zookeeper和hbase安装

321312

一、zookeeper
1、/etc/profile

HADOOP_PREFIX=/opt/hadoop
JAVA_HOME=/opt/jdk18
ZOOKEEPER_HOME=/opt/zookeeper
HBASE_HOME=/opt/hbase

PATH=$PATH:$JAVA_HOME/bin:$HADOOP_PREFIX/bin:$HADOOP_PREFIX/sbin:$ZOOKEEPER_HOME/bin:$HBASE_HOME/bin

export HADOOP_PREFIX PATH JAVA_HOME ZOOKEEPER_HOME HBASE_HOME USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL


2、创建目录:
mkdir -p /opt/zookeeper/data
mkdir -p /opt/zookeeper/logs
3、修改zoo.cfg配置文件，在在文件末尾添加。

server.1=NameNode34:2888:3888
server.2=DataNode35:2888:3888
server.3=DataNode37:2888:3888
server.4=DataNode38:2888:3888
dataDir=/opt/zookeeper/data
dataLogDir=/opt/zookeeper/logs

4、创建myid文件
在dataDir目录下创建myid文件，该文件的内容根据server定义的不同而不同，如server.1 该文件的内容是1，server.2 该文件内容是 2，以此类推.
节点1
echo "1">myid
节点2
echo "2">myid
节点3
echo "3">myid
节点4
echo "4">myid

5、拷贝至其他节点
scp /etc/profile root@DataNode35:/etc/profile
scp /etc/profile root@DataNode37:/etc/profile
scp /etc/profile root@DataNode38:/etc/profile

scp -r /opt/zookeeper root@DataNode35:/opt
scp -r /opt/zookeeper root@DataNode37:/opt
scp -r /opt/zookeeper root@DataNode38:/opt

6、在每个节点上
source /etc/profile

7、在每个节点上执行 zkServer.sh start
JMX enabled by default
Using config: /usr1/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

1.8 验证
[hadoop1@node4 bin]$ ./zkServer.sh status
JMX enabled by default
Using config: /usr1/zookeeper/bin/../conf/zoo.cfg
Mode: leader
[hadoop1@node1 bin]$ ./zkServer.sh status
JMX enabled by default
Using config: /usr1/zookeeper/bin/../conf/zoo.cfg
Mode: follower
[hadoop1@node2 bin]$ ./zkServer.sh status
JMX enabled by default
Using config: /usr1/zookeeper/bin/../conf/zoo.cfg
Mode: follower
[hadoop1@node3 bin]$ ./zkServer.sh status
JMX enabled by default
Using config: /usr1/zookeeper/bin/../conf/zoo.cfg
Mode: follower

-- The End --

二、hbase
1、下载hbase

2、/etc/profile

HADOOP_PREFIX=/opt/hadoop

JAVA_HOME=/opt/jdk18

ZOOKEEPER_HOME=/opt/zookeeper

HBASE_HOME=/opt/hbase

PATH=$PATH:$JAVA_HOME/bin:$HADOOP_PREFIX/bin:$HADOOP_PREFIX/sbin:$ZOOKEEPER_HOME/bin:$HBASE_HOME/bin

export HADOOP_PREFIX PATH JAVA_HOME ZOOKEEPER_HOME HBASE_HOME USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL

3、修改配置文件/opt/hbase/conf/hbase-env.sh
export JAVA_HOME=/opt/jdk18/
export HBASE_CLASSPATH=/opt/hbase/conf
export HBASE_MANAGES_ZK=true

4、在hbase安装目录下建立tmp文件夹
mkdir tmp

5、修改hbase-site.xml
<configuration>
<property>
    <name>hbase.rootdir</name>
    <value>hdfs://NameNode34:9000/hbase</value>
</property>
  <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
</property>
<property>
    <name>hbase.tmp.dir</name>
    <value>/opt/hbase/tmp</value>
</property>
<property>
    <name>hbase.zookeeper.quorum</name>
    <value>NameNode34,DataNode35,DataNode37,DataNode38</value>
</property>
<property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/opt/hbase/tmp/zookeeper</value>
</property>
</configuration>

6、编辑/opt/hbase/conf/regionservers，将所有的slavenode添加到这个文件
NameNode34
DataNode35
DataNode37
DataNode38

7、将Hbase拷贝到其他节点机并对其他节点机配置环境变量

scp /etc/profile root@DataNode35:/etc/profile

scp /etc/profile root@DataNode37:/etc/profile

scp /etc/profile root@DataNode38:/etc/profile

scp -r /opt/hbase root@DataNode35:/opt

scp -r /opt/hbase root@DataNode37:/opt

scp -r /opt/hbase root@DataNode38:/opt

8、在每个节点上

source /etc/profile

9、在主节点启动hbase（只在主节点启动就OK）

start-hbase.sh

10、验证hbase

jps

11、测试hbase shell

hbase shell
Create  ‘test’,’data’
Disable ‘test’
Dorp ‘test’
