1.系统环境

[root@master ~]# uname -aLinux master 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux或者[root@master /]# cat /etc/redhat-releaseRed Hat Enterprise Linux Server release 6.4 (Santiago)

2.安装前的准备
2.1关闭防火墙

--查看防火墙状态[root@master ~]# service iptables status--停止防火墙[root@master ~]# service iptables stop--永久禁止防火墙[root@master ~]# chkconfig iptables off

2.2查看ssh是否安装

--第一种方式：[root@master ~]# which ssh/usr/bin/ssh--第二种方式[root@master ~]# service sshd statusopenssh-daemon (pid  1983) is running...--第三种方式[root@master ~]# rpm -qa openssh openssl--第四种方式(查看是否启动)[root@master ~]# ps -ef|grep ssh

2.3配置网卡

[root@master ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0DEVICE=eth0HWADDR=08:00:27:C0:18:81TYPE=EthernetUUID=8f07e2a4-702d-4e4e-a7c9-a0d4d1c9a880ONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=noneIPADDR=192.168.8.205NETMASK=255.255.255.0GATEWAY=192.168.8.1DNS1=221.228.255.1

2.4配置hosts

[root@master ~]# cat /etc/hosts127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4::1         localhost localhost.localdomain localhost6 localhost6.localdomain6--添加如下内容192.168.8.205 master192.168.8.223 slave

2.5修改hostname为master

[root@master ~]# cat /etc/sysconfig/networkNETWORKING=yesHOSTNAME=master

2.6创建hadoop用户

--创建用户[root@master ~]# useradd hadoop--配置用户密码[root@master ~]# passwd hadoop

2.7配置ssh无密码登陆

在master机器上操作

--切换hadoop用户[root@master ~]# su - hadoop--生成需要建立ssh的私钥和公钥,连续3次回车建立公钥文件(id_rsa.pub)和私钥文件(id_rsa)[hadoop@master ~]$ ssh-keygen -t rsa--把id_rsa.pub追加到授权的authorized_keys里面去[hadoop@master ~]$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys--修改权限        [hadoop@master ~]$ chmod 600 ~/.ssh/authorized_keys       --切换到root用户,修改ssh配置文件[hadoop@master ~]$ exit[root@master ~]# vim /etc/ssh/sshd_config    RSAAuthentication yes #启用RSA认证 PubkeyAuthentication yes #启用公钥私钥配对认证方式 AuthorizedKeysFile .ssh/authorized_keys #公钥文件路径

登陆到slave机器上

--切换到hadoop用户[root@slave ~]# su - hadoop --创建.ssh文件夹[hadoop@slave ~]$ mkdir ~/.ssh--切换到maste主机上的hadoop用户下[root@master ~]# su - hadoop --将密钥scp到slave机器上[hadoop@master ~]$ scp ~/.ssh/id_rsa.pub hadoop@slave:~/.ssh--切换到slave机器上的hadoop下[hadoop@slave ~]$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys--授予权限(master和slave都要授权)chmod 700 ~/.ssh/chmod 700 /home/hadoopchmod 600 ~/.ssh/authorized_keys

3.安装必须的软件
3.1安装jdk

--创建jdk目录mkdir /usr/java将下载的jdk-8u60-linux-x64.tar.gz解压到java目录下--配置jdk环境[root@master ~]# vim /etc/profileexport JAVA_HOME=/usr/java/jdk1.8.0_60export PATH=$PATH:$JAVA_HOME/bin--修改生效[root@master ~]# source profile --测试是否安装成功[hadoop@master ~]$ java -versionjava version "1.5.0"gij (GNU libgcj) version 4.4.7 20120313 (Red Hat 4.4.7-3)Copyright (C) 2007 Free Software Foundation, Inc.This is free software; see the source for copying conditions.

4.1修改maven源

[root@master local]# cd /usr/local/apache-maven/conf[root@master conf]# mv settings.xml settings.xml.bak[root@master conf]# touch settings.xml --maven中央仓库的配置(改成oschina,增加访问速度)<mirror>        <id>nexus-osc</id>        <mirrorOf>*</mirrorOf>        <name>Nexus osc</name>        <url>http://maven.oschina.net/content/groups/public/</url>    </mirror></mirrors><profiles>    <profile>    <id>jdk17</id>    <activation>        <activeByDefault>true</activeByDefault>        <jdk>1.7</jdk>    </activation>    <properties>        <maven.compiler.source>1.7</maven.compiler.source>        <maven.compiler.target>1.7</maven.compiler.target>        <maven.compiler.compilerVersion>1.7</maven.compiler.compilerVersion>    </properties>            <repositories>           <repository>                <id>nexus</id>                <name>local private nexus</name>                <url>http://maven.oschina.net/content/groups/public/</url>                <releases>                    <enabled>true</enabled>                </releases>                <snapshots>                    <enabled>false</enabled>                </snapshots>            </repository>         </repositories>        <pluginRepositories>            <pluginRepository>                <id>nexus</id>                <name>local private nexus</name>                <url>http://maven.oschina.net/content/groups/public/</url>                <releases>                    <enabled>true</enabled>                </releases>                <snapshots>                    <enabled>false</enabled>                </snapshots>            </pluginRepository>         </pluginRepositories>    </profile></profiles>

4.2 编译完后，会在目录/usr/local/hadoop-2.7.1-src/hadoop-dist/target下生成
hadoop-2.7.1和编译好的64位hadoop-2.7.1.tar.gz

[root@master conf]# cd /usr/local/hadoop-2.7.1-src/hadoop-dist/target[root@master target]# lltotal 844744drwxr-xr-x. 2 root root      4096 Sep 11 11:25 antrun-rw-r--r--. 1 root root      1867 Sep 11 11:25 dist-layout-stitching.sh-rw-r--r--. 1 root root       640 Sep 11 11:26 dist-tar-stitching.shdrwxr-xr-x. 9 root root      4096 Sep 11 11:25 hadoop-2.7.1-rw-r--r--. 1 root root 285910336 Sep 11 11:27 hadoop-2.7.1.tar.gz-rw-r--r--. 1 root root      2823 Sep 11 11:26 hadoop-dist-2.7.1.jar-rw-r--r--. 1 root root 579067602 Sep 11 11:29 hadoop-dist-2.7.1-javadoc.jardrwxr-xr-x. 2 root root      4096 Sep 11 11:28 javadoc-bundle-optionsdrwxr-xr-x. 2 root root      4096 Sep 11 11:26 maven-archiverdrwxr-xr-x. 2 root root      4096 Sep 11 11:25 test-dir
