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

yum install -y gcc
wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
tar vxf Python-2.7.13.tgz
cd Python-2.7.13.tgz
./configure --prefix=/usr/local
make && make install

[root@master opt]# python
Python 2.7.13 (default, Aug 24 2017, 16:10:35)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-18)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

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

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.xml
<configuration>
    <property>
        <name>hadoop.tmp.dir</name>
        <value>file:/usr/local/hadoop/tmp</value>
        <description>Abase for other temporary directories.</description>
    </property>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://master:9001</value>
    </property>
</configuration>

配置slave

[root@slave001 hadoop-2.7.3]# vi ./etc/hadoop/core-site.xml
<configuration>
    <property>
        <name>hadoop.tmp.dir</name>
        <value>file:/usr/local/hadoop/tmp</value>
        <description>Abase for other temporary directories.</description>
    </property>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://slave001:9001</value>
    </property>
</configuration>

[root@slave002 hadoop-2.7.3]# vi ./etc/hadoop/core-site.xml

    <property>
        <name>hadoop.tmp.dir</name>
        <value>file:/usr/local/hadoop/tmp</value>
        <description>Abase for other temporary directories.</description>
    </property>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://slave002:9001</value>
    </property>
</configuration>

1.8.3 配置hdfs

vi /usr/local/hadoop-2.7.3/etc/hadoop/hdfs-site.xml
<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
    <property>

    </property>
    <property>
        <name>dfs.namenode.rpc-address</name>
        <value>master:9001</value>
    </property>
</configuration>

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/

export SPARK_DRIVER_MEMORY=1g

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=//pkgrepo.linuxtech.net/el6/testing/
enabled=0
gpgcheck=1
gpgkey=//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

ImportError: libcudart.so.7.5: cannot open shared object file: No such file or directory

#这是因为lib库不完整
yum install openssl -y
