2、安装JDK 和 Hadoop 并配置JDK和Hadoop的环境变量

3、配置完全分布式集群

4、集群配置

1）集群部署规划

2）配置文件说明

3）配置集群

5、集群启动与测试

1）workers的配置

2）启动集群

Hadoop运行模式——完全分布式

1、准备3台虚拟机（关闭防火墙、配置静态IP 和主机名称）

2、安装JDK 和 Hadoop 并配置JDK和Hadoop的环境变量

3、配置完全分布式集群

4、集群配置

1）集群部署规划

（1）注意事项

A、NameNode 和 SecondaryNameNode 不要安装在同一台服务器，比较耗内存

B、ResourceManager很消耗内存，不要和NameNode、SecondaryNameNode 配置在同一台服务器

2）配置文件说明

Hadoop配置文件分为2类：

默认配置文件和自定义配置文件，当用户想修改某个默认配置值时，才需要修改自定义配置文件，更改相应属性值

（1）默认配置文件

默认配置文件	文件存放在Hadoop的jar包中的位置
【core-default.xml】	hadoop-common-3.1.3.jar/core-default.xml
【hdfs-default.xml】	hadoop-hdfs-3.1.3.jar/hdfs-default.xml
【yarn-default.xml】	hadoop-yarn-common-3.1.3.jar/yarn-default.xml
【mapred-default.xml】	hadoop-mapreduce-client-core-3.1.3.jar/mapred-default.xml

（2）自定义配置文件

core-site.xml、hdfs-site.xml、yarn-site.xml、mapred-site.xml 四个配置文件存放在 $HADOOP_HOME/etc/hadoop 这个路径上，用户可以根据项目需求重新进行修改配置

本次生产环境上的路径：

cd   /opt/module/hadoop-3.1.3/etc/hadoopls | grep -iE "core-site.xml|hdfs-site.xml|mapred-site.xml|yarn-site.xml"

3）配置集群

（1）核心配置文件

hadoop102 配置 core-site.xml 文件

cd   $HADOOP_HOME/etc/hadoopvim  core-site.xml

core-site.xml配置文件内容如下：

<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <!-- 指定NameNode的地址 -->    <property>        <name>fs.defaultFS</name>        <!-- 指定Hadoop内部通讯地址 -->        <value>hdfs://hadoop102:8020</value>    </property>
    <!-- 指定hadoop数据的存储目录 -->    <property>        <name>hadoop.tmp.dir</name>        <value>/opt/module/hadoop-3.1.3/data</value>    </property>
    <!-- 配置HDFS网页登录使用的静态用户为zola -->    <property>        <name>hadoop.http.staticuser.user</name>        <value>zola</value>    </property></configuration>

fs.defaultFS 属性：

根据 1）集群部署规划的（1）注意事项 里面的规划表来填写配置表，指定 NameNode的地址，默认值为：file:/// 是个文件协议的本地地址，如下图1所示为默认数值。修改为：hdfs://hadoop102:8020，用hdfs协议，部署在 hadoop102上，使用服务端口 8020 或者使用9000或9820都可以，推荐使用 8020

图1

hadoop.tmp.dir 属性：

hadoop中HDFS要存储数据，这些数据存储的目录地址，默认值为：/tmp/hadoop-${user.name}，如下图2所示为默认值，在本环境 Linux系统里面是指：/tmp/hadoop-zola，但是 /tmp 目录是1个临时目录，一般Linux系统1个月清理一次。修改为：/opt/module/hadoop-3.1.3/data，这里data目录若不存在会自动创建

图2

hadoop.http.staticuser.user 属性：

配置 HDFS 网页登录使用的静态用户为 zola ，这个配置参数可以先不配置，后期需要的时候再进行配置，默认值如下图3所示

配置文件添加内容：

（2）HDFS 配置文件

hadoop102 配置 hdfs-site.xml 文件

cd   $HADOOP_HOME/etc/hadoopvim  hdfs-site.xml

hdfs-site.xml配置文件内容如下：

<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration><!-- nn web端访问地址，给外部访问提供的接口--><property>        <name>dfs.namenode.http-address</name>        <value>hadoop102:9870</value>    </property><!-- 2nn web端访问地址-->    <property>        <name>dfs.namenode.secondary.http-address</name>        <value>hadoop104:9868</value>    </property></configuration>

dfs.namenode.http-address 属性：

NameNode（nn）要让 HDFS从 web页面访问，也需要暴露一个端口来提供访问，这里配置为：hadoop102:9870，

dfs.namenode.secondary.http-address 属性：

SecondaryNameNode（2nn）要让 HDFS 从 web页面访问，也需要暴露一个端口来提供访问，根据 1）集群部署规划的（1）注意事项 里面的规划表来填写配置表，这里配置为：hadoop104:9868，

