# 配置
vi /etc/profile
# 添加如下
export FLUME_HOME=/usr/local/software/flume-1.9.0
export PATH=$FLUME_HOME/bin:$PATH
# 生效

# 在如下路径下新建文件
[root@master test]# pwd
/usr/local/software/flume-1.9.0/conf/test
[root@master test]# ls

[root@master test]# vi test.conf 

# 编写如下内容
# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444
# 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

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

# 进入如下目录启动
