搭建ubuntu版hadoop集群
用到的工具:VMware、hadoop-2.7.2.tar、jdk-8u65-linux-x64.tar、ubuntu-16.04-desktop-amd64.iso
1、 在VMware上安装ubuntu-16.04-desktop-amd64.iso
单击“创建虚拟机”è选择“典型(推荐安装)”è单击“下一步”
è点击完成
修改/etc/hostname
vim hostname
保存退出
修改etc/hosts
127.0.0.1 localhost
192.168.1.100 s100
192.168.1.101 s101
192.168.1.102 s102
192.168.1.103 s103
192.168.1.104 s104
192.168.1.105 s105
配置NAT网络
查看window10下的ip地址及网关
配置/etc/network/interfaces
#interfaces(5) file used by ifup(8) and ifdown(8)
#The loopback network interface
auto lo
iface lo inet loopback #iface eth0 inet static
iface eth0 inet static
address 192.168.1.105
netmask 255.255.255.0
gateway 192.168.1.2
dns-nameservers 192.168.1.2
auto eth0
也可以通过图形化界面配置
配置好后执行ping www.baidu.com看网络是不是已经起作用
当网络通了之后,要想客户机宿主机之前进行Ping通,只需要做以下配置
修改宿主机c:\windows\system32\drivers\etc\hosts文件
文件内容
127.0.0.1 localhost
192.168.1.100 s100
192.168.1.101 s101
192.168.1.102 s102
192.168.1.103 s103
192.168.1.104 s104
192.168.1.105 s105
安装ubuntu 163 14.04 源
$>cd /etc/apt/
$>gedit sources.list
切记在配置之前做好备份

更新
$>apt-get update
在家根目录下新建soft文件夹 mkdir soft
但是建立完成后,该文件属于root用户,修改权限 chown enmoedu:enmoedu soft/
安装共享文件夹
将该文件放到桌面,右键,点击“Extract here”
切换到enmoedu用户的家目录,cd /Desktop/vmware-tools-distrib
执行./vmware-install.pl文件
Enter键执行
安装完成
拷贝hadoop-2.7.2.tar、jdk-8u65-linux-x64.tar到enmoedu家目录下的/Downloads
$> sudo cp hadoop-2.7.2.tar.gz jdk-8u65-linux-x64.tar.gz ~/Downloads/
分别解压hadoop-2.7.2.tar、jdk-8u65-linux-x64.tar到当前目录
$> tar -zxvf hadoop-2.7.2.tar.gz
$>tar -zxvf jdk-8u65-linux-x64.tar.gz
$>cp -r hadoop-2.7.2 /soft
$>cp -r jdk1.8.0_65/ /soft
建立链接文件
$>ln -s hadoop-2.7.2/ hadoop
$>ln -s jdk1.8.0_65/ jdk
$>ls -ll
配置环境变量
$>vim /etc/environment
JAVA_HOME=/soft/jdk
HADOOP_HOME=/soft/hadoop
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/soft/jdk/bin:/soft/hadoop/bin:/soft/hadoop/sbin"
让环境变量生效
$>source environment
检验安装是否成功
$>java –version
$>hadoop version
配置/soft/hadoop/etc/hadoop/ 下的配置文件
[core-site.xml]
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://s100/</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/enmoedu/hadoop</value>
</property>
</configuration>
[hdfs-site.xml]
<configuration>
<property>
<name>dfs.replication</name>
<value>3</value>
</property>
<property>
<name>dfs.namenode.secondary.http-address</name>
<value>s104:50090</value>
<description>
The secondary namenode http server address and port.
</description>
</property>
</configuration>
[mapred-site.xml]
<configuration>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>
[yarn-site.xml]
<configuration>
<property>
<name>yarn.resourcemanager.hostname</name>
<value>s100</value>
</property>
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
</configuration>
配置ssh无密码登录
安装ssh
$>sudo apt-get install ssh
生成秘钥对
在enmoedu家目录下执行
$>ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
导入公钥数据到授权库中
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
测试localhost成功后,将master节点上的供钥拷贝到授权库中
其中root一样执行即可
$>ssh localhost
从master节点上测试是否成功。
修改slaves文件
[/soft/hadoop/etc/hadoop/slaves]
s101
s102
s103
s105
其余机器,通过克隆,修改hostname和网络配置即可
塔建完成后
格式化hdfs文件系统
$>hadoop namenode –format
启动所有进程
start-all.sh
最终结果:
自定义脚本xsync(在集群中分发文件)
[/usr/local/bin]
循环复制文件到所有节点的相同目录下。
[usr/local/bin/xsync]
#!/bin/bash
pcount=$#
if (( pcount<1 ));then
echo no args;
exit;
fi
p1=$1;
fname=`basename $p1`
#echo $fname=$fname; pdir=`cd -P $(dirname $p1) ; pwd`
#echo pdir=$pdir cuser=`whoami`
for (( host=101;host<106;host=host+1 )); do
echo ------------s$host----------------
rsync -rvl $pdir/$fname $cuser@s$host:$pdir
done
测试
xsync hello.txt
自定义脚本xcall(在所有主机上执行相同的命令)
[usr/local/bin]
#!/bin/bash
pcount=$#
if (( pcount<1 ));then
echo no args;
exit;
fi
echo -----------localhost----------------
$@
for (( host=101;host<106;host=host+1 )); do
echo ------------s$host-------------
ssh s$host $@ done
测试 xcall rm –rf hello.txt
集群搭建完成后,测试次运行以下命令
touch a.txt
gedit a.txt
hadoop fs -mkdir -p /user/enmoedu/data
hadoop fs -put a.txt /user/enmoedu/data
hadoop fs -lsr /
