大数据Flume系列之Flume集群搭建

1. 概念

集群的意思是多台机器，最少有2台机器，一台机器从数据源中获取数据，将数据传送到另一台机器上，然后输出。接下来就要实现Flume集群搭建。集群如下图所示。

2. Flume搭建

2.1 部署准备

• 部署主机

1. 192.168.9.139 host14

2. 192.168.9.128 host15

• host14主机下载flume软件包

1. # cd /opt/tools

2. # wget http://mirrors.tuna.tsinghua.edu.cn/apache/flume/1.7.0/apache-flume-1.7.0-bin.tar.gz

• 上传解压flume

1. # mkdir -p /apps/svr/flume/

2. # tar -zxvf /opt/tools/apache-flume-1.7.0-bin.tar.gz -C /apps/svr/flume/

2.2 部署Flume

部署的是集群，需要在2台机安装Flume，host14作为push推送数据，host15作为pull获取数据后显示出来。

• 修改配置文件

1. # cd /apps/svr/flume/apache-flume-1.7.0-bin/conf/

2. # cp flume-env.sh.template flume-env.sh

3. # cp flume-conf.properties.template flume-telent.conf

4.  

5. # vim flume-env.sh

6. export JAVA_HOME=/apps/svr/java/jdk1.8.0_172

• host15主机部署Flume

# scp -r /apps/svr/flume/ host15:/apps/svr/

• 验证flume

1. # /apps/svr/flume/apache-flume-1.7.0-bin/bin/flume-ng version

2. Flume 1.7.0

3. Source code repository: https://git-wip-us.apache.org/repos/asf/flume.git

4. Revision: 511d868555dd4d16e6ce4fedc72c2d1454546707

5. Compiled by bessbd on Wed Oct 12 20:51:10 CEST 2016

6. From source with checksum 0d21b3ffdc55a07e1d08875872c00523

2.3 Flume集群配置

• 配置push.conf 

[host14]

# cd /apps/svr/flume/apache-flume-1.7.0-bin/conf
# vim push.conf

1. # Name the components on this agent

2. a2.sources= r1

3. a2.sinks= k1

4. a2.channels= c1

5.  

6. # Describe/configure the source

7. a2.sources.r1.type= spooldir

8. a2.sources.r1.spoolDir= /apps/svr/flume/logs

9. a2.sources.r1.channels= c1

10.  

11. # Use a channel which buffers events in memory

12. a2.channels.c1.type= memory

13. a2.channels.c1.keep-alive= 10

14. a2.channels.c1.capacity= 100000

15. a2.channels.c1.transactionCapacity= 100000

16.  

17. # Describe/configure the source

18. a2.sinks.k1.type= avro

19. a2.sinks.k1.channel= c1

20. a2.sinks.k1.hostname= host15

21. a2.sinks.k1.port= 8899

• 配置pull.conf

[host15]
# cd /apps/svr/flume/apache-flume-1.7.0-bin/conf
# vim pull.conf

1. # Name the components on this agent

2. a1.sources= r1

3. a1.sinks= k1

4. a1.channels= c1

5.  

6. # Describe/configure the source

7. a1.sources.r1.type= avro

8. a1.sources.r1.channels= c1

9. a1.sources.r1.bind= host15

10. a1.sources.r1.port= 8899

11.  

12. # Describe the sink

13. a1.sinks.k1.type= logger

14. a1.sinks.k1.channel = c1

15.  

16. # Use a channel which buffers events in memory

17. a1.channels.c1.type= memory

18. a1.channels.c1.keep-alive= 10

19. a1.channels.c1.capacity= 100000

20. a1.channels.c1.transactionCapacity= 100000

• 创建spoolDir目录

[host14]
# mkdir -p /apps/svr/flume/logs

2.4 Flume集群启动

• 启动pull主机

[host15]
# cd /apps/svr/flume/apache-flume-1.7.0-bin/
# ./bin/flume-ng agent -c conf -f conf/pull.conf -n a1 -Dflume.root.logger=INFO,console

显示如图所示则为启动成功

• 启动push主机

[host14]
# cd /apps/svr/flume/apache-flume-1.7.0-bin/
# ./bin/flume-ng agent -n a2 -c conf -f conf/push.conf -Dflume.root.logger=INFO,console

显示如图所示则为启动成功

• 验证连接

[host15]

显示如图所示表示连接成功

3. Flume测试

3.1 创建测试用例

[host14]
# cd /apps/svr/flume/logs/
# vim flume-use-case-test.log

1. HELLO WORLD!!!

2. HELLO FLUME!!!

3.2 验证测试

• pull主机

显示如图所示表示测试成功

• push主机

显示如图所示表示测试成功

结论：用例测试成功，证明Flume集群搭建成功。
