CentOS7 install spark+ipython-nodebook

ipython-nodebook

1. IPython notebook 目前已经成为用 Python 做教学、计算、科研的一个重要工具。

2. IPython Notebook 使用浏览器作为界面，向后台的 IPython 服务器发送请求，并显示结果。

3. 在浏览器的界面中使用单元(Cell)保存各种信息。Cell 有多种类型，经常使用的有表示格式化文本的 Markdown单元，和表示代码的 Code单元。

yum install net-tools.x86_64

2. install vim

yum search vim
yum install vim-enhanced

3. install wget

[libin@centos-linux-1 x]$ yum search wget

wget.x86_64 : A utility for retrieving files using the HTTP or FTP protocols

 Name and summary matches only, use "search all" for everything.

[libin@centos-linux-1 x]$ yum install wget.x86_64

4. install Jdk

# green install jdk-7u80-linux-x64.gz
# edit /etc/profile add
## libin add ##

### JAVA ###
JAVA_HOME=/home/x/jdk
JAVA_BIN=$JAVA_HOME/bin
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/jre/lib/dt.jar:$JAVA_HOME/jre/lib/tools.jar
export JAVA_HOME JAVA_BIN PATH CLASSPATH
"/etc/profile" 86L, 2035C

# /etc/profile：该文件是用户登录时，操作系统定制用户环境时使用的第一个文件，应用于登录到系统的每一个用户。 对所有用户有效 ##

5. install Scala

# green install scala-2.10.4.tgz
# edit /etc/profile add

### Scala ###
#export SCALA_HOME=/usr/local/xSoft/scala
export SCALA_HOME=/home/x/scala
export PATH=${SCALA_HOME}/bin:$PATH

6. install Spark (Standalone)

green install spark-1.5.2-bin-hadoop2.6.tgz
cp conf/spark-env.sh.template conf/spark-env.sh

edit conf/spark-env.sh add

export JAVA_HOME=/home/x/jdk
export SCALA_HOME=/home/x/scala
export SPARK_HOME=/home/x/spark
export SPARK_MASTER_IP=192.168.181.113
export MASTER=spark://192.168.181.113:7077

export SPARK_EXECUTOR_INSTANCES=2
export SPARK_EXECUTOR_CORES=1

export SPARK_WORKER_MEMORY=1000m

export SPARK_LIBRARY_PATH=${SPARK_HOME}/lib

#export SPARK_LAUNCH_WITH_SCALA=0
#export SCALA_LIBRARY_PATH=${SPARK_HOME}/lib


#export SPARK_LIBRARY_PATH=/home/deploy/spark/spark-1.5.2-bin-hadoop2.6/lib

7. install ipython-nodebook

openssh、zlib

yum -y install openssh-clients
yum install zlib

setuptools、pip

tar xvf setuptools-18.1.tar.gz
cd setuptools-18.1
sudo python setup.py build
sudo python setup.py install

tar xvf pip-8.1.0.tar.gz
cd pip-8.1.0
sudo python setup.py build
sudo python setup.py install

ipython、matplotlib

sudo pip install ipython
sudo pip install matplotlib

python-dev、g++

sudo yum install python-devel （如果没有安装 python 源代码，会报找不到 Python.h 的头文件错误）
sudo yum install gcc-c++

install python-notebook

# 前面install的各种py相关, 为个这一步

sudo pip install notebook

8. start-up notebook

PYSPARK_DRIVER_PYTHON=ipython PYSPARK_DRIVER_PYTHON_OPTS="notebook --ip=192.168.181.113" /home/x/spark/bin/pyspark

浏览器访问 http://192.168.181.113:8888/notebooks

9. spark-notebook example1

%pylab inline
%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt

data =[33,25,20,12,10]
plt.figure(num=1, figsize=(6,6))
plt.axes(aspect=1)
plt.title('Plot 3', size=14)
plt.pie(data, labels=('Group 1','Group 2','Group 3','Group 4','Group 5'))
plt.savefig('/home/x/spark/test_libin/plot3.png', format='png')

maybe attention point

python -V

#若系统默认是python2.6，需要升级到2.7
tar xvf Python-2.7.tgz
./configure --with-zlib=/usr/include --prefix=/usr/local/python27 --prefix=/usr/local/python27

make
make install
mv /usr/bin/python /usr/bin/python_old
ln -s /usr/local/python27/bin/python /usr/bin/
python
此处已经可以正常使用python2.7了
但是因为yum是使用的2.6的版本来用的，所以 还需要修改一下
[root@wangyuelou Python-2.7.2]# vim /usr/bin/yum
#!/usr/bin/python   #修改此处为2.6的位置
