1 大数据实战系列-spark+hadoop集成环境搭建

1 准备环境

192.168.0.251 shulaibao1
192.168.0.252 shulaibao2
hadoop-2.8.0-bin
spark-2.1.1-bin-hadoop2.7
关闭selinux：
/etc/selinux/config：SELINUX=disabled

增加hadoop用户组与用户

$groupadd -g 1000 hadoop$ useradd -u 2000 -g hadoop hadoop
$mkdir -p /home/data/app/hadoop$ chown -R hadoop:hadoop /home/data/app/hadoop
$passwd hadoop

配置无密码登录

$ssh-keygen -t rsa$ cd /home/hadoop/.ssh $cp id_rsa.pub authorized_keys_hadoop1$ scp authorized_keys_hadoop2
hadoop@hadoop1:/home/hadoop/.ssh $scp authorized_keys_hadoop3 hadoop@hadoop1:/home/hadoop/.ssh 使用$ cat authorized_keys_hadoop1 >>
authorized_keys 命令使用$scp authorized_keys
hadoop@hadoop2:/home/hadoop/.ssh把密码文件分发出去

1.1 安装jdk

推荐jdk1.8

1.2 安装并设置protobuf

注：该程序包需要在gcc安装完毕后才能安装，否则提示无法找到gcc编译器。

1.2.1 下载protobuf安装包

推荐版本2.5+
下载链接为： https://code.google.com/p/protobuf/downloads/list
这里写图片描述

1.2.2使用ssh工具把protobuf-2.5.0.tar.gz包上传到/home/data/software目录

这里写图片描述

1.2.3 解压安装包

这里写图片描述

$tar -zxvf protobuf-2.5.0.tar.gz

1.2.4 把protobuf-2.5.0目录转移到/usr/local目录下

$sudo mv protobuf-2.5.0 /usr/local
这里写图片描述

进入目录以root用户运行如下命令：

#./configure
#make
#make check
#make install

这里写图片描述

1.2.6 验证是否安装成功

运行成功之后，通过如下方式来验证是否安装成功
这里写图片描述

#protoc

这里写图片描述

2 安装hadoop

tar -zxvf 
mkdir tmp
Mdkdir name 
Mkdir data

2.2 hadoop核心配置

配置路径：/home/data/app/hadoop/etc/hadoop

2.2 hadoop-env.sh yarn-env.sh环境配置

/home/hadoop/.bash_profile增加环境变量

export JAVA_HOME=/home/data/software/jdk1.8.0_121
export HADOOP_HOME=/home/data/app/hadoop/hadoop-2.8.0
export PATH=$PATH:/home/data/app/hadoop/hadoop-2.8.0/bin

Hadoop-env.sh修改export

HADOOP_CONF_DIR= ${HADOOP_CONF_DIR:-"$ HADOOP_HOME/etc/hadoop”}
2.3 分发到Scp -r source target -h -p2.4 验证hdfs

路径：/home/data/app/hadoop/hadoop-2.8.0/bin

初始化格式化namenode

$./bin/hdfs namenode -format

启动hdfs

$./start-dfs.sh
