hadoop2.2.0 集群安装 ubuntu12

10 March 2014

写这篇文章主要是记录一下自己的安装过程和踩下的坑 2.2.0的安装和1.x的安装前奏是一样的，jdk,免密钥登录等，可以参考1.1.0安装文章

安装：

1.下载hadoop2.2.0版本

http://apache.fayea.com/apache-mirror/hadoop/common/stable/(注意：如果你是在32位机器上安装可以下载编译好的文件hadoop-2.2.0.tar.gz，如果是64位的很不幸你需要下载源码包自己编译)

2.编译

如果你没有安装maven请先行安装并注意版本最好是3.0.5，同时jdk最好是1.6版本否则编译时会有很多问题

在编译hadoop时由于需要使用protobuf2.5和cmake

protobuf2.5安装:

tar -zxf protobuf-2.5.0.tar.gz //版本最好是2.5
cd protobuf-2.5.0
./configure --prefix=/usr   //注意：如果是ubuntu 就必须安装在/usr目录
make check
make install

cmake安装：

sudo apt-get install cmake  //ubuntu下这样安装

开始安装hadoop

解压hadoop2.2.0的压缩包，进入 hadoop-2.2.0-src

mvn package -Pdist,native -DskipTests -Dtar //执行后等待10分钟左右

编译完成后文件存放在 hadoop-2.2.0-src/hadoop-dist/target/hadoop-2.2.0.tar.gz

3.安装

将编译后的文件拷贝到服务器上解压

tar -zvxf hadoop-2.2.0.tar.gz
cd hadoop-2.2.0/etc/hadoop
