所有节点安装ntp

# yum install -y ntp

ntp server端:

# date -s "2018-05-27 23:03:30"

# vi /etc/ntp.conf

在注释下添加两行

#restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

server 127.127.1.0

fudge 127.127.1.0 stratum 11

注释下面

#server 0.centos.pool.ntp.org iburst

#server 1.centos.pool.ntp.org iburst

#server 2.centos.pool.ntp.org iburst

#server 3.centos.pool.ntp.org iburst

# systemctl start ntpd.service

# systemctl enable ntpd.service

ntp客户端(其余四台都为ntp客户端):

# vi /etc/ntp.conf

同样注释下添加两行

#restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

server 192.168.11.131

fudge 127.127.1.0 stratum 11

四行添加注释

#server 0.centos.pool.ntp.org iburst

#server 1.centos.pool.ntp.org iburst

#server 2.centos.pool.ntp.org iburst

#server 3.centos.pool.ntp.org iburst

# systemctl start ntpd.service

所有节点修改主机名(永久)

# hostnamectl set-hostname master1~slave3

临时修改主机名

# hostname master1~slave3

主节点修改hosts文件

# vi /etc/hosts

192.168.11.131 master1

192.168.11.132 master2

192.168.11.133 slave1

192.168.11.134 slave2

192.168.11.135 slave3

把hosts文件覆盖到其他机器

# scp /etc/hosts root@192.168.11.132~135:/etc/

所有节点创建管理用户和组

创建组和用户

# groupadd hduser

# useradd -g hduser hduser

# passwd hduser

创建目录并赋权

每台机器上创建如下文件夹

# mkdir /data1

# mkdir /data2

修改权限

# chown hudser:hduser /data1

# chown hudser:hduser /data2

# su hduser

$ mkdir -p /data1/hadoop_data/hdfs/namenode

$ mkdir -p /data2/hadoop_data/hdfs/namenode

$ mkdir -p /data1/hadoop_data/hdfs/datanode(NameNode不要)

$ mkdir -p /data2/hadoop_data/hdfs/datanode(NameNode不要)

$ mkdir -p /data1/hadoop_data/pids

$ mkdir -p /data2/hadoop_data/pids

$ mkdir -p /data1/hadoop_data/hadoop_tmp

$ mkdir -p /data2/hadoop_data/hadoop_tmp

无密验证

master1和master2节点操作

# su - hduser

$ ssh-keygen -t rsa

$ cd ~/.ssh

$ cat id_rsa.pub >> authorized_keys

master1节点操作

$ ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@master2

master2节点操作

$ scp ~/.ssh/authorized_keys hduser@master1:~/.ssh/

slave1、slave2和slave3节点创建.ssh目录

# mkdir /home/hduser/.ssh

# chown hduser:hduser /home/hduser/.ssh

master1节点操作

$ scp ~/.ssh/authorized_keys hduser@slave1:~/.ssh

$ scp ~/.ssh/authorized_keys hduser@slave2:~/.ssh

$ scp ~/.ssh/authorized_keys hduser@slave3:~/.ssh

master1和master2节点验证

验证方法,分别在两个节点,ssh登陆本机(hdusser用户)及其他四个节点,看看是不是无密登陆。

如果未通过验证,所有机器执行下面命令

$ chmod 600 ~/.ssh/authorized_keys

$ chmod 700 ~/.ssh

所有节点配置java环境

$ mkdir -p /data1/usr/src

上传包到/data1/usr/src目录下

$ cd /data1/usr/src

$ tar xf jdk1.7.0_79.tar -C /data1/usr/

$ vi ~/.bashrc

export JAVA_HOME=/data1/usr/jdk1.7.0_79

export JRE_HOME=$JAVA_HOME/jre

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib/rt.jar

export PATH=$PATH:$JAVA_HOME/bin

$ source ~/.bashrc

mastar1节点配置hadoop(hdsuer用户)

各节点zookeeper配置

http://archive.apache.org/dist/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz

