[hadoop@master ~]$ ssh-copy-id 172.20.2.250

[hadoop@master ~]$ ssh-copy-id 172.20.2.110

三. 安装 Hadoop

3.1 解压安装包

1、下载 [ Master节点执行 ]

[hadoop@master ~]$ wget http://mirrors.hust.edu.cn/apache/hadoop/common/hadoop-2.9.1/hadoop-2.9.1.tar.gz

1	[hadoop@master ~]$ wget http://mirrors.hust.edu.cn/apache/hadoop/common/hadoop-2.9.1/hadoop-2.9.1.tar.gz

2、使用hadoop用户，创建安装目录：/home/hadoop/apps，创建数据目录：/home/hadoop/data：[ Master节点执行 ]

[hadoop@master ~]$ pwd
/home/hadoop
[hadoop@master ~]$ mkdir apps
[hadoop@master ~]$ mkdir data
[hadoop@master ~]$ ls
apps  data  hadoop-2.9.1.tar.gz

[hadoop@master ~]$ pwd

/home/hadoop

[hadoop@master ~]$ mkdir apps

[hadoop@master ~]$ mkdir data

[hadoop@master ~]$ ls

apps data hadoop-2.9.1.tar.gz

3、在apps文件夹下解压安装包：[ Master节点执行 ]

[hadoop@master ~]$ tar -zxf hadoop-2.9.1.tar.gz  -C apps/
[hadoop@master ~]$ ll apps/
total 0
drwxr-xr-x. 9 hadoop hadoop 149 Apr 16  2018 hadoop-2.9.1

[hadoop@master ~]$ tar -zxf hadoop-2.9.1.tar.gz -C apps/

[hadoop@master ~]$ ll apps/

total 0

drwxr-xr-x. 9 hadoop hadoop 149 Apr 16 2018 hadoop-2.9.1

3.2 Master节点配置

1、Master 节点配置

进入配置文件目录：/home/hadoop/apps/hadoop-2.9.1/etc/hadoop

2、配置core-site.xml

fs.defaultFS ：这个属性用来指定namenode的hdfs协议的文件系统通信地址，可以指定一个主机+端口，也可以指定为一个namenode服务（这个服务内部可以有多台namenode实现ha的namenode服务。

hadoop.tmp.dir : hadoop集群在工作的时候存储的一些临时文件的目录。

[hadoop@master hadoop]$ vim core-site.xml

1	[hadoop@master hadoop]$ vim core-site.xml

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://master:9000</value>
    </property>
 
    <property>
        <name>hadoop.tmp.dir</name>
        <value>/home/hadoop/data/hadoopdata</value>
    </property>
</configuration>

<name>fs.defaultFS</name>

<value>hdfs://master:9000</value>

</property>

<name>hadoop.tmp.dir</name>

<value>/home/hadoop/data/hadoopdata</value>

</property>

</configuration>

3、配置hdfs-site.xml

dfs.namenode.name.dir：namenode数据的存放地点。也就是namenode元数据存放的地方，记录了hdfs系统中文件的元数据。

dfs.datanode.data.dir： datanode数据的存放地点。也就是block块存放的目录了。

dfs.replication：hdfs的副本数设置。也就是上传一个文件，其分割为block块后，每个block的冗余副本个数，默认配置是3。

dfs.secondary.http.address：secondarynamenode 运行节点的信息，和 namenode 不同节点

[hadoop@master hadoop]$ vim hdfs-site.xml

1	[hadoop@master hadoop]$ vim hdfs-site.xml

<configuration>
    <property>
        <name>dfs.namenode.name.dir</name>
        <value>/home/hadoop/data/hadoopdata/name</value>
        <description>为了保证元数据的安全一般配置多个不同目录</description>
    </property>
 
    <property>
        <name>dfs.datanode.data.dir</name>
        <value>/home/hadoop/data/hadoopdata/data</value>
        <description>datanode 的数据存储目录</description>
    </property>
 
    <property>  
        <name>dfs.replication</name>
        <value>2</value>
        <description>HDFS 的数据块的副本存储个数, 默认是3</description>
    </property>
 
    <property>
        <name>dfs.secondary.http.address</name>
        <value>slave2:50090</value>
        <description>secondarynamenode 运行节点的信息，和 namenode 不同节点</description>
    </property>
</configuration>

