2.关闭集群

stop-yarn.sh

stop-dfs.sh

3.监控集群

hdfs dfsadmin -report

4.单个进程启动/关闭

hadoop-daemon.sh start|stop namenode|datanode| journalnode

yarn-daemon.sh start |stop resourcemanager|nodemanager

五.环境准备

1 .设置ip地址(5台)


[root@sht-sgmhadoopnn-01 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="static"
DNS1="172.16.101.63"
DNS2="172.16.101.64"
GATEWAY="172.16.101.1"
HWADDR="00:50:56:82:50:1E"
IPADDR="172.16.101.55"
NETMASK="255.255.255.0"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="257c075f-6c6a-47ef-a025-e625367cbd9c"

执行命令: service network restart

验证:ifconfig

2 .关闭防火墙(5台)

执行命:service iptables stop

验证:service iptables status

3.关闭防火墙的自动运行(5台)

执行命令:chkconfig iptables off

验证:chkconfig --list | grep iptables

4 设置主机名(5台)

执行命令
(1)hostname sht-sgmhadoopnn-01

(2)vi /etc/sysconfig/network


[root@sht-sgmhadoopnn-01 ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=sht-sgmhadoopnn-01.telenav.cn
GATEWAY=172.16.101.1

5 ip与hostname绑定(5台)

[root@sht-sgmhadoopnn-01 ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.101.55 sht-sgmhadoopnn-01.telenav.cn sht-sgmhadoopnn-01
172.16.101.56 sht-sgmhadoopnn-02.telenav.cn sht-sgmhadoopnn-02
172.16.101.58 sht-sgmhadoopdn-01.telenav.cn sht-sgmhadoopdn-01
172.16.101.59 sht-sgmhadoopdn-02.telenav.cn sht-sgmhadoopdn-02
172.16.101.60 sht-sgmhadoopdn-03.telenav.cn sht-sgmhadoopdn-03

验证:ping sht-sgmhadoopnn-01
6. 设置5台machines,SSH互相通信
http://blog.itpub.net/30089851/viewspace-1992210/

7 .安装JDK(5台)


(1)执行命令
[root@sht-sgmhadoopnn-01 ~]# cd /usr/java
[root@sht-sgmhadoopnn-01 java]# cp /tmp/jdk-7u67-linux-x64.gz ./
[root@sht-sgmhadoopnn-01 java]# tar -xzvf jdk-7u67-linux-x64.gz
(2)vi /etc/profile 增加内容如下:
export JAVA_HOME=/usr/java/jdk1.7.0_67
export HADOOP_HOME=/hadoop/hadoop-2.7.2
export ZOOKEEPER_HOME=/hadoop/zookeeper
export PATH=.:$HADOOP_HOME/bin:$JAVA_HOME/bin:$ZOOKEEPER_HOME/bin:$PATH
#先把HADOOP_HOME, ZOOKEEPER_HOME配置了
#本次实验机器已经配置好了jdk1.7.0_67-cloudera
(3)执行 source /etc/profile
(4)验证:java –version

8.创建文件夹(5台)

mkdir /hadoop

六.安装Zookeeper

sht-sgmhadoopdn-01/02/03

1.下载解压zookeeper-3.4.6.tar.gz


[root@sht-sgmhadoopdn-01 tmp]# wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz
[root@sht-sgmhadoopdn-02 tmp]# wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz
[root@sht-sgmhadoopdn-03 tmp]# wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz
[root@sht-sgmhadoopdn-01 tmp]# tar -xvf zookeeper-3.4.6.tar.gz
[root@sht-sgmhadoopdn-02 tmp]# tar -xvf zookeeper-3.4.6.tar.gz
[root@sht-sgmhadoopdn-03 tmp]# tar -xvf zookeeper-3.4.6.tar.gz
[root@sht-sgmhadoopdn-01 tmp]# mv zookeeper-3.4.6 /hadoop/zookeeper
[root@sht-sgmhadoopdn-02 tmp]# mv zookeeper-3.4.6 /hadoop/zookeeper
[root@sht-sgmhadoopdn-03 tmp]# mv zookeeper-3.4.6 /hadoop/zookeeper

