1. 前言
之前我们已经搭建过了 hbase单点环境，(单机版搭建参见： https://blog.csdn.net/a15835774652/article/details/135569456)
但是 为了模拟一把集群环境 我们还是尝试搭建一个伪集群版
2. 环境准备
- jdk环境 1.8+
- hdfs （hadoop环境 可选） 搭建参考 https://blog.csdn.net/a15835774652/article/details/135572760
3. 配置
搭建过 hadoop 才发现 hbase环境配置如此之少 可能hadoop东西比较多的缘故
- 配置 jdk 修改 conf/hbase-env.sh
# 修改为自己的jdk export JAVA_HOME=/usr/local/develop/java/zulu-jdk17.0.7 #可选 jdk1.8 以上需要配置 export HBASE_OPTS="${HBASE_SHELL_OPTS} --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/sun.nio.ch=ALL-UNNAMED --add-opens java.base/java.io=ALL-UNNAMED" - 修改 conf/hbase-site.xml 新增属性配置
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<!--配置hbase存储目录 这是用hdfs方式 -->
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:8020/hbase</value>
</property>
<!--另外还可以选择本地目录方式 二选一即可 -->
<!-- <property>
<name>hbase.rootdir</name>
<value>file:///usr/local/develop/hbase</value>
</property> -->
<property>
<name>hbase.master.ipc.address</name>
<value>0.0.0.0</value>
</property>
<property>
<name>hbase.regionserver.ipc.address</name>
<value>0.0.0.0</value>
</property>
- 移除 hbase.tmp.dir 和 hbase.unsafe.stream.capability.enforce 配置
4. 启动
是的，你没有听错 配置到这就结束了。开始进入启动环节
直接输入命令进行启动
bin/start-hbase.sh
如果配置的没问题的话 使用jps 查看 可以看到 HMaster and HRegionServer 进程在运行
5. 检查hdfs中的 hbase目录
./bin/hadoop fs -ls /hbase
6. Start backup HBase Master
# 开启 3个 backup servers using ports 16002/16012, 16003/16013, and 16005/16015. 2 3 5每个参数是 相对默认端口16000的偏移量
bin/local-master-backup.sh start 2 3 5
然后我们可以访问本地的 hbase控制台试试效果
默认的是 localhost:16010
backup server localhost:16012 localhost:16013 localhost:16015
这样我们访问就有4个节点了 一个主节点 3个backup 节点 在通过一些组件例如keep alive 等 就实现了 多节点 高可用
7. 停止 backup HBase Master
要kill备用master而不杀死整个集群，需要找到其进程D（PID）。PID存储在文件中，名称为 /tmp/hbase-user-x-master.pid。文件的唯一内容是PID。您可以使用Kill -9命令杀死该PID。以下命令将使用端口偏移1杀死master，但使群集运行：
查看tmp目录下的 hbase backup master pid文件
选择对应的文件 并执行如下命令 即可kill 备用的 master
#注意hbase-leon-2-master.pid n替换为自己的pid文件
cat /tmp/hbase-leon-2-master.pid |xargs kill -9
8. 开启 备用的RegionServers
设置环境变量 /conf/hbase-env.sh
export HBASE_RS_BASE_PORT=16020
export HBASE_RS_INFO_BASE_PORT=16030
Hnegionserver按照HMaster指示管理其仓库中的数据。通常，一个hregionserver在集群中的每个节点运行。在同一系统上运行多个Hegionservers在伪分布模式下测试很有用。local-regionservers.sh命令允许您运行多个RegionServer。它以与local-master-backup.sh命令相似的方式工作，因为您提供的每个参数代表一个实例的端口偏移。每个区域服务器需要两个端口，默认端口为16020和16030。由于HBASE版本1.1.0，HMASTER不使用区域服务器端口，因此将10个端口（16020至16029和16029和16030至16039）用于ZEMIONIONSERVERS。为了支持其他区域服务器，设置环境变量HBASE_RS_BASE_PORT和HBASE_RS_INFO_BASE_PORT在运行脚本local-regionservers.sh之前。例如对于基本端口的值16200和16300，服务器上可以支持99个其他区域服务器。以下命令启动了另外三个区域服务器，从16022/16032（基本端口16020/16030加2）运行。
开启3个 RegionServers
# regionServers 默认端口为16020和16030
# 参数2 3 5 含义是相对默认端口的偏移量
./bin/local-regionservers.sh start 2 3 5
9. 停止 localRegionServers
./bin/local-regionservers.sh stop 3
以上就完成了 hbase的伪集群搭建 其中 master的 backup比较好配置 另外 多个regionServers 配置稍微复杂。
10. 问题记录
- 问题一 ip绑定问题
hbase 启动服务默认绑定ip到 自己电脑的IP地址上 而没有绑定到localhost 但是在hbase的shell工具中 默认连接的地址是localhost 然后报错提示 连接不到localhost的16000端口 报错如下
list 'test'

难道说 hbase不能绑定到0.0.0.0上
折中解决先把IP绑定到 localhost 上 或者127.0.0.1上 然后使用hbase shell测试

这个问题导致hbase无法完成启动，只能被迫换了使用hdfs
good day ！！！
