ZooKeeper安装配置+Hbase安装配置

ZooKeeper安装配置

三台服务器:

192.168.15.5 master

192.168.15.6 node2

192.168.15.7 node2

在每台服务器的host中添加:

192.168.15.5 master

192.168.15.6 node2

192.168.15.7 node2

 

随便在某一台上如:192.168.15.5

解压zookeeper压缩文件:

tar –zxvf zookeeper-3.4.8.tar.gz

配置环境变量:

#zookeeper

export ZOOKEEPER=/usr/tools/zookeeper-3.4.8

export PATH=$PATH:$ZOOKEEPER/bin

使修改生效:

source /etc/profile

到zookeeper的conf目录下面,新增一个zoo.cfg文件

dataDir=/usr/tools/zookeeper-3.4.8/data

添加:

server.1=master:2888:3888

server.2=node1:2888:3888

server.3=node2:2888:3888



 

cd 到安装目录,找到data 目录,新建myid 并填入数字 (1)与server对应

 

 

配置完以后将上述内容全部拷贝到另外两台服务的相同位置

使用scp

scp  -r /usr/tools/zookeeper-3.4.8 root@node1:/usr/tools/

scp  -r /usr/tools/zookeeper-3.4.8 root@node2:/usr/tools/

cd 到安装目录,找到data 目录,修改myid与server对应

/etc/profile环境变了也可以用scp来完成,或者可以各自修改成一致的

三台分别启动zookeeper

zkServer.sh start

每台机器上查看状态:

zkServer.sh status

结果:

ZooKeeper JMX enabled by default

Using config: /usr/tools/zookeeper-3.4.8/bin/../conf/zoo.cfg

Mode: follower

使用jps查看:

jps

结果

QuorumPeerMain

二 HBase安装配置

在某一台上解压hbase的压缩文件,如在192.168.15.5

tar –zxvf hbase-1.2.0-bin.tar.gz

 

配置添加环境变量:

#hbase

export HBASE_HOME=/usr/tools/hbase-1.2.3

exportPATH=$PATH:$HBASE_HOME/bin

 

使环境变量生效

source /etc/profile

 

进入hbase的conf目录,需要修改三个文件:hbase-env.sh、hbase-site.xml和regionservers

其中hbase-env.sh中,在文档的十多行位置处添加:

# The java implementation to use.  Java 1.7+ required.

# export JAVA_HOME=/usr/java/jdk1.6.0/

exportJAVA_HOME=/usr/tools/jdk1.8.0_73

# Extra Java CLASSPATH elements.  Optional.

# export HBASE_CLASSPATH=

然后在后面添加:

# Seconds to sleep between slavecommands.  Unset by default.  This

# can be useful in large clusters, where,e.g., slave rsyncs can

# otherwise arrive faster than the mastercan service them.

# export HBASE_SLAVE_SLEEP=0.1

 

# Tell HBase whether it should manage it'sown instance of Zookeeper or not.

exportHBASE_MANAGES_ZK=false

 

hbase-site.xml中

       

               hbase.zookeeper.quorum

                jokeros1,jokeros2,jokeros3

                Thedirectory shared by RegionServers.

       

       

               hbase.zookeeper.property.dataDir

                /usr/tools/hbase-1.2.0/zookeeperdata

                Propertyfrom ZooKeeper config zoo.cfg.

                The directory where thesnapshot is stored.

               

       

       

                hbase.tmp.dir

                /usr/tools/hbase-1.2.0/tmpdata

       

       

               hbase.rootdir

                hdfs://jokeros1:9000/hbase

                Thedirectory shared by RegionServers.

       

       

               hbase.cluster.distributed

                true

                The mode thecluster will be in. Possible values are

                false: standalone andpseudo-distributed setups with managed Zookeeper

                true: fully-distributed withunmanaged Zookeeper Quorum (see hbase-env.sh)

               

       

regionservers文件中添加各个从属服务器的ip或者hostname:

 

master

node1

node2

 

保存后分别把hbase的整个文件夹拷贝到其他服务器:

 

scp -r /usr/tools/hbase-1.2.3 root@node1:/usr/tools/

scp –r  /usr/tools/hbase-1.2.3 root@node2:/usr/tools/

 

在hadoop的namenode节点上启动hbase服务

start-hbase.sh

 

启动后:jps

HRegionServer

HMaster

子节点

HRegionServer

 

启动顺序

Hadoop-hdfs-------》hadoop-yarn------》zookeeper------》hbase
