HBase-HBase安装部署 - HBase - 大数据学习笔记 | Aayu Yain = 学无止境 = 世界上大部分事，都没太大意义。真理与热爱除外

# 环境

在之前完成 Hadoop 完全分布式安装和部署的服务器上继续完成 HBase 的安装和部署，不了解的朋友可看：

# Zookeeper 正常部署

首先保证 Zookeeper 集群正常部署并启动之：

	[root@hadoop02 zookeeper-3.4.10]# zkServer.sh start
	[root@hadoop03 zookeeper-3.4.10]# zkServer.sh start
	[root@hadoop04 zookeeper-3.4.10]# zkServer.sh start

# Hadoop 正常部署

Hadoop 集群的正常部署并启动：

	[root@hadoop02 hadoop-2.7.2]# start-dfs.sh
	Starting namenodes on [hadoop02]
	hadoop02: starting namenode, logging to /opt/module/hadoop-2.7.2/logs/hadoop-root-namenode-hadoop02.out
	hadoop02: starting datanode, logging to /opt/module/hadoop-2.7.2/logs/hadoop-root-datanode-hadoop02.out
	hadoop03: starting datanode, logging to /opt/module/hadoop-2.7.2/logs/hadoop-root-datanode-hadoop03.out
	hadoop04: starting datanode, logging to /opt/module/hadoop-2.7.2/logs/hadoop-root-datanode-hadoop04.out
	Starting secondary namenodes [hadoop04]
	hadoop04: starting secondarynamenode, logging to /opt/module/hadoop-2.7.2/logs/hadoop-root-secondarynamenode-hadoop04.out

	[root@hadoop03 hadoop-2.7.2]# start-yarn.sh
	starting yarn daemons
	starting resourcemanager, logging to /opt/module/hadoop-2.7.2/logs/yarn-root-resourcemanager-hadoop03.out
	hadoop03: starting nodemanager, logging to /opt/module/hadoop-2.7.2/logs/yarn-root-nodemanager-hadoop03.out
	hadoop02: starting nodemanager, logging to /opt/module/hadoop-2.7.2/logs/yarn-root-nodemanager-hadoop02.out
	hadoop04: starting nodemanager, logging to /opt/module/hadoop-2.7.2/logs/yarn-root-nodemanager-hadoop04.out

注意：YARN 需要在 hadoop03 服务器上启动，因为 resourcemanager 部署在 hadoop03 上。

# HBase 解压

[root@hadoop02 software]# tar -zxvf hbase-1.3.1-bin.tar.gz -C /opt/module/

# HBase 的配置文件

修改 hbase 对应的配置文件

conf/hbase-env.sh 修改内容

# 第27行
export JAVA_HOME=/opt/module/jdk1.8.0_144

# 下面这两行原本是打开的，用 # 将它们注释
#export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS -XX:PermSize=128m -XX:MaxPermSize=128m"
#export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -XX:PermSize=128m -XX:MaxPermSize=128m"

# 第128行
export HBASE_MANAGES_ZK=false

conf/hbase-site.xml 修改内容

	<configuration>
	<property>
	<name>hbase.rootdir</name>
	<value>hdfs://hadoop02:9000/HBase</value>
	</property>

	<property>
	<name>hbase.cluster.distributed</name>
	<value>true</value>
	</property>

	<!-- 0.98 后的新变动，之前版本没有.port, 默认端口为 60000 -->
	<property>
	<name>hbase.master.port</name>
	<value>16000</value>
	</property>

	<property>
	<name>hbase.zookeeper.quorum</name>
	<value>hadoop02,hadoop03,hadoop04</value>
	</property>

	<property>
	<name>hbase.zookeeper.property.dataDir</name>
	<value>/opt/module/zookeeper-3.4.10/zkData</value>
	</property>
	</configuration>

修改 conf/regionservers

hadoop02
hadoop03
hadoop04

软连接 hadoop 配置文件到 HBase：

[root@hadoop02 module]# ln -s /opt/module/hadoop-2.7.2/etc/hadoop/core-site.xml /opt/module/hbase-1.3.1/conf/core-site.xml

[root@hadoop02 module]# ln -s /opt/module/hadoop-2.7.2/etc/hadoop/hdfs-site.xml /opt/module/hbase-1.3.1/conf/hdfs-site.xml

配置文件同步到其他集群

[root@hadoop02 hbase-1.3.1]# xsync conf/

# HBase 服务的启动

启动方式一：单节点启动

	[root@hadoop02 hbase-1.3.1]# bin/hbase-daemon.sh start master
	starting master, logging to /opt/module/hbase-1.3.1/bin/../logs/hbase-root-master-hadoop02.out
	[root@hadoop02 hbase-1.3.1]# bin/hbase-daemon.sh start regionserver
	starting regionserver, logging to /opt/module/hbase-1.3.1/bin/../logs/hbase-root-regionserver-hadoop02.out

	[root@hadoop02 hbase-1.3.1]# jps
	20084 HMaster
	20340 HRegionServer
	20424 Jps
	19500 NodeManager
	11037 QuorumPeerMain
	19261 DataNode
	19133 NameNode

可以看到服务正常启动。也可以访问 web 界面

http://hadoop02:16010/master-status

注意：如果集群之间的节点时间不同步，会导致 regionserver 无法启动，抛出 ClockOutOfSyncException 异常。解决办法是同步服务器的时间

启动方式二：群起

[root@hadoop02 hbase-1.3.1]# bin/start-hbase.sh

对应的停止服务

[root@hadoop02 hbase-1.3.1]# bin/stop-hbase.sh

HBase
