Flume连接oracle实时推送数据到kafka

版本号：

RedHat6.5   JDK1.8    flume-1.6.0   kafka_2.11-0.8.2.1

flume安装

RedHat6.5安装单机flume1.6：RedHat6.5安装单机flume1.6

kafka安装

RedHat6.5安装kafka集群 ： RedHat6.5安装kafka集群

1、下载flume-ng-sql-source-1.4.3.jar

CSDN下载地址：http://download.csdn.net/detail/chongxin1/9892184

flume-ng-sql-source-1.4.3.jar是flume用于连接数据库的重要支撑jar包。

2、把flume-ng-sql-source-1.4.3.jar放到flume的lib目录下

3、把oracle（此处用的是oracle库）的驱动包放到flume的lib目录下

oracle的jdbc驱动包，放在oracle安装目录下，路径为：D:\app\product\11.2.0\dbhome_1\jdbc\lib

如图：

把ojdbc5.jar放到flume的lib目录下，如图：

4、新建flume-sql.conf

在conf目录新建flume-sql.conf :

touch /usr/local/flume/apache-flume-1.6.0-bin/conf/flume-sql.conf
sudo gedit /usr/local/flume/apache-flume-1.6.0-bin/conf/flume-sql.conf

flume-sql.conf输入以下内容：

agentOne.channels = channelOne
agentOne.sources = sourceOne
agentOne.sinks = sinkOne
###########sql source#################
# For each one of the sources, the type is defined
agentOne.sources.sourceOne.type = org.keedio.flume.source.SQLSource
agentOne.sources.sourceOne.hibernate.connection.url = jdbc:oracle:thin:@192.168.168.100:1521/orcl
# Hibernate Database connection properties
agentOne.sources.sourceOne.hibernate.connection.user = flume
agentOne.sources.sourceOne.hibernate.connection.password = 1234
agentOne.sources.sourceOne.hibernate.connection.autocommit = true
agentOne.sources.sourceOne.hibernate.dialect = org.hibernate.dialect.Oracle10gDialect
agentOne.sources.sourceOne.hibernate.connection.driver_class = oracle.jdbc.driver.OracleDriver
agentOne.sources.sourceOne.run.query.delay=10000
agentOne.sources.sourceOne.status.file.path = /tmp
agentOne.sources.sourceOne.status.file.name = sqlSource.status
# Custom query
agentOne.sources.sourceOne.start.from = 0
agentOne.sources.sourceOne.custom.query = select sysdate from dual
agentOne.sources.sourceOne.batch.size = 1000
agentOne.sources.sourceOne.max.rows = 1000
agentOne.sources.sourceOne.hibernate.connection.provider_class = org.hibernate.connection.C3P0ConnectionProvider
agentOne.sources.sourceOne.hibernate.c3p0.min_size=1
agentOne.sources.sourceOne.hibernate.c3p0.max_size=10
##############################
agentOne.channels.channelOne.type = memory
agentOne.channels.channelOne.capacity = 10000
agentOne.channels.channelOne.transactionCapacity = 10000
agentOne.channels.channelOne.byteCapacityBufferPercentage = 20
agentOne.channels.channelOne.byteCapacity = 800000
 
agentOne.sinks.sinkOne.type = org.apache.flume.sink.kafka.KafkaSink
agentOne.sinks.sinkOne.topic = test
agentOne.sinks.sinkOne.brokerList = 192.168.168.200:9092
agentOne.sinks.sinkOne.requiredAcks = 1
agentOne.sinks.sinkOne.batchSize = 20
agentOne.sinks.sinkOne.channel = channelOne
 
agentOne.sinks.sinkOne.channel = channelOne
agentOne.sources.sourceOne.channels=channelOne

5、flume-ng启动flume-sql.conf和测试

 

cd /usr/local/flume/apache-flume-1.6.0-bin
bin/flume-ng agent --conf conf --conf-file conf/flume-sql.conf --name agentOne -Dflume.root.logger=INFO,console

运行成功日志如下：

2017-07-08 00:12:55,393 (lifecycleSupervisor-1-1) [INFO - org.apache.flume.instrumentation.MonitoredCounterGroup.register(MonitoredCounterGroup.java:120)] Monitored counter group for type: SINK, name: sinkOne: Successfully registered new MBean.

启动kafka的消费者，监听topic主题：

kafka-console-consumer.sh --zookeeper localhost:2181 --topic test

运行成功日志如下：

[root@master kafka_2.11-0.9.0.0]# kafka-console-consumer.sh --zookeeper localhost:2181 --topic test  
"2017-07-08 00:28:53.0"

6、常见报错解决办法

 2017-06-27 16:26:01,293 (C3P0PooledConnectionPoolManager[identityToken->1hgey889o1sjxqn51anc3fr|29938ba5]-AdminTaskTimer) [WARN - com.mchange.v2.async.ThreadPoolAsynchronousRunner$DeadlockDetector.run(ThreadPoolAsynchronousRunner.java:759)] com.mchange.v2.async.ThreadPoolAsynchronousRunner$DeadlockDetector@2d6227f3 -- APPARENT DEADLOCK!!! Complete Status:​

连接超时，造成死锁，仔细检查jdbc:oracle:thin:@192.168.168.100:1521/orcl，用户名/密码是否正确；

如果正确，还是连接不上，请检查oralce数据库是否开启了防火墙，如果是，添加入站规则或直接关闭防火墙。
