本篇內容主要講解“CentOS7-64bit編譯Hadoop-2.5.0并分布式安裝的步驟”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“CentOS7-64bit編譯Hadoop-2.5.0并分布式安裝的步驟”吧!

1.系統環境說明

CentOS 7.0 x64 版本

192.168.1.7 master
192.168.1.8 slave
192.168.1.9 slave
192.168.1.10 slave

2.安裝前的準備工作

2.1 關閉防火墻

# systemctl status firewalld.service  --查看防火墻狀態
# systemctl stop firewalld.service    --關閉防火墻
# systemctl disable firewalld.service --永久關閉防火墻

2.2 檢查ssh安裝情況，如果沒有則安裝ssh

# systemctl status sshd.service  --查看ssh狀態
# yum install openssh-server openssh-clients

2.3 安裝vim

# yum -y install vim

2.4 設置靜態ip地址

# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736

BOOTPROTO="static"
ONBOOT="yes"
IPADDR0="192.168.1.7"
PREFIX0="255.255.255.0"
GATEWAY0="192.168.1.1"
DNS1="61.147.37.1"
DNS2="101.226.4.6"

2.5 修改host名稱

# vim /etc/sysconfig/network

HOSTNAME=master

# vim /etc/hosts

192.168.1.7   master
192.168.1.8   slave1
192.168.1.9   slave2
192.168.1.10  slave3

# hostnamectl set-hostname master    (CentOS7 下原有的修改host方法無效了)

2.6 創建hadoop用戶

# useradd hadoop --創建用戶名為hadoop的用戶# passwd hadoop  --為用戶hadoop設置密碼

2.7 配置ssh無密鑰登錄

-----------下面是在master上面的操作

# su hadoop --切換到hadoop用戶$ cd ~      --打開用戶文件夾
$ ssh-keygen -t rsa -P '' --生成密碼對，/home/hadoop/.ssh/id_rsa和/home/hadoop/.ssh/id_rsa.pub
$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys        --把id_rsa.pub追加到授權的key里面去
$ chmod 600 ~/.ssh/authorized_keys        --修改權限
$ su  --切換到root用戶# vim /etc/ssh/sshd_config   --修改ssh配置文件
 RSAAuthentication yes #啟用RSA認證
 PubkeyAuthentication yes #啟用公鑰私鑰配對認證方式
 AuthorizedKeysFile .ssh/authorized_keys #公鑰文件路徑
# su hadoop --切換到hadoop用戶
$ scp ~/.ssh/id_rsa.pub hadoop@192.168.1.8:~/                --把公鑰復制所有的Slave機器上

----------下面是在slave1上面的操作

 # su hadoop --切換到hadoop用戶
 $ mkdir ~/.ssh
 $ chmod 700 ~/.ssh
 $ cat ~/id_rsa.pub >> ~/.ssh/authorized_keys                --追加到授權文件"authorized_keys"
 $ chmod 600 ~/.ssh/authorized_keys                          --修改權限
 $ su --切換回root用戶 # vim /etc/ssh/sshd_config   --修改ssh配置文件
  RSAAuthentication yes #啟用RSA認證
  PubkeyAuthentication yes #啟用公鑰私鑰配對認證方式
  AuthorizedKeysFile .ssh/authorized_keys #公鑰文件路徑

3.安裝必須的軟件

3.1 安裝JDK

# rpm -ivh jdk-7u67-linux-x64.rpm

Preparing...

  ##################################### [100%]

1:jdk

  ##################################### [100%]

Unpacking JAR files...
rt.jar...
jsse.jar...
charsets.jar...
tools.jar...
localedata.jar...

# vim /etc/profile
 export JAVA_HOME=/usr/java/jdk1.7.0_67 
 export PATH=$PATH:$JAVA_HOME/bin
# source profile --修改生效

3.2 安裝其他必須軟件

# yum install maven svn ncurses-devel gcc* lzo-devel zlib-devel autoconf automake libtool cmake openssl-devel

3.3 安裝ant

# tar zxvf apache-ant-1.9.4-bin.tar.gz# vim /etc/profile
 export ANT_HOME=/usr/local/apache-ant-1.9.4
 export PATH=$PATH:$ANT_HOME/bin

3.4 安裝findbugs

# tar zxvf findbugs-3.0.0.tar.gz# vim /etc/profile
 export FINDBUGS_HOME=/usr/local/findbugs-3.0.0
 export PATH=$PATH:$FINDBUGS_HOME/bin

3.5 安裝protobuf

# tar zxvf protobuf-2.5.0.tar.gz(必須是2.5.0版本的，不然編譯hadoop的時候報錯)
# cd protobuf-2.5.0
# ./configure --prefix=/usr/local
# make && make install

4. 編譯hadoop源碼

# tar zxvf hadoop-2.5.0-src.tar.gz
# cd hadoop-2.5.0-src
# mvn package -Pdist,native,docs -DskipTests -Dtar

4.1 maven中央倉庫的配置(改成oschina,增加訪問速度)

# vim /usr/share/mavem/conf/settings.xml<mirrors>
    <mirror>
        <id>nexus-osc</id>
