本文记录一下在CentOS 6.7上，安装Hadoop-2.7.3版本的过程。

安装Hadoop主要包含如下几个部分：

安装JDK

安装Hadoop

配置Hadoop

启动Hadoop

验证Hadoop

安装JDK

安装JDK可以参考如下博文，这里就不再重复描述。

安装Hadoop

创建hadoop账户

[root@dev03 srv]# useradd hadoop[root@dev03 srv]# passwd hadoopChanging password for user hadoop.New password: BAD PASSWORD: it is based on a dictionary wordBAD PASSWORD: is too simpleRetype new password: passwd: all authentication tokens updated successfully.[root@dev03 srv]#

为hadoop用户配置SSH KEY。

[root@dev03 srv]# su - hadoop[hadoop@dev03 ~]$

ssh-keygen -t rsa

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 0600 ~/.ssh/authorized_keys

[hadoop@dev03 ~]$ ssh-keygen -t rsaGenerating public/private rsa key pair.Enter file in which to save the key (/home/hadoop/.ssh/id_rsa): Created directory '/home/hadoop/.ssh'.Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/hadoop/.ssh/id_rsa.Your public key has been saved in /home/hadoop/.ssh/id_rsa.pub.The key fingerprint is:23:27:78:a5:73:a6:3f:b0:1a:b6:87:00:d4:9e:26:67 hadoop@dev03.gzhl.interconnectThe key's randomart image is:+--[ RSA 2048]----+|  .              || . .             ||. . .   .        ||..

下载Hadoop安装包

使用 wget 命令下载hadoop-2.7.3.tar.gz，如:

[root@dev03 srv]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/hadoop-2.7.3/hadoop-2.7.3.tar.gz--2017-01-24 13:54:44--  http://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/hadoop-2.7.3/hadoop-2.7.3.tar.gzResolving mirrors.tuna.tsinghua.edu.cn... 166.111.206.178, 2402:f000:1:416:166:111:206:178Connecting to mirrors.tuna.tsinghua.edu.cn|166.111.206.178|:80... connected.HTTP request sent, awaiting response... 200 OKLength: 214092195 (204M) [application/octet-stream]Saving to: “hadoop-2.7.3.tar.gz”100%[====================================================================================================================================================================================================================================>] 214,092,195 22.0M/s   in 9.6s    2017-01-24 13:54:53 (21.2 MB/s) - “hadoop-2.7.3.tar.gz” saved [214092195/214092195][root@dev03 srv]#

解压hadoop-2.7.3.tar.gz

使用tar -zvxf hadoop-2.7.3.tar.gz 解压，并修改解压后的hadoop目录名。

[root@dev03 srv]# tar -zvxf hadoop-2.7.3.tar.gz ... ... hadoop-2.7.3/share/hadoop/tools/lib/asm-3.2.jarhadoop-2.7.3/include/hadoop-2.7.3/include/hdfs.hhadoop-2.7.3/include/Pipes.hhhadoop-2.7.3/include/TemplateFactory.hhhadoop-2.7.3/include/StringUtils.hhhadoop-2.7.3/include/SerialUtils.hhhadoop-2.7.3/LICENSE.txthadoop-2.7.3/NOTICE.txthadoop-2.7.3/README.txt[root@dev03 srv]# mv hadoop-2.7.3 hadoop[root@dev03 srv]#

进入hadoop目录，可以看到有如下内容：

[root@dev03 srv]# cd hadoop[root@dev03 hadoop-2.7.3]# lltotal 132drwxr-xr-x 2 root root  4096 Aug 18 09:49 bindrwxr-xr-x 3 root root  4096 Aug 18 09:49 etcdrwxr-xr-x 2 root root  4096 Aug 18 09:49 includedrwxr-xr-x 3 root root  4096 Aug 18 09:49 libdrwxr-xr-x 2 root root  4096 Aug 18 09:49 libexec-rw-r--r-- 1 root root 84854 Aug 18 09:49 LICENSE.txt-rw-r--r-- 1 root root 14978 Aug 18 09:49 NOTICE.txt-rw-r--r-- 1 root root  1366 Aug 18 09:49 README.txtdrwxr-xr-x 2 root root  4096 Aug 18 09:49 sbindrwxr-xr-x 4 root root  4096 Aug 18 09:49 share[root@dev03 hadoop-2.7.3]#

