给我:
{ "error": "IndexMissingException[[wham] missing]","status": 404}
我根据这些文件设置了所有内容:
> http://blog.comperiosearch.com/blog/2014/01/30/elasticsearch-indexing-sql-databases-the-easy-way/
> https://github.com/jprante/elasticsearch-river-jdbc
> https://github.com/jprante/elasticsearch-river-jdbc/wiki/Step-by-step-recipe-for-setting-up-the-river-with-PostgreSQL
> How to use Elastic Search on top of a pre-existing SQL Database?
最后一个是目前最有帮助的.
那很难过,我通过curl使用了两个不同的“设置”查询来创建我的河流:
curl -xpuT 'localhost:9200/_river/wham/_Meta' -d '{ "type": "jdbc","jdbc": { "url": "jdbc:postgresql://localhost:5432/testdb","user": "postgres","password": "passywordu","index": "source","type": "wham","sql": "select * from testtable;" }}'
然后我尝试了这是上面最后一个链接的修改版本.
curl -xpuT 'localhost:9200/_river/wham/_Meta' -d '{ "type": "jdbc","jdbc": { "strategy": "simple","poll": "5s","scale": 0,"autocommit": false,"fetchsize": 10,"max_rows": 0,"max_retrIEs": 3,"max_retrIEs_wait": "10s","url": "jdbc:postgresql://localhost:5432/testdb","sql": "select * from testtable","index": "wham" }}'
我目前正在使用最后一个卷发,http://127.0.0.1:9200 / _river / wham / _status给了我这个:
{ "_index": "_river","_type": "wham","_ID": "_status","_version": 4,"found": true,"_source": { "node": { "ID": "v1DmcSEOSbKfEbjRDWLYOg","name": "Miles Warren","transport_address": "inet[/192.168.43.211:9300]" } }}
所以河流在那里,但我没有看到任何查询到达我的postgresql数据库引擎.我相应地设置了:
su - postgresinitdb --locale en_US.UTF-8 -E UTF8 -D '/tmp/testdb'postgres -D /tmp/testdbcreatedb testdbpsql -d testdbCREATE table testtable ( source varchar(20) NOT NulL,destination varchar(20) NOT NulL,service int,NOT NulL);INSERT INTO testtable VALUES('192.168.0.10','192.168.0.1',80)INSERT INTO testtable VALUES('192.168.0.11','192.168.0.2',21)
我可以在默认端口查询数据库,它使用用户名和密码运行正常.
我哪里出错了?我是否误解了elasticsearch或者我不应该做/ wham / _search并从提到的SQL查询中获取所有结果?
查询1)
curl -xpuT 'localhost:9200/_river/wham/_Meta' -d '{ "type" : "jdbc","jdbc" : { "url" : "jdbc:postgresql://localhost:5432/testdb","user" : "postgres","password" : "passywordu","index" : "source","type" : "wham","sql" : "select * from testtable;" } }'
同时使用上面的查询
您创建名为“source”的索引.因为你创建了一个索引类型的wham.
所以在执行上面的卷曲之后.您需要使用以下格式查询数据
http://127.0.0.1:9200/source/wham/_search
它意味着在索引“source”中搜索数据并输入“wham”.
查询2)
curl -xpuT 'localhost:9200/_river/wham/_Meta' -d '{"type" : "jdbc","jdbc" : { "strategy" : "simple","poll" : "5s","scale" : 0,"autocommit" : false,"fetchsize" : 10,"max_rows" : 0,"max_retrIEs" : 3,"max_retrIEs_wait" : "10s","url" : "jdbc:postgresql://localhost:5432/testdb","sql" : "select * from testtable","type": "typename",//add the type of documents to be indexed[like tables in RDBMS] "index" : "wham"} }'
同时使用上面的查询
你创建一个名为“wham”的索引.因为你创建了一个索引类型的wham.
所以在执行上面的卷曲之后.您需要使用以下格式查询数据
http://127.0.0.1:9200/wham/typename/_search [or] http://127.0.0.1:9200/wham/_search
它意味着在索引“wham”和indextype“typename”中搜索数据.
在尝试上面之前curl.delete _river索引并尝试.如果数据不重要清除数据文件夹并尝试..!
希望能帮助到你..!
