HBase的安装部署
部署HBase必须配置先部署好 JDK、Hadoop、Zookeeper，配置3台服务器就要加，启动只需要启动028即可
1、配置环境变量
[bxwl@snode028 hbase-2.4.11]$ cat /etc/profile.d/bxwl.sh
export JAVA_HOME=/opt/jdk1.8.0_291
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export HADOOP_HOME=/opt/hadoop-3.3.2
#export HADOOP_CONF_DIR=/opt/hadoop-3.3.2/etc
export HBASE_HOME=/opt/hbase-2.4.11
export HBASE_CONF_DIR=${HBASE_HOME}/conf
export PATH=${JAVA_HOME}/bin:${HADOOP_HOME}/bin:${HBASE_HOME}/bin:$PATH
2、配置hbase-env.sh
HBase不使用自带的Zookeeper。这里其实都是配置环境变量，在上一步其实也可以完成。可以试试
[bxwl@snode028 hbase-2.4.11]$ cd conf
[bxwl@snode028 conf]$ vim hbase-env.sh
export HBASE_MANAGES_ZK=false
3、配置hbase-site.xml
[bxwl@snode028 conf]$ vim hbase-site.xml
<configuration>
<!--The following properties are set for running HBase as a single process on a
developer workstation. With this configuration, HBase is running in
"stand-alone" mode and without a distributed file system. In this mode, and
without further configuration, HBase and ZooKeeper data are stored on the
local filesystem, in a path under the value configured for `hbase.tmp.dir`.
This value is overridden from its default value of `/tmp` because many
systems clean `/tmp` on a regular basis. Instead, it points to a path within
this HBase installation directory.
Running against the `LocalFileSystem`, as opposed to a distributed
filesystem, runs the risk of data integrity issues and data loss. Normally
HBase will refuse to run in such an environment. Setting
`hbase.unsafe.stream.capability.enforce` to `false` overrides this behavior,
permitting operation. This configuration is for the developer workstation
only and __should not be used in production!__

</property>
<property>

<value>filesystem</value>
</property>
</configuration>
4、配置regionservers
[bxwl@snode028 conf]$ vim regionservers
snode028
snode029
snode030
5、软连接 hadoop 配置文件到 HBase
[bxwl@snode028 conf]$ ln -s /opt/hadoop-3.3.2/etc/hadoop/core-site.xml /opt/hbase-2.4.11/conf/core-site.xml
[bxwl@snode028 conf]$ ln -s /opt/hadoop-3.3.2/etc/hadoop/hdfs-site.xml /opt/hbase-2.4.11/conf/hdfs-site.xml
6、启动关闭HBase
// 启动
[bxwl@snode028 hbase-2.4.11]$ bin/start-hbase.sh
[bxwl@snode028 hbase-2.4.11]$ ~/bin/jpsall

[bxwl@snode028 hbase-2.4.11]$
// 关闭
[bxwl@snode028 hbase-2.4.11]$ bin/stop-hbase.sh
