阿里云部署Hbase集群

安装环境

主机 ip 操作系统
master 10.30.45.239 centos7.4
slave1 10.31.155.33 centos7.4
slave2 10.81.233.67 centos7.4

阿里云3台ecs搭建一个小型的hbase分布式数据存储(这里的ip都是内网)。一台作为主master两台作为从slave。

安装步骤

  • 安装vim编辑器
  • 安装ssh
  • 配置ssh免密码登陆
  • 安装jdk
  • 安装hadoop
  • 安装zookeeper
  • 安装时间同步服务 NTP
  • 安装hbase

准备工作

版本

centos7.4 内核为3.10
Hadoop 2.8.3
Hbase 1.2.6
Zookeeper 3.4.10
Sqoop 1.4.7
Phoenix 4.13.1

修改hostname

# vim /etc/hostname 
输入自定义主机名 ,三台都要改

修改hosts文件

分别登陆三台主机,修改hosts

vim /etc/hosts
--添加以下信息(三台都要改)
10.30.45.239 master
10.31.155.33 slave1
10.81.233.67 slave2

写这篇文章的时候是2018年4月。适当选择稳定的版本安装。下载官网如下:

设置3台ecs之间免密登陆

方便后期之间文件复制。

# # slave1
# ssh-keygen -t rsa
-- 不用输入密码,一路回车就行
# cp ~/.ssh/id_rsa.pub ~/.ssh/slave1_id_rsa.pub
# scp ~/.ssh/slave1_id_rsa.pub master:~/.ssh/

# # slave2
# ssh-keygen -t rsa
# cp ~/.ssh/id_rsa.pub ~/.ssh/slave2_id_rsa.pub
# scp ~/.ssh/slave2_id_rsa.pub master:~/.ssh/

# # master
ssh-keygen -t rsa
# cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
# cat ~/.ssh/slave1_id_rsa.pub >> ~/.ssh/authorized_keys
# cat ~/.ssh/slave2_id_rsa.pub >> ~/.ssh/authorized_kyes
-- 拷贝文件至slave1及slave2
# scp ~/.ssh/authorized_keys slave1:~/.ssh
# scp ~/.ssh/authorized_keys slave2:~/.ssh

关闭防火墙及SELINUX(master、slave1、slave2均需修改)

-- 关闭防火墙
# systemctl stop firewalld.service
# systemctl disable firewalld.service

-- 关闭SELINUX
# vim /etc/selinux/config
-- 注释掉
#SELINUX=enforcing
#SELINUXTYPE=targeted
-- 添加
SELINUX=disabled

设置时间同步

这里省略,第一我懒得配,第二阿里云有自动同步

安装jdk

登陆master
-- 解压jdk安装包
# mkdir /usr/java
# tar -zxvf jdk-8u131-linux-x64.tar.gz -C /usr/java

-- 拷贝jdk至slave1及slave2中
# scp -r /usr/java slave1:/usr
# scp -r /usr/java slave2:/usr

-- 设置jdk环境变量(master、slave1、slave2均需修改)
# vim /etc/environment
JAVA_HOME=/usr/java/jdk1.8.0_131
JRE_HOME=/usr/java/jdk1.8.0_131/jre

# vim /etc/profile
export JAVA_HOME=/usr/java/jdk1.8.0_131
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

搭建Hadoop环境

解压安装

登陆master
# tar -zxvf hadoop-2.8.3-x64.tar.gz -C /usr
# cd /usr/hadoop-2.8.3
# mkdir tmp logs hdf hdf/data hdf/name

修改Hadoop配置文件

-- 修改 slaves 文件
# vim /usr/hadoop-2.8.3/etc/hadoop/slaves
-- 删除 localhost,添加
slave1
slave2

-- 修改 core-site.xml 文件
# vim /usr/hadoop-2.8.3/etc/hadoop/core-site.xml
-- 在 configuration 节点中添加以下内容
<property>
    <name>fs.default.name</name>
    <value>hdfs://master:9000</value>
</property>
<property>
    <name>hadoop.tmp.dir</name>
    <value>file:/usr/hadoop-2.8.3/tmp</value>
</property>