配置文件添加内容：

（3）YARN 配置文件

hadoop102 配置 hdfs-site.xml 文件

cd   $HADOOP_HOME/etc/hadoopvim  yarn-site.xml

yarn-site.xml配置文件内容如下：

<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="configuration.xsl"?><configuration>
    <!-- 指定MR走shuffle -->    <property>        <name>yarn.nodemanager.aux-services</name>        <value>mapreduce_shuffle</value>    </property>    <!-- 指定ResourceManager的地址-->    <property>        <name>yarn.resourcemanager.hostname</name>        <value>hadoop103</value>    </property>    <!-- 环境变量的继承 -->    <property>        <name>yarn.nodemanager.env-whitelist</name>        <value>JAVA_HOME,HADOOP_COMMON_HOME,HADOOP_HDFS_HOME,HADOOP_CONF_DIR,CLASSPATH_PREPEND_DISTCACHE,HADOOP_YARN_HOME,HADOOP_MAPRED_HOME</value>    </property>    </configuration>

yarn.nodemanager.aux-services 属性：

MR走什么协议，默认推荐是走 mapreduce_shuffle ，以 shuffle 的方式进行后续的资源调度

resourcemanager 属性：

resourcemanager 部署地址，根据 1）集群部署规划的（1）注意事项 里面的规划表来填写配置表，指定 ResourceManager 的地址为 hadoop103

yarn.nodemanager.env-whitelist 属性：

这里Hadoop 3.1.3版本里面环境变量的继承中有1个小 bug ，到了Hadoop 3.2.X版本以上就不需要进行配置环境变量了，而且 HADOOP_MAPRED_HOME 也自动添加上了，对比原配置文件里面的数值和本次修改的数值差异

#原配置文件里面yarn.nodemanager.env-whitelist的数值JAVA_HOME,HADOOP_COMMON_HOME,HADOOP_HDFS_HOME,HADOOP_CONF_DIR,CLASSPATH_PREPEND_DISTCACHE,HADOOP_YARN_HOME,HADOOP_HOME,PATH,LANG,TZ#本次修改的yarn.nodemanager.env-whitelist数值JAVA_HOME,HADOOP_COMMON_HOME,HADOOP_HDFS_HOME,HADOOP_CONF_DIR,CLASSPATH_PREPEND_DISTCACHE,HADOOP_YARN_HOME,HADOOP_MAPRED_HOME

（4）MapReduce 配置文件

hadoop102 配置 mapred-site.xml 文件

cd   $HADOOP_HOME/etc/hadoopvim  mapred-site.xml

mapred-site.xml 配置文件内容如下：

<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet type="text/xsl" href="configuration.xsl"?><configuration>    <!-- 指定MapReduce程序运行在Yarn上 -->    <property>        <name>mapreduce.framework.name</name>        <value>yarn</value>    </property></configuration>

mapreduce.framework.name 属性：

MapReduce默认是 local 本地运行，本次设置运行是在 yarn 上运行。修改配置文件时，可以先进入默认配置文件 mapred-default.xml 里面查询一下默认的配置

配置文件添加内容：

（1）（2）（3）（4）操作至此，已经在 Hadoop102 上完成了集群的配置，还需要在 Hadoop103、Hadoop104 上进行相同的配置，才算是将集群完整配置完成

（5）在集群的 Hadoop102 上分发配置好的Hadoop配置文件，到其它节点

#执行分发脚本xsync /opt/module/hadoop-3.1.3/etc/hadoop/#执行结果如下：==================== hadoop102 ====================sending incremental file list

（6）验证配置文件分发结果，在 Hadoop103、Hadoop104 上进行验证

cat /opt/module/hadoop-3.1.3/etc/hadoop/core-site.xmlcat /opt/module/hadoop-3.1.3/etc/hadoop/mapred-site.xml

