一、主机分布
节点功能
主机 | ZK | JN | zkfc | NN | DN | RM | NM | HM | HR | kdc |
Test1 | * | * | * | * | * | * | * | * | * | |
Test2 | * | * | * | * | * | * | * | * | * | |
Test3 | * | * | * | * | * |
Host
所有节点:
127.0.0.1 localhost
192.168.3.11 test1
192.168.3.12 test2
192.168.3.13 test3
创建ssh信任关系
主节点要信任自己和其它节点,即ssh连接不用密码。
主机test1:
# ssh-keygen (一路回车)
# ssh-copy-id test1
Are you sure you want to continueconnecting (yes/no)? yes
root@test1's password:
# ssh-copy-id test2
# ssh-copy-id test3
主机test2:
# ssh-keygen (一路回车)
# ssh-copy-id test2
Are you sure you want to continueconnecting (yes/no)? yes
root@test2's password:
# ssh-copy-id test1
# ssh-copy-id test3
二、Zookeeper下载
http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz
解压
# tar zxf zookeeper-3.4.6.tar.gz -C/usr/local/
修改配置文件
# cd /usr/local/zookeeper-3.4.6/conf
# cp zoo_sample.cfg zoo.cfg
# vim zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/zookeeper
clientPort=2181
maxClientCnxns=600
server.1=test1:2888:3888
server.2=test2:2888:3888
server.3=test3:2888:3888
zookeeper日志设定
改日志输出位置到/var/log/zookeeper/zookeeper.log,输出和清除方式
# mkdir /var/log/zookeeper
# vim/usr/local/zookeeper-3.4.6/conf/log4j.properties
zookeeper.root.logger=INFO,ROLLINGFILE
zookeeper.log.dir=/var/log/zookeeper
# vim/usr/local/zookeeper-3.4.6/bin/zkEnv.sh
if [ "x${ZOO_LOG_DIR}" ="x" ]
then
ZOO_LOG_DIR="/var/log/zookeeper"
fi
if [ "x${ZOO_LOG4J_PROP}" ="x" ]
then
ZOO_LOG4J_PROP="INFO,ROLLINGFILE"
Fi
同步配置
主机test1:
# scp -r /usr/local/zookeeper-3.4.6/ test2:/usr/local/
# scp -r /usr/local/zookeeper-3.4.6/ test3:/usr/local/
创建myid文件
主机test1:
# echo '1' >>/var/zookeeper/myid
主机test2:
# echo '2' >>/var/zookeeper/myid
主机test3:
# echo '3' >>/var/zookeeper/myid
操作命令
启动:
# /usr/local/zookeeper-3.4.6/bin/zkServer.shstart
加入开机启动:
# echo '/usr/local/zookeeper-3.4.6/bin/zkServer.shstart' >> /etc/rc.local
查看状态:
# /usr/local/zookeeper-3.4.6/bin/zkServer.shstatus
客户端:
# /usr/local/zookeeper-3.4.6/bin/zkCli.sh
三、Hadoop1、安装
下载
解压
主机test1:
# tar zxf hadoop-2.4.0_x64.tar.gz -C /usr/local/
环境变量
所有节点:
# vim /etc/profile.d/hadoop.sh
export HADOOP_HOME=/usr/local/hadoop-2.4.0/
exportPATH=$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH
exportHADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop/
exportHADOOP_COMMON_LIB_NATIVE_DIR=${HADOOP_HOME}/lib/native
exportHADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib/native"
exportLD_LIBRARY_PATH=$HADOOP_HOME/lib/native
export HADOOP_PID_DIR=/hadoop/pid
export HADOOP_LOG_DIR=/var/log/hadoop
export YARN_PID_DIR=/hadoop/pid
export YARN_LOG_DIR=/var/log/Hadoop
exportHADOOP_MAPRED_LOG_DIR=/var/log/hadoop
export HADOOP_MAPRED_PID_DIR=/hadoop/pid
# source /etc/profile
创建haoop所需目录
所有节点:
