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
ZooKeeper JMX enabled by default

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。
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。
hbase.rootdir
hdfs://master:9000/hbase
The directory shared byregion servers.
hbase.zookeeper.property.clientPort
2181
zookeeper.session.timeout
120000
hbase.master.maxclockskew
150000
hbase.zookeeper.quorum
master,slave3,slave4
hbase.tmp.dir
/root/hbase/tmp
hbase.cluster.distributed
true
hbase.master
master:60000
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

3.8.2 Hive环境配置
设置环境变量。
[root@master ~]# vi /etc/profile
export HIVE_HOME=/opt/hive/apache-hive-2.3.4-bin
export HIVE_CONF_DIR=${HIVE_HOME}/conf
export PATH=$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
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -ls /root/
[root@master ~]# $HADOOP_HOME/bin/hadoop fs -ls /root/hive/
修改hive-site.xml
。
# 创建hive-site.xml
[root@master ~]# cd /opt/hive/apache-hive-2.3.4-bin/conf
[root@master conf]# cp hive-default.xml.template hive-site.xml
[root@master conf]# vi hive-site.xml
添加内容如下:
hive.metastore.warehouse.dir
/root/hive/warehouse
hive.exec.scratchdir
/root/hive
hive.metastore.uris
javax.jdo.option.ConnectionURL
jdbc:mysql://master:3306/hive?createDatabaseIfNotExist=true
javax.jdo.option.ConnectionDriverName
com.mysql.jdbc.Driver
javax.jdo.option.ConnectionUserName
root
javax.jdo.option.ConnectionPassword
123456
hive.metastore.schema.verification
false
将配置文件中所有的${system:java.io.tmpdir}
更改为 /opt/hive/tmp
(如果没有该文件则创建),并将此文件夹赋予读写权限,将${system:user.name}
更改为 root
。
hive.exec.local.scratchdir
/opt/hive/tmp/root
Local scratch space for Hive jobs
hive.downloaded.resources.dir
/opt/hive/tmp/${hive.session.id}_resources
Temporary local directory for added resources in the remote file system.
修改 hive-env.sh
。
[root@master ~]# cd /opt/hive/apache-hive-2.3.4-bin/conf
[root@master conf]# cp hive-env.sh.template hive-env.sh
[root@master conf]# vi hive-env.sh
# 添加以下内容
export HADOOP_HOME=/opt/hadoop/hadoop-2.7.2
export HIVE_CONF_DIR=/opt/hive/apache-hive-2.3.4-bin/conf
export HIVE_AUX_JARS_PATH=/opt/hive/apache-hive-2.3.4-bin/lib
添加数据驱动包
首先从mysql官网下载对应的JDBC安装包。
[root@master ~]# cd /opt/hive/apache-hive-2.3.4-bin/lib
# 下载mysql 的 jdbc连接驱动jar包,放到hive的lib目录下
