su spark
cd ~
pwd
mkdir softwares修改语系为英文语系(全节点)
# 显示目前所支持的语系

su spark
cd ~ssh-keygen -t rsa -P ''- 将每个节点生成的id_rsa.pub里面的内容拷贝出来
- 将所有节点拷贝好的公钥一起拷贝到每个节点用户家目录下的
.ssh的authorized_keys这个文件中 - 每个节点的
authorized_keys这个文件访问权限必须改成600，chmod 600 authoried_keys
上传软件(master节点)
把环境安装准备的软件jdk、Hadoop、Spark、Scala上传到sparkmaster:/home/spark/softwares
安装jdk(master节点)
tar -zxvf jdk-8u91-linux-x64.tar.gz
vi ~/.bashrc
export JAVA_HOME=/home/spark/softwares/jdk1.8.0_91
export PATH=$PATH:$JAVA_HOME/bin
source ~/.bashrc
which java安装Scala(master节点)
tar -zxvf scala-2.11.8.tgz
vi ~/.bashrc
export SCALA_HOME=/home/spark/softwares/scala-2.11.8
export PATH=$PATH:$JAVA_HOME/bin:$SCALA_HOME/bin
source ~/.bashrc
which scala安装Hadoop(master节点)
tar -zxvf hadoop-2.7.3.tar.gzHadoop配置文件所在目录：/home/spark/softwares/hadoop-2.7.3/etc/hadoop

vi ~/.bashrc
export HADOOP_HOME=/home/spark/softwares/hadoop-2.7.3
export PATH=$PATH:$JAVA_HOME/bin:$SCALA_HOME/bin:$HADOOP_HOME/bin
source ~/.bashrc安装Spark(master节点)

source ~/.bashrc搭建本地yum源(local方式)(master节点)
挂载iso镜像文件，拷贝文件内容
su root
mkdir -p /mnt/CentOS /mnt/dvd
mount /dev/cdrom /mnt/dvd
df -h
cp -av /mnt/dvd/* /mnt/CentOS
umount /mnt/dvd备份原有yum配置文件，
cd /etc/yum.repos.d
rename .repo .repo.bak *.repo新建yum配置文件
vi /etc/yum.repos.d/local.repo
[local]
name=CentOS-$releasever - Local
baseurl=file:///mnt/CentOS
enabled=1
gpgcheck=0
# 验证
yum list | grep mysql搭建本地yum源(http方式)(master节点)
启动httpd服务
# 验证是否安装httpd服务
rpm -qa|grep httpd
# yum install -y httpd
yum install -y httpd
# 启动httpd服务
# service httpd start
systemctl status httpd.service
systemctl start httpd.service
# 设置httpd服务开机自启动
# chkconfig httpd on
systemctl is-enabled httpd.service
systemctl enable httpd.service安装yum源
# 在/var/www/html/下创建文件夹CentOS7
mkdir -p /var/www/html/CentOS7
# 将iso文件中的内容copy到CentOS7
# cp -av /mnt/CentOS/* /var/www/html/CentOS7/
# rm -rf /mnt/CentOS/*
mv /mnt/CentOS/* /var/www/html/CentOS7/利用ISO镜像，yum源搭建OK。浏览器验证访问：
使用yum源
# 备份原有的repo文件
# mkdir -p /etc/yum.repos.d/repo.bak
# cd /etc/yum.repos.d/
# cp *.repo *.repo.bak repo.bak/
# rm -rf *.repo *.repo.bak
cd /etc/yum.repos.d/
# 新建文件CentOS-http.repo
vi CentOS-http.repo
[http]
name=CentOS-$releasever - http
baseurl=http://sparkmaster:80/CentOS7/
enabled=1
gpgcheck=1
gpgkey=http://sparkmaster:80/CentOS7/RPM-GPG-KEY-CentOS-7
# 把前面搭建的本地yum源禁用，设置local.repo中的enabled=0
# 更新yum源
yum clean
yum repolist集群yum源配置(http方式)(全节点)
# sparknode1/sparknode2
cd /etc/yum.repos.d
rename .repo .repo.bak *.repo
# sparkmaster
scp /etc/yum.repos.d/*.repo sparknode1:/etc/yum.repos.d/
scp /etc/yum.repos.d/*.repo sparknode2:/etc/yum.repos.d/异步传输工具(全节点)
利用异步传输工具进行master节点下/home/spark/softwares所安装软件jdk、Hadoop、Spark、Scala的同步。
rpm -qa | grep rsync
yum list | grep rsync
yum install -y rsync
vi sync_tools.sh
echo "-----begin to sync jobs to other workplat-----"
SERVER_LIST='sparknode1 sparknode2'
for SERVER in $SERVER_LIST
do
rsync -avz ./* $SERVER:/home/spark/softwares
done
echo "-----sync jobs is done-----"cd ~/softwares
chmod 700 sync_tools.sh
./sync_tools.sh环境变量配置同步(全节点)
# sparknode1/sparknode2
mv ~/.bashrc ~/.bashrc.bak
# sparkmaster
su spark
scp ~/.bashrc sparknode1:~/.bashrc
scp ~/.bashrc sparknode2:~/.bashrc
# sparknode1/sparknode2
source ~/.bashrc启动Spark及验证
cd $SPRAK_HOME
cd sbin
./stop-all.sh
./start-all.sh
jps验证：
启动HDFS及验证
cd $HADOOP_HOME
# 格式化
hadoop namenode -format
cd ../sbin
./stop-all.sh
./start-dfs.sh
jps验证:
至此，Spark2.0环境搭建结束。
