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
*/
@Test
public void flumeTest() throws Exception {
while(true){
logger.info("spider", System.currentTimeMillis());
try {
Thread.sleep(1000);
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
}