验证结果如下：成功分发

5、集群启动与测试

1）workers的配置

集群完成配置后，在启动集群之前，还需要配置workers节点，集群中有几个节点， /opt/module/hadoop-3.1.3/etc/hadoop/workers配置文件里面对应的就配置几个主机名称

（1）在Hadoop102 上的 workers 增加如下内容：

#修改前查看原有配置 为 localhost ，删掉即可cat     /opt/module/hadoop-3.1.3/etc/hadoop/workerslocalhost#正式进行修改操作vim    /opt/module/hadoop-3.1.3/etc/hadoop/workershadoop102hadoop103hadoop104#查看修改结果，进行核实验证cat     /opt/module/hadoop-3.1.3/etc/hadoop/workershadoop102hadoop103hadoop104

注意：/opt/module/hadoop-3.1.3/etc/hadoop/workers文件中添加的内容，结尾不允许有空格，文件中也不允许有空行。因为启动脚本会读取调用该文件里面的主机名称，程序读取时没有去空格化，文件里面有空格会一起读取到，导致启动时找不到对应的主机名，从而导致集群启动失败

（2）在Hadoop102 上把workers 配置文件同步到所有集群节点

#执行同步脚本xsync  /opt/module/hadoop-3.1.3/etc#同步脚本执行结果==================== hadoop102 ====================sending incremental file list

sent 944 bytes  received 19 bytes  1,926.00 bytes/sectotal size is 119,854  speedup is 124.46==================== hadoop103 ====================sending incremental file listetc/hadoop/etc/hadoop/workers

sent 1,024 bytes  received 51 bytes  2,150.00 bytes/sectotal size is 119,854  speedup is 111.49==================== hadoop104 ====================sending incremental file listetc/etc/hadoop/etc/hadoop/workers

sent 1,027 bytes  received 54 bytes  2,162.00 bytes/sectotal size is 119,854  speedup is 110.87

（3）验证Hadoop102上分发的配置文件，在集群其它节点上 Hadoop103、Hadoop104 核实workers 配置文件

cat /opt/module/hadoop-3.1.3/etc/hadoop/workers

验证结果，正常分发

2）启动集群

（1）第一次启动集群需要先进行初始化（将namenode记账本清空）

第一次启动集群时，需要先进行初始化，就好比买了1个U盘第一次使用时，需要先进行格式化U盘一样。注意只是在第一次启动集群时需要进行初始化，之后启动集群就不需要进行初始化了，因为初始化操作相当于清理掉集群原有的数据，就好比并不是每次使用U盘都需要进行格式化一样，格式化U盘会导致数据丢失

A、需要在 hadoop102 节点格式化NameNode（注意：格式化NameNode，会产生新的集群id，导致NameNode和DataNode的集群id不一致，集群找不到以往数据。如果集群在运行过程中报错，需要重新格式化NameNode的话，一定要先停止namenode和datanode进程，并且要删除所有机器的data和logs目录，然后再进行格式化）

B、在 Hadoop103 、 Hadoop104上检查对比，没有在 Hadoop家目录下生成 data 和 logs目录，因为目前初始化的只是 Hadoop102

C、查看对应的 Version文件

[zola@hadoop102 hadoop-3.1.3]$ cat /opt/module/hadoop-3.1.3/data/dfs/name/current/VERSION#返回结果如下#Tue Sep 19 17:01:46 CST 2023namespaceID=940819608clusterID=CID-7bb9461a-be2b-4f90-8864-d524fc637f96cTime=1695114106480storageType=NAME_NODEblockpoolID=BP-1910090487-10.0.2.102-1695114106480layoutVersion=-64

（2）启动HDFS

A、步骤（1）初始化完成后，正式启动集群，启动集群的HDFS，启动指令在 Hadoop家目录的 sbin 目录下

B、集群启动完毕后，验证是否与最初规划相符合在本文的（4、集群配置 1）集群部署规划 （1）注意事项 ）规划如下图

C、Web端查看HDFS的NameNode

登录HDFS组件提供的页面

在本地PC机上配置hosts解析文件

（3）在配置了ResourceManager的节点（hadoop103）,启动YARN

A、查看最初的规划如下图所示：
