Unable to start the elastic search in centos 7

[vikas2 (vikas)]

Hi Team am setting up Elasticsearch kibana instance to setup Wazuh . I am facing the below error while checking the status of service. Please let me know where I went wrong.

I have modified
/etc/elasticsearch/elasticsearch.yml and network.host to my Machine IP and change node.name to my system name.

[root@localhost vd]# systemctl status elasticsearch.service

Hey,

can you check the Elasticsearch logfiles or the journalctl logfiles, put them in pastebin and link them here?

See https://www.elastic.co/guide/en/elasticsearch/reference/7.6/starting-elasticsearch.html#start-es-deb-systemd
