HBase安装配置

HBase安装配置

 

HBase的安装有三种模式：单机模式、伪分布式模式、分布式模式。

其中，HBase在单机模式下不使用HSFS，直接将安装文件解压，改个hbase.xml文件就可以运行了；默认情况下HBAse数据是存储在根目录的tmp文件夹下，可以通过start-hbase.sh和stop-hbase.sh命令启动和关闭HBase；而伪分布式和分布式模式下的HBase需要HDFS系统；下面是按伪分布式进行安装配置HBase，配置好了三个集群：tjt01、tjt02、tjt03,hbase安装在tjt02机器上运行。

1、伪分布式安装

HBase下载，官网地址：http://hbase.apache.org/

这里下载的是hbase-1.2.6版本：hbase-1.2.6-bin.tar.gz

1.1 使用HBase自带的zookeeper

HBase使用zookeeper进行管理，HBase本身自带了一个zookeeper，So伪分布式安装可以直接使用HBase自带的zookeeper，无需单独安装zookeeper。

1.2 解压HBase

将HBase hbase-1.2.6版本解压到/usr/local目录下：

[[email protected] opt]# tar -zxvf hbase-1.2.6-bin.tar.gz -C /usr/local

将目录命名为hbase目录：

[[email protected] opt]# cd /usr/local/
[[email protected] local]# mv hbase-1.2.6 hbase

1.3 修改配置文件:

修改配置文件/usr/local/hbase/conf/hbase-en.sh

[[email protected] local]# vi /usr/local/hbase/conf/hbase-env.sh

修改内容如下：

export JAVA_HOME=/opt/jdk1.8.0_181
export HBASE_MANAGES_ZK=true

修改配置文件/usr/local/hbase/conf/hbase-site.xml

[[email protected] local]# vi /usr/local/hbase/conf/hbase-site.xml

增加如下配置：

<property>  
  <name>hbase.rootdir</name>  
  <value>hdfs://tjt01:9000/hbase</value>
</property>
<property>
  <name>hbase.cluster.distributed</name>
  <value>true</value>
</property>
<property>
  <name>hbase.zookeeper.quorum</name>
  <value>tjt02</value>
</property>
<property>
  <name>dfs.replication</name>   
  <value>1</value>
</property>

 1.4 PATH路径到添加

/etc/profile文件增加：export PATH=$PATH:/usr/local/hbase/bin

[[email protected] local]# vi /etc/profile
[[email protected] local]# source /etc/profile
[[email protected] local]# 

1.5 启动HBase

启动HBase之前记得启动hdfs，start-hdfs.sh

[[email protected] local]# start-hbase.sh
tjt02: starting zookeeper, logging to /usr/local/hbase/bin/../logs/hbase-root-zookeeper-tjt02.out
starting master, logging to /usr/local/hbase/bin/../logs/hbase-root-master-tjt02.out
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0
starting regionserver, logging to /usr/local/hbase/bin/../logs/hbase-root-1-regionserver-tjt02.out
[[email protected] local]# 

使用jps命令查看HBase是否启动成功：

HRegionServer、HQuorumPeer、HMaster

1.6 验证HBase

关闭机器tjt02的防火墙：

[[email protected] local]# systemctl stop firewalld
[[email protected] local]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[[email protected] local]#

访问HBase首页: http://172.16.114.131:16010/

使用HBase命令行再次验证：

[[email protected] local]# hbase shell

Now，HBase安装配置OK！
