说明：不少读者反馈，想使用开源组件搭建Hadoop平台，然后再部署Kylin，但是遇到各种问题。这里我为读者部署一套环境，请朋友们参考一下。如果还有问题，再交流。

系统环境以及各组件版本信息

Linux操作系统：

cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)

JDK版本：

java -version

java version "1.8.0_111"

Java(TM) SE Runtime Environment (build1.8.0_111-b14)

Java HotSpot(TM) 64-Bit Server VM (build25.111-b14, mixed mode)

Hadoop组件版本：

Hive：apache-hive-1.2.1-bin

Hadoop：hadoop-2.7.2

HBase：hbase-1.1.9-bin

Zookeeper：zookeeper-3.4.6

Kylin版本：

apache-kylin-1.5.4.1-hbase1.x-bin

三个节点情况以及安装的组件（仅测试）：

192.168.1.129 ldvl-kyli-a01 ldvl-kyli-a01.idc.dream.com

192.168.1.130 ldvl-kyli-a02 ldvl-kyli-a02.idc.dream.com

192.168.1.131 ldvl-kyli-a03 ldvl-kyli-a03.idc.dream.com

基础组件部署

```
 JDK环境搭建（3个节点）
```

rpm包安装：

rpm -ivh jdk-8u111-linux-x64.rpm

配置环境变量：

vi /etc/profile

export JAVA_HOME=/usr/java/default

export JRE_HOME=/usr/java/default/jre

exportCLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH

exportPATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

source /etc/profile

验证：

java -version

java version "1.8.0_111"

Java(TM) SE Runtime Environment (build1.8.0_111-b14)

Java HotSpot(TM) 64-Bit Server VM (build25.111-b14, mixed mode)

```
 Zookeeper环境搭建（3个节点）
```

安装：

tar -zxvf zookeeper-3.4.6.tar.gz -C /usr/local/

cd /usr/local/

ln -s zookeeper-3.4.6 zookeeper

创建数据和日志目录

mkdir /usr/local/zookeeper/zkdata

mkdir /usr/local/zookeeper/zkdatalog

配置Zookeeper参数

cd /usr/local/zookeeper/conf

cp zoo_sample.cfg zoo.cfg

修改好的配置文件如下：

tickTime=2000

initLimit=10

syncLimit=5

dataDir=/usr/local/zookeeper/zkdata

dataLogDir=/usr/local/zookeeper/zkdatalog

clientPort=2181

server.1=ldvl-kyli-a01:2888:3888

server.2=ldvl-kyli-a02:2888:3888

server.3=ldvl-kyli-a03:2888:3888

创建myid

cd /usr/local/zookeeper/zkdata

echo 1 > myid #每个节点根据上面的配置（server.x）创建对应的文件内容

启动Zookeeper：

zkServer.sh start

查看状态：

192.168.1.129节点：

zkServer.sh status

JMX enabled by default

Using config:/usr/local/zookeeper/bin/../conf/zoo.cfg

Mode: follower

192.168.1.130节点：

zkServer.sh status

JMX enabled by default

Using config:/usr/local/zookeeper/bin/../conf/zoo.cfg

Mode: leader

192.168.1.131节点：

zkServer.sh status

JMX enabled by default

Using config:/usr/local/zookeeper/bin/../conf/zoo.cfg

Mode: follower

```
 MariaDB数据库
```

安装：

yum install MariaDB-server MariaDB-client

启动：

systemctl start mariadb

设置root密码，安全加固等：

mysql_secure_installation

```
 关闭防火墙
```

systemctl disable firewalld

systemctl stop firewalld

同时，也需要关闭SELinux，可修改 /etc/selinux/config 文件，将其中的 SELINUX=enforcing 改为 SELINUX=disabled即可。

```
 三个节点保证时间同步
```

