zookeeper和hbase安装
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
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'
