How to Setup PandoraFMS on ECS with CentOS 7

In this tutorial, we will learn how to install and configure PandoraFMS on an Alibaba Cloud Elastic Compute Service (ECS) instance with CentOS 7.

By Hitesh Jethva, Alibaba Cloud Community Blog author.

PandoraFMS can be installed in almost any operating systems like, Linux, Windows etc. Pandora FMS comes with built-in web console that allows you to operate and manage the monitoring system. Pandora FMS can be used with Docker Swarm, Nutanix, XEN, RHEV, HyperV and AWS/EC2.

In this tutorial, we will learn how to install and configure PandoraFMS on CentOS-7 server with an Alibaba Cloud Elastic Compute Service (ECS) instance.

Prerequisites

  • Two Alibaba Cloud Instance with CentOS 7 installed.
  • A static IP Address 172.20.10.11 is configured on Server instance and 172.20.10.12 is configured on Client instance.
  • A root password is set up on both instances.

Launch an Alibaba Cloud ECS Instance

Create a new ECS instance, choosing CentOS 7 as the operating system with at least 4GB RAM, and connect to your instance as the root user.

Once you are logged into your CentOS 7 instance, run the following command to update your base system with the latest available packages.

yum update -y

Getting Started

First, you will need to configure hostname and hostname resolution on both instances. So, each instance can communicate with each other by hostname.

On the server instance, setup hostname with the following command:

hostnamectl set-hostname node1.pandora.com

Next, configure hostname resolution by editing /etc/hosts file:

nano /etc/hosts

Add the following line:

172.20.10.11 node1.pandora.com
172.20.10.12 client.pandora.com

Save and close the file, when you are finished.

On the client instance, setup hostname with the following command:

hostnamectl set-hostname client.pandora.com

Configure hostname resolution by editing /etc/hosts file:

nano /etc/hosts

Add the following line:

172.20.10.11 node1.pandora.com
172.20.10.12 client.pandora.com

Save and close the file, when you are finished.

Next, you will need to disable Selinux on both instance. You can do this by editing /etc/selinux/config file:

nano /etc/selinux/config

Make the following changes:

SELINUX=disabled

Save and close the file. Then, restart both instances to apply the changes:

Install MariaDB Server

You will need to install MariaDB server to your server instance. You can install it by running the following command:

yum install mariadb-server -y

Once MariaDB is installed, start MariaDB service and enable it to start on boot time with the following command:

systemctl start mariadb
systemctl enable mariadb

Next, you will need to secure MariaDB installation. You can secure it by running the following script:

mysql_secure_installation

Answer all the questions as shown below:

    Enter current password for root (enter for none):
    Set root password? [Y/n]: N
    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

Install Pandora Console

Pandora console allows you to manage your monitoring system. By default, Pandora console package is not available in the CentOS 7 default repository. So, you will need to add Pandora FMS repository to your server instance.

You can add the repository by creating the following file on server instance:

nano /etc/yum.repos.d/pandorafms.repo

Add the following lines:

[artica_pandorafms]
name=CentOS6 - PandoraFMS official repo
baseurl=http://firefly.artica.es/centos7
gpgcheck=0
enabled=1

Save and close the file. Then, install Pandora console with the following command:

yum install pandorafms_console -y

Pandora FMS works with HTTP server. So, you will also need to start HTTP server with the following command:

systemctl start httpd

Install Pandora server with the following command:

yum install pandorafms_server

You will need to specify your database username and password in pandora_server.conf file:

nano /etc/pandora/pandora_server.conf

Make the following changes:

dbuser root
