Anaconda2-4.2.0-Linux-x86_64.sh 【 http://continuum.io/downloads#all】

jdk-8u111-linux-x64.tar.gz 【 http://continuum.io/downloads#all】

spark-1.5.2-bin-hadoop2.6.tgz 【 http://spark.apache.org/downloads】

1. Installing Java 8

cd Downloads
ls
mkdir -p /usr/lib/jvm
sudo mv jdk-8u111-linux-x64.tar.gz /usr/lib/jvm
cd /usr/lib/jvm
sudo tar xzvf jdk-8u11-linux-i586.tar.gz
sudo ln -s jdk1.8.0_111 java-8

设置环境变量
vi ~/.bashrc
在文件末尾追加：
export JAVA_HOME=/usr/lib/jvm/java-8
export JAVA_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
:wq保存退出

source ~/.bashrc 使上述修改生效

java-version

【注意：:$PATH不写、写错或者写成小写，则原始路径直接被覆盖，导致系统找不到原始路径，ls等基础命令失效】
【如果不小心覆盖了原始路径，命令行输入export PATH=/usr/bin:/bin 然后输入 vi ~/.bashrc 找错改正】

更新默认jdk

# update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8.0_05/bin/java 300
# update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.8.0_05/bin/javac 300
# update-alternatives --config java

2. Installing Anaconda with Python 2.7

命令：bash Anaconda2-4.2.0-Linux-x86_64.sh

3. Installing Spark

cd Downloads

mkdir -p /home/用户名/spark

tar -xf spark-1.5.2-bin-hadoop2.6.tgz
sudo mv spark-1.5.2-bin-hadoop2.6 /home/用户名/spark

cd /home/用户名/spark/spark-1.5.2-bin-hadoop2.6

./bin/pyspark

4. Enabling Jupyter Notebook

命令：jupyter notebook

connect Jupyter to Spark:

命令：PYSPARK_DRIVER_PYTHON=jupyter PYSPARK_DRIVER_PYTHON_OPTS="notebook" $SPARK_HOME/bin/pyspark --master local[*]