# mkdir /Hadoop
# mkdir /var/log/hadoop/

配置文件slaves
# vim/usr/local/hadoop-2.4.0/etc/hadoop/slaves
test1
test2
test3
同步配置到其它主机
主机test1:
# scp -r /usr/local/hadoop-2.4.0/ test2:/usr/local/
# scp -r /usr/local/hadoop-2.4.0/ test3:/usr/local/
3、启动
格式化ZooKeeper集群
主机test1:
# hdfs zkfc –formatZK
# /usr/local/zookeeper-3.4.6/bin/zkCli.sh
[zk: localhost:2181(CONNECTED) 1] ls /hadoop-ha
[cluster1]
启动JournalNode集群
所有主节点(test1,test2)都启动:
# hadoop-daemon.sh start journalnode
格式化namenode
主机test1:
# hdfs namenode -format -clusterId c1
启动第一个namenode
主机test1:
# hadoop-daemon.sh start namenode
第二个namenode同步元数据
主机test2:
# hdfs namenode –bootstrapStandby
启动第二个namenode
主机test2:
# hadoop-daemon.sh start namenode
启动ZooKeeperFailoverController
所有主节点都启动:
使namenode一个是active另一个是standby
# hadoop-daemon.sh start zkfc
启动所有datanode
所有从节点(test1,test2,test3)都启动:
# hadoop-daemon.sh start datanode
验证hdfs
# hadoop fs -put xx.txt /
# hdfs dfs -ls /
启动mapreduce
主机test1:
# start-yarn.sh
包括了resourcemanager和所有nodemanager
启动另一个resource-manager
主机test2:
# yarn-daemon.sh start resourcemanager
验证mapreduce
# hadoop jar/usr/local/hadoop-2.4.0/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.4.0.jar wordcount /xx.txt /out
# hdfs dfs -text /out/part-r-00000
四、Hbase1、安装
下载hbase并解压
http://mirrors.cnnic.cn/apache/hbase/hbase-0.98.1/hbase-0.98.1-hadoop2-bin.tar.gz
# tar zxf hbase-0.98.1-hadoop2-bin.tar.gz–C /usr/local/
环境变量
所有节点:
# vim /etc/profile.d/hbase.sh
export HBASE_HOME=/usr/local/hbase-0.98.1
export HBASE_CONF_DIR=$HBASE_HOME/conf
export PATH=$HBASE_HOME/bin:$PATH
export HBASE_CLASSPATH=$HADOOP_HOME/etc/Hadoop
export HBASE_LOG_DIR=/var/log/hbase
export HBASE_PID_DIR=/Hadoop/pid
export HBASE_MANAGES_ZK=false
# source /etc/profile
创建日志目录
所有节点:
# mkdir -p /var/log/hbase
更换haoop2.4的jar包
主机test1:创建一个脚本
# vim lib.sh
#!/bin/sh
hbase_dir=/usr/local/hbase-0.98.1/
hadoop_dir=/usr//local/hadoop-2.4.0/
cd ${hbase_dir}/lib/
find . -name "hadoop*jar" | sed's/2.2.0/2.4.0/g' | sed 's/.\///g' > f.log
rm ./hadoop*jar
cat ./f.log | while read Line
do
find ${hadoop_dir}/share/hadoop -name"$Line" | xargs -i cp {} ./
done
rm ./f.log
# sh lib.sh
# ll /usr/local/hbase-0.98.1/lib/hadoop*jar
2、配置
配置文件hbase-site.xml
所有配置文件先在test1配置,然后同步到其它主机。
主机test1:
<property>
<name>hbase.rootdir</name>
<value>hdfs://cluster1/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>test1:2181,test2:2181,test3:2181</value>
</property>
配置文件backup-master
# vim/usr/local/hbase-0.98.1/conf/backup-masters

test3
复制配置到其它节点
主机test1:
# scp -r /usr/local/hbase-0.98.1/ test2:/usr/local/
# scp -r /usr/local/hbase-0.98.1/ test3:/usr/local/
3、启动
启动hbase集群
主机test1:
# start-hbase.sh
验证
# jps
2995 HMaster(主节点)
3140 HRegionServer (从节点)
