Hadoop2.7.3编译安装

 

#准备3台centos7电脑。并配置无密码登录

1.安装java1.8.144

2.编译环境

yum install cmake lzo-devel zlib-devel gcc gcc-c++ autoconf automake libtool ncurses-devel openssl-devel libXtst

3.安装protobuf

下载protobuf-2.5.0，不能用高版本，否则Hadoop编译不能通过
wget https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz

tar xvf protobuf-2.5.0.tar.gz
cd protobuf-2.5.0
./configure 
make
make install
ldconfig

protoc --version

4.安装maven

wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.5.0/binaries/apache-maven-3.5.0-bin.tar.gz
tar -zxvf apache-maven-3.5.0-bin.tar.gz

vi /etc/profile
export MAVEN_HOME=/opt/apache-maven-3.5.0
export PATH=$PATH:$MAVEN_HOME/bin

在maven的settings.xml 文件里配置mirrors的子节点，添加如下mirror

<mirror>
    <id>nexus-aliyun</id>
    <mirrorOf>*</mirrorOf>
    <name>Nexus aliyun</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>

5.下载hadoop2.7.3,编译

tar -zxvf hadoop-2.7.3-src.tar.gz
mvn package -DskipTests -Pdist,native -Dtar
