创建触发器和外部表

新增数据测试
test=# insert into pp (id,age) values (1,11); INSERT 0 1 test=# select * from pp; id | age ----+----- 1 | 11 (1 row) test=#
检查es数据
[root@rtm2 ~]# curl 'http://192.168.31.121:9200/es-node1/_search"took" : 104, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 2, "max_score" : 1.0, "hits" : [ { "_index" : "es-node1", "_type" : "pp", "_id" : "1", "_score" : 1.0, "_source":{"age": "11"} }, { "_index" : "es-node1", "_type" : "pp", "_id" : "2", "_score" : 1.0, "_source":{"age": "22"} } ] } } [root@rtm2 ~]#
创建更新触发器

补充:logstash同步pgsql数据到Elasticsearch
一、对于logstash的配置我就不在多说,主要是三部分,input、filter、output的配置
二、配置步骤
1、input配置
input { stdin { } jdbc { jdbc_connection_string => "jdbc:postgresql://127.0.0.1:5432/world" jdbc_user => "postgres" jdbc_password => "zhang123" jdbc_driver_library => "D:\logstash-6.4.0\bin\pgsql\postgresql-42.2.5.jar" jdbc_driver_class => "org.postgresql.Driver" jdbc_paging_enabled => "true" jdbc_page_size => "300000" use_column_value => "true" tracking_column => "id" statement_filepath => "D:\logstash-6.4.0\bin\pgsql\jdbc.sql" schedule => "* * * * *" type => "jdbc" jdbc_default_timezone =>"Asia/Shanghai" } }
2、filter配置
filter { json { source => "message" remove_field => ["message"] } }
3、output 配置,就是elasticsearch的基本配置
output { elasticsearch { hosts => ["localhost:9200"] index => "test_out" template => "D:\logstash-6.4.0\bin\pgsql\es-template.json" template_name => "t-statistic-out-logstash" template_overwrite => true document_type => "out" document_id => "%{id}" } stdout { codec => json_lines } }
以上就是整个logstash 的jdbc.conf
4、es-template.json的配置
{ "template" : "t-statistis-out-template", "order":1, "settings": { "index": { "refresh_interval": "5s" } }, "mappings": { "_default_": { "_all" : {"enabled":false}, "dynamic_templates": [ { "message_field" : { "match" : "message", "match_mapping_type" : "string", "mapping" : { "type" : "string", "index" : "not_analyzed" } } }, { "string_fields" : { "match" : "*", "match_mapping_type" : "string", "mapping" : { "type" : "string", "index" : "not_analyzed" } } } ], "properties": { "@timestamp": { "type": "date" }, "@version": { "type": "keyword" }, "id": { "type": "keyword" }, "name": { "type": "keyword" }, "pp": { "type": "keyword" } } } }, "aliases": {} }
最后就是就是下载好pgsql的连接驱动,这个官网可以下载;配置好自己的数据库表格的数据
启动命令:进入到logstash的bin目录下,自己的logstash配置都是放在bin的pgsql这个目录下面(这个自己随意创建位置都可以)
logstash.bat -f ./pgsql/jdbc.conf
以上为个人经验,希望能给大家一个参考,也希望大家多多支持。如有错误或未考虑完全的地方,望不吝赐教。
