# 阿里云ecs搭建
#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
## 修改hosts文件
分别登陆三台主机，修改hosts
```
vim /etc/hosts
--添加一下信息（三台都要改）
10.30.45.239 master
10.31.155.33 slave1
10.81.233.67 slave2
```
## 登陆master，下载所有安装包

## 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
```
## 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
```

```
## 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
hbase.rootdir
hdfs://master:9000/hbase
hbase.cluster.distributed
true
hbase.zookeeper.quorum
master,slave1,slave2
hbase.zookeeper.property.dataDir
/usr/zookeeper-3.4.10/data
hbase.master
hdfs://master:60000
```
## 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'
`
### 查询
`get 'user1','row1','personalinfo:name'
`
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

SHELL USAGE:
Quote all names in HBase Shell such as table and column names. Commas delimit
command parameters. Type 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
