hbase 2.3.x 安装之三 hadoop

旧城等待， 2022-09-07 12:20 133阅读 0赞

os: centos 7.6.1810  
db: hbase 2.3.x  
hadoop 2.10.x  
zookeeper 3.6  
jdk 1.8

hbase 是运行在 hadoop 之上，hadoop 又是运行在 jvm 之上。  
索引 hbase、hadoop、jdk 的版本选择就得考虑兼容性

节点规划，实验用

192.168.56.221  hb1
    192.168.56.222  hb2
    192.168.56.223  hb3

# 版本 #

# cat /etc/centos-release
    CentOS Linux release 7.6.1810 (Core)

# hadoop 2.10.x #

所有节点创建用户，保持 id 一致

# groupadd -g 600 hadoop;
    useradd -u 600 -g hadoop -G hadoop hadoop;
    
    # passwd hadoop

所有节点 hadoop 用户下配置到其余节点 ssh 信任

# su - hadoop
    $ ssh-keygen -t rsa
    $ cd /home/hadoop/.ssh/
    $ ls -l
    total 8
    -rw------- 1 hadoop hadoop 1675 Aug 19 15:21 id_rsa
    -rw-r--r-- 1 hadoop hadoop  392 Aug 19 15:21 id_rsa.pub
    
    $ touch authorized_keys;
    chmod 600 authorized_keys;
    
    $ ssh-copy-id hadoop@hb1;
    $ ssh-copy-id hadoop@hb2;
    $ ssh-copy-id hadoop@hb3;
    
    $ chmod 700 ../.ssh/

# vi /etc/ssh/sshd_config
    RSAAuthentication yes
    PubkeyAuthentication yes
    AuthorizedKeysFile      .ssh/authorized_keys
    
    
    # service sshd restart

所有节点下载安装 hadoop(也可以从一台机器下载，然后拷贝到其余节点)

# cd /usr/local/
    # wget https://downloads.apache.org/hadoop/common/hadoop-2.10.1/hadoop-2.10.1.tar.gz
    # tar -zxvf ./hadoop-2.10.1.tar.gz
    # chown -R hadoop:hadoop ./hadoop-2.10.1
    # ln -s ./hadoop-2.10.1 hadoop-2.10

所有节点 /etc/profile 最后面追加环境变量

# vi /etc/profile
    
    export HADOOP_HOME=/usr/local/hadoop-2.10
    export PATH=.:${HADOOP_HOME}/bin:${HADOOP_HOME}/sbin:${PATH}

所有节点重新登录，或者 source 下环境变量文件

# source /etc/profile

所有节点创建一些必要的目录

# su - hadoop
    $ 
    $ mkdir -p /home/hadoop/{data,tmp,name,journal}

# hadoop 2.10.x 参数配置 #

仅在 hb1 节点下编辑如下文件。

1.  hadoop-env.sh 、yarn-env.sh 配置JAVA\_HOME

$ vi ./etc/hadoop/hadoop-env.sh
    
    export JAVA_HOME=/usr/lib/jvm/java-1.8.0

$ vi ./etc/hadoop/yarn-env.sh
    
    export JAVA_HOME=/usr/lib/jvm/java-1.8.0

2．core-site.xml

cp /usr/local/hadoop-2.10/etc/hadoop/core-site.xml   /home/hadoop/tmp_peiyb/core-site.xml;
    cp /usr/local/hadoop-2.10/etc/hadoop/hdfs-site.xml   /home/hadoop/tmp_peiyb/hdfs-site.xml;
    cp /usr/local/hadoop-2.10/etc/hadoop/mapred-site.xml /home/hadoop/tmp_peiyb/mapred-site.xml;
    cp /usr/local/hadoop-2.10/etc/hadoop/slaves          /home/hadoop/tmp_peiyb/slaves;
    cp /usr/local/hadoop-2.10/etc/hadoop/yarn-site.xml   /home/hadoop/tmp_peiyb/yarn-site.xml;
    cp /usr/local/hadoop-2.10/etc/hadoop/hadoop-env.sh   /home/hadoop/tmp_peiyb/hadoop-env.sh;
    cp /usr/local/hadoop-2.10/etc/hadoop/yarn-env.sh     /home/hadoop/tmp_peiyb/yarn-env.sh;

hb1 节点上**参数文件同步**到 hb2、hb3 节点上

scp /usr/local/hadoop-2.10/etc/hadoop/core-site.xml   hadoop@hb2:/usr/local/hadoop-2.10/etc/hadoop/core-site.xml;
    scp /usr/local/hadoop-2.10/etc/hadoop/hdfs-site.xml   hadoop@hb2:/usr/local/hadoop-2.10/etc/hadoop/hdfs-site.xml;
    scp /usr/local/hadoop-2.10/etc/hadoop/mapred-site.xml hadoop@hb2:/usr/local/hadoop-2.10/etc/hadoop/mapred-site.xml;
    scp /usr/local/hadoop-2.10/etc/hadoop/slaves          hadoop@hb2:/usr/local/hadoop-2.10/etc/hadoop/slaves;
    scp /usr/local/hadoop-2.10/etc/hadoop/yarn-site.xml   hadoop@hb2:/usr/local/hadoop-2.10/etc/hadoop/yarn-site.xml;

    scp /usr/local/hadoop-2.10/etc/hadoop/core-site.xml   hadoop@hb3:/usr/local/hadoop-2.10/etc/hadoop/core-site.xml;
    scp /usr/local/hadoop-2.10/etc/hadoop/hdfs-site.xml   hadoop@hb3:/usr/local/hadoop-2.10/etc/hadoop/hdfs-site.xml;
    scp /usr/local/hadoop-2.10/etc/hadoop/mapred-site.xml hadoop@hb3:/usr/local/hadoop-2.10/etc/hadoop/mapred-site.xml;
    scp /usr/local/hadoop-2.10/etc/hadoop/slaves          hadoop@hb3:/usr/local/hadoop-2.10/etc/hadoop/slaves;
    scp /usr/local/hadoop-2.10/etc/hadoop/yarn-site.xml   hadoop@hb3:/usr/local/hadoop-2.10/etc/hadoop/yarn-site.xml;
    scp /usr/local/hadoop-2.10/etc/hadoop/hadoop-env.sh   hadoop@hb3:/usr/local/hadoop-2.10/etc/hadoop/hadoop-env.sh;
    scp /usr/local/hadoop-2.10/etc/hadoop/yarn-env.sh     hadoop@hb3:/usr/local/hadoop-2.10/etc/hadoop/yarn-env.sh;

# 格式化 #

hb1、hb2、hb3 节点依次启动JN。

$ hadoop-daemon.sh start journalnode

hb1 主节点执行,对HDFS进行格式化

$ hdfs namenode -format

hb1节点执行，启动NN

$ hadoop-daemon.sh start namenode

hb2节点执行，启动申请 standby 文件

$ hdfs namenode -bootstrapStandby

hb1 主节点执行,主节点切换控制信息进行格式化(仅执行一次)

$ hdfs zkfc -formatZK

# 启动 hadoop #

hb1 主节点执行

$ start-dfs.sh
    
    $ jps

hb1 主节点执行

$ start-yarn.sh
    
    $ jps
    
    849 JournalNode
    2626 ResourceManager
    2805 NodeManager
    2470 DFSZKFailoverController
    1063 NameNode
    2108 DataNode
    3213 Jps
