Installation of Moloch

  • Author : Miroslav Kohútik
  • Tested version : 1.7.0
  • Operating system : Ubuntu 16.04

Installation of Moloch is no trivial matter, that is why we have prepared this guide on how to set up the system in cloud environment.

Setup before installation

Before installing Moloch itself, you need to install the Elasticsearch database and make the following changes in configuration of the operating system.

Add Java repository

sudo add-apt-repository ppa:webupd8team/java 

Perform an update of the list of packages and packages themselves to the latest versions

sudo apt-get update -y && sudo apt-get upgrade -y

Download and install the public GPG signing key

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -

Add Elastic Repository

echo "deb https://artifacts.elastic.co/packages/5.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-5.x.list

Perform another package update

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

Clean-up (Optional)

sudo apt-get autoremove

Disable swap

sudo swapoff -a
sudo nano /etc/fstab

Edit fstab – comment out the following:

#/dev/mapper/logs--vg-swap_1 none     swap   sw      0     0

or

#/dev/mapper/user--vg-swap_1 none     swap   sw      0     0

Install Java 8

sudo apt-get install oracle-java8-installer

Install Elasticsearch

sudo apt-get install elasticsearch

sudo apt-get install wget curl libpcre3-dev uuid-dev libmagic-dev pkg-config g++ flex bison zlib1g-dev libffi-dev gettext libgeoip-dev make libjson-perl libbz2-dev libwww-perl libpng-dev xz-utils libffi-dev

wget https://files.molo.ch/builds/ubuntu-16.04/moloch_1.7.0-1_amd64.deb

Note: when asked whether or not to install Elasticsearch choose no, since you have already installed Elasticsearch earlier and this script offers only the demo version.

sudo dpkg -i moloch_1.7.0-1_amd64.deb

Install dependencies (If the previous step halts due to errors)

sudo apt-get -f install
