启动hadoop
./start-all.sh
jps
配置flume环境变量
修改/etc/profile
export FLUME_HOME=/app/flume-1.5.2
export FLUME_CONF_DIR=$FLUME_HOME/conf
export PATH=$PATH:$FLUME_HOME/bin
source /etc/profile
echo $PATH
设置 flume-env.sh 配置文件
在 $FLUME_HOME/conf 下复制改名 flume-env.sh.template 为 flume-env.sh，修改 conf/ flume-env.sh 配置文件
cp flume-env.sh.template flume-env.sh
sudo vi flume-env.sh
cp flume-env.sh.template flume-env.sh
sudo vi flume-env.sh
修改 flume-conf 配置文件
在 $FLUME_HOME/conf 目录下修改 flume-conf.properties.template 文件，复制并改名为 flume-conf.properties
cp flume-conf.properties.template flume-conf.properties
sudo vi flume-conf.properties
修改内容，用来读取hadoop运行时生成的namenode日志文件,并写入hdfs中

运行flume
./bin/flume-ng agent --conf ./conf/ --conf-file ./conf/flume-conf.properties --name a1 -Dflume.root.logger=INFO,console
打开hdfs查看导入的日志
