Install Logstash on Linux or Mac OS X

Logstash is a tool for managing events and logs.w

Download package

We need to download a distribution package. So go to the elastic site and choose logstash in products.

All products

Or simply follow this link Download logstash page

Manual Installation

Now we need to unarchive a tar.gz. So go to download folder and enter the command in terminal :

tar -xzvf /home/lytvynov/Téléchargements/logstash-6.2.4.tar.gz

Now we have unarchived logstash. To start a logstash and test it type :

cd logstash-6.2.4
bin/logstash -e “input { stdin { } } output { stdout {} }”

You should see something like that

If you don’t pass -e “…” option you’ll see the error message

Pipeline error

Logstash needs to know input/output formats and for this, it waits for pipeline file.

Simple pipeline

You can find more details about pipelines here. I leave a simple pipeline with input in JSON format and output on rubydebug just to give an idea how it works.

input {
 stdin {
 codec => json
 }
}
output {
 stdout {
 codec => rubydebug
 }
}

Add it to your logstash folder :

touch path_to_logstash/config/pipelines/pipeline.conf

To run logstash with this pipeline enter a command :

bin/logstash -f config/pipelines/pipeline.conf

Install Logstash with Homebrew on Mac OS X

Mac os x users should be familiar with Homebrew (brew). To install it run this command in terminal :

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Use brew command in terminal to install Logstash :

brew update
brew install logstash

To run Logstash :

logstash -e “input { stdin { } } output { stdout {} }”

Congratulations !

Now you can work with Logstash on your localhost !
