环境：三台虚拟机，系统是CentOS6.5
1.关闭防火墙，配置hosts，添加集群中主机和IP的映射关系
[grid@hadoop4 ~]$ cat /etc/hosts 127.0.0.1 localhost ::1 localhost 192.168.0.106 hadoop4 192.168.0.107 hadoop5 192.168.0.108 hadoop6
2.安装Java（JDK6或以上版本），配置JAVA_HOME 、CLASSPATH环境变量
[grid@hadoop4 ~]$ cat .bash_profile JAVA_HOME=/usr/java/jdk1.7.0_72 JRE_HOME=$JAVA_HOME/jre PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib export JAVA_HOME JRE_HOME PATH CLASSPATH
3.安装python
先确定你系统自带的Python版本，如果是2.6.6或者以上的不需要安装
[grid@hadoop4 ~]$ python Python 2.6.6 (r266:84292, Jan 22 2014, 09:42:36) [GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>
4.搭建Zookeeper集群
##下载解压## [grid@hadoop4 ~]$ wget http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz [grid@hadoop4 ~]$ tar -zxf zookeeper-3.4.6.tar.gz ##修改配置文件## [grid@hadoop4 ~]$ cd zookeeper-3.4.6/conf/ [grid@hadoop4 conf]$ cp -p zoo_sample.cfg zoo.cfg [grid@hadoop4 conf]$ vi zoo.cfg # The number of milliseconds of each tick tickTime=2000 ##服务器心跳时间，单位毫秒 # The number of ticks that the initial # synchronization phase can take initLimit=10 ##投票选择新leader的初始化时间 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 ##leader与follower心跳检测最大容忍时间，响应超过syncLimit*tickTime，leader认为follwer死掉，从服务器列表中删除follwer # the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. dataDir=/home/grid/zookeeper-3.4.6/data ##数据目录，需要手动创建 # dataLogDir= ##日志目录，不指定将使用和dataDir相同的设置 # the port at which the clients will connect clientPort=2181 ##监听client连接的端口 ##server.id=host:port:port，id是一个数字，表示这是第几号server，这个id也会被写到myid文件中；host是zookeeper服务器ip或主机名；第一个port是leader与follwer通讯所使用的端口；第二个port是选举leader时所使用的端口 server.1=hadoop4:2888:3888 server.2=hadoop5:2888:3888 server.3=hadoop6:2888:3888 # the maximum number of client connections. # increase this if you need to handle more clients #maxClientCnxns=60 # # Be sure to read the maintenance section of the # administrator guide before turning on autopurge. # # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance # # The number of snapshots to retain in dataDir #autopurge.snapRetainCount=3 # Purge task interval in hours # Set to "0" to disable auto purge feature #autopurge.purgeInterval=1 ##手动创建数据目录## [grid@hadoop4 conf]$ cd /home/grid/zookeeper-3.4.6 [grid@hadoop4 zookeeper-3.4.6]$ mkdir data ##分发zookeeper## [grid@hadoop4 zookeeper-3.4.6]$ cd .. [grid@hadoop4 ~]$ scp -rp zookeeper-3.4.6 grid@hadoop5:/home/grid/ [grid@hadoop4 ~]$ scp -rp zookeeper-3.4.6 grid@hadoop6:/home/grid/ ##在数据目录下创建myid文件，写入id号，用来标识当前主机## [grid@hadoop4 ~]$ echo "1" > zookeeper-3.4.6/data/myid [grid@hadoop5 ~]$ echo "2" > zookeeper-3.4.6/data/myid [grid@hadoop6 ~]$ echo "3" > zookeeper-3.4.6/data/myid ##启动zookeeper## [grid@hadoop4 ~]$ zookeeper-3.4.6/bin/zkServer.sh start [grid@hadoop5 ~]$ zookeeper-3.4.6/bin/zkServer.sh start [grid@hadoop6 ~]$ zookeeper-3.4.6/bin/zkServer.sh start ##查看zookeeper状态## [grid@hadoop4 ~]$ zookeeper-3.4.6/bin/zkServer.sh status JMX enabled by default Using config: /home/grid/zookeeper-3.4.6/bin/../conf/zoo.cfg Mode: follower [grid@hadoop5 ~]$ zookeeper-3.4.6/bin/zkServer.sh status JMX enabled by default Using config: /home/grid/zookeeper-3.4.6/bin/../conf/zoo.cfg Mode: leader [grid@hadoop6 ~]$ zookeeper-3.4.6/bin/zkServer.sh status JMX enabled by default Using config: /home/grid/zookeeper-3.4.6/bin/../conf/zoo.cfg Mode: follower
5.安装Storm
##下载解压## [grid@hadoop4 ~]$ wget http://mirrors.cnnic.cn/apache/storm/apache-storm-0.9.4/apache-storm-0.9.4.tar.gz [grid@hadoop4 ~]$ tar -zxf apache-storm-0.9.4.tar.gz [grid@hadoop4 ~]$ mv apache-storm-0.9.4 storm-0.9.4 ##修改配置项## [grid@hadoop4 conf]$ vim storm.yaml # Licensed to the Apache Software Foundation (ASF) under one # or more contributor license agreements.
