CentOS6.5编译部署64位Hadoop2.2.0

1 root用户，建立haoop用户

useradd -g root hadoop

2 编译hadoop（64位hadoop需要自己编译）

2.1 下载jdk、maven、hadoop-src

http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

http://maven.apache.org/download.cgi

http://mirrors.hust.edu.cn/apache/hadoop/common/

2.2 配置环境变量

sudo vim /etc/profile
JAVA_HOME=/usr/local/jdk1.7.0_25
JRE_HOME=$JAVA_HOME/jre
CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
MAVEN_HOME=/usr/local/apache-maven-3.2.2
PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$MAVEN_HOME/bin:$PATH
export JAVA_HOME JRE_HOMECLASSPATH MAVEN_HOME PATH

2.3 maven配置

2.4 安装依赖

yum install gcc
yum intall gcc-c++
yum install make

https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz

tar -xvf protobuf-2.5.0.tar.bz2
cd protobuf-2.5.0
./configure --prefix=/usr/local/protoc/
make && make install

将/usr/local/protoc/bin加入 path。

yum install cmake
yum install openssl-devel
yum install ncurses-devel

2.5 编译

打上Patch :https://issues.apache.org/jira/browse/HADOOP-10110

cd hadoop-2.2.0-src
mvn package -Pdist,native -DskipTests -Dtar

编译后的路径在:hadoop-2.2.0-src/hadoop-dist/target/hadoop-2.2.0

3 root用户，关闭防火墙

chkconfig iptables off #重启后永久性生效
service iptables stop #即时生效，重启后失效
service iptables status #查看防火墙状态

4 root用户，hosts配置

192.168.101.128 master
192.168.101.129 slave1
192.168.101.130 slave2
192.168.101.131 slave3
ifconfig eth2192.168.101.130 netmask 255.255.255.0 #设置ip

5 hadoop用户，ssh免登陆

ssh-keygen -t rsa
cd .ssh
cat id_rsa.pub >authorized_keys
#如果autorized_keys是新创建的，要更改权限为600：
chmod 600 authorized_keys
#如果其他机器是克隆机，就不必执行下面的拷贝：
scp .ssh/authorized_keys hadoop@192.168.101.129:/home/hadoop/.ssh/
scp .ssh/authorized_keyshadoop@192.168.101.130:/home/hadoop/.ssh/
scp .ssh/authorized_keyshadoop@192.168.101.131:/home/hadoop/.ssh/

sbin/start-dfs.sh
sbin/start-yarn.sh

8 管理地址

hadoop： http://master:50070

yarn： http://master:8088

9 基本命令

hadoop fs -mkdir /test
hadoop fs -put /usr/local/hadoop-2.2.0/bin/hdfs /test
