环境

系统：Ubuntu 14.04

hadoop版本：2.6.0

hbase版本：1.0

jdk版本：1.8

下载地址：Apache上慢慢找吧~~

hadoop安装

1.安装位置：/opt

2.创建hadoop用户组

sudo addgroup hadoop

3.创建hadoop用户

sudo adduser -ingroup hadoop hadoop

4.给hadoop添加权限

sudo vim /etc/sudoers

在root ALL=(ALL:ALL) ALL下添加

hadoop  ALL=(ALL:ALL)   ALL

5.安装ssh

sudo apt-get install ssh openssh-server

6.建立ssh无密码登陆

su - hadoop
ssh-keygen -t rsa -P ""
cd ~/.ssh
cat id_rsa.pub >> authorized_keys

测试

ssh localhost

7.解压hadoop

tar -zxvf hadoop-2.6.0.tar.gz
sudo mv hadoop-2.6.0 /opt/hadoop
sudo chmod -R 775 /opt/hadoop
sudo chown -R hadoop:hadoop /opt/hadoop

8.配置环境变量

sudo vim ~/.bashrc

在末尾添加

#HADOOP VARIABLES START
export JAVA_HOME=/opt/jdk1.8.0
export HADOOP_HOME=/opt/hadoop
export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path-$HADOOP_HOME/lib"
#HADOOP VARIABLES END

export HBASE_HOME=/opt/hbase
export PATH=$PATH:$HBASE_HOME/bin
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.${JAVA_HOME}/lib:${JRE_HOME}/lib:${HADOOP_HOME}/share/hadoop/common/lib:${HBASE_HOME}/lib

source ~/.bashrc

9.修改hadoop-env.sh

将JAVA_HOME修改为jdk安装目录，这里是/opt/jdk1.8.0

10.修改core-site.xml

<configuration>
        <property>
                <name>fs.defaultFS</name>
                <value>hdfs://localhost:9000</value>
        </property>
        <property>
                <name>hadoop.tmp.dir</name>
                <value>/opt/hadoop/tmp</value>
        </property>
</configuration>

11.修改mapred-site.xml.template并修改为mapred-site.xml

<configuration>
        <property>
                <name>mapreduce.framework.name</name>
                <value>yarn</value>
        </property>
</configuration>

12.修改yarn-site.xml

<configuration>

<!-- Site specific YARN configuration properties -->
        <property>
                <name>yarn.nodemanager.aux-services</name>
                <value>mapreduce_shuffle</value>
        </property>
</configuration>

13.修改hdfs-site.xml

<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
    <property>
        <name>dfs.namenode.name.dir</name>
        <value>/opt/hadoop/dfs/name</value>
    </property>
    <property>
        <name>dfs.datanode.data.dir</name>
        <value>/opt/hadoop/dfs/data</value>
    </property>
    <property>
        <name>dfs.permissions</name>
        <value>false</value>
     </property>
</configuration>

14.修改masters和slaves

masters好像不存在，自行添加

插入：

localhost

15.添加临时目录

cd /opt/hadoop
mkdir tmp dfs dfs/name dfs/data 

16.初始化hdfs

hdfs namenode -format

17.启动hadoop

start-dfs.sh
start-yarn.sh

hbase安装

hbase安装相对简单，就是把其整合hadoop

1.解压

tar -zxvf hbase-1.0.0-bin.tar.gz
sudo mv hbase-1.0.0 /opt/hbase
cd /opt
sudo chmod -R 775 hbase
sudo chown -R hadoop:hadoop: hbase

2.修改环境变量

sudo vim /opt/hbase/conf/hbase-env.sh

修改$JAVA_HOME为jdk安装目录，这里是/opt/jdk1.8.0

3.修改hbase-site.xml

添加：

<configuration>
        <property>
                <name>hbase.rootdir</name>
                <value>hdfs://localhost:9000/hbase</value>
        </property>
        <property>
                <name>hbase.cluster.distributed</name>
                <value>true</value>
        </property>
</configuration>

4.启动hbase

start-hbase.sh

5.进入hbase shell

hbase shell

6.查看进程

通过jps，应该会看到一共有9个进程，分别如下：

3616 NodeManager
3008 NameNode
6945 HQuorumPeer
7010 HMaster
3302 SecondaryNameNode
3128 DataNode
7128 HRegionServer
3496 ResourceManager
7209 Jps

进程号不一定是这些
