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−g1000hadoopuseradd -u 2000 -g hadoop hadoop
mkdir−p/home/data/app/hadoopchown -R hadoop:hadoop /home/data/app/hadoop
$passwd hadoop

配置无密码登录

ssh−keygen−trsacd /home/hadoop/.ssh cpidrsa.pubauthorizedkeyshadoop1scp authorized_keys_hadoop2
hadoop@hadoop1:/home/hadoop/.ssh scpauthorizedkeyshadoop3hadoop@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

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

1.2.3 解压安装包

$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

进入目录以root用户运行如下命令：

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

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

#protoc

2.1 上传、解压、创建目录

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
