Elasticsearch is an open-source, full-text search and analytics engine. It is used to index and store large volumes of data, and to perform complex search queries on this data. This tutorial will guide you through the steps to install Elasticsearch on Elementary OS Latest.
Before getting started, you will need to have the following:
The first step is to update your system repositories to ensure that you are installing Elasticsearch from the latest available version. Open a terminal and type the following command:
sudo apt update
Elasticsearch requires Java to run. If you don't have Java installed on your system, you can install it by typing the following command:
sudo apt-get install openjdk-11-jdk
Verify the installation by checking the version by typing in the following:
java -version
Go to the Elasticsearch download page (https://www.elastic.co/downloads/elasticsearch) and download the Elasticsearch package for your platform. To download the .tar.gz file run the command as github host:
wget https://github.com/elastic/elasticsearch/archive/PR_NUMBER.zip
Create a directory where you will install Elasticsearch:
sudo mkdir /usr/share/elasticsearch
Extract the downloaded file to the created directory:
sudo unzip PR_NUMBER.zip -d /usr/share/elasticsearch
Rename the extracted directory:
sudo mv /usr/share/elasticsearch/elasticsearch-PR_NUMBER /usr/share/elasticsearch/elasticsearch
By default, Elasticsearch is not configured to run as a service, we will configure Elasticseatch running as a systemd service.
Create a new file with the name /etc/systemd/system/elasticsearch.service:
sudo nano /etc/systemd/system/elasticsearch.service
Paste the following content into the file:
[Unit]
Description=Elasticsearch
After=network.target
[Service]
User=root
Group=root
LimitNOFILE=65535
Environment=JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/
Environment=ES_HOME=/usr/share/elasticsearch/
ExecStartPre=/usr/share/elasticsearch/bin/elasticsearch-systemd-pre-exec
ExecStart=/usr/share/elasticsearch/bin/elasticsearch
Restart=always
SyslogIdentifier=elasticsearch
[Install]
WantedBy=multi-user.target
Save and close the file.
Reload systemd:
sudo systemctl daemon-reload
Then enable the Elasticsearch service:
sudo systemctl enable elasticsearch
You can now start Elasticsearch by running:
sudo systemctl start elasticsearch
Check the Elasticsearch status:
sudo systemctl status elasticsearch
You've successfully installed Elasticsearch on Elementary OS Latest. Now, you can start working with Elasticsearch!
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
