实战hadoop2.6.3+zookeeper3.4.6+hbase1.0.2高可用集群方案

实战hadoop2.6.3+zookeeper3.4.6+hbase1.0.2高可用集群方案

一、安装前准备

1.环境5台

2、修改hosts文件

[root@hadoop01 ~]# cat /etc/hosts

192.168.10.201hadoop01

192.168.10.202hadoop02

192.168.10.203hadoop03

192.168.10.204hadoop04

192.168.10.205hadoop05

3、ssh 免密码登录

在每台操作

[root@hadoop01 ~]# mkidr ~/.ssh

[root@hadoop01 ~]# chmod 700 ~/.ssh

[root@hadoop01 ~]#cd ~/.ssh/

[root@hadoop01 .ssh ]ssh-keygen -t rsa

五台操作完成 后做成公钥文件

[root@hadoop01 .ssh ] ssh hadoop02 cat /root/.ssh/id_rsa.pub >> authorized_keys

[root@hadoop01 .ssh ] ssh hadoop03 cat /root/.ssh/id_rsa.pub >> authorized_keys

[root@hadoop01 .ssh ] ssh hadoop04 cat /root/.ssh/id_rsa.pub >> authorized_keys

[root@hadoop01 .ssh ] ssh hadoop05 cat /root/.ssh/id_rsa.pub >> authorized_keys

[root@hadoop01 .ssh ] ssh hadoop01 cat /root/.ssh/id_rsa.pub >> authorized_keys

[root@hadoop01 .ssh]# chmod 600 authorized_keys

[root@hadoop01 .ssh]# scp authorized_keys hadoop02:/root/.ssh/

[root@hadoop01 .ssh]# scp authorized_keys hadoop03:/root/.ssh/

[root@hadoop01 .ssh]# scp authorized_keys hadoop04:/root/.ssh/

[root@hadoop01 .ssh]# scp authorized_keys hadoop05:/root/.ssh/

测试ssh信任

[root@hadoop01 .ssh]# ssh hadoop02 date

Mon Aug  8 11:07:23 CST 2016

[root@hadoop01 .ssh]# ssh hadoop03 date

Mon Aug  8 11:07:26 CST 2016

[root@hadoop01 .ssh]# ssh hadoop04 date

Mon Aug  8 11:07:29 CST 2016

[root@hadoop01 .ssh]# ssh hadoop05 date

5.服务时间同步(五台操作)

yum -y install ntpdate

[root@hadoop01 .ssh]# crontab -l

0 * * * * /usr/sbin/ntpdate 0.rhel.pool.ntp.org && /sbin/clock -w

可以采用别的方案同步时间

6.修改文件打开数（五台操作）

[root@hadoop01 ~]# vi /etc/security/limits.conf

root soft nofile 65535

root hard nofile 65535

root soft nproc 32000

root hard nproc 32000

[root@hadoop01 ~]# vi /etc/pam.d/login

session  required        pam_limits.so

修改完后重启系统

二、安装hadoop+zookeeper HA

1.安装jdk  (五台操作)

解压jdk

[root@hadoop01 ~] cd /opt

[root@hadoop01 opt]# tar zxvf jdk-7u21-linux-x64.tar.gz

[root@hadoop01 opt]# mv jdk1.7.0_21 jdk

配置到环境变量/etc/profile

[root@hadoop01 opt]# vi /etc/profile

#java

JAVA_HOME=/opt/jdk

PATH=$JAVA_HOME/bin:$PATH

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

export JAVA_HOME

export PATH

export CLASSPATH

配置文件生效

[root@hadoop01 opt]# source /etc/profile 

[root@hadoop01 opt]# java -version

java version "1.7.0_21"

Java(TM) SE Runtime Environment (build 1.7.0_21-b11)

Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

以上说明生效

2.解压hadoop并修改环境变量

[root@hadoop01 ~]# tar zxvf hadoop-2.6.3.tar.gz

[root@hadoop01 ~]#mkdir /data

[root@hadoop01 ~]# mv hadoop-2.6.3 /data/hadoop

[root@hadoop01 data]# vi /etc/profile

##hadoop

export HADOOP_HOME=/data/hadoop

export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/bin

[root@hadoop01 data]# source /etc/profile

3.修改hadoop配置文件

[root@hadoop01 data]# cd /data/hadoop/etc/hadoop/

[root@hadoop01 hadoop]# vi slaves

hadoop01

hadoop02

hadoop03

hadoop04

hadoop05

以上利用hadoop01,hadoop02两台磁盘空间，也增加进去了，不介意增加。

[root@hadoop01 hadoop]# vi hadoop-env.sh

[root@hadoop01 hadoop]# vi yarn-env.sh

修改core-site.xml文件

[root@hadoop01 hadoop]# vi core-site.xml

         </queue>

</allocations>

创建相关xml配置中目录

mkdir -p /data/hadoop/mydata/yarn

4.解压zookeeper并修改环境变量

[root@hadoop01 ~]# tar zxvf zookeeper-3.4.6.tar.gz

[root@hadoop01 ~]#mv zookeeper-3.4.6 /data/zookeeper

[root@hadoop01 ~]# vi /etc/profile

##zookeeper

export ZOOKEEPER_HOME=/data/zookeeper

export PATH=$PATH:$ZOOKEEPER_HOME/bin:$ZOOKEEPER_HOME/conf

[root@hadoop01 ~]# source /etc/profile

5.修改zookeeper配置文件

[root@hadoop01 ~]# cd /data/zookeeper/conf/

[root@hadoop01 conf]# cp zoo_sample.cfg zoo.cfg

[root@hadoop01 conf]# vi zoo.cfg

# The number of milliseconds of each tick

tickTime=2000

# The number of ticks that the initial

# synchronization phase can take

initLimit=10

# The number of ticks that can pass between

# sending a request and getting an acknowledgement

syncLimit=5

# the directory where the snapshot is stored.

# do not use /tmp for storage, /tmp here is just

# example sakes.

dataDir=/data/hadoop/mydata/zookeeper

dataLogDir=/data/hadoop/mydata/zookeeperlog

# the port at which the clients will connect

clientPort=2190

server.1=hadoop01:2888:3888

server.2=hadoop02:2888:3888

server.3=hadoop03:2888:3888

server.4=hadoop04:2888:3888

server.5=hadoop05:2888:3888

# the maximum number of client connections.

# increase this if you need to handle more clients

#maxClientCnxns=60

#

# Be sure to read the maintenance section of the

# administrator guide before turning on autopurge.

#

# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

#

# The number of snapshots to retain in dataDir

#autopurge.snapRetainCount=3

# Purge task interval in hours

# Set to "0" to disable auto purge feature

#autopurge.purgeInterval=1

创建目录

mkdir /data/hadoop/mydata/zookeeper

mkdir /data/hadoop/mydata/zookeeperlog

6.把配置hadoop、zookeeper文件目录到其他四台中

[root@hadoop01 ~]# scp -r /data/hadoop hadoop02:/data/

[root@hadoop01 ~]# scp -r /data/hadoop hadoop03:/data/

[root@hadoop01 ~]# scp -r /data/hadoop hadoop04:/data/

[root@hadoop01 ~]# scp -r /data/hadoop hadoop05:/data/

[root@hadoop01 ~]# scp -r /data/zookeeper hadoop02:/data/

[root@hadoop01 ~]# scp -r /data/zookeeper hadoop03:/data/

[root@hadoop01 ~]# scp -r /data/zookeeper hadoop04:/data/

[root@hadoop01 ~]# scp -r /data/zookeeper hadoop05:/data/

在hadoop02修改yarn-site.xml

[root@hadoop02 hadoop]# cd /data/hadoop/etc/hadoop/

把rm1修改成rm2

[root@hadoop02 hadoop]# vi yarn-site.xml

<name>yarn.resourcemanager.ha.id</name>

<value>rm2</value>

[root@hadoop01 ~]# vi /data/hadoop/mydata/zookeeper/myid

1

[root@hadoop02 ~]# vi /data/hadoop/mydata/zookeeper/myid

2

[root@hadoop03 ~]# vi /data/hadoop/mydata/zookeeper/myid

3

[root@hadoop04 ~]# vi /data/hadoop/mydata/zookeeper/myid

4

[root@hadoop05 ~]# vi /data/hadoop/mydata/zookeeper/myid

