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。

《魔兽世界》大逃杀!60人新游玩模式《强袭风暴》3月21日上线
暴雪近日发布了《魔兽世界》10.2.6 更新内容,新游玩模式《强袭风暴》即将于3月21 日在亚服上线,届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。
艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕,并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时,他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中,玩家将会进入一个全新的海盗主题大逃杀式限时活动,其中包含极高的风险和史诗级的奖励。
《强袭风暴》不是普通的战场,作为一个独立于主游戏之外的活动,玩家可以用大逃杀的风格来体验《魔兽世界》,不分职业、不分装备(除了你在赛局中捡到的),光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式,玩家在加入海盗主题的预赛大厅区域前,可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹,《巨龙崛起》和《魔兽世界:巫妖王之怒 经典版》的玩家都可以获得奖励。
