# Installation

The Elasticsearch tarball installation works on Linux systems. The tarball supports RHEL7, CentOS 7 and most other Linux distributions. You must install Java and set `JAVA_HOME` before starting the install.

1. Download the tarball and veridy the checksum. See the links in the compatible Elasticsearch version page
2. Extract the TAR file to a directory and change to that directory:

   ```
   tar -zxf elasticsearch-oss-7.8.0-linux-x86_64.tar.gz
   cd elasticsearch-7.8.0
   ```
3. Run Elasticsearch:

   ```
   ./bin/elasticsearch
   ```
