Ubuntu16.04+Flume1.8.0

?

1.下載apache-flume-1.8.0-bin.tar.gz

http://flume.apache.org/download.html

?

2.解壓到/usr/local/flume中

?

3.設(shè)置配置文件/etc/profile文件，增加flume的路徑

①vi /etc/profile

export FLUME_HOME=/usr/local/flume export PATH=$PATH:$FLUME_HOME/bin

②讓配置文件立即生效

source /etc/profile

?

4.檢查flume環(huán)境是否生效

flume-ng version

?

5.在/usr/local/flume/conf中增加一個(gè)example.conf文件

# example.conf: A single-node Flume configuration# 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 a1.channels.c1.transactionCapacity = 100# Bind the source and sink to the channel a1.sources.r1.channels = c1 a1.sinks.k1.channel = c1

?

6.啟動(dòng)flume

flume-ng agent --conf /usr/local/flume/conf --conf-file /usr/local/flume/conf/example.conf --name a1 -Dflume.root.logger=INFO,console

?

7.使用telnet連接到flume并發(fā)送數(shù)據(jù)

$ telnet localhost 44444 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. Hello world! <ENTER> OK

?

8.在flume的進(jìn)程中可以看到如下信息

[INFO - org.apache.flume.sink.LoggerSink.process(LoggerSink.java:95)] Event: { headers:{} body: 48 65 6C 6C 6F 20 57 6F 72 6C 64 21 0D Hello World!. }

?

?PS:當(dāng)你發(fā)送的數(shù)據(jù)超過16字節(jié)時(shí)，也只能最多顯示16字節(jié)，其實(shí)數(shù)據(jù)是能完全接收完全的！

如果發(fā)送數(shù)據(jù)真的超過最大長(zhǎng)度，會(huì)出現(xiàn)Client sent event exceeding the maximum length錯(cuò)誤。

可參考《flume-ng 測(cè)試過程中event丟失部分body數(shù)據(jù)》

?

以上。