5

7、启动zookeeper

五台操作zkServer.sh start

[root@hadoop01 ~]# zkServer.sh start

 [root@hadoop01 ~]# zkServer.sh status

ZooKeeper JMX enabled by default

Using config: /data/zookeeper/bin/../conf/zoo.cfg

Mode: follower

[root@hadoop03 ~]# zkServer.sh status

ZooKeeper JMX enabled by default

Using config: /data/zookeeper/bin/../conf/zoo.cfg

Mode: leader

You have new mail in /var/spool/mail/root

正常情况只有一台leader状态

8、格式化zookeeper集群

在hadoop机器执行命令

[root@hadoop01 ~]# hdfs zkfc -formatZK

9.启动journalnode进程

在每台启动（五台）

[root@hadoop01 ~]# cd /data/hadoop/sbin/

[root@hadoop01 sbin]# ./hadoop-daemon.sh start journalnode

10.格式化namenode

在hadoop01上执行命令

[root@hadoop01 ~]# hdfs namenode -format

11.启动namenode

在hadoop01执行命令

[root@hadoop01 ~]# cd /data/hadoop/sbin/

[root@hadoop01 sbin]# ./hadoop-daemon.sh start  namenode

12.将刚才格式化的namenode信息同步么备用namenode上

[root@hadoop01 ~]# hdfs namenode -bootstrapStandby

13.在hadoop02上启动namenode

[root@hadoop02 ~]# cd /data/hadoop/sbin/

[root@hadoop02  sbin]# ./hadoop-daemon.sh start  namenode

14.启动所有datanode

在每台执行这是根据slaves来的

[root@hadoop01 ~]# cd /data/hadoop/sbin/

[root@hadoop01 sbin]# ./hadoop-daemon.sh start  datanode

15.启动yarn

在hadoop01上执行命令

root@hadoop01 ~]# cd /data/hadoop/sbin/

[root@hadoop01 sbin]# ./start-yarn.sh

16.启动ZKFC

在hadoop01和hadoop02上启动

[root@hadoop01 ~]# cd /data/hadoop/sbin/

[root@hadoop01 sbin]# ./hadoop-daemon.sh start zkfc

17.启动成功结果

三、安装hbase HA

1.解压hbase修改配置文件

[root@hadoop01 ~]# tar zxvf hbase-1.0.2-bin.tar.gz

[root@hadoop01 ~]# mv hbase-1.0.2 /data/hbase

配置环境变量

[root@hadoop01 ~]# vi /etc/profile

##hbase

export HBASE_HOME=/data/hbase

export PATH=$PATH:$HBASE_HOME/bin

[root@hadoop01 ~]# source /etc/profile

[root@hadoop01 ~]# cd /data/hbase/conf/

[root@hadoop01 conf]# vi hbase-env.sh

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

export JAVA_HOME="/opt/jdk"

# Extra Java CLASSPATH elements.  Optional.

#记得以下一定要配置,HMaster会启动不了

export HBASE_CLASSPATH=/data/hadoop/etc/hadoop

# Where log files are stored.  $HBASE_HOME/logs by default.

export HBASE_LOG_DIR=/data/hbase/logs

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

export HBASE_MANAGES_ZK=false

修改hbase-site.xml

[root@hadoop01 conf]# vi hbase-site.xml

<?xml version="1.0"?>

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

[root@hadoop01 conf]# vi regionservers

hadoop01

hadoop02

hadoop03

hadoop04

hadoop05

~             

创建文件目录

mkdir /data/hbase/tmp

增加backup-master

 [root@hadoop01 conf]# vi backup-masters

hadoop02

以上都配置完成

2、把文件传到其他服务器上

[root@hadoop01 conf]# scp -r /data/hbase hadoop02:/data/

[root@hadoop01 conf]# scp -r /data/hbase hadoop03:/data/

[root@hadoop01 conf]# scp -r /data/hbase hadoop04:/data/

[root@hadoop01 conf]# scp -r /data/hbase hadoop05:/data/

3.启动hbase

在hadoop01执行命令

[root@hadoop01 conf]# start-hbase.sh

4.启动结果

可以通过jps查看

[root@hadoop01 conf]# jps

2540 NodeManager

1686 QuorumPeerMain

2134 JournalNode

2342 DFSZKFailoverController

3041 HMaster

1933 DataNode

3189 HRegionServer

2438 ResourceManager

7848 Jps

1827 NameNode

以后启动过程

每台执行（五台）

[root@hadoop01 ~]# zkServer.sh start

在hadoop01启动

[root@hadoop01 ~]# cd /data/hadoop/sbin/

[root@hadoop01 sbin]# ./start-dfs.sh

[root@hadoop01 sbin]# ./start-yarn.sh

最后启动hbase

[root@hadoop01 sbin]# start-hbase.sh

关闭过程

先关闭hbase

stop-hbase.sh

在hadoop01关闭

[root@hadoop01 ~]# cd /data/hadoop/sbin/

[root@hadoop01 sbin]# ./stop-yarn.sh

[root@hadoop01 sbin]# ./stop-dfs.sh
