1. 安装部署

1.1 环境要求

1.使用的JDK的版本必须是1.6或者更高版本，本实例中使用的是JDK1.6

2.使用的hadoop的版本必须是Hadoop0.20.205.1及以上版本，本实例中使用的是Hadoop1.0.1版本。

3.为了运行HICC，需要使用HBase0.90.4版本

1.2 版本选择

　　这里使用0.5版本

1.3 执行步骤

1.首先下载的chukwa的版本是0.5版本，下载链接如下：

http://labs.renren.com/apache-mirror/incubator/chukwa/chukwa-0.5.0/

下载如下的两个文件：

chukwa-incubating-0.5.0.tar.gz

chukwa-incubating-src-0.5.0.tar.gz

将如上的两个gz文件进行解压缩，

2.然后将chukwa-incubating-src-0.5.0下的conf目录和script目录拷贝到

chukwa-incubating-0.5.0目录下，并将chukwa-incubating-0.5.0重命名为chukwa

1.3 目录规范

程序目录

 tar -zxvf chukwa-incubating-0.5.0.tar.gz -C /usr/local/cloud/src/

 cd /usr/local/cloud/

 ln -s -f /usr/local/cloud/src/chukwa-incubating-0.5.0 chukua

数据目录

 mkdir /data/logs/chukwa

 mkdir /data/pids/chukwa

1.4 修改配置

 vim /etc/profile

 export CHUKWA_HOME=/usr/local/cloud/chukwa

 export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$CHUKWA_HOME/bin:$PATH

 source /etc/profile

代理器配置

  • 使用 $CHUKWA  /etc/chukwa/agents 指定代理器地址
#配置代理这里介绍单机模式

localhost
  • 使用 $CHUKWA  /etc/chukwa/chukwa-agent-conf.xml 配置代理器参数
 <!-- 设置轮询检测文件内容变化的间隔时间  -->

 <property>

     <name>chukwaAgent.adaptor.context.switch.time</name>

     <value>5000</value>

 </property>

 <!-- 设置读取文件增量内容的最大值  -->

 <property>

     <name>chukwaAgent.fileTailingAdaptor.maxReadSize</name>

     <value>2097152</value>

 </property>

收集器配置

  • 使用 $CHUKWA   /etc/chukwa/collectors 指定收集器地址
 # 单机部署的情况下与agents相同

 localhost
  • 使用 $CHUKWA  /etc/chukwa/chukwa-collector-conf.xml 配置收集器参数
 <!-- Chukwa 0.5 版本添加了写入到HBase的实现, 如果不需要则应恢复默认 -->

 <!-- Sequence File Writer parameters -->

 <property>

     <name>chukwaCollector.pipeline</name>

     <value>org.apache.hadoop.chukwa.datacollection.writer.SocketTeeWriter,org.apache.hadoop.chukwa.datacollection.writer.Se#

 </property>

 <!-- 设置服务端地址  -->

 <property>

     <name>writer.hdfs.filesystem</name>

     <value>hdfs://hadooptest:9000</value>

 </property>

全局配置

 # 在 $CHUKWA_HOME/etc/chukwa/chukwa-env.sh 添加或修改如下项

 export JAVA_HOME=/usr/java/default

 export CLASSPATH=.:$JAVA_HOME/lib

 export HADOOP_HOME=/usr/local/cloud/hadoop

 export CHUKWA_HOME=/usr/local/cloud/chukua

 export CHUKWA_CONF_DIR=${CHUKWA_HOME}/etc/chukwa

 export CHUKWA_PID_DIR=/data/pids/chukwa

 export CHUKWA_LOG_DIR=/data/logs/chukwa

监测文件设置

 # 在 $CHUKWA_HOME/etc/chukwa/initial_adaptors 中添加要监测的日志文件, 但一般使用 telnet 链接到服务端的方式添加

 # 格式为 add [name =] <adaptor_class_name> <datatype> <adaptor specific params> <initial offset>

 # 依次为: 监测接口的实现类 数据类型 起始点 日志文件 已收集的文件大小

 add filetailer.CharFileTailingAdaptorUTF8 typeone 0 /data/logs/web/typeone.log 0

 add filetailer.CharFileTailingAdaptorUTF8 typetwo 0 /data/logs/web/typetwo.log 0

2 启动服务

2.1 启动收集器进程

2.2 启动代理器进程

sbin/start-agents.sh

2.3 启动数据处理进程

3 收集测试

3.2 模拟WEB日志

 # 在 /data/logs/web/weblogadd.sh 中写入如下内容

 #!/bin/bash

 cat /data/logs/web/webone >> /data/logs/web/typeone.log

 cat /data/logs/web/webtwo >> /data/logs/web/typetwo.log

 # 设置脚本文件可执行

 chmod +x weblogadd.sh

 # 在 /etc/crontab 中添加定时任务以模拟WEB日志生成

 */1 * * * * hadoop /data/logs/web/weblogadd.sh

3.3 添加日志监控

 # 链接到服务端的 telnet 服务

 telnet hadooptest 9093

 add org.apache.hadoop.chukwa.datacollection.adaptor.filetailer.CharFileTailingAdaptorUTF8 typeone 0 /data/logs/web/typeone.log 0

 add org.apache.hadoop.chukwa.datacollection.adaptor.filetailer.CharFileTailingAdaptorUTF8 typetwo 0 /data/logs/web/typetwo.log 0
