一、配置启动flume

①flume的配置文件  conf/flume-conf.properties（这个文件一般是flume-conf.properties.default），复制修改后缀即可；

配置文件如下：

agent1.channels = ch1
    agent1.sources = avro-source1
    agent1.sinks = log-sink1

# 定义channel
    agent1.channels.ch1.type = memory    #mem channel

# 定义source
    agent1.sources.avro-source1.channels = ch1
    agent1.sources.avro-source1.type = avro        #avro source
    agent1.sources.avro-source1.bind = 0.0.0.0
    agent1.sources.avro-source1.port = 41414

# 定义sink
    agent1.sinks.log-sink1.channel = ch1
    agent1.sinks.log-sink1.type = logger                #logger sink

启动flume

bin/flume-ng agent --conf conf --conf-file conf/flume-conf.properties --name agent1 -Dflume.root.logger=INFO,console

二、log4j的配置

①在log4j.properties文件中添加flume appender

log4j.rootLogger=INFO,flume   #日志级别，info和flume

log4j.appender.flume = org.apache.flume.clients.log4jappender.Log4jAppender
    log4j.appender.flume.Hostname = 192.168.57.133    #flume地址
    log4j.appender.flume.Port = 41414                          #flume source监听的端口
    log4j.appender.flume.UnsafeMode = true
    log4j.appender.flume.layout=org.apache.log4j.PatternLayout 
    log4j.appender.flume.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c] [%p] - %m%n

三、测试

在maven中添加flume appender依赖

<dependency>
<groupId>org.apache.flume.flume-ng-clients</groupId>
<artifactId>flume-ng-log4jappender</artifactId>
<version>1.6.0</version>
</dependency>

编写简单的测试类：

public class Log4jTest {Logger logger = LoggerFactory.getLogger(Log4jTest.class);   /*** 测试flume* @Title: flumeTest * @Description: TODO* @param @throws Exception    * @return void    * @throws*/@Testpublic void flumeTest() throws Exception {while(true){logger.info("spider", System.currentTimeMillis());try {Thread.sleep(1000);} catch (Exception e) {// TODO: handle exceptione.printStackTrace();}}}

运行测试类，可以看到flume在控制台的输出
