Logstash从数据库一次同步多张表

xiaoxiao2021-02-28  37

一次同步多张表是开发中的一般需求。之前研究了很久找到方法,但没有详细总结。  博友前天在线提问,说明这块理解的还不够透彻。  我整理下,  一是为了尽快解决博友问题,  二是加深记忆,便于未来产品开发中快速上手。

1、同步原理

原有ES专栏中有详解,不再赘述。详细请参考我的专栏:  深入详解Elasticsearch  以下是通过ES5.4.0, logstash5.4.1 验证成功。  可以确认的是2.X版本同样可以验证成功。

2、核心配置文件

input { stdin { } jdbc { type => "cxx_article_info" # mysql jdbc connection string to our backup databse 后面的test对应mysql中的test数据库 jdbc_connection_string => "jdbc:mysql://110.10.15.37:3306/cxxwb" # the user we wish to excute our statement as jdbc_user => "root" jdbc_password => "xxxxx" record_last_run => "true" use_column_value => "true" tracking_column => "id" last_run_metadata_path => "/opt/logstash/bin/logstash_xxy/cxx_info" clean_run => "false" # the path to our downloaded jdbc driver jdbc_driver_library => "/opt/elasticsearch/lib/mysql-connector-java-5.1.38.jar" # the name of the driver class for mysql jdbc_driver_class => "com.mysql.jdbc.Driver" jdbc_paging_enabled => "true" jdbc_page_size => "500" statement => "select * from cxx_article_info where id > :sql_last_value" #定时字段 各字段含义(由左至右)分、时、天、月、年,全部为*默认含义为每分钟都更新 schedule => "* * * * *" #设定ES索引类型 } jdbc { type => "cxx_user" # mysql jdbc connection string to our backup databse 后面的test对应mysql中的test数据库 jdbc_connection_string => "jdbc:mysql://110.10.15.37:3306/cxxwb" # the user we wish to excute our statement as jdbc_user => "root" jdbc_password => "xxxxxx" record_last_run => "true" use_column_value => "true" tracking_column => "id" last_run_metadata_path => "/opt/logstash/bin/logstash_xxy/cxx_user_info" clean_run => "false" # the path to our downloaded jdbc driver jdbc_driver_library => "/opt/elasticsearch/lib/mysql-connector-java-5.1.38.jar" # the name of the driver class for mysql jdbc_driver_class => "com.mysql.jdbc.Driver" jdbc_paging_enabled => "true" jdbc_page_size => "500" statement => "select * from cxx_user_info where id > :sql_last_value" #以下对应着要执行的sql的绝对路径。 #statement_filepath => "/opt/logstash/bin/logstash_mysql2es/department.sql" #定时字段 各字段含义(由左至右)分、时、天、月、年,全部为*默认含义为每分钟都更新 schedule => "* * * * *" #设定ES索引类型 } } filter { mutate { convert => [ "publish_time", "string" ] } date { timezone => "Europe/Berlin" match => ["publish_time" , "ISO8601", "yyyy-MM-dd HH:mm:ss"] } #date { # match => [ "publish_time", "yyyy-MM-dd HH:mm:ss,SSS" ] # remove_field => [ "publish_time" ] # } json { source => "message" remove_field => ["message"] } } output { if [type]=="cxxarticle_info" { elasticsearch { #ESIP地址与端口 hosts => "10.100.11.231:9200" #ES索引名称(自己定义的) index => "cxx_info_index" #自增ID编号 # document_id => "%{id}" } } if [type]=="cxx_user" { elasticsearch { #ESIP地址与端口 hosts => "10.100.11.231:9200" #ES索引名称(自己定义的) index => "cxx_user_index" #自增ID编号 # document_id => "%{id}" } } } 123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104

3、同步成功结果

4、扩展

1)多个表无非就是在input里面多加几个类型,在output中多加基础  类型判定。  举例:

if [type]=="cxx_user" 1

2)input里的type和output if判定的type**保持一致**,该type对应ES中的type。

后记

死磕ES,有问题欢迎大家提问探讨!