-- 修改 hdfs-site.xml 文件
# vim /usr/hadoop-2.8.3/etc/hadoop/hdfs-site.xml
-- 在 configuration 节点添加以下内容
<property>
    <name>dfs.datanode.data.dir</name>
    <value>/usr/hadoop-2.8.3/hdf/data</value>
    <final>true</final>
</property>
<property>
    <name>dfs.namenode.name.dir</name>
    <value>/usr/hadoop-2.8.3/hdf/name</value>
    <final>true</final>
</property>

-- 修改 mapred-site.xml 文件
# cp /usr/hadoop-2.8.3/etc/hadoop/mapred-site.xml.template /usr/hadoop-2.8.3/etc/hadoop/mapred-site.xml
# vim /usr/hadoop-2.8.3/etc/hadoop/mapred-site.xml
-- 在 configuration 节点添加以下内容
<property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
</property>
<property>
    <name>mapreduce.jobhistory.address</name>
    <value>master:10020</value>
</property>
<property>
    <name>mapreduce.jobhistory.webapp.address</name>
    <value>master:19888</value>
</property>

-- 修改 yarn-site.xml 文件
# vim /usr/hadoop-2.8.3/etc/hadoop/yarn-site.xml
-- 在 configuration 节点添加以下内容
<property>
    <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
    <value>org.apache.mapred.ShuffleHandler</value>

</property>
<property>
    <name>yarn.resourcemanager.webapp.address</name>
    <value>master:8088</value>
</property>

复制hadoop到slave节点

# scp -r /usr/hadoop-2.8.3 slave1:/usr
# scp -r /usr/hadoop-2.8.3 slave2:/usr

配置 master 和 slave 的 hadoop 环境变量

# vim /etc/profile
-- 添加如下内容
export HADOOP_HOME=/usr/hadoop-2.8.3
export PATH=$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH
export HADOOP_LOG_DIR=/usr/hadoop-2.8.3/logs
export YARN_LOG_DIR=$HADOOP_LOG_DIR

-- 保存后执行
# source /etc/profile

# vim ~/.bashrc
-- 添加如下内容
export HADOOP_PREFIX=/usr/hadoop-2.8.3/

-- 保存后执行
# source ~/.bashrc

格式化 namenode

# /usr/hadoop-2.8.3/sbin/hdfs namenode -format

启动 hadoop(仅在master节点执行)

# ssh master
# /usr/hadoop-2.8.3/sbin/start-all.sh

到这一步已经成功完成了hadoop环境的搭建

Zookeeper环境搭建

解压缩 zookeeper 安装包到master,并建立基本目录

# tar -zxvf zookeeper-3.4.10.tar.gz -C /usr
# mkdir /usr/zookeeper-3.4.10/data

修改master配置文件

-- 复制配置文件模板
# cp /usr/zookeeper-3.4.10/conf/zoo-sample.cfg /usr/zookeeper-3.4.10/conf/zoo.cfg

-- 修改配置文件
# vim /usr/zookeeper-3.4.10/conf/zoo.cfg
-- 添加如下内容
dataDir=/usr/zookeeper-3.4.10/data
server.1=master:2888:3888
server.2=slave1:2888:3888
server.3=slave2:2888:3888

复制到各个子节点

# scp -r /usr/zookeeper-3.4.10 slave1:/usr
# scp -r /usr/zookeeper-3.4.10 slave2:/usr

创建myid文件

-- master节点添加myid文件
# ssh master
# touch /usr/zookeeper-3.4.10/data/myid
# echo 1 > /usr/zookeeper-3.4.10/data/myid

-- slave1节点添加myid文件
# ssh slave1
# touch /usr/zookeeper-3.4.10/data/myid
# echo 2 > /usr/zookeeper-3.4.10/data/myid

-- slave2节点添加myid文件
# ssh slave2
# touch /usr/zookeeper-3.4.10/data/myid
# echo 3 > /usr/zookeeper-3.4.10/data/myid

启动zookeeper(master、slave1、slave2均需执行)

