Hadoop编译步骤：
1.解压Hadoop源码包
[root@hadoop000 ~]# mkdir -p /opt/sourcecode [root@hadoop000 ~]# mkdir -p /opt/software [root@hadoop000 sourcecode]# cd /opt/sourcecode # 将hadoop-2.8.1-src.tar.gz下载（或者用rz上传）到sourcecode目录 [root@hadoop000 sourcecode]# ll total 33756 -rw-r--r--. 1 root root 34523353 Aug 20 12:14 hadoop-2.8.1-src.tar.gz # 解压 [root@hadoop000 sourcecode]# tar -xzvf hadoop-2.8.1-src.tar.gz [root@hadoop000 sourcecode]# ll total 33760 drwxr-xr-x. 17 root root 4096 Jun 2 14:13 hadoop-2.8.1-src -rw-r--r--. 1 root root 34523353 Aug 20 12:14 hadoop-2.8.1-src.tar.gz [root@hadoop000 sourcecode]# cd hadoop-2.8.1-src
2.JAVA安装
[root@hadoop000 ~]# mkdir -p /usr/java [root@hadoop000 ~]# cd /usr/java [root@hadoop000 java]# rz #上传jdk-8u45-linux-x64.gz [root@hadoop000 java]# tar -xzvf jdk-8u45-linux-x64.gz # 设置环境变量 [root@hadoop000 java]# vi /etc/profile # 在最底下加入 export JAVA_HOME=/usr/java/jdk1.8.0_45 export PATH=$JAVA_HOME/bin:$PATH # 生效 [root@hadoop000 java]# source /etc/profile
3.Maven安装
[root@hadoop000 ~]# cd /opt/software/ [root@hadoop000 software]# rz #上传apache-maven-3.3.9-bin.zip [root@hadoop000 software]# ll total 8432 -rw-r--r--. 1 root root 8617253 Aug 20 12:35 apache-maven-3.3.9-bin.zip # 解压 [root@hadoop000 software]# unzip apache-maven-3.3.9-bin.zip # 设置环境变量 [root@hadoop000 software]# vi /etc/profile export MAVEN_HOME=/opt/software/apache-maven-3.3.9 export MAVEN_OPTS="-Xms256m -Xmx512m" export PATH=$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH # 生效 [root@hadoop000 software]# source /etc/profile # 查看 [root@hadoop000 software]# mvn -version Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T00:41:47+08:00) Maven home: /opt/software/apache-maven-3.3.9 Java version: 1.8.0_45, vendor: Oracle Corporation Java home: /usr/java/jdk1.8.0_45/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "2.6.32-431.el6.x86_64", arch: "amd64", family: "unix"
4.Findbugs安装
[root@hadoop000 ~]# cd /opt/software/ [root@hadoop000 software]# rz #上传findbugs-1.3.9.zip # 解压 [root@hadoop000 software]# unzip findbugs-1.3.9.zip # 设置环境变量 [root@hadoop000 software]# vi /etc/profile export FINDBUGS_HOME=/opt/software/findbugs-1.3.9 export PATH=$FINDBUGS_HOME/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH # 生效 [root@hadoop000 software]# source /etc/profile # 查看 [root@hadoop000 software]# findbugs -version 1.3.9
5.protobuf安装
[root@hadoop000 ~]# cd /opt/software/ [root@hadoop000 software]# rz #上传protobuf-2.5.0.tar.gz # 解压 [root@hadoop000 software]# tar -xzvf protobuf-2.5.0.tar.gz [root@hadoop000 software]# cd protobuf-2.5.0 [root@hadoop000 protobuf-2.5.0]# yum install -y gcc gcc-c++ make cmake [root@hadoop000 protobuf-2.5.0]# ./configure --prefix=/usr/local/protobuf [root@hadoop000 protobuf-2.5.0]# make && make install # 设置环境变量 [root@hadoop000 java]# vi /etc/profile export PROTOC_HOME=/usr/local/protobuf export PATH=$PROTOC_HOME/bin:$FINDBUGS_HOME/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH # 生效 [root@hadoop000 protobuf-2.5.0]# source /etc/profile # 查看 [root@hadoop000 protobuf-2.5.0]# protoc --version libprotoc 2.5.0
6.安装其他依赖
yum install -y openssl openssl-devel svn ncurses-devel zlib-devel libtool yum install -y snappy snappy-devel bzip2 bzip2-devel lzo lzo-devel lzop autoconf automake
7.编译
[root@hadoop000 sourcecode]# cd hadoop-2.8.1-src [root@hadoop000 hadoop-2.8.1-src]# mvn clean package -Pdist,native -DskipTests -Dtar #稍等一段时间 出现以下信息即编译完成 [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 13:38 min [INFO] Finished at: 2018-05-16T15:18:47+08:00 [INFO] Final Memory: 173M/478M [INFO] ------------------------------------------------------------------------
