創建索引庫，我這里命名為zhouls
[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPUT 'http://192.168.80.200:9200/zhouls'
{"acknowledged":true}[hadoop@djt002 elasticsearch-2.4.3]$
這里，是跟之前的elasticsearch.yml修改對應起來的。
我們可以驗證下，輸入localhost或者127.0.0.1都會出現無法連接，不信你嘗試。
[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPUT 'http://192.168.80.200:9200/zhouls'
{"acknowledged":true}[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPUT 'http://localhost:9200/zhouls'
curl: (7) couldn't connect to host
[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPUT 'http://127.0.0.1:9200/zhouls'
curl: (7) couldn't connect to host
[hadoop@djt002 elasticsearch-2.4.3]$
為了方便，更改為0.0.0.0
然后，重啟es
[hadoop@djt002 elasticsearch-2.4.3]$ jps
2811 Jps
2741 Elasticsearch
[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPUT 'http://localhost:9200/zhouls'
{"error":{"root_cause":[{"type":"index_already_exists_exception","reason":"already exists","index":"zhouls"}],"type":"index_already_exists_exception","reason":"already exists","index":"zhouls"},"status":400}[hadoop@djt002 elasticurl -XPUT 'http://127.0.0.1:9200/zhouls'

報這個錯誤，是正常的，因為，你重復創建索引庫。根據經驗之談，一般用內網ip。如我的192.168.80.200。建議指定內網ip
本地回環地址:127.0.0.1
內網地址:192.168.80.200
外網地址:10.29.0.2
在這里0.0.0.0 表示可以通過上面所有ip都可以訪問
以上是，Elasticsearch之curl創建索引庫的方式1，以下是，Elasticsearch之curl創建索引庫的方式2
[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPUT 'http://192.168.80.200:9200/zhouls'
{"error":{"root_cause":[{"type":"index_already_exists_exception","reason":"already exists","index":"zhouls"}],"type":"index_already_exists_exception","reason":"already exists","index":"zhouls"},"status":400}[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPOST 'http://192.168.80.200:9200/zhouls1'
{"acknowledged":true}[hadoop@djt002 elasticsearch-2.4.3]$
測試完，及時刪除。
[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPUT 'http://192.168.80.200:9200/zhouls'
{"error":{"root_cause":[{"type":"index_already_exists_exception","reason":"already exists","index":"zhouls"}],"type":"index_already_exists_exception","reason":"already exists","index":"zhouls"},"status":400}[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPOST 'http://192.168.80.200:9200/zhouls1'
{"acknowledged":true}[hadoop@djt002 elasticsearch-2.4.3]$ curl -XDELETE 'http://192.168.80.200:9200/zhouls1'
