Hbase

1.同步时间

yum -y install chrony
vi /etc/chrony.conf
pool time1.aliyun.com iburst
保存
systemctl enable --now chronyd
systemctl status chronyd

2.安装hbase

tar xf /opt/software/hbase-1.2.1-bin.tar.gz -C /usr/local/src/
cd /usr/local/src/
mv hbase-1.2.1 hbase
vi /etc/profile.d/hbase.sh
export HBASE_HOME=/usr/local/src/hbase
export PATH=${HBASE_HOME}/bin:$PATH

保存以上配置后执行以下命令

source /etc/profile.d/hbase.sh
echo $PATH

3.在master上配置hbase

配置环境变量
cd /usr/local/src/hbase/conf/
vi hbase-env.sh
export JAVA_HOME=/usr/local/src/jdk
export HBASE_MANAGES_ZK=true
export HBASE_CLASSPATH=/usr/local/src/hadoop/etc/hadoop/

写配置文件
vi hbase-site.xml

<configuration>
<property>
        <name>hbase.rootdir</name>
        <value>hdfs://master:9000/hbase</value>
</property>
<property>
        <name>hbase.master.info.port</name>
        <value>60010</value>
</property>
<property>
        <name>hbase.zookeeper.property.clientPort</name>
        <value>2181</value>
</property>
<property>
        <name>zookeeper.session.timeout</name>
        <value>10000</value>
</property>
<property>
        <name>hbase.zookeeper.quorum</name>
        <value>master,slave1,slave2</value>
</property>
<property>
        <name>hbase.tmp.dir</name>
        <value>/usr/local/src/hbase/tmp</value>
</property>
<property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
</property>
</configuration>

创建文件夹
mkdir -p /usr/local/src/hbase/tmp
vi regionservers
192.168.3.139
192.168.3.140

4.同步配置文件至每个节点

scp -r /usr/local/src/hbase slave1:/usr/local/src/
scp -r /usr/local/src/hbase slave2:/usr/local/src/
scp /etc/profile.d/hbase.sh slave1:/etc/profile.d/
scp /etc/profile.d/hbase.sh slave2:/etc/profile.d/
并修改文件权限
chown -R hadoop.hadoop /usr/local/src
ssh slave1 'chown -R hadoop.hadoop /usr/local/src'
ssh slave2 'chown -R hadoop.hadoop /usr/local/src'
ll /usr/local/src/
su - hadoop

hadoop之间得
做相互免密登录
