3.6 Zookeeper安装及环境配置
3.6.1 Zookeeper安装
安装文件解压到/opt/zookeeper路径下。
[root@master ~]# tar -xvf zookeeper-3.4.10.tar.gz
[root@master ~]# mv zookeeper-3.4.10 /opt/zookeeper
[root@master ~]# mv zookeeper-3.4.10 zookeeper3.4
在zookeeper路径下创建数据文件和日志文件。
[root@master ~]# mkdir /opt/zookeeper/data
[root@master ~]# mkdir /opt/zookeeper/log
# 在/opt/zookeeper/data目录下创建myid文件
[root@master ~]# touch myid
[root@master ~]# vi myid
# 设定值为1
1
修改zoo.cfg文件。
[root@master ~]# cd /opt/zookeeper/zookeeper3.4/conf
# 创建zoo.cfg文件
[root@master conf]# cp zoo_sample.cfg zoo.cfg
[root@master conf]# vi zoo.cfg
具体修改如下所示：
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
#dataDir=/tmp/zookeeper
# the port at which the clients will connect
# 默认端口是2181，但本机端口被占用，遂变更为2381
clientPort=2381
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
quorumListenOnAllIPs=ture
# 新增内容
dataDir=/opt/zookeeper/data
dataLogDir=/opt/zookeeper/log
server.1=master:2888:3888
server.2=slave1:2888:3888
server.3=slave2:2888:3888
将Zookeeper传递给slave1和slave2，/opt/zookeeper/data路径下的myid与zoo.cfg内容须保持一致。
[root@master conf]# scp -r /opt/zookeeper root@slave1:/opt
[root@master conf]# scp -r /opt/zookeeper root@slave2:/opt
3.6.2 Zookeeper环境配置
编辑环境变量。
[root@master ~]# vi /etc/profile
修改内容如下：
export ZK_HOME=/opt/zookeeper/zookeeper3.4
PATH=$PATH:${JAVA_HOME}/bin:$HADOOP_HOME/sbin:$HADOOP_HOME/bin:${SCALA_HOME}/bin:${SPARK_HOME}/bin:${ZK_HOME}/bin:$PATH
使修改生效。
[root@master ~]# source /etc/profile
3.6.3 Zookeeper启动
完成Zookeeper的安装配置后，在每一台机器上启动。注：Zookeeper遵循选举制
slave1
[root@slave1 ~]# cd /opt/zookeeper/zookeeper3.4/bin
[root@slave1 bin]# ./zkServer.sh start

3.7 HBase安装及环境配置
3.7.1 HBase安装
将HBase安装包加载至/opt/HBase路径下，并将其解压到当前路径。
[root@master ~]# mkdir /opt/HBase
[root@master ~]# cd /opt/HBase
[root@master HBase]# rz
rz waiting to receive.

[root@master ~]# tar -xvf hbase-2.0.2-bin.tar.gz
3.7.2 配置文件修改
切换到/opt/hbase/hbase-2.0.2/conf路径。
在这里插入图片描述
修改hbase-env.sh，在文件中添加以下配置。
export JAVA_HOME=/opt/java/jdk1.8.0_181
export HADOOP_HOME=/opt/hadoop/hadoop-2.7.2
export HBASE_HOME=/opt/HBase/hbase-2.0.2
export HBASE_CLASSPATH=/opt/hadoop/hadoop-2.7.2/etc/hadoop
export HBASE_PID_DIR=/root/hbase/pids
export HBASE_MANAGES_ZK=false
修改hbase-site.xml，在文件中添加以下配置。
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://master:9000/hbase</value>
<description>The directory shared byregion servers.</description>

<value>true</value>
</property>
<!-- 指定master -->
<property>
<name>hbase.master</name>
<value>master:60000</value>
</property>
</configuration>
修改regionservers，指定hbase的主从。
master
slave1
slave2
将这些配置传输到其他机器上。
scp -r /opt/HBase root@slave1:/opt
scp -r /opt/HBase root@slave2:/opt
配置环境变量。
[root@master ~]# vi /etc/profile
配置文件内容如下所示：
export HBASE_HOME=/opt/HBase/hbase-2.0.2
export PATH=$PATH:${JAVA_HOME}/bin:$HADOOP_HOME/sbin:$HADOOP_HOME/bin:${SCALA_HOME}/bin:${SPARK_HOME}/bin:${ZK_HOME}/bin:${HBASE_HOME}/bin:$PATH
使配置文件生效。
[root@master ~]# source /etc/profile
查看安装结果。
[root@master ~]# hbase version

3.7.3 启动HBase
Hbase是基于hadoop提供的分布式文件系统的，所以启动Hbase之前，先确保hadoop在正常运行，另外Hbase还依赖于zookkeeper，本来我们可以用hbase自带的zookeeper，但是我们上面的配置启用的是我们自己的zookeeper集群，所以在启动hbase前，还要确保zokeeper已经正常运行。Hbase可以只在hadoop的某个namenode节点上安装，也可以在所有的hadoop节点上安装，但是启动的时候只需要在一个节点上启动就行了，本例中，我在master、slave1、slave2都安装了Hbase，启动的时候只需要在master上启动就OK。

3.8 Hive安装及环境配置
Hive可以选择只安装在master节点上，而不必每一台都部署。
3.8.1 Mysql安装
由于mysql是Hive默认的元数据，所以需先行安装Mysql。
# 检查是否已安装mysql

export PATH=$PATH:${JAVA_HOME}/bin:$HADOOP_HOME/sbin:$HADOOP_HOME/bin:${SCALA_HOME}/bin:${SPARK_HOME}/bin:${HIVE_HOME}/bin:${ZK_HOME}/bin:${HBASE_HOME}/bin:$PATH
[root@master ~]# source /etc/profile
建立必需的文件夹。
# 建立root目录下需要的文件夹
[root@master ~]# mkdir /root/hive
[root@master ~]# mkdir /root/hive/warehouse
# hadoop下新建文件目录
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -mkdir -p /root/hive/
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -mkdir -p /root/hive/warehouse
# 为新建文件目录授权读写能力
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -chmod 777 /root/hive/
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -chmod 777 /root/hive/warehouse
# 检验创建状态
