# 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

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)
下载hadoop-2.7.3.tar.gz,上传到/data1/usr/src
http://mirrors.cnnic.cn/apache/hadoop/common/hadoop-2.7.3/hadoop-2.7.3.tar.gz
$ cd /data1/usr/src

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
$ vi /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

$ vi /data1/usr/hbase-1.2.4/conf/regionservers
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
