• HDFS 伪分布式集群搭建


    伪分布式集群搭建

    1、伪分布式搭建

    1.1、先配置JDK环境

    上传后解压JDK到/usr/java/

    export JAVA_HOME=/usr/java/jdk1.8.0_221
    export JRE_HOME=/usr/java/jdk1.8.0_221/jre
    export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
    export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
    

    1.2、免密登录

    [root@MDNode01 ~]# ssh-keygen -t rsa
    Generating public/private rsa key pair.
    Enter file in which to save the key (/root/.ssh/id_rsa): 
    Created directory '/root/.ssh'.
    Enter passphrase (empty for no passphrase): 
    Enter same passphrase again: 
    Your identification has been saved in /root/.ssh/id_rsa.
    Your public key has been saved in /root/.ssh/id_rsa.pub.
    The key fingerprint is:
    c3:5f:8d:47:39:1d:bf:8b:ac:cb:60:64:25:8b:9f:66 root@MDNode01
    The key's randomart image is:
    +--[ RSA 2048]----+
    |               . |
    |               oo|
    |         . .  + o|
    |       .. +  + ..|

    |           +.    |

    1.3、解压Hadoop

    [root@MDNode01 software]# ll
    total 402372
    -rw-r--r-- 1 root root 216929574 Nov 14 02:55 hadoop-2.7.5.tar.gz

    drwxr-xr-x 9 20415 101 4096 Dec 16  2017 hadoop-2.7.5

    [root@MDNode01 hadoop-2.7.5]# ll

    [root@MDNode01 hadoop-2.7.5]# 
    

    1.4、配置HADOOP_HOME变量

    export JAVA_HOME=/usr/java/jdk1.8.0_221
    export JRE_HOME=/usr/java/jdk1.8.0_221/jre
    export HADOOP_HOME=/opt/mgs/hadoop-2.7.5

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

    1.5、配置Hadoop的JDK环境变量

    /opt/service/jdk1.8.0_221

    [root@MDNode01 hadoop]# pwd
    /opt/mgs/hadoop-2.7.5/etc/hadoop

    修改vi hadoop-env.sh
    # The only required environment variable is JAVA_HOME.  All others are

    # The java implementation to use.
    export JAVA_HOME=/usr/java/jdk1.8.0_221
    
    修改 vi mapred-env.sh

    export HADOOP_JOB_HISTORYSERVER_HEAPSIZE=1000
    
    export HADOOP_MAPRED_ROOT_LOGGER=INFO,RFA
    
    修改 vi yarn-env.sh

    if [ "$JAVA_HOME" != "" ]; then
      #echo "run java in $JAVA_HOME"
      JAVA_HOME=$JAVA_HOME
    
    

    1.6、配置全局

    core-site.xml
    <configuration>
        <property>
            <name>fs.defaultFS</name>
            <value>hdfs://MDNode01:9000</value>
        </property>
        <!--配置输出的文件目录,不采用默认的文件路径-->
        <property>
            <name>hadoop.tmp.dir</name>
            <value>/var/mgs/hadoop/pseudo</value>
        </property>
    </configuration>
    

    主节点的配置

    hdfs-site.xml
    <configuration>
        <property>
            <name>dfs.replication</name>
            <!--伪分布式只要配置一个副本就可以了-->
            <value>1</value>
        </property>
        <!--配置namenode.secondary的节点和端口号-->
         <property>
            <name>dfs.namenode.secondary.http-address</name>
            <value>MDNode01:50090</value>
        </property>
    </configuration>
    
    
    slaves
    MDNode01
    

    配置DataNode

    1.7、格式化【生成镜像文件】

    [root@MDNode01 hadoop]# hdfs namenode -format
    19/11/14 04:54:05 INFO namenode.NameNode: STARTUP_MSG:

    在自定义的文件夹路径的/dfs/name/current/下面存放着NameNode的相关配置文件输出的信息

    layoutVersion=-63
    

    1.8、启动伪分布式集群

    [root@MDNode01 hadoop-2.7.5]# start-dfs.sh 
    Starting namenodes on [MDNode01]
    MDNode01: starting namenode, logging to /opt/mgs/hadoop-2.7.5/logs/hadoop-root-namenode-MDNode01.out