可以通过ntp服务进行设置

Hadoop组件部署

```
 Hadoop
```

创建组和用户：

groupadd hadoop

useradd -s /bin/bash -d /app/hadoop -m hadoop-g hadoop

passwd hadoop

下面所有的操作都是在hadoop用户下面操作

切换到hadoop用户下面创建信任关系：

ssh-keygen -t rsa

ssh-copy-id -p 22 hadoop@192.168.1.129

ssh-copy-id -p 22 hadoop@192.168.1.130

ssh-copy-id -p 22 hadoop@192.168.1.131

解压缩：

$ tar -zxvf hadoop-2.7.2.tar.gz

设置软链接：

$ ln -s hadoop-2.7.2 hadoop

配置：

$ cd /app/hadoop/hadoop/etc/hadoop

l hadoop-env.sh，mapred-env.sh和yarn-env.sh

export JAVA_HOME=/usr/java/default

环境变量配置（这里我将所有的组件的环境变量都配置好了，后面每个组件我就不再说明）：

$ cat .bashrc

export JAVA_HOME=/usr/java/default

export JRE_HOME=/usr/java/default/jre

exportCLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH

export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

export HIVE_HOME=/app/hadoop/hive

export HADOOP_HOME=/app/hadoop/hadoop

export HBASE_HOME=/app/hadoop/hbase

added by HCAT

export HCAT_HOME=/app/hadoop/hive/hcatalog

added by Kylin

export KYLIN_HOME=/app/hadoop/kylin

export KYLIN_CONF=/app/hadoop/kylin/conf

exportPATH=$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HIVE_HOME/bin:$HBASE_HOME/bin:${KYLIN_HOME}/bin:$PATH

创建HDFS的数据目录

$ mkdir -p /app/hadoop/hdfs/data

$ mkdir -p /app/hadoop/hdfs/name

$ mkdir -p /app/hadoop/tmp

加入上面的hadoop所有配置都配置完成了，你也可以全部拷贝到其他节点。

HDFS格式化：

$ hdfs namenode -format

$ start-dfs.sh

$ start-yarn.sh

$ mr-jobhistory-daemon.sh starthistoryserver

然后进行验证操作，比如同通过jps查看进程，通过web页面服务hdfs和yarn，执行wordcount的测试程序等等

Hive组件部署

安装：

$ tar -zxvf apache-hive-1.2.1-bin.tar.gz

$ ln -s apache-hive-1.2.1-bin hive

</property>

</configuration>

l hive-log4j.properties

hive.log.dir=/app/hadoop/hive/log

hive.log.file=hive.log

将mysql-connector-java-5.1.38-bin.jar放到Hive的lib目录下面：

$ cp mysql-connector-java-5.1.38-bin.jar/app/hadoop/hive/lib/

创建Hive元数据库：

MariaDB [(none)]> create database metastore character set latin1;

grant all on metastore.* to hive@"%" identified by "123456" with grant option;

flush privileges;

启动服务：

nohup hive --service metastore -v &

$ tailf nohup.out

Starting Hive Metastore Server

17/03/16 14:10:29 WARN conf.HiveConf:HiveConf of name hive.metastore.local does not exist

Starting hive metastore on port 9083

HBase组件部署

安装：

$ tar -zxvf hbase-1.1.9-bin.tar.gz

如果日志目录不存在，需要提前创建好。

启动HBase服务：

$ start-hbase.sh

Kylin环境部署（我只选第一个节点安装，仅测试）

安装：

$ tar -zxvf apache-kylin-1.5.4.1-hbase1.x-bin.tar.gz

$ ln -s apache-kylin-1.5.4.1-hbase1.x-bin kylin

配置：

$ cd kylin/conf/

环境检查没有问题，开始启动Kylin服务：

kylin.sh start

导入样例：

$ sample.sh

然后通过Kylin的Web页面重新加载元数据，然后构建Cube就可以查询了：

查询：

select part_dt, sum(price) as total_selled,count(distinct seller_id) as sellers from kylin_sales group by part_dt order bypart_dt
