分布式日志收集系统--Chukwa
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
1 tar -zxvf chukwa-incubating-0.5.0.tar.gz -C /usr/local/cloud/src/ 2 cd /usr/local/cloud/ 3 ln -s -f /usr/local/cloud/src/chukwa-incubating-0.5.0 chukua
数据目录
1 mkdir /data/logs/chukwa 2 mkdir /data/pids/chukwa
1.4 修改配置
1 vim /etc/profile 2 export CHUKWA_HOME=/usr/local/cloud/chukwa 3 export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$CHUKWA_HOME/bin:$PATH 4 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
1 <!-- 设置轮询检测文件内容变化的间隔时间 --> 2 <property> 3 <name>chukwaAgent.adaptor.context.switch.time</name> 4 <value>5000</value> 5 </property> 6 <!-- 设置读取文件增量内容的最大值 --> 7 <property> 8 <name>chukwaAgent.fileTailingAdaptor.maxReadSize</name> 9 <value>2097152</value> 10 </property>
收集器配置
- 使用 $CHUKWA /etc/chukwa/collectors 指定收集器地址
1 # 单机部署的情况下与agents相同 2 localhost
- 使用 $CHUKWA /etc/chukwa/chukwa-collector-conf.xml 配置收集器参数
1 <!-- 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 --> 2 <!-- Sequence File Writer parameters --> 3 <property> 4 <name>chukwaCollector.pipeline</name> 5 <value>org.apache.hadoop.chukwa.datacollection.writer.SocketTeeWriter,org.apache.hadoop.chukwa.datacollection.writer.Se# 6 </property> 7 8 <!-- 设置服务端地址 --> 9 <property> 10 <name>writer.hdfs.filesystem</name> 11 <value>hdfs://hadooptest:9000</value> 12 </property>
全局配置
1 # 在 $CHUKWA_HOME/etc/chukwa/chukwa-env.sh 添加或修改如下项 2 export JAVA_HOME=/usr/java/default 3 export CLASSPATH=.:$JAVA_HOME/lib 4 export HADOOP_HOME=/usr/local/cloud/hadoop 5 export CHUKWA_HOME=/usr/local/cloud/chukua 6 export CHUKWA_CONF_DIR=${CHUKWA_HOME}/etc/chukwa 7 export CHUKWA_PID_DIR=/data/pids/chukwa 8 export CHUKWA_LOG_DIR=/data/logs/chukwa
监测文件设置
1 # 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 2 # 格式为 add [name =] <adaptor_class_name> <datatype> <adaptor specific params> <initial offset> 3 # 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 4 add filetailer.CharFileTailingAdaptorUTF8 typeone 0 /data/logs/web/typeone.log 0 5 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
1 cd $CHUKWA_HOME/ 2 sbin/start-collectors.sh
2.2 启动代理器进程
sbin/start-agents.sh
2.3 启动数据处理进程
1 sbin/start-data-processors.sh

3.2 模拟WEB日志

3.3 添加日志监控
1 # 链接到服务端的 telnet 服务 2 telnet hadooptest 9093 3 add org.apache.hadoop.chukwa.datacollection.adaptor.filetailer.CharFileTailingAdaptorUTF8 typeone 0 /data/logs/web/typeone.log 0 4 add org.apache.hadoop.chukwa.datacollection.adaptor.filetailer.CharFileTailingAdaptorUTF8 typetwo 0 /data/logs/web/typetwo.log 0
