将node03机器上面解压后的flume文件夹拷贝到node02机器上面去
cd /export/servers
scp -r apache-flume-1.8.0-bin/ node02:$PWD
在node02机器配置我们的flume
cd /export/servers/ apache-flume-1.8.0-bin/conf
vim tail-avro-avro-logger.conf

直接将node03下面的脚本和数据拷贝到node02即可,node03机器上执行以下命令
cd /export/servers
scp -r shells/ taillogs/ node02:$PWD
在node03机器上开发flume的配置文件
cd /export/servers/apache-flume-1.8.0-bin/conf

node03机器启动flume进程
cd /export/servers/apache-flume-1.8.0-bin bin/flume-ng agent -c conf -f conf/avro-hdfs.conf -n a1
node02机器启动flume进程
cd /export/servers/apache-flume-1.8.0-bin/ bin/flume-ng agent -c conf -f conf/tail-avro-avro-logger.conf -n a1
node02机器启shell脚本生成文件
cd /export/servers/shells
sh tail-file.sh
