Elasticsearch 7.6.2 service not starting on CentOS 7.x with cPanel installed on it

Question

I have installed elasticsearch version 7.2.6 on CentOS 7.x with cPanel on it. However, after installing it, elasticsearch service is not running. Here is the screen capture of the error. I have already tried. https://support.cpanel.net/hc/en-us/articles/360055446413-How-To-Install-Run-Elasticsearch but the issue is not resolved. Any help will be appreciated.

I have set my IP address in network.host

Answer 1

You probably have data from an older ES install. If you're installing a new version and want to keep your older data, you need to go through the upgrade path.

otherwise, if you don't care about your older data and simply want to install the newer version, simply delete the content of /var/lib/elasticsearch and install the new version.
