Job for elasticsearch.service failed because the control process exited with error code

I have newly installed the elastic search-7.4.2-x86_64.rpm with rmp from the link
https://www.elastic.co/guide/en/elasticsearch/reference/7.6/rpm.html

But when i start the service it gives the below error .
sudo systemctl start elasticsearch.service

Job for elasticsearch.service failed because the control process exited with error code. See "systemctl status elasticsearch.service" and "journalctl -xe" for details.

In journalctl it giving the below error :slight_smile:

Welcome to our community! :smiley:

Please check the Elasticsearch logs for more information, you can use journalctl -u elasticsearch.service for that, or look at the log file in `/var/log/elasticsearch/.

Please also format your code/logs/config using the </> button, or markdown style back ticks. It helps to make things easy to read which helps us help you :slight_smile:

Thank you for your response .

The issue was resolved and it was due to /tmp that was non exec .

I have make the /tmp exec and it start working.