<name>dfs.namenode.name.dir</name>

<value>/home/hadoop/data/hadoopdata/name</value>

<description>为了保证元数据的安全一般配置多个不同目录</description>

</property>

<name>dfs.datanode.data.dir</name>

<value>/home/hadoop/data/hadoopdata/data</value>

<description>datanode 的数据存储目录</description>

</property>

<name>dfs.replication</name>

<description>HDFS 的数据块的副本存储个数, 默认是3</description>

</property>

<name>dfs.secondary.http.address</name>

<value>slave2:50090</value>

<description>secondarynamenode 运行节点的信息，和 namenode 不同节点</description>

</property>

</configuration>

4、配置mapred-site.xml

mapreduce.framework.name：指定mr框架为yarn方式，Hadoop二代MP也基于资源管理系统Yarn来运行。

[hadoop@master hadoop]$ cp mapred-site.xml.template mapred-site.xml
 
[hadoop@master hadoop]$ vim mapred-site.xml

[hadoop@master hadoop]$ cp mapred-site.xml.template mapred-site.xml

[hadoop@master hadoop]$ vim mapred-site.xml

5、配置yarn-site.xml

yarn.resourcemanager.hostname：yarn总管理器的IPC通讯地址

yarn.nodemanager.aux-services：YARN 集群为 MapReduce 程序提供的服务（常指定为 shuffle ）

[hadoop@master hadoop]$ vim yarn-site.xml

1	[hadoop@master hadoop]$ vim yarn-site.xml

<configuration>
 
<!-- Site specific YARN configuration properties -->
    <property>
        <name>yarn.resourcemanager.hostname</name>
        <value>slave3</value>
    </property>
 
    <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
        <description>YARN 集群为 MapReduce 程序提供的 shuffle 服务</description>
    </property>
</configuration>

<name>yarn.resourcemanager.hostname</name>

<value>slave3</value>

</property>

<name>yarn.nodemanager.aux-services</name>

<value>mapreduce_shuffle</value>

<description>YARN 集群为 MapReduce 程序提供的 shuffle 服务</description>

</property>

</configuration>

6、配置 Slaves

[hadoop@master hadoop]$ vim slaves

1	[hadoop@master hadoop]$ vim slaves

3.3 slave节点配置 [ 所有slave节点执行 ]

每台服务器中的hadoop安装包的目录必须一致，安装包的配置信息还必须保持一致

在slave1节点上，同样使用hadoop用户：

[hadoop@slave1 ~]$ mkdir apps

1	[hadoop@slave1 ~]$ mkdir apps

在master节点上：

[hadoop@master hadoop]$ scp -r ~/apps/hadoop-2.9.1/ hadoop@slave1:~/apps/hadoop-2.9.1/
[hadoop@master hadoop]$ scp -r ~/apps/hadoop-2.9.1/ hadoop@slave2:~/apps/hadoop-2.9.1/
[hadoop@master hadoop]$ scp -r ~/apps/hadoop-2.9.1/ hadoop@slave3:~/apps/hadoop-2.9.1/

[hadoop@master hadoop]$ scp -r ~/apps/hadoop-2.9.1/ hadoop@slave1:~/apps/hadoop-2.9.1/

[hadoop@master hadoop]$ scp -r ~/apps/hadoop-2.9.1/ hadoop@slave2:~/apps/hadoop-2.9.1/

[hadoop@master hadoop]$ scp -r ~/apps/hadoop-2.9.1/ hadoop@slave3:~/apps/hadoop-2.9.1/

3.4 Hadoop环境变量配置 [ 所有节点执行 ]

千万注意：

1、如果你使用root用户进行安装。 vi /etc/profile 即可系统变量

2、如果你使用普通用户进行安装。 vi ~/.bashrc 用户变量（我是使用hadoop用户安装的）

[hadoop@master ~]$ pwd
/home/hadoop
[hadoop@master ~]$ vim .bashrc

[hadoop@master ~]$ pwd

/home/hadoop

[hadoop@master ~]$ vim .bashrc

# User specific aliases and functions
 
export HADOOP_HOME=/home/hadoop/apps/hadoop-2.9.1
 
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:

# User specific aliases and functions

export HADOOP_HOME=/home/hadoop/apps/hadoop-2.9.1

export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:

四初始化 Hadoop [ Master节点执行 ]

HDFS初始化只能在HDFS集群的主节点namenode上进行，本实验中即为master节点

[hadoop@master ~]$ hadoop namenode -format
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.

五启动 Hadoop

5.1 启动HDFS（HDFS集群的任何节点都可以）

[hadoop@master ~]$ start-dfs.sh
Starting namenodes on [master]
The authenticity of host 'master (172.20.2.68)' can't be established.
ECDSA key fingerprint is 81:c3:e3:15:8e:6e:65:d8:e8:0c:c0:c8:0b:e7:e5:07.
Are you sure you want to continue connecting (yes/no)? yes
master: Warning: Permanently added 'master' (ECDSA) to the list of known hosts.
master: starting namenode, logging to /home/hadoop/apps/hadoop-2.9.1/logs/hadoop-hadoop-namenode-master.out
master: starting datanode, logging to /home/hadoop/apps/hadoop-2.9.1/logs/hadoop-hadoop-datanode-master.out

5.2 启动YARN（在YARN主节点ResourceManager上执行）

只能在YARN的主节点resourcemanager中进行启动，也就是本集群的slave3。

[hadoop@slave3 ~]$ start-yarn.sh
starting yarn daemons
starting resourcemanager, logging to /home/hadoop/apps/hadoop-2.9.1/logs/yarn-hadoop-resourcemanager-slave3.out
slave2: starting nodemanager, logging to /home/hadoop/apps/hadoop-2.9.1/logs/yarn-hadoop-nodemanager-slave2.out
master: starting nodemanager, logging to /home/hadoop/apps/hadoop-2.9.1/logs/yarn-hadoop-nodemanager-master.out
