This Is My elastic Search Confirguration
```auto
vim /etc/elasticsearch/elasticsearch.yml
#bootstrap.memory_lock: true
bootstrap.system_call_filter: false
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 74.208.203.170
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
discovery.seed_hosts: 74.208.203.170
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes: 3
#
# For more information, consult the zen discovery module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true

You need to provide the elasticsearch logs, also look at `/var/log/messages` for more information about why the service can't start.

It Is Showing me Error Like This
```auto
Job for elasticsearch.service failed because the control process exited with error code. S ee "systemctl status elasticsearch.service" and "journalctl -xe" for details.

You need to look the logs for the elasticsearch service, normally in `/var/log/elasticsearch/cluster-name.log`, you also need to look at the server logs, normally in `/var/log/messages`.
Try to start elasticsearch again and check the logs to get more recent information.
Also try to run `systemctl status elasticsearch -l` to get more verbose logs information.

Hi @mirza_muhriz
I think there is some confusion.

If you want help on this forum I suggest you figure out how to get to your logs
@leandrojmp Suggested one method
Or perhaps you should use the following as shown [here](https://www.elastic.co/guide/en/elasticsearch/reference/7.14/starting-elasticsearch.html)
`sudo journalctl --unit elasticsearch`
