Hadoop / Zookeeper / Hbase
因资源有限 这三个都是安装在同一台Centos7.9的机器上
但通过配置 所以在逻辑上是distributed模式 1 Java安装
1.1 下载java11
tar/opt/java/jdk-11.0.5/
1.2 环境配置修改
文件/etc/profile
export JAVA_HOME/opt/java/jdk-11.0.5/ export CLASSPATH$JAVA_HOME/lib export PATH$PATH:$JAVA_HOME/bin
执行命令使之生效
$ source /etc/profile 2 Hadoop安装
2.1 创建hadoop用户
$ adduser hadoop 2.2 修改用户目录配置
/home/hadoop/.bashrc
export HADOOP_HOME/home/bigdata/hadoop/ export PATH$HADOOP_HOME/sbin:$HADOOP_HOME/bin:$PATH 1.3 下载Hadoop
Apache Hadoop
下载的版本是3.3.6
tar到目录/home/bigdata/hadoop/ 1.4 修改hadoop相关配置
/home/bigdata/hadoop/etc/hadoop/core-site.xml
property namehadoop.tmp.dir/name valuefile:/home/bigdata/hadoopTmp/value descriptionAbase for other temporary directories./description /property property namefs.defaultFS/name valuehdfs://localhost:9000/value /property /home/bigdata/hadoop/etc/hadoop/hadoop-env.sh
export JAVA_HOME/opt/java/jdk-11.0.5/ /home/bigdata/hadoop/etc/hadoop/hdfs-site.xml
property namedfs.replication/name value1/value /property property namedfs.namenode.name.dir/name valuefile:/home/bigdata/hadoopTmp/dfs/name/value /property
property namedfs.namenode.checkpoint.dir/name valuefile:/home/bigdata/hadoopTmp/dfs/namesecondary/value /property property namedfs.datanode.data.dir/name valuefile:/home/bigdata/hadoopTmp/dfs/data/value /property 1.5 初始化hdfs
cd /home/bigdata/hadoop
$ hdfs namenode -format 1.6 启动hdfs
cd /home/bigdata/hadoop/sbin/
$ ./start-dfs.sh 3 ZooKeeper安装
3.1 下载ZooKeeper
Apache ZooKeeper
版本是3.8.3
tar到目录/home/bigdata/zookeeper/ 3.2 配置修改
3.2.1 配置改名
mv /home/bigdata/zookeeper/conf/zoo_sample.cfg /home/bigdata/zookeeper/conf/zoo.cfg
3.2.2 打开配置
vi /home/bigdata/zookeeper/conf/zoo.cfg
3.2.3 修改配置
dataDir/home/bigdata/zookeeper/dataDir dataLogDir/home/bigdata/zookeeper/dataLogDir
3.2.4 启动zookeeper
cd /home/bigdata/zookeeper/bin/
./zkServer.sh start
通过jps查看zk的进程 3.2.5 查看状态
cd /home/bigdata/zookeeper/bin/
./zkServer.sh status Hbase安装
1 修改bashrc配置
export HBASE_HOME/home/bigdata/hbase/ export PATH$PATH:$HBASE_HOME/bin
生效
$ source /home/hadoop/.bashrc 2 修改hbase配置文件
/home/bigdata/hbase/conf/hbase-env.sh
export JAVA_HOME/opt/java/jdk-11.0.5/ export HBASE_CLASSPATH/home/bigdata/hbase/conf/ export HBASE_MANAGES_ZKfalse /home/bigdata/hbase/conf/hbase-site.xml Start
/home/bigdata/hbase/bin/start-hbase.sh
http://localhost:16010 Shell
/home/bigdata/hbase/bin/hbase shell Shell - Command
create / list / describe / put / scan / get / display / drop / quit
create test, cf list test describe test put test, row1, cf:a, value1 put test, row2, cf:b, value2 put test, row3, cf:c, value3 scan test get test, row1 disable test enable test drop test Stop
/home/bigdata/hbase/bin/hbase-daemon.sh stop master
/home/bigdata/hbase/bin/stop.hbase.sh 看到最后 觉得还是看apache的吧
