Deploying an Elasticsearch cluster via SaltStack
Here is a short guide covering the steps I followed in order to deploy an ElasticSearch cluster using SaltStack to manage configuration.
Prerequisites
For the purposes of testing, I will be using a bunch of locally-installed virtualmachines. Specifically, we'll have:
- A machine running salt master
- Three elasticsearch nodes
Creating the VMs
To create the machines, I just installed a bare-bones wheezy image (under KVM) and cloned it four times:
virt-clone -o TemplateWheezy -n es-cluster-salt-master -f /mnt/virtualmachines/es-cluster-salt-master.img -m '52:54:00:ee:55:f0'
for id in 01 02 03; do
virt-clone -o TemplateWheezy -n es-cluster-node-"$id ...Importing Apache logs in ElasticSearch
I needed some way to visualize and analyze logs from webservers.
So, I decided to use the "elasticsearch stack" for that:
Setting up ElasticSearch
Just download, untar and launch:
wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.1.1.tar.gz tar xzvf elasticsearch-1.1.1.tar.gz cd elasticsearch-1.1.1 ./bin/elasticsearch
Check if everything is ok:
http localhost:9200
Importing logs to ElasticSearch
I used LogStash to import the logs from file to ElasticSearch. That required a bit of configuration.
First, download & unpack logstash:
wget https://download.elasticsearch.org/logstash/logstash/logstash-1.4.0 ...
