1.下载

http://mirrors.tuna.tsinghua.edu.cn/apache/flume/1.7.0/

2.上传到服务器并解压

上传apache-flume-1.7.0-bin.tar.gz到/home/youxin/hadoop,然后解压缩

tar -zxvf apache-flume-1.7.0-bin.tar.gz

3.修改配置文件

cd apache-flume-1.7.0-bin/conf

cp flume-env.sh.template flume-env.sh

vi flume-env.sh

修改其中的

4.验证

[root@yx bin]# /home/youxin/hadoop/apache-flume-1.7.0-bin/bin/flume-ng version
Flume 1.7.0
Source code repository: https://git-wip-us.apache.org/repos/asf/flume.git

出现上面信息表示安装成功了

5.使用

5.1 EXEC执行一个给定的命令获得输出的源,如果要使用tail命令，必选使得file足够大才能看到输出内容

创建配置文件：

vi /home/youxin/hadoop/apache-flume-1.7.0-bin/conf/exec_tail.conf

a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = exec
a1.sources.r1.channels = c1
a1.sources.r1.command = tail -f /home/youxin/api/log/api8888.log

# Describe the sink
a1.sinks.k1.type = logger

# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

启动agent a1

/home/youxin/hadoop/apache-flume-1.7.0-bin/bin/flume-ng agent -c . -f /home/youxin/hadoop/apache-flume-1.7.0-bin/conf/exec_tail.conf -n a1 -Dflume.root.logger=INFO,console