-- 启动master
# ssh master
# cd /usr/zookeeper-3.4.10/bin
# ./zkServer.sh start

-- 启动slave1
# ssh slave1
# cd /usr/zookeeper-3.4.10/bin
# ./zkServer.sh start

-- 启动slave2
# ssh slave2
# cd /usr/zookeeper-3.4.10/bin
# ./zkServer.sh start

到这一步完成了zookeeper环境的搭建

HBase环境搭建

解压缩hbase安装包

# tar -zxvf hbase-1.2.6-bin.star.gz -C /usr
# mkdir /usr/hbase-1.2.6-bin/logs

修改Hbase启动时要使用的环境变量(hbase-env.sh

-- 打开环境变量配置文件
# vim /usr/hbase-1.2.6/conf/hbase-env.sh

-- 添加如下内容
-- 1、设置java安装路径
export JAVA_HOME=/usr/java/jdk1.8.0_131
-- 2、设置hbase的日志地址
export HBASE_LOG_DIR=${HBASE_HOME}/logs
-- 3、设置是否使用hbase管理zookeeper(因使用zookeeper管理的方式,故此参数设置为false)
export HBASE_MANAGES_ZK=false
-- 4、设置hbase的pid文件存放路径
export HBASE_PID_DIR=/var/hadoop/pids

添加所有的region服务器到regionservers文件中

– 打开regionservers配置文件

# vim /usr/hbase-1.2.5/conf/regionservers

-- 删除localhost,新增如下内容
master
slave1
slave2

注:hbase在启动或关闭时会依次迭代访问每一行来启动或关闭所有的region服务器进程

修改Hbase集群的基本配置信息(hbase-site.xml),该配置将会覆盖Hbase的默认配置

-- 打开配置文件
# vim /usr/hbase-1.2.6/conf/hbase-site.xml

-- 在configuration节点下添加如下内容

<property>
    <name>hbase.rootdir</name>
    <value>hdfs://master:9000/hbase</value>
</property>
<property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
</property>
<property>
    <name>hbase.zookeeper.quorum</name>
    <value>master,slave1,slave2</value>
</property>
<property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/usr/zookeeper-3.4.10/data</value>
</property>
<property>
    <name>hbase.master</name>
    <value>hdfs://master:60000</value>
</property>

复制hbase到slave中

# scp -r /usr/hbase-1.2.6 slave1:/usr
# scp -r /usr/hbase-1.2.6 slave2:/usr

启动hbase(仅在master节点上执行即可)

# ssh master
# /usr/hbase-1.2.5/bin/start-hbase.sh

到这一步hbase环境搭建完成

本地测试

使用Habse shell连接Hbase

cd /usr/hbase-1.2.6/bin/
./hbase shell

创建user1表

create 'user1','personalinfo'

对user1简单CURD

插入

put 'user1','roow1','personalinfo:name','zhangsan'

put

查询

get 'user1','row1','personalinfo:name'

get

其他命令 help查询就好

hbase(main):001:0> help
HBase Shell, version 1.2.6, rUnknown, Mon May 29 02:25:32 CDT 2017
Type 'help "COMMAND"', (e.g. 'help "get"' -- the quotes are necessary) for help on a specific command.

SHELL USAGE:
Quote all names in HBase Shell such as table and column names.  Commas delimit
command parameters.  Type <RETURN> after entering a command to run it.
Dictionaries of configuration used in the creation and alteration of tables are
Ruby Hashes. They look like this:

  {'key1' => 'value1', 'key2' => 'value2', ...}

and are opened and closed with curley-braces.  Key/values are delimited by the
'=>' character combination.  Usually keys are predefined constants such as
NAME, VERSIONS, COMPRESSION, etc.  Constants do not need to be quoted.  Type
'Object.constants' to see a (messy) list of all constants in the environment.

If you are using binary keys or values and need to enter them in the shell, use
double-quote'd hexadecimal representation. For example:

  hbase> get 't1', "key\x03\x3f\xcd"
  hbase> get 't1', "key\003\023\011"
  hbase> put 't1', "test\xef\xff", 'f1:', "\x01\x33\x40"

The HBase shell is the (J)Ruby IRB with the above HBase-specific commands added.
For more on the HBase Shell, see http://hbase.apache.org/book.html