2.修改配置


[root@sht-sgmhadoopdn-01 tmp]# cd /hadoop/zookeeper/conf
[root@sht-sgmhadoopdn-01 conf]# cp zoo_sample.cfg zoo.cfg
[root@sht-sgmhadoopdn-01 conf]# vi zoo.cfg
修改dataDir
dataDir=/hadoop/zookeeper/data
添加下面三行
server.1=sht-sgmhadoopdn-01:2888:3888
server.2=sht-sgmhadoopdn-02:2888:3888
server.3=sht-sgmhadoopdn-03:2888:3888
[root@sht-sgmhadoopdn-01 conf]# cd ../
[root@sht-sgmhadoopdn-01 zookeeper]# mkdir data
[root@sht-sgmhadoopdn-01 zookeeper]# touch data/myid
[root@sht-sgmhadoopdn-01 zookeeper]# echo 1 > data/myid
[root@sht-sgmhadoopdn-01 zookeeper]# more data/myid
1
## sht-sgmhadoopdn-02/03,也修改配置,就如下不同
[root@sht-sgmhadoopdn-02 zookeeper]# echo 2 > data/myid
[root@sht-sgmhadoopdn-03 zookeeper]# echo 3 > data/myid

七.安装Hadoop(HDFS HA+YARN HA)

#step3~7,用SecureCRT ssh 到 linux的环境中,假如copy 内容从window 到 linux 中,中文乱码,请参照修改http://www.cnblogs.com/qi09/archive/2013/02/05/2892922.html

[root@sht-sgmhadoopdn-01 conf]# vi zoo.cfg
修改dataDir
dataDir=/hadoop/zookeeper/data
添加下面三行
server.1=sht-sgmhadoopdn-01:2888:3888
server.2=sht-sgmhadoopdn-02:2888:3888
server.3=sht-sgmhadoopdn-03:2888:3888
[root@sht-sgmhadoopdn-01 conf]# cd ../
[root@sht-sgmhadoopdn-01 zookeeper]# mkdir data
[root@sht-sgmhadoopdn-01 zookeeper]# touch data/myid
[root@sht-sgmhadoopdn-01 zookeeper]# echo 1 > data/myid
[root@sht-sgmhadoopdn-01 zookeeper]# more data/myid
1
## sht-sgmhadoopdn-02/03,也修改配置,就如下不同
[root@sht-sgmhadoopdn-02 zookeeper]# echo 2 > data/myid
[root@sht-sgmhadoopdn-03 zookeeper]# echo 3 > data/myid

8.修改slaves

[root@sht-sgmhadoopnn-01 hadoop]# vi slaves

sht-sgmhadoopdn-01

sht-sgmhadoopdn-02

sht-sgmhadoopdn-03

9.分发文件夹

[root@sht-sgmhadoopnn-01 hadoop]# scp -r hadoop-2.7.2 root@sht-sgmhadoopnn-02:/hadoop

[root@sht-sgmhadoopnn-01 hadoop]# scp -r hadoop-2.7.2 root@sht-sgmhadoopdn-01:/hadoop

[root@sht-sgmhadoopnn-01 hadoop]# scp -r hadoop-2.7.2 root@sht-sgmhadoopdn-02:/hadoop

[root@sht-sgmhadoopnn-01 hadoop]# scp -r hadoop-2.7.2 root@sht-sgmhadoopdn-03:/hadoop

