HBase部署

1|0HBase部署-基于Hbase自带的Zookeeper

1|1时间同步

 
#查看三台主机时间是否同步，可容忍5秒内偏差
[root@master ~]# for i in master slave1 slave2;do ssh root@$i 'date';done
Thu Apr  6 17:26:38 CST 2023
Thu Apr  6 17:26:38 CST 2023
Thu Apr  6 17:26:38 CST 2023

#若要实现时间同步，则安装ntpdate包
[root@master ~]# yum -y install ntpdate
#执行命令
[root@master ~]# ntpdate time1.aliyun.com

#注意三个节点都要做

1|2解压安装包，改名

 
[root@master ~]# ls
apache-hive-2.0.0-bin.tar.gz  mysql
hadoop-2.7.1.tar.gz           mysql-5.7.18.zip
hbase-1.2.1-bin.tar.gz        mysql-connector-java-5.1.46.jar
jdk-8u152-linux-x64.tar.gz    zookeeper-3.4.8.tar.gz
[root@master ~]# tar xf hbase-1.2.1-bin.tar.gz -C /usr/local/src
[root@master ~]# cd /usr/local/src/
[root@master src]# ls
hadoop  hbase-1.2.1  hive  jdk  zookeeper
[root@master src]# mv hbase-1.2.1 hbase
[root@master src]# ls
hadoop  hbase  hive  jdk  zookeeper
[root@master ~]# cd /usr/local/src/hbase/conf/
[root@master conf]# ls
hadoop-metrics2-hbase.properties  hbase-env.sh      hbase-site.xml    regionservers
hbase-env.cmd                     hbase-policy.xml  log4j.properties

1|3配置hbase环境变量

 
#创建hbase.sh文件
[root@master ~]# vi /etc/profile.d/hbase.sh

#添加如下内容
export HBASE_HOME=/usr/local/src/hbase
export PATH=${HBASE_HOME}/bin:$PATH

#进入/usr/local/src/hbase/conf/目录，在文件hbase-env.sh中修改以下内容
export JAVA_HOME=/usr/local/src/jdk
export HBASE_CLASSPATH=/usr/local/src/hadoop/etc/hadoop
export HBASE_MANAGES_ZK=true
#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"

1|4在master节点配置hbase-site.xml

 
[root@master conf]# vi hbase-site.xml 
#在<configuration></configuration>添加
<configuration>
        <property>
                <name>hbase.rootdir</name>
                <value>hdfs://master:9000/hbase</value>
        </property>
        <property>
                <name>hbase.master.info.port</name>
                <value>60010</value>
        </property>
        <property>
                <name>hbase.zookeeper.property.clientPort</name>
                <value>2181</value>
        </property>
        <property>
                <name>zookeeper.session.timeout</name>
                <value>120000</value>
        </property>
        <property>
                <name>hbase.zookeeper.quorum</name>
                <value>master,slave1,slave2</value>
        </property>
        <property>
                <name>hbase.tmp.dir</name>
                <value>/usr/local/src/hbase/tmp</value>
        </property>
        <property>
                <name>hbase.cluster.distributed</name>
                <value>true</value>
        </property>
</configuration>

1|5在master节点修改 regionservers文件

 
[root @master conf]$ vi regionservers 
#删除 localhost，每一行写一个 slave 节点主机机器名
slave1
slave2

1|6在 master 节点创建hbase.tmp.dir目录

 
[root@master hbase]# mkdir /usr/local/src/hbase/tmp
[root@master hbase]# ls
bin  CHANGES.txt  conf  docs  hbase-webapps  LEGAL  lib  LICENSE.txt  NOTICE.txt  README.txt  tmp

1|7将 master上的 hbase 安装文件同步到 slave1 slave2

 
[root@master ~]# scp -r /usr/local/src/hbase/ root@slave1:/usr/local/src/
[root@master ~]# scp -r /usr/local/src/hbase/ root@slave2:/usr/local/src/

1|8在所有节点修改hbase 目录权限
