hbase0.95.2部署

下载安装包

hbase-0.95.2-cdh5.0.0-beta-1.tar.gz

hbase需对应hadoop版本

解压

tar zxvf hbase-0.95.2-cdh5.0.0-beta-1.tar.gz

ln -s /opt/hbase-0.95.2-cdh5.0.0-beta-1 ~/hbase

所有节点都解压

ssh双向认证

配置所有机器hosts

vi /etc/hosts

10.10.1.1 hadoop1

10.10.1.2 hadoop2

10.10.1.3 hadoop3

使用hostname 设置主机名

在.ssh目录生成id_rsa.pub ，添加到本机~/.ssh/authorized_keys文件里面

ssh-keygen -q -t rsa

cat ~/.ssh/id_rsa.pub >>~/.ssh/authorized_keys

本机登入验证：ssh localhost

复制authorized_keys到其他机器上

scp ~/.ssh/id_rsa.pub hadoop3:~/

cat ~/id_rsa.pub >> ~/.ssh/authorized_keys 

chmod 600 ~/.ssh/authorized_keys

chmod 700 ~/.ssh

其他机器重复以上步骤

修改环境参数

vi /etc/profile

增加以下内容：

export JAVA_HOME=/opt/jdk1.7.0_51

export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:/lib/dt.jar

export PATH=$PATH:$JAVA_HOME/bin

export HADOOP_DEV_HOME=/home/hadoop/hadoop

export PATH=$PATH:$HADOOP_DEV_HOME/bin

修改ulimit

vi /etc/security/limits.d/90-nproc.conf 

* soft nproc 502400

执行环境参数 

source /etc/profile

修改hadoop配置

1.编辑同步脚本:vi hbase/cp2slaves.sh

BASE_PATH=`dirname $0`

cd $BASE_PATH

echo `/bin/pwd`

scp conf/* hadoop2:~/hbase/conf/

scp conf/* hadoop3:~/hbase/conf/

2.配置hbase/conf/hbase-env.sh 

export JAVA_HOME=/opt/jdk1.7.0_51

export HBASE_PID_DIR=${HBASE_LOG_DIR}

export HBASE_MANAGES_ZK=true

3.配置hbase/conf/hbase-site.xml 

<property>

<name>hbase.rootdir</name>

<value>hdfs://hadoop1:9000/hbase</value>

</property>

<property>

<name>hbase.cluster.distributed</name>

<value>true</value>

</property>

<property>

<name>hbase.zookeeper.quorum</name>

<value>hadoop1</value>

</property>

<property>

<name>zookeeper.session.timeout</name>

<value>60000</value>

</property>

<property>

<name>hbase.zookeeper.property.clientPort</name>

<value>2181</value>

</property>

<property>

<name>hbase.tmp.dir</name>

<value>/home/hadoop/hbase/tmp</value>

<description>Temporary directory on the local filesystem.</description>

</property>

<property>

<name>hbase.client.keyvalue.maxsize</name>

<value>10485760</value>

</property>

4.配置hbase/conf/regionservers 

hadoop1

hadoop2

hadoop3

5.同步配置文件

sh hadoop/cp2slaves.sh

启动

hbase/bin/start-hbase.sh 

测试验证

http://hadoop1:60010

hbase/bin/hbase shell

停止

hbase/bin/stop-hbase.sh