八.启动集群

另外一种启动方式:http://www.micmiu.com/bigdata/hadoop/hadoop2-cluster-ha-setup/

1.启动zookeeper


command: ./zkServer.sh start|stop|status
[root@sht-sgmhadoopdn-01 bin]# ./zkServer.sh start
JMX enabled by default
Using config: /hadoop/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@sht-sgmhadoopdn-01 bin]# jps
2073 QuorumPeerMain
2106 Jps
[root@sht-sgmhadoopdn-02 bin]# ./zkServer.sh start
JMX enabled by default
Using config: /hadoop/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@sht-sgmhadoopdn-02 bin]# jps
2073 QuorumPeerMain
2106 Jps
[root@sht-sgmhadoopdn-03 bin]# ./zkServer.sh start
JMX enabled by default
Using config: /hadoop/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@sht-sgmhadoopdn-03 bin]# jps
2073 QuorumPeerMain
2106 Jps

2.启动hadoop(HDFS+YARN)

a.格式化前,先在journalnode 节点机器上先启动JournalNode进程


[root@sht-sgmhadoopdn-01 ~]# cd /hadoop/hadoop-2.7.2/sbin
[root@sht-sgmhadoopdn-01 sbin]# hadoop-daemon.sh start journalnode
starting journalnode, logging to /hadoop/hadoop-2.7.2/logs/hadoop-root-journalnode-sht-sgmhadoopdn-03.telenav.cn.out
[root@sht-sgmhadoopdn-03 sbin]# jps
16722 JournalNode
16775 Jps
15519 QuorumPeerMain
[root@sht-sgmhadoopdn-02 ~]# cd /hadoop/hadoop-2.7.2/sbin
[root@sht-sgmhadoopdn-02 sbin]# hadoop-daemon.sh start journalnode
starting journalnode, logging to /hadoop/hadoop-2.7.2/logs/hadoop-root-journalnode-sht-sgmhadoopdn-03.telenav.cn.out
[root@sht-sgmhadoopdn-03 sbin]# jps
16722 JournalNode
16775 Jps
15519 QuorumPeerMain
[root@sht-sgmhadoopdn-03 ~]# cd /hadoop/hadoop-2.7.2/sbin
[root@sht-sgmhadoopdn-03 sbin]# hadoop-daemon.sh start journalnode
starting journalnode, logging to /hadoop/hadoop-2.7.2/logs/hadoop-root-journalnode-sht-sgmhadoopdn-03.telenav.cn.out
[root@sht-sgmhadoopdn-03 sbin]# jps
16722 JournalNode
16775 Jps
15519 QuorumPeerMain

b.NameNode格式化


[root@sht-sgmhadoopnn-01 bin]# hadoop namenode -format
16/02/25 14:05:04 INFO namenode.NameNode: STARTUP_MSG:

c.同步NameNode元数据


同步sht-sgmhadoopnn-01 元数据到sht-sgmhadoopnn-02
主要是：dfs.namenode.name.dir，dfs.namenode.edits.dir还应该确保共享存储目录下(dfs.namenode.shared.edits.dir ) 包含NameNode 所有的元数据。
[root@sht-sgmhadoopnn-01 hadoop-2.7.2]# pwd
/hadoop/hadoop-2.7.2
[root@sht-sgmhadoopnn-01 hadoop-2.7.2]# scp -r data/ root@sht-sgmhadoopnn-02:/hadoop/hadoop-2.7.2

d.初始化ZFCK


[root@sht-sgmhadoopnn-01 bin]# hdfs zkfc -formatZK

e.启动HDFS 系统

集群启动,在sht-sgmhadoopnn-01执行start-dfs.sh

集群关闭,在sht-sgmhadoopnn-01执行stop-dfs.sh

#####集群启动############

g.启动YARN运算框架

#####集群启动############

  1. sht-sgmhadoopnn-01启动Yarn，命令所在目录：$HADOOP_HOME/sbin

[root@sht-sgmhadoopnn-01 sbin]# start-yarn.sh
starting yarn daemons
starting resourcemanager, logging to /hadoop/hadoop-2.7.2/logs/yarn-root-resourcemanager-sht-sgmhadoopnn-01.telenav.cn.out
