Hadoop 搭建Flume环境

环境

• CentOS 6.8 64位 1核 2GB

• JDK 1.7.0_75 64 位

• Hadoop 1.1.2

• Flume 1.5.2

安装Flume

• 下载 flume 安装包

$ wget http://archive.apache.org/dist/flume/1.5.2/apache-flume-1.5.2-bin.tar.gz

• 解压 flume 安装包

$ tar -xzf apache-flume-1.5.2-bin.tar.gz
$ mv apache-flume-1.5.2-bin /app/flume-1.5.2

解压后，将 apache-flume-1.5.2-bin 移动到 /app 目录下，并命名为 flume-1.5.2。

• 修改 /etc/profile 文件

$ sudo vi /etc/profile

• 添加 flume 环境变量

export FLUME_HOME=/app/flume-1.5.2
export FLUME_CONF_DIR=$FLUME_HOME/conf
export PATH=$PATH:$FLUME_HOME/bin

• 保存生效

$ source /etc/profile

配置Flume

• 进入 /app/flume-1.5.2/conf 目录

$ cd /app/flume-1.5.2/conf

• 复制 flume-env.sh.template 命名为 flume-env.sh

$ cp flume-env.sh.template flume-env.sh

• 修改 flume-env.sh 文件

JAVA_HOME= /app/lib/jdk1.7.0_55
JAVA_OPTS="-Xms100m -Xmx200m -Dcom.sun.management.jmxremote"

修改以上两项配置。

验证配置完成

• 复制 flume-conf.properties.template 命名为 flume-conf.properties

$ cp flume-conf.properties.template flume-conf.properties

• 修改 flume-conf.properties 文件

#  The configuration file needs to define the sources, the channels and the sinks.
#  Sources, channels and sinks are defined per agent, in this case called 'a1'
a1.sources = r1
a1.sinks = k1
a1.channels = c1

#  For each one of the sources, the type is defined
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444

# The channel can be defined as follows.
a1.sources.r1.channels = c1
#  Each sink's type must be defined
a1.sinks.k1.type = logger

# Specify the channel the sink should use
a1.sinks.k1.channel = c1

#  Each channel's type is defined.
a1.channels.c1.type = memory
#  Other config values specific to each type of channel(sink or source)
#  can be defined as well
#  In this case, it specifies the capacity of the memory channel
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

• 在 /app/flume-1.5.2/conf 目录执行

$ ./bin/flume-ng agent --conf ./conf/ --conf-file  ./conf/flume-conf.properties --name a1 -Dflume.root.logger=INFO,console

• 再打开一个终端，执行

$ curl localhost:44444
OK