上传包到/data1/usr/src目录下

创建目录

$ mkdir -p /home/hduser/storage/zookeeper

$ cd /data1/usr/src

$ tar -zxf zookeeper-3.4.6.tar.gz -C /data1/usr

$ cp /data1/usr/zookeeper-3.4.6/conf/zoo_sample.cfg /data1/usr/zookeeper-3.4.6/conf/zoo.cfg

server.3=slave1:2888:3888

server.4=slave2:2888:3888

server.5=slave3:2888:3888

master1-slave3各节点依次做操作

$ echo "1" > /home/hduser/storage/zookeeper/myid

$ echo "2" > /home/hduser/storage/zookeeper/myid

$ echo "3" > /home/hduser/storage/zookeeper/myid

$ echo "4" > /home/hduser/storage/zookeeper/myid

$ echo "5" > /home/hduser/storage/zookeeper/myid

$ cd /data1/usr/zookeeper-3.4.6/bin

$ ./zkServer.sh start

slave1、slave2和slave3启动journalnode

$ cd /data1/usr/hadoop-2.7.3/sbin

$ ./sbin/hadoop-daemon.sh start journalnode

用jps确认启动结果

在master1上格式化zookeeper节点格式化(第一次)

$ cd /data1/usr/hadoop-2.7.3

$ ./bin/hdfs zkfc -formatZK

在master1上执行命令:

./bin/hadoop namenode -format

在master1上启动namenode

./sbin/hadoop-daemon.sh start namenode

需要在master2(备节点)上执行数据同步

./bin/hdfs namenode –bootstrapStandby

scp -r /data2/hadoop_data/hdfs/namenode hduser@mster2:/data2/hadoop_data/hdfs/

在master2上启动namenode

./sbin/hadoop-daemon.sh start namenode

设置master1为active

./bin/hdfs haadmin -transitionToActive master1

./bin/hdfs haadmin -getServiceState master1

在master1上启动datanode

./sbin/hadoop-daemons.sh start datanode

启动HDFS(第二次以后)

在master1上执行命令:

./sbin/start-dfs.sh

启动YARN

在master1上执行命令:

./sbin/start-yarn.sh

验证

验证namenode

http://master1:50070

Overview 'master1:9000' (active)

http://master2:50070

Overview 'master2:9000' (standby)

上传文件

./bin/hadoop fs -put /data1/usr/hadoop-2.7.3/etc/hadoop /test

./bin/hadoop fs -ls /test

namenode的备份验证

杀死master1,master2变为active

验证yarn

./bin/hadoop jar /data1/usr/hadoop-2.7.3/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.3.jar wordcount /test/hadoop /test/out

安装HBASE

master1节点操作:

下载hbase-1.2.4-bin.tar.gz,解压

$ cd /data1/usr/src

$ tar -zxvf hbase-1.2.4-bin.tar.gz -C /data1/usr/

$ mkdir -p /data1/hadoop_data/hbase_tmp

$ mkdir -p /data2/hadoop_data/hbase_tmp

配置master1的hbase环境

配置hbase-env.sh

$ vi /data1/usr/hbase-1.2.4/conf/hbase-env.sh

export JAVA_HOME=/data1/usr/jdk1.7.0_79

export HBASE_PID_DIR=/data2/hadoop_data/pids

export HBASE_MANAGES_ZK=false

export HADOOP_HOME=/data1/usr/hadoop-2.7.3

配置hbase-site.xml

$ vi /data1/usr/hbase-1.2.4/conf/hbase-site.xml

  

    hbase.rootdir

    hdfs://masters/hbase

  

  

  

    hbase.cluster.distributed

    true

slave1

slave2

slave3

配置backup-masters

$ vi /data1/usr/hbase-1.2.4/conf/backup-masters

移除 HBase 里面的不必要 log4j 的 jar 包

cd ${HBASE_HOME}/lib

mv slf4j-log4j12-1.7.5.jar slf4j-log4j12-1.7.5.jar.bak

将master1的hbase环境传输到其他节点

$ for ip in `seq 2 5`;do scp -rpq /data1/usr/hbase-1.2.4 192.168.11.13$ip:/data1/usr;done

启动顺序

按hadoop集群的启动步骤,启动hadoop集群

master1上启动Hbase

$ cd /data1/usr/hbase-1.2.4/bin

$ ./start-hbase.sh

验证

$ /data1/usr/hadoop-2.7.3/bin/hadoop fs -ls / 查看hbase是否在HDFS文件系统创建成功

执行: bin/hbase shell 可以进入Hbase管理界面、

输入 status 查看状态

创建表

create 'test', 'cf'

显示表信息

list 'test'

表中插入数据

put 'test', 'row1', 'cf:a', 'value1'

put 'test', 'row2', 'cf:b', 'value2'

put 'test', 'row3', 'cf:c', 'value3'

查询表

scan 'test'

取一行数据

get 'test', 'row1'

失效表

disable 'test'

删除表

drop 'test'

浏览器输入http://master1:16010可以打开Hbase管理界面

http://192.168.11.131/master-status

启动thrift2

hbase-daemons.sh start thrift2

去datanode节点用jps确认
