创建服务器,参考

虚拟机创建服务器

|----------|---------------|------------|---|---|
| 节点名字 | 节点IP | 系统版本 | | |
| master11 | 192.168.50.11 | centos 8.5 | | |
| slave12 | 192.168.50.12 | centos 8.5 | | |
| slave13 | 192.168.50.13 | centos 8.5 | |

1 下载组件

Hadoop:官网地址

Hbase:官网地址

ZooKeeper:官网下载

Hive:官网下载

Sqoop:官网下载

为方便同学们下载，特整理到网盘

2 通过xftp 上传软件到服务器,统一放到/data/soft/

3 配置ZooKeeper

tar zxvf apache-zookeeper-3.8.4-bin.tar.gz
mv apache-zookeeper-3.8.4-bin/ /data/zookeeper
#修改配置文件
cd /data/zookeeper/conf
cp zoo_sample.cfg zoo.cfg
#创建数据保存目录
mkdir  -p /data/zookeeper/zkdata
mkdir -p /data/zookeeper/logs
vim zoo.cfg
dataDir=/tmp/zookeeper-->dataDir=/data/zookeeper/zkdata
dataLogDir=/data/zookeeper/logs
server.1=master11:2888:3888
server.2=slave12:2888:3888
server.3=slave13:2888:3888

#配置环境变量
vim /etc/profile
export ZooKeeper_HOME=/data/zookeeper
export PATH=$PATH:$ZooKeeper_HOME/bin
source  /etc/profile

#新建myid并且写入对应的myid

[root@master11 zkdata]# cat myid 
1
#对应修改
slave12
myid--2
slave13
myid--3

4 配置HBase

tar  zxvf  hbase-2.5.8-bin.tar.gz
mv  hbase-2.5.8/ /data/hbase
mkdir -p /data/hbase/logs
#vim /etc/profile
export HBASE_LOG_DIR=/data/hbase/logs
export HBASE_MANAGES_ZK=false
export HBASE_HOME=/data/hbase
export PATH=$PATH:$ZooKeeper_HOME/bin
#vim  /data/hbase/conf/regionservers
slave12
slave13
#新建backup-masters
vim  /data/hbase/conf/backup-masters
slave12
#vim  /data/hbase/conf/hbase-site.xml
 <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
  </property>
<!--HBase端口--> 
<property>
 <name>hbase.master.info.port</name>
 <value>16010</value>
</property>
<property>
    <name>hbase.zookeeper.quorum</name>
    <value>master11,slave12,slave13</value>
  </property>
<property>
    <name>hbase.rootdir</name>
    <value>hdfs://master11:9000/hbase</value>
  </property>
<property>
  <name>hbase.wal.provider</name>
  <value>filesystem</value>
</property>

5 配置hadoop

tar zxvf hadoop-3.4.0.tar.gz
mv  hadoop-3.4.0/ /data/hadoop
#配置环境变量
vim /etc/profile
export HADOOP_HOME=/data/hadoop
export PATH=$PATH:$HADOOP_HOME/bin:$PATH:$HADOOP_HOME/sbin
source /etc/profile
#查看版本
[root@master11 soft]# hadoop version
