准备工作

  1. 修改Linux主机名

Vim /etc/sysconfig/network

添加 HOSTNAME=h1

  1. 修改IP

 vim /etc/sysconfig/network-scripts/ifcfg-eth0 

修改IPADDR=192.168.137.11

  1. 修改主机名和IP的映射关系

Vim /etc/hosts

添加192.168.137.11  h1

  1. 关闭防火墙

 service iptables stop

  1. ssh免登陆

ssh-keygen –t rsa //产生公钥和私钥

 

拷贝公钥到其他电脑(h2为主机名)

ssh-copy-id -i h2

  1. 安装JDK，配置环境变量等

这里可以在一台电脑上配置，然后拷贝到其他电脑

scp –r /home/jdk/  h2:/home/

 

都做完可以重启一下电脑

 //----------------------------zookeeper集群安装-------------------------------------
 //-----------------------------------------------------------------------------------

安装zookeeper

解压 tar –zxvf zookeeper-3.4.6.tar.gz

1.修改配置文件conf/ zoo_sample.cfg  为zoo.cfg

mv zoo_sample.cfg zoo.cfg

打开修改内容：

dataDir=/home/gj/zookeeper-3.4.6/data  //数据目录,可随意定义

最后面添加：

server.1=h4:2888:3888

server.2=h5:2888:3888

server.3=h6:2888:3888

 

// server.X=A:B:C

其中X是一个数字, 表示这是第几号server.

A是该server所在的IP地址.

B配置该server和集群中的leader交换消息所使用的端口.

C配置选举leader时所使用的端口. 

注意这里需要创建data文件夹

进入data文件夹创建文件myid  内容为1

1表示这是第几号server, 与server.X=A:B:C中的X对应

 

2.将配置到的zookeeper拷贝到其他电脑（h2,h3）上

使用 scp -r 命令

分别修改 myid文件内容为2,3

 

  1. 启动三个节点的 bin目录下的./zkServer.sh start

也可以将zookeeper 配置到环境变量里面

6.slaves

  h5

  h6

将在一台电脑上配置好的hadoop拷贝到其他电脑

 

启动hadoop  和zookeeper（已配置到环境变量里面）

1.先启动zookeeper在h4,h5,h6上

  zkServer.sh start

 查看状态zkServer.sh status（会发现有一个leader，两个follower）

2. 启动journalnode(在h1上启动)

   hadoop-daemons.sh start journalnode

3．格式化HDFS(在h1上启动)

hadoop namenode –format

此时会在hadoop目录里面产生tmp文件夹，将这个文件夹拷贝到h2上

  1. 格式化ZK(在h1上启动)

hdfs zkfc –formatZK

  1. 启动hadoop(在h1上启动)

start-all.sh

此时可能在h3上的resourceManager没有启动，可以进入h3启动start-yarn.sh

这时就可以通过web查看hadoop集群的各个状态，也可以用jps 命令查看进程

 //----------------------------hbase集群安装-------------------------------------
 //-----------------------------------------------------------------------------------

hbase 集群配置

  1. conf/hbase-env.sh

java_home=java路径

export HBASE_MANAGES_ZK=false 

使用独立的ZooKeeper时需要修改HBASE_MANAGES_ZK值为false，为不使用默认ZooKeeper实例。

 

2. conf/hbase-site.xml

 

<property>
 <name>hbase.rootdir</name>
 <value>hdfs://h1:9000/hbase</value>
</property>
<property>
 <name>hbase.cluster.distributed</name>
 <value>true</value>
</property>
<property>
<name>hbase.master</name>
<value>h1:60000</value>
</property>
 <property>
 <name>hbase.master.port</name>
 <value>60000</value>
 <description>The port master should bind to.</description>
 </property>
 
 <property>
   <name>hbase.zookeeper.quorum</name>
   <value>h4,h5,h6</value>
 </property>

 

3.conf/ regionservers

h4

h5

h6

 

启动hbase

在h1 上

start-hbase.sh

在h2上

start-hbase.sh

 

这是可以通过web查看hbase的状态  ，会发现像namenode一样有一个Active 状态的hmaster和Standby 状态的hmaster

 

至此完成集群。

 //-----------------------------------------------------------------------------------

storm的集群安装与配置

机器：

192.168.180.101

192.168.187.16

需要准备的软件有：

zookeeper(zookeeper-3.4.4.tar.gz),storm(storm-0.8.1.zip) ,jdk

1、配置zookeeper

解压zookeeper，将conf目录下的zoo_sample.cfg 重命名为：zoo.cfg

修改后内容为：

复制代码
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/data/zookeeper/data
dataLogDir=/data/zookeeper/log
# the port at which the clients will connect
clientPort=2181
#
# 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
server.1=192.168.187.16:2888:3888
server.2=192.168.180.101:2888:3888
复制代码

具体配置可以参看：
 http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_configuration

注意，最后两行的配置：

格式为：server.id=host:port:port

id只能为数字 1-255，同时需要在 dataDir目录下面新建一个文件名为myid的文件，里面的内容只有一行："id"

Every machine that is part of the ZooKeeper ensemble should know about every other machine in the ensemble. You accomplish this with the series of lines of the form server.id=host:port:port. The parameters host and port are straightforward. You attribute the server id to each machine by creating a file named myid, one for each server, which resides in that server's data directory, as specified by the configuration file parameterdataDir.

接着还需要添加环境变量：

export ZOOKEEPER_HOME=/home/zhxia/apps/db/zookeeper

两台机器上环境配置相同，但是myid文件内的id指不一样

 2、配置storm

解压storm

进入conf目录,编辑storm.yaml文件

复制代码
########## These MUST be filled in for a storm configuration
 storm.zookeeper.servers:
     - "192.168.187.16"
     - "192.168.180.101"

 nimbus.host: "192.168.187.16"

 storm.local.dir: "/data/storm/data"
 ##### These may optionally be filled in:

# List of custom serializations
# topology.kryo.register:
#     - org.mycompany.MyType
#     - org.mycompany.MyType2: org.mycompany.MyType2Serializer
#
## List of custom kryo decorators
# topology.kryo.decorators:
#     - org.mycompany.MyDecorator

# Locations of the drpc servers
# drpc.servers:
    # - "127.0.0.1"
     #- "server2"
## to nimbus 
#nimbus.childopts: "-Xmx1024m" 
#
## to supervisor 
#supervisor.childopts: "-Xmx1024m" 
#
## to worker 
#worker.childopts: "-Xmx768m"
复制代码

配置完成之后，开始启动zookeeper和storm

启动zookeeper

bin/zkServer.sh start

启动storm

bin/storm nimbus

bin/storm supervisor

bin/storm ui

浏览器打开： http://localhost:8080 查看集群的运行状态