配置Hadoop环境变量

解压完hadoop之后，需要配置hadoop相关的环境变量，如HADOOP_HOME。

设置环境变量

使用vim /etc/profile打开环境配置文件，在最后添加如下内容，其中JAVA_HOME和HADOOP_HOME的路径由对应的安装目录决定。

export JAVA_HOME=/usr/java/jdk1.7.0_71export PATH=PATH=$PATH:$JAVA_HOME/binexport HADOOP_HOME=/srv/hadoopexport HADOOP_INSTALL=$HADOOP_HOMEexport HADOOP_MAPRED_HOME=$HADOOP_HOMEexport HADOOP_COMMON_HOME=$HADOOP_HOMEexport HADOOP_HDFS_HOME=$HADOOP_HOMEexport HADOOP_YARN_HOME=$HADOOP_HOMEexport HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/nativeexport PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin

使用source /etc/profile命令，使新添加的环境变量生效。

[root@dev03 srv]# vim /etc/profile[root@dev03 srv]# source /etc/profile[root@dev03 srv]#

配置好相关的环境变量后，进入到<HADOOP_HOME>/etc/hadoop目录下，修改相关配置文件的信息。<HADOOP_HOME>/etc/hadoop目录下的配置文件如下：

[root@dev03 hadoop]# cd etc/hadoop/[root@dev03 hadoop]# lltotal 152-rw-r--r-- 1 root root  4436 Aug 18 09:49 capacity-scheduler.xml-rw-r--r-- 1 root root  1335 Aug 18 09:49 configuration.xsl-rw-r--r-- 1 root root   318 Aug 18 09:49 container-executor.cfg-rw-r--r-- 1 root root   774 Aug 18 09:49 core-site.xml-rw-r--r-- 1 root root  3589 Aug 18 09:49 hadoop-env.cmd-rw-r--r-- 1 root root  4224 Aug 18 09:49 hadoop-env.sh-rw-r--r-- 1 root root  2598 Aug 18 09:49 hadoop-metrics2.properties-rw-r--r-- 1 root root  2490 Aug 18 09:49 hadoop-metrics.properties-rw-r--r-- 1 root root  9683 Aug 18 09:49 hadoop-policy.xml-rw-r--r-- 1 root root   775 Aug 18 09:49 hdfs-site.xml-rw-r--r-- 1 root root  1449 Aug 18 09:49 httpfs-env.sh-rw-r--r-- 1 root root  1657 Aug 18 09:49 httpfs-log4j.properties-rw-r--r-- 1 root root    21 Aug 18 09:49 httpfs-signature.secret-rw-r--r-- 1 root root   620 Aug 18 09:49 httpfs-site.xml-rw-r--r-- 1 root root  3518 Aug 18 09:49 kms-acls.xml-rw-r--r-- 1 root root  1527 Aug 18 09:49 kms-env.sh-rw-r--r-- 1 root root  1631 Aug 18 09:49 kms-log4j.properties-rw-r--r-- 1 root root  5511 Aug 18 09:49 kms-site.xml-rw-r--r-- 1 root root 11237 Aug 18 09:49 log4j.properties-rw-r--r-- 1 root root   931 Aug 18 09:49 mapred-env.cmd-rw-r--r-- 1 root root  1383 Aug 18 09:49 mapred-env.sh-rw-r--r-- 1 root root  4113 Aug 18 09:49 mapred-queues.xml.template-rw-r--r-- 1 root root   758 Aug 18 09:49 mapred-site.xml.template-rw-r--r-- 1 root root    10 Aug 18 09:49 slaves-rw-r--r-- 1 root root  2316 Aug 18 09:49 ssl-client.xml.example-rw-r--r-- 1 root root  2268 Aug 18 09:49 ssl-server.xml.example-rw-r--r-- 1 root root  2191 Aug 18 09:49 yarn-env.cmd-rw-r--r-- 1 root root  4567 Aug 18 09:49 yarn-env.sh-rw-r--r-- 1 root root   690 Aug 18 09:49 yarn-site.xml[root@dev03 hadoop]#

