Spread the love

Zabbix is an open source software, where you can monitor your network and server infra. You can monitor your remote host with zabbix agent. In this article we will install and configure zabbix server and zabbix host on remote server and monitor it. We will use Ubuntu 16.04 for this project.

Install Apache, MysQl and PHP.

You will have to install LAMP in your Zabbix server. So first we will install Apache, Php and MysQl in zabbix server.

apt-get update

apt-get install apache2

apt-get install mysql-server

apt-get install php php-mbstring php-gd php-xml php-bcmath php-ldap php-mysql

After install php we will have to change and configure local timezon in php configuration file.

vim /etc/php/PHP_VERSION/apache2/php.ini

[Date]

; http://php.net/date.timezone

date.timezone = ‘Asia/Kolkata’

We will have to enable require APT repository to install Zabbix.

For Ubuntu 16.04 LTS:

wget http://repo.zabbix.com/zabbix/3.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_3.4-1+xenial_all.deb

dpkg -i zabbix-release_3.4-1+xenial_all.deb

Now we can install Zabbix server and Zabbix client on server host.

apt-get update

apt-get install zabbix-server-mysql zabbix-frontend-php

Now we will have to create Database schema for zabbix. Login to mysql and create and configure database and user for zabbix.

Mysql> create database zabbix;

Mysql> GRANT ALL on zabbix.* to zabbix@localhost IDENTIFIED BY ‘yourpassword’;

Mysql> FLUSH PRIVILEGES;

Mysql> quit;

Now we will have to import zabbix database schema in to our database.

cd /usr/share/doc/zabbix-server-mysql

zcat create.sql.gz | mysql -u root -p redhat [your mysql root password]

Now we have to define database username and password in zabbix server conf file.

vim /etc/zabbix/zabbix_server.conf

DBHost=localhost

DBName=zabbix

DBUser=zabbix

DBPassword=password

Restart apache server and zabbix service .

service apache2 restart

service zabbix-server restart

Now zabbx server installed and we have to open it from browse and configure it’s web interface.

http://your_zabbix_server_ip_address/zabbix/

Click next to configure Zabbix.

All require packages are showing ok. click next.

Enter database details which we have created above.

You need to define Host and port details.

It will show you summary of you have configured all settings.

Click next to install.
