3 .安装
1.1 删除系统自带jdk:
# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.99-2.6.5.1.el6.x86_64 rpm -e --nodeps java-1.6.0-openjdk-1.6.0.38-1.13.10.4.el6.x86_64 rpm -e --nodeps tzdata-java-2016c-1.el6.noarch
1.2 安装jdk
rpm -ivh jdk-8u144-linux-x64.rpm
1.3添加java路径
export JAVA_HOME=/usr/java/jdk1.8.0_144
1.4 验证java
[root@master opt]# java -version java version "1.8.0_144" Java(TM) SE Runtime Environment (build 1.8.0_144-b01) Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)
1.5 Ssh免登陆设置
cd /root/.ssh/ ssh-keygen -t rsa cat id_rsa.pub >> authorized_keys scp id_rsa.pub authorized_keys root@192.168.2.32:/root/.ssh/ scp id_rsa.pub authorized_keys root@192.168.2.31:/root/.ssh/
1.6安装python2.7和pip

1.7 安装pip和setuptools
tar zxvf pip-1.5.4.tar.gz tar zxvf setuptools-2.0.tar.gz cd setuptools-2.0 python setup.py install cd pip-1.5.4 python setup.py install
1.8 Hadoop安装和配置
1.8.1 三台机器都要安装Hadoop
tar zxvf hadoop-2.7.3.tar.gz -C /usr/local/ cd /usr/local/hadoop-2.7.3/bin [root@master bin]# ./hadoop version Hadoop 2.7.3 Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git -r baa91f7c6bc9cb92be5982de4719c1c8af91ccff Compiled by root on 2016-08-18T01:41Z Compiled with protoc 2.5.0 From source with checksum 2e4ce5f957ea4db193bce3734ff29ff4 This command was run using /usr/local/hadoop-2.7.3/share/hadoop/common/hadoop-common-2.7.3.jar
1.8.2 配置hadoop
配置master vi /usr/local/hadoop-2.7.3/etc/hadoop/core-site.xmlhadoop.tmp.dir file:/usr/local/hadoop/tmp Abase for other temporary directories. fs.defaultFS hdfs://master:9001
配置slave
[root@slave001 hadoop-2.7.3]# vi ./etc/hadoop/core-site.xmlhadoop.tmp.dir file:/usr/local/hadoop/tmp Abase for other temporary directories. fs.defaultFS hdfs://slave001:9001
[root@slave002 hadoop-2.7.3]# vi ./etc/hadoop/core-site.xmlhadoop.tmp.dir file:/usr/local/hadoop/tmp Abase for other temporary directories. fs.defaultFS hdfs://slave002:9001
1.8.3 配置hdfs
vi /usr/local/hadoop-2.7.3/etc/hadoop/hdfs-site.xmldfs.replication 1 dfs.namenode.name.dir file:/usr/local/hadoop/tmp/dfs/name dfs.datanode.data.dir file:/usr/local/hadoop/tmp/dfs/data dfs.namenode.rpc-address master:9001
1.9 安装scala
tar -zxvf scala-2.12.3.tgz -C /usr/local/ #修改变量添加scala vi /etc/profile export SCALA_HOME=/usr/local/scala-2.12.3/ export PATH=$PATH:/usr/local/scala-2.12.3/bin source /etc/profile
2.0三台机器都要安装spark
tar -zxvf spark-2.1.1-bin-hadoop2.7.tgz -C /usr/local/ vi /etc/profile export JAVA_HOME=/usr/java/jdk1.8.0_144/ export SCALA_HOME=/usr/local/scala-2.12.3/ export PATH=$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 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/
#export SPARK_HOME=/usr/local/spark-2.1.1-bin-hadoop2.7/
export SPARK_MASTER_IP=192.168.2.31
export SPARK_WORKER_MEMORY=1g
export HADOOP_CONF_DIR=/usr/local/hadoop-2.7.3/etc/hadoop
export HADOOP_HDFS_HOME=/usr/local/hadoop-2.7.3/

保存退出
mv spark-env.sh.template spark-env.sh
#修改slaves
[root@master conf]# vi slaves.template
192.168.2.32
192.168.2.33
[root@master 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
[root@master 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 >>> import tensorflow Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python2.7/site-packages/tensorflow/__init__.py", line 23, in from tensorflow.python import * File "/usr/local/lib/python2.7/site-packages/tensorflow/python/__init__.py", line 45, in from tensorflow.python import pywrap_tensorflow File "/usr/local/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow.py", line 28, in _pywrap_tensorflow = swig_import_helper() File "/usr/local/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow.py", line 24, in swig_import_helper _mod = imp.load_module('_pywrap_tensorflow', fp, pathname, description) ImportError: libcudart.so.7.5: cannot open shared object file: No such file or directory

pip install tensorflowonspark
这样就可以使用了

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。
