本文介绍了使用curl命令在Elasticsearch中创建索引的方法，包括如何通过内网IP进行操作，并提供了创建、验证及删除索引的具体示例。

　　启动es，请移步

Elasticsearch的前后台运行与停止(tar包方式）

Elasticsearch的前后台运行与停止(rpm包方式）

　　创建索引库，我这里命名为zhouls

[hadoop@djt002 elasticsearch-2.4.3]$ curl -XPUT 'http://192.168.80.200:9200/zhouls'
{"acknowledged":true}[hadoop@djt002 elasticsearch-2.4.3]$

这里，是跟之前的elasticsearch.yml修改对应起来的。

　　我们可以验证下，输入localhost或者127.0.0.1都会出现无法连接，不信你尝试。

[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]$

为了方便，更改为0.0.0.0

　　然后，重启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'
{"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://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]$

报这个错误，是正常的，因为，你重复创建索引库。根据经验之谈，一般用内网ip。如我的192.168.80.200。建议指定内网ip

服务器一般都会有多种ip地址，
本地回环地址:127.0.0.1
内网地址:192.168.80.200
外网地址:10.29.0.2
在这里0.0.0.0 表示可以通过上面所有ip都可以访问

　　以上是，Elasticsearch之curl创建索引库的方式1，以下是，Elasticsearch之curl创建索引库的方式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]$

　　测试完，及时删除。

[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'
{"acknowledged":true}[hadoop@djt002 elasticsearch-2.4.3]$
