版本flume 1.6 kafka2.11
flume中缺少flume-ng-sql-source的jar包需要去下载，下载地址可以是：https://github.com/keedio/flume-ng-sql-source.git 但比较麻烦，也可以下载已经弄好的jar：https://download.csdn.net/download/chongxin1/9892184
第一步：把下载好的flume-ng-sql-source的jar包放入到，flume的lib目录下。
第二步：我用的是oracle所以，就把oracle的jdbc包放到flume的lib目录下。我放的是ojdbc5.jar
第三步：配置flume的conf配置文件。
vi sql-kafka.conf 具体配置如下：
agentTest.channels = channelTest
agentTest.sources = sourceTest
agentTest.sinks = sinkTest
###########sql source#################
# For each Test of the sources, the type is defined
agentTest.sources.sourceTest.type = org.keedio.flume.source.SQLSource
agentTest.sources.sourceTest.hibernate.connection.url = jdbc:oracle:thin:@192.168.200.8:1521/orcl
# Hibernate Database connection properties
agentTest.sources.sourceTest.hibernate.connection.user = typpcits
agentTest.sources.sourceTest.hibernate.connection.password = typpcits
agentTest.sources.sourceTest.hibernate.connection.autocommit = true
agentTest.sources.sourceTest.hibernate.dialect = org.hibernate.dialect.Oracle10gDialect
agentTest.sources.sourceTest.hibernate.connection.driver_class = oracle.jdbc.driver.OracleDriver
agentTest.sources.sourceTest.run.query.delay=1
agentTest.sources.sourceTest.status.file.path = /opt/flume
agentTest.sources.sourceTest.status.file.name = agentTest.sqlSource.status
# Custom query
agentTest.sources.sourceTest.custom.query = SELECT * FROM ITS_BASE_AREA
agentTest.sources.sourceTest.batch.size = 6000
agentTest.sources.sourceTest.max.rows = 1000
agentTest.sources.sourceTest.hibernate.connection.provider_class = org.hibernate.connection.C3P0ConnectionProvider
agentTest.sources.sourceTest.hibernate.c3p0.min_size=1
agentTest.sources.sourceTest.hibernate.c3p0.max_size=10
##############################
agentTest.channels.channelTest.type = memory
agentTest.channels.channelTest.capacity = 10000
agentTest.channels.channelTest.transactionCapacity = 10000
agentTest.channels.channelTest.byteCapacityBufferPercentage = 20
agentTest.channels.channelTest.byteCapacity = 1600000
agentTest.sinks.sinkTest.type = org.apache.flume.sink.kafka.KafkaSink
agentTest.sinks.sinkTest.topic = TestTopic
agentTest.sinks.sinkTest.brokerList = 192.168.72.129:9092,192.168.72.130:9092,192.168.72.131:9092
agentTest.sinks.sinkTest.requiredAcks = 1
agentTest.sinks.sinkTest.batchSize = 20
agentTest.sinks.sinkTest.channel = channelTest
agentTest.sinks.sinkTest.channel = channelTest
agentTest.sources.sourceTest.channels=channelTest以上需要替换别忘记换了。
第四步：在flume bin路径下执行命令：
./bin/flume-ng agent -n agentTest -c conf -f conf/sql-kafka.conf -Dflume.root.logger=INFO,console
第五步：在kafka主题TestTopic上看有没有数据。在路径kafka的bin下执行命令：
./kafka-console-consumer.sh --zookeeper 192.168.72.129:2181 --topic TestTopic --from-beginning
如果成功的话，这时候就可以看见你查询oracle的数据了。
