JDK、Hadoop、Hive官网下载，Hive默认（嵌入式derby 模式）  
[http://hadoop.apache.org/releases.html][http_hadoop.apache.org_releases.html]  
[http://www.apache.org/dyn/closer.cgi/hive/][http_www.apache.org_dyn_closer.cgi_hive]  
[http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html][http_www.oracle.com_technetwork_java_javase_downloads_jdk8-downloads-2133151.html]  
参考文档  
[http://www.powerxing.com/install-hadoop/][http_www.powerxing.com_install-hadoop]  
创建用户和组，设置密码

root@hive:~# useradd -m hadoop -s /bin/bash
    root@hive:~# passwd hadoop
    Enter new UNIX password: 
    Retype new UNIX password: 
    passwd: password updated successfully

切换hadoop用户后，配置SSH免密登录

root@hive:~# su hadoop
    hadoop@hive:/root$ cd 
    hadoop@hive:~$ ssh-keygen -t rsa -P '' 
    #密钥默认存放在/home/hadoop/.ssh/目录下
    hadoop@hive:~$ cat ./.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
    hadoop@hive:~$ chmod 0600 !$ chmod 0600 ~/.ssh/authorized_keys

配置Java环境

hadoop@hive:~# tar xvf jdk-8u111-linux-x64.tar.gz -C /usr/share/java/
    hadoop@hive:~# vim .bash_profile
    hadoop@hive:~# cat !$
    cat .bash_profile
    export JAVA_HOME=/usr/share/java/jdk1.8.0_111/
    export PATH=$PATH:$JAVA_HOME/bin
    hadoop@hive:~# source !$
    source .bash_profile
    hadoop@hive:~# java -version
    java version "1.8.0_111"
    Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
    Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)

**Hadoop配置**  
core-site.xml：包括HDFS、MapReduce的I/O以及namenode节点的url（协议、主机名、端口）等核心配置，datanode在namenode上注册后，通过此url跟client交互

hadoop@hive:~$ vim hadoop-2.7.3/etc/hadoop/core-site.xml 
    <configuration>
            <property>
                 <name>fs.defaultFS</name>
                 <value>hdfs://localhost:9000</value>
            </property>
    </configuration>

hdfs-site.xml： HDFS守护进程配置，包括namenode，secondary namenode，datanode

hadoop@hive:~$ vim hadoop-2.7.3/etc/hadoop/hdfs-site.xml 
    <configuration>
            <property>
                 <name>dfs.replication</name>
                 <value>1</value>
            </property>
    </configuration>

mapred-site.xml：MapReduce守护进程配置，包括jobtracker和tasktrackers

hadoop@hive:~$ vim hadoop-2.7.3/etc/hadoop/mapred-site.xml
    <configuration>
            <property>
                 <name>mapreduce.framework.name</name>
                 <value>yarn</value>
            </property>
    </configuration>

全局资源管理配置  
[http://www.cnblogs.com/gw811/p/4077318.html][http_www.cnblogs.com_gw811_p_4077318.html]

hadoop@hive:~$ vim hadoop-2.7.3/etc/hadoop/yarn-site.xml 
    <configuration>
       <property>
          <name>yarn.nodemanager.aux-services</name> 
          <value>mapreduce_suffle</value>
       </property> 
    </configuration>

配置与hadoop运行环境相关的变量

hadoop@hive:~$ vim hadoop-2.7.3/etc/hadoop/hadoop-env.sh
    export JAVA_HOME=/usr/share/java/jdk1.8.0_111/

nameNode 格式化并启动，如果修改了hostname，/etc/hosts文件也需要添加本地解析，否则初始化会报错namenode unknown

hadoop@hive:~$ hadoop-2.7.3/bin/hdfs namenode -format
    hadoop@hive:~$ hadoop-2.7.3/sbin/start-dfs.sh 
    Starting namenodes on [localhost]
    localhost: starting namenode, logging to /home/hadoop/hadoop-2.7.3/logs/hadoop-hadoop-namenode-hive.out
    localhost: starting datanode, logging to /home/hadoop/hadoop-2.7.3/logs/hadoop-hadoop-datanode-hive.out
    Starting secondary namenodes [0.0.0.0]
    0.0.0.0: starting secondarynamenode, logging to /home/hadoop/hadoop-2.7.3/logs/hadoop-hadoop-secondarynamenode-hive.out

成功启动后，可访问web界面查看nameNode和datanode信息以及HDFS中的文件。  
![这里写图片描述][20161129095700542]  
伪分布式启动 YARN为可选操作，启动后可以通过web界面查看任务运行情况

hadoop@hive:~$ hadoop-2.7.3/sbin/start-yarn.sh 
    starting yarn daemons
    starting resourcemanager, logging to /home/hadoop/hadoop-2.7.3/logs/yarn-hadoop-resourcemanager-hive.out
    localhost: starting nodemanager, logging to /home/hadoop/hadoop-2.7.3/logs/yarn-hadoop-nodemanager-hive.out
    root@hive:/home/hadoop# jps
    5366 ResourceManager
    5014 DataNode
    4904 NameNode
    7354 Jps
    5214 SecondaryNameNode
    7055 RunJar

解压Hive安装包，配置运行环境变量

hadoop@hive:~$ tar xvf apache-hive-2.1.0-bin.tar.gz
    hadoop@hive:~$ tail -3 .bash_profile 
    export HADDOP_HOME=/home/hadoop/hadoop-2.7.3/
    export HIVE_HOME=/home/hadoop/apache-hive-2.1.0-bin/
    export PATH=$PATH:$HADDOP_HOME/bin:$HADDOP_HOME/bin:$HIVE_HOME/bin
    hadoop@hive:~$ source !$ source .bash_profile

HDFS上创建目录并设置权限

hadoop@hive:~$ hadoop fs -mkdir -p /tmp
    hadoop@hive:~$ hadoop fs -mkdir -p /user/hive/warehouse
    hadoop@hive:~$ hadoop fs -chmod g+w /tmp
    hadoop@hive:~$ hadoop fs -chmod g+w /user/hive/warehouse

初始化数据库

hadoop@hive:~$ schematool -dbType derby -initSchema
    SLF4J: Class path contains multiple SLF4J bindings.
    ..........
    Starting metastore schema initialization to 2.1.0
    Initialization script hive-schema-2.1.0.derby.sql
    Initialization script completed
