in front, remove it. The Values below are recommended Settings for a fresh installation.

DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
 
StartIPMIPollers=5
StartPollersUnreachable=5
StartPingers=10
StartVMwareCollectors=5

Step 8 – Enabling Autostart for Zabbix

Now, of course, we want Zabbix to automatically start with the System.

sudo systemctl enable zabbix-server.service

And also the Agent.

sudo systemctl enable zabbix-agent.service

Let’s start Zabbix and check if it’s running.

sudo systemctl start zabbix-server
sudo systemctl status zabbix-server

If all goes well, you’ll see something along those lines. Leave this page by pressing Q.

Step 11 – Installing NTP

Let’s install NTP.

sudo apt-get install ntp -y

If you want to modify the Default Time Server, you can do it by modifying the config file.

sudo nano /etc/ntp.conf