修改core-site.xml


    
       
      
       fs.default.name
          
      
       hdfs://localhost:9000

如：

修改hdfs-site.xml

修改hdfs-site.xml内容之前，先创建namenode和datanode的文件夹，如

<HADOOP_HOME>/hadoopdata/hdfs/namenode

<HADOOP_HOME>/hadoopdata/hdfs/datanode

[root@dev03 hadoop]# mkdir hadoopdata[root@dev03 hadoop]# cd hadoopdata/[root@dev03 hadoopdata]# mkdir hdfs[root@dev03 hadoopdata]# cd hdfs[root@dev03 hdfs]# mkdir namenode[root@dev03 hdfs]# mkdir datanode[root@dev03 hdfs]# lltotal 8drwxr-xr-x 2 root root 4096 Jan 24 14:42 datanodedrwxr-xr-x 2 root root 4096 Jan 24 14:42 namenode[root@dev03 hdfs]#

修改hdfs-site.xml，如：


    
    
      
      
       dfs.replication
       
      
       1
      
     
       
      
       dfs.name.dir
          
      
       file:///srv/hadoop/hadoopdata/hdfs/namenode
      
     
       
      
       dfs.data.dir
          
      
       file:///srv/hadoop/hadoopdata/hdfs/datanode

修改yarn-site.xml


    
     
       
      
       yarn.nodemanager.aux-services
          
      
       mapreduce_shuffle

修改hadoop-env.sh

修改hadoop-env.sh中的JAVA_HOME，与安装的路径匹配，如：

#export JAVA_HOME=${JAVA_HOME}export JAVA_HOME=/usr/java/jdk1.7.0_71

格式化namenode

可以使用hdfs namenode -format命令格式化namenode。

[root@dev03 hadoop]# hdfs namenode -format17/01/24 14:52:03 INFO namenode.NameNode: STARTUP_MSG: /************************************************************STARTUP_MSG: Starting NameNodeSTARTUP_MSG:

启动hadoop

配置好hadoop的环境变量和文件之后，就可以启动hadoop。

使用start-dfs.sh和start-yarn.sh命令启动。

start-dfs.sh

[root@dev03 sbin]# start-dfs.sh17/01/24 15:20:40 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicableStarting namenodes on [localhost]root@localhost's password: localhost: starting namenode, logging to /srv/hadoop/logs/hadoop-root-namenode-dev03.gzhl.interconnect.outroot@localhost's password: localhost: starting datanode, logging to /srv/hadoop/logs/hadoop-root-datanode-dev03.gzhl.interconnect.outStarting secondary namenodes [0.0.0.0]root@0.0.0.0's password: 0.0.0.0: starting secondarynamenode, logging to /srv/hadoop/logs/hadoop-root-secondarynamenode-dev03.gzhl.interconnect.out17/01/24 15:22:34 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable[root@dev03 sbin]#

使用start-dfs.sh命令启动时，需要输入root@localhost的密码。

start-yarn.sh

[root@dev03 sbin]# start-yarn.shstarting yarn daemonsresourcemanager running as process 13318. Stop it first.root@localhost's password: localhost: nodemanager running as process 13588. Stop it first.[root@dev03 sbin]#

同样，使用start-yarn.sh命令启动时，需要输入root@localhost的密码。

验证Hadoop

启动后，咱们就可以来验证一下hadoop是否已经启动成功。

使用jps来查看所有启动的服务，从下图可以看出NameNode、NodeManager、SecondaryNameNode等都已经启动。

[root@dev03 sbin]# jps13823 NameNode13588 NodeManager21983 Bootstrap13941 DataNode13318 ResourceManager14097 SecondaryNameNode14349 Jps[root@dev03 sbin]#

可以通过http://<安装Hadoop的IP>:50070/在浏览器查看Hadoop信息。

可以通过http://<安装Hadoop的IP>:8088/在浏览器查看所有的应用信息。

至此，可以看出Hadoop基本安装成功。
