hadoop的編譯和安裝是直接在一臺機器上搞得，姑且nn1機器。

全程切換到root用戶下操做

1.hadoop的一些資源在這裏：https://www.lanzous.com/b849710/   密碼:9vui

[hadoop@nn1 zk_op]$ su - root
[root@nn1 ~]# mkdir /tmp/hadoop_c
[root@nn1 ~]# cd /tmp/hadoop_c/
用xshell的rz命令上傳源碼包到上面的目錄。
[root@nn1 hadoop_c]# tar -xzf /tmp/hadoop_c/hadoop-2.7.3-src.tar.gz -C /usr/local/

yum安裝一下亂七八糟要用到的軟件和插件

yum -y install svn ncurses-devel gcc* lzo-devel zlib-devel autoconf automake libtool cmake openssl-devel bzip2

2.編譯安裝protobuf，谷歌的通訊和存儲協議，必需要用

[root@nn1 ~]# tar -zxf protobuf-2.5.0.tar.gz -C /usr/local/
[root@nn1 ~]# cd /usr/local/protobuf-2.5.0
進行編譯安裝
[root@nn1 protobuf-2.5.0]# ./configure
[root@nn1 protobuf-2.5.0]# make && make install
[root@nn1 protobuf-2.5.0]# protoc --version

3.解壓安裝ant

[root@nn1 hadoop_c]# tar -xf apache-ant-1.9.9-bin.tar.bz2 -C /usr/local/

4.解壓安裝findbugs

[root@nn1 hadoop_c]# tar -zxf apache-ant-1.9.9-bin.tar.bz2 -C /usr/local/

5.解壓安裝maven

由於咱的hadoop在後邊是用maven編譯的。

[root@nn1 hadoop_c]# tar -zxf apache-maven-3.3.9-bin.tar.gz -C /usr/local/

6.編譯安裝snappy，谷歌的壓縮算法

[root@nn1 hadoop_c]# tar -xzf snappy-1.1.3.tar.gz -C /usr/local/
[root@nn1 hadoop_c]# cd /usr/local/snappy-1.1.3/
[root@nn1 snappy-1.1.3]# ./configure
[root@nn1 snappy-1.1.3]# make && make install

7.確保已經安裝jdk8

8.在環境變量中添加hadoop編譯所需的各類軟件的變量

[root@nn1 snappy-1.1.3]# vim /etc/profile
#set Hadoop_compile
export MAVEN_HOME=/usr/local/apache-maven-3.3.9
export FINDBUGS_HOME=/usr/local/findbugs-3.0.1
export PROTOBUF_HOME=/usr/local/protobuf-2.5.0
export ANT_HOME=/usr/local/apache-ant-1.9.9
export PATH=$PATH:$MAVEN_HOME/bin:$FINDBUGS_HOME/bin:$ANT_HOME/bin
export MAVEN_OPTS="-Xmx2g -XX:MaxMetaspaceSize=512M -XX:ReservedCodeCacheSize=512m"

讓環境變量生效：
[root@nn1 snappy-1.1.3]# source /etc/profile
查看maven版本
[root@nn1 snappy-1.1.3]# mvn -v
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00)
Maven home: /usr/local/apache-maven-3.3.9
Java version: 1.8.0_144, vendor: Oracle Corporation
Java home: /usr/java/jdk1.8.0_144/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-957.21.3.el7.x86_64", arch: "amd64", family: "unix"
[root@nn1 snappy-1.1.3]#

9.更改maven的settings.xml文件，更改倉庫，配置本地倉庫位置

[root@nn1 hadoop_c]# cd /usr/local/apache-maven-3.3.9/conf/
[root@nn1 conf]# cp settings.xml settings.xml.bak
[root@nn1 conf]# rm -rf settings.xml
[root@nn1 conf]# cp /tmp/hadoop_c/settings.xml settings.xml

能夠直接用上邊網盤裏弄好的配置文件
主要修改了：
<!-- 本地倉庫 -->
  <localRepository>/data/maven/repositories</localRepository>
和遠程倉庫
<mirror>
      <id>huaweicloud</id>
      <mirrorOf>central</mirrorOf>
      <url>https://repo.huaweicloud.com/repository/maven/</url>
    </mirror>
    <mirror>
    	<id>nexus-aliyun</id>
		  <mirrorOf>central</mirrorOf>
		  <name>Nexus aliyun</name>
		  <url>http://maven.aliyun.com/nexus/content/groups/public</url>
	  </mirror>
    <mirror>        
      <id>maven</id>        
      <name>MavenMirror</name>        
      <url>http://repo1.maven.org/maven2/</url>        
      <mirrorOf>central</mirrorOf>        
   </mirror>

把網盤裏的maven離線倉庫下載解壓成以下路徑/data/maven/repositories/各類jar包

下邊開始用maven編譯hadoop源碼

[root@nn1 conf]# cd /usr/local/hadoop-2.7.3-src/
[root@nn1 hadoop-2.7.3-src]# nohup mvn clean package -Pdist,native -DskipTests -Dtar -Dbundle.snappy -Dsnappy.lib=/usr/local/lib > /tmp/hadoop_log 2>&1 &

nohup命令用來讓任務在後臺運行，這裏重定向輸出到了日誌文件，這裏經過查看日誌文件來監控安裝進程。

[root@nn1 hadoop-2.7.3-src]# tail -f /tmp/hadoop_log

10.編譯完成後就會在/usr/local/hadoop-2.7.3-src/hadoop-dist/target/下生成一個tar.gz的包，把這個包cp到咱們的home，而後批量發送給其餘4臺機器。

[root@nn1 ~]# exit
登出
[hadoop@nn1 ~]$ cp /usr/local/hadoop-2.7.3-src/hadoop-dist/target/hadoop-2.7.3.tar.gz ~/
[hadoop@nn1 hadoop_base_op]$ ./scp_all.sh ../hadoop-2.7.3.tar.gz /tmp/

11.把5臺機器的tar包批量解壓到各自的/usr/local/下

[hadoop@nn1 hadoop_base_op]$ ./ssh_root.sh tar -zxf /tmp/hadoop-2.7.3.tar.gz -C /usr/local/
修改文件用戶和權限
[hadoop@nn1 hadoop_base_op]$ ./ssh_all.sh chmod -R 770 /usr/local/hadoop-2.7.3
[hadoop@nn1 hadoop_base_op]$ ./ssh_root.sh ln -s /usr/local/hadoop-2.7.3 /usr/local/hadoop

這時候hadoop就安裝結束了，檢查一下是否正確安裝

[hadoop@s1 ~]$ source /etc/profile
[hadoop@s1 ~]$ hadoop checknative
19/07/22 15:37:25 INFO bzip2.Bzip2Factory: Successfully loaded & initialized native-bzip2 library system-native
19/07/22 15:37:25 INFO zlib.ZlibFactory: Successfully loaded & initialized native-zlib library
Native library checking:
hadoop:  true /usr/local/hadoop-2.7.3/lib/native/libhadoop.so.1.0.0
zlib:    true /usr/lib64/libz.so.1

lz4:     true revision:99
bzip2:   true /usr/lib64/libbz2.so.1
openssl: true /usr/lib64/libcrypto.so

若是提示hadoop是未知命令，那麼就要查看環境變量是否正確配置，而後能夠從新source一下環境變量。
