source /etc/profile

 修改spark配置

cd /usr/local/spark-2.1.1-bin-hadoop2.7/

vi ./conf/spark-env.sh.template

export JAVA_HOME=/usr/java/jdk1.8.0_144/

export SCALA_HOME=/usr/local/scala-2.12.3/

保存退出

mv spark-env.sh.template spark-env.sh

 

#修改slaves

[[email protected] conf]# vi slaves.template

192.168.2.32

192.168.2.33

[[email protected] conf]# mv slaves.template slaves

 

2.1 三台主机上修改hosts

vi /etc/hosts

192.168.2.31 master

192.168.2.32 slave001

192.168.2.33 slave002

4. 启动服务

[[email protected] local]# cd hadoop-2.7.3/sbin/

修改配置文件vi /usr/local/hadoop-2.7.3/etc/hadoop/hadoop-env.sh

export JAVA_HOME=/usr/java/jdk1.8.0_144/

./start-all.sh

localhost: Warning: Permanently added ‘localhost‘ (RSA) to the list of known hosts.

localhost: Error: JAVA_HOME is not set and could not be found.

修改配置文件

vi /usr/local/hadoop-2.7.3/etc/hadoop/hadoop-env.sh

export JAVA_HOME=/usr/java/jdk1.8.0_144/

重新启动服务

sbin/start-all.sh

#启动spark

cd /usr/local/spark-2.1.1-bin-hadoop2.7/sbin/

./start-all.sh

4. 安装tensorflow

前提下先安装cuda
vim /etc/yum.repos.d/linuxtech.testing.repo  
添加内容：
[cpp] view plain copy
[linuxtech-testing]  
name=LinuxTECH Testing  
baseurl=http://pkgrepo.linuxtech.net/el6/testing/  
enabled=0  
gpgcheck=1  
gpgkey=http://pkgrepo.linuxtech.net/el6/release/RPM-GPG-KEY-LinuxTECH.NET  
 
sudo rpm -i cuda-repo-rhel6-8.0.61-1.x86_64.rpm
sudo yum clean all
sudo yum install cuda
rpm -ivh --nodeps dkms-2.1.1.2-1.el6.rf.noarch.rpm 
yum install cuda
yum install epel-release
yum install -y zlib* 
#软连接cuda
ln -s /usr/local/cuda-8.0 /usr/local/cudaldconfig /usr/local/cuda/lib64
Vi /etc/profile
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cuda/extras/CUPTI/lib64"
export CUDA_HOME=/usr/local/cuda

 

更新pip
pip install --upgrade pip
下载tensorflow
pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.8.0-cp27-none-linux_x86_64.whl
安装好后
#python

放入最新的glibc库，解压出6.0.20

libstdc++.so.6.0.20 覆盖原来的libstdc++.so.6

[[email protected] 4.4.7]# ln -s /opt/libstdc++.so.6/libstdc++.so.6.0.20 /usr/lib64/libstdc++.so.6

ln: creating symbolic link `/usr/lib64/libstdc++.so.6‘: File exists

这个地方特别要注意坑特别多，一定要覆盖原来的。

pip install tensorflowonspark

 

这样就可以使用了

报错信息：

报错：ImportError: /lib64/libc.so.6: version `GLIBC_2.17‘ not found (required by /usr/local/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so)

tar zxvf glibc-2.17.tar.gz  

mkdir build  

cd build  

../glibc-2.17/configure  --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin  

make -j4  

make install  

测试验证tensorflow

import tensorflow as tf
import numpy as np
x_data = np.float32(np.random.rand(2, 100)) 
y_data = np.dot([0.100, 0.200], x_data) + 0.300
 
b = tf.Variable(tf.zeros([1]))
W = tf.Variable(tf.random_uniform([1, 2], -1.0, 1.0))
y = tf.matmul(W, x_data) + b
 
loss = tf.reduce_mean(tf.square(y - y_data))
optimizer = tf.train.GradientDescentOptimizer(0.5)
train = optimizer.minimize(loss)
 
init = tf.initialize_all_variables()
 
sess = tf.Session()
sess.run(init)
 
 
for step in xrange(0, 201):
    sess.run(train)
    if step % 20 == 0:
        print step, sess.run(W), sess.run(b)
 
# 得到最佳拟合结果 W: [[0.100  0.200]], b: [0.300]

确保etc/profile
export JAVA_HOME=/usr/java/jdk1.8.0_144/
export SCALA_HOME=/usr/local/scala-2.12.3/
export PATH=$PATH:/usr/local/scala-2.12.3/bin
export SPARK_HOME=/usr/local/spark-2.1.1-bin-hadoop2.7/
export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cuda/extras/CUPTI/lib64"
export CUDA_HOME=/usr/local/cuda
export PYTHONPATH=$SPARK_HOME/python:$SPARK_HOME/python/lib/py4j-0.10.4-src.zip:$PYTHONPATH

完成实验。
