How to install Elasticsearch on Fedora 28

Overview of the issue

I went to install Elasticsearch on a newly built Fedora 28 VM. For my first attempt, I tried to use the built-in repo as follows

sudo yum update
sudo yum install elasticsearch

However, when I started Elasticsearch, it failed to launch with the following error.

Could not find netty3-3.9.3 Java extension for this JVM

My first effort at resolution involved searching on-line for a solution. Some solutions recommend fixing Open JVM. However, it seemed to me to be a more straight-forward solution to just install the Oracle JVM. So, I removed Open JVM and installed Oracle JVM instead. This resolved the issue and Elasticsearch started normally.

Summary of my steps

Download the latest Oracle JVM from Oracle JVM Download

Install the repo with the following command.

sudo rpm -Uvh jdk-10.0.1_linux-x64_bin.rpm

I used the alternatives command to point to my java version.

alternatives --install /usr/bin/java java /usr/java/latest/jre/bin/java 200000

This installed the Oracle JVM.

Next, install Elasticsearch. This time I used a more recent Elasticsearch repo.

Import the GPG key

rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

Create /etc/yum.repos.d/elasticsearch.repo as below

[elasticsearch-6.x]
name=Elasticsearch repository for 6.x packages
baseurl=https://artifacts.elastic.co/packages/6.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

Run the install of Elasticsearch.

sudo yum install elasticsearch

Configure Elasticsearch to run at boot-time with the following instructions.

sudo systemctl daemon-reload
sudo systemctl enable elasticsearch

Start Elasticsearch with

sudo systemctl start elasticsearch

Finally, confirm that it has started correctly.

systemctl status elasticsearch
