HBase安装配置
①下载压缩包(选择与自己安装的Hadoop版本的兼容版本,见后面附录)
官网下载地址:https://mirrors.tuna.tsinghua.edu.cn/apache/hbase/stable/
选择稳定版hbase-1.4.9-bin.tar.gz,在Windows里面下载。
②将压缩包从Windows传输到Linux当前目录下
SecureCRT 【File】→【Connect SFTP Session】开启sftp操作
③安装
解压安装到指定目录下/opt/module(/opt是系统自带目录,之下的/module是自己创建的)
④配置环境变量
在/etc/profile文件里添加HBase安装路径的配置信息,之后用source命令使配置生效。安装之后的目录为hbase-1.4.9,修改为hbase,所以我的HBase安装路径是/opt/module/hbase。
测试HBase安装成功,命令hbase version,或hbase。
HBase配置(伪分布式模式)
配置文件位于HBase安装路径的conf目录(/opt/module/hbase/conf)下面
①配置hbase-env.sh
设置Java安装路径
设置HBase的配置文件路径(/opt/module/hbase/conf)
采用HBase自带Zookeeper,设置参数true
②配置hbase-site.xml
hbase.rootdir
hdfs://bigdata128:9000/hbase
hbase.cluster.distributed
true
hbase.zookeeper.quorum
localhost
③启动并运行HBase(之前启动Hadoop)
启动HBase,并jps查看
用完停止HBase运行(之后停止Hadoop)
进入HBase数据库
进入HBase的shell命令行模式
了解命令使用方法,如创建表,输入help ‘create’
①创建表
③查看数据
删除一个单元格
删除一行