    Starting secondary namenodes [MDNode01]

    [root@MDNode01 hadoop-2.7.5]# jps

    1720 DataNode
    1977 Jps
    1868 SecondaryNameNode
    [root@MDNode01 hadoop-2.7.5]# 
    

    1.9、查看相关生存的文件

    产生相对于的三个角色的配置文件目录

    [root@MDNode01 dfs]# pwd
    /var/mgs/hadoop/pseudo/dfs
    [root@MDNode01 dfs]# ll
    total 12
    drwx------ 3 root root 4096 Nov 14 05:10 data

    [root@MDNode01 dfs]# cd data/

    [root@MDNode01 data]# cd current/
    [root@MDNode01 current]# ll

    -rw-r--r-- 1 root root  229 Nov 14 05:10 VERSION
    [root@MDNode01 current]# cat VERSION 
    #Thu Nov 14 05:10:28 CST 2019
    storageID=DS-bc5408ea-44b6-45c2-9866-4b95bcafe10e
    clusterID=CID-56b9d3a0-f7ce-4a59-b8ef-96c4222e82ce
    cTime=0
    datanodeUuid=9e6cd277-f5a5-403e-91b3-21f0a5804625
    storageType=DATA_NODE
    layoutVersion=-56
    

    可以看到的集群ID是和主节点相同的

    [root@MDNode01 current]# cd BP-1669788457-192.168.25.50-1573678447143/
    [root@MDNode01 BP-1669788457-192.168.25.50-1573678447143]# ll
    total 12
    drwxr-xr-x 4 root root 4096 Nov 14 05:10 current
    -rw-r--r-- 1 root root  166 Nov 14 05:10 scanner.cursor
    drwxr-xr-x 2 root root 4096 Nov 14 05:10 tmp
    [root@MDNode01 BP-1669788457-192.168.25.50-1573678447143]# cd current/
    [root@MDNode01 current]# ll
    total 12
    drwxr-xr-x 2 root root 4096 Nov 14 05:10 finalized
    drwxr-xr-x 2 root root 4096 Nov 14 05:10 rbw

    [root@MDNode01 current]# cd finalized/
    [root@MDNode01 finalized]# ll
    total 0
    

    可以看到当前的节点上的Block数据为0,是因为没有数据

    可视化

    使用浏览器访问:



    1.10、创建文件目录

    [root@MDNode01 ~]# hdfs dfs -mkdir -p /user/root
    [root@MDNode01 ~]# hdfs dfs -ls /

    测试上传文件是一个Hadoop的压缩包

    [root@MDNode01 software]# hdfs dfs -put hadoop-2.7.5.tar.gz /user/root
    [root@MDNode01 software]# hdfs dfs -ls /user/root/
    Found 1 items	
    -rw-r--r--   1 root supergroup  216929574 2019-11-14 05:45 /user/root/hadoop-2.7.5.tar.gz
    
    [root@MDNode01 subdir0]# pwd
    /var/mgs/hadoop/pseudo/dfs/data/current/BP-1669788457-192.168.25.50-1573678447143/current/finalized/subdir0/subdir0
    [root@MDNode01 subdir0]# ll -lh

    [root@MDNode01 subdir0]# 
    

    可视化展示:

    文件的默认Block块的大小是128MB


    删除文件

    [root@MDNode01 logs]# hdfs dfs -rm /user/root/hadoop-2.7.5.tar.gz
    19/11/14 06:04:11 INFO fs.TrashPolicyDefault: Namenode trash configuration: Deletion interval = 0 minutes, Emptier interval = 0 minutes.
    Deleted /user/root/hadoop-2.7.5.tar.gz
    

    1.12、关闭集群

    [root@MDNode01 logs]# stop-dfs.sh 
    Stopping namenodes on [MDNode01]
    MDNode01: stopping namenode
    MDNode01: stopping datanode
    Stopping secondary namenodes [MDNode01]
    MDNode01: stopping secondarynamenode
    [root@MDNode01 logs]# jps
    2657 Jps
    [root@MDNode01 logs]#
