Elasticsearch之curl创建索引库

　　关于curl的介绍，请移步

　　启动es，请移步

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\'
