Directory layout of RPM
The RPM places config files, logs, and the data directory in the appropriate locations for an RPM-based system:
Configure network host
sed -i 's/#network.host: 192.168.0.1/network.host: 172.17.20.100/g' /etc/elasticsearch/elasticsearch.yml
start elasticsearch
systemctl restart elasticsearch.service
Check Elasticsearch Status
curl -XGET 'http://172.17.20.100:9200'
Check Health of Cluster
curl -XGET 'http://172.17.20.100:9200/_cluster/health?pretty=true'
Get Indica details
curl -XGET '172.17.20.100:9200/_cat/indices?v'
create an index named "linuxtopic" and then list all the indexes again:
curl -XPUT '172.17.20.100:9200/linuxtopic?pretty'
curl '172.17.20.100:9200/_cat/indices?v'
Delete an index named "linuxtopic"
curl -XDELETE '172.17.20.100:9200/linuxtopic?pretty'
