關于準備工作  我這里就不一一寫出來了，總結一下有主機名，ip，主機名和ip的映射關系，防火墻，ssh免密碼，jdk的安裝及環境變量的設置。

安裝zookeeper到 h5、h6、h7上面

修改 /home/zookeeper-3.4.8/conf的zoo_sample.cfg

cp zoo_sample.cfg 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=/home/zookeeper-3.4.8/data

# the port at which the clients will connect

clientPort=2181

# 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

server.1=h5:2888:3888

server.2=h6:2888:3888

server.3=h7:2888:3888

創建 data文件夾  和在里面  創建文件myid  并寫入數字1

touch data/myid

echo 1 > data/myid

拷貝整個zookeeper到另外兩個節點上

scp -r /home/zookeeper-3.4.8  h6:/home/

scp -r /home/zookeeper-3.4.8  h7:/home/

其他兩個節點的myid  修改為 2  3

安裝hadoop

Slaves：

h5

h6

h7

然后 拷貝到其他節點

scp -r hadoop-2.7.2 h2:/home/    等等

這個地方說明一下  yarn 的HA  是在  h3和h4  上面

啟動順序

###注意：嚴格按照下面的步驟

1.       啟動zookeeper集群

[root@h6 ~]# cd /home/zookeeper-3.4.8/bin/

[root@h6 bin]# ./zkServer.sh start

H5  h6  h7  都一樣

[root@h6 bin]# ./zkServer.sh status

查看狀態

2.       啟動journalnode

[root@h5 bin]# cd /home/hadoop-2.7.2/sbin/

[root@h5 sbin]# ./hadoop-daemons.sh start journalnode

h5: starting journalnode, logging to /home/hadoop-2.7.2/logs/hadoop-root-journalnode-h5.out

h7: starting journalnode, logging to /home/hadoop-2.7.2/logs/hadoop-root-journalnode-h7.out

h6: starting journalnode, logging to /home/hadoop-2.7.2/logs/hadoop-root-journalnode-h6.out

[root@h5 sbin]# jps

2420 JournalNode

2309 QuorumPeerMain

2461 Jps

[root@h5 sbin]# ^C

3.       格式化HDFS

在h1上執行命令:

hdfs namenode -format

格式化后會在根據core-site.xml中的hadoop.tmp.dir配置生成個文件

拷貝tmp 到 h2

[root@h1 hadoop-2.7.2]# scp -r tmp/ h2:/home/hadoop-2.7.2/

4. 格式化ZK(在h1上執行即可)

[root@h1 hadoop-2.7.2]# hdfs zkfc -formatZK

5. 啟動HDFS(在h1上執行)

[root@h1 hadoop-2.7.2]# sbin/start-dfs.sh

16/02/25 05:01:14 WARN hdfs.DFSUtil: Namenode for ns1 remains unresolved for ID null.  Check your hdfs-site.xml file to ensure namenodes are configured properly.

16/02/25 05:01:14 WARN hdfs.DFSUtil: Namenode for ns2 remains unresolved for ID null.  Check your hdfs-site.xml file to ensure namenodes are configured properly.

16/02/25 05:01:14 WARN hdfs.DFSUtil: Namenode for ns3 remains unresolved for ID null.  Check your hdfs-site.xml file to ensure namenodes are configured properly.

Starting namenodes on [h1 h2 masters masters masters]

h5: journalnode running as process 2420. Stop it first.

h6: journalnode running as process 2885. Stop it first.

h7: journalnode running as process 2896. Stop it first.

Starting ZK Failover Controllers on NN hosts [h1 h2 masters masters masters]

masters: ssh: Could not resolve hostname masters: Name or service not known

masters: ssh: Could not resolve hostname masters: Name or service not known

masters: ssh: Could not resolve hostname masters: Name or service not known

h1: starting zkfc, logging to /home/hadoop-2.7.2/logs/hadoop-root-zkfc-h1.out

[root@h1 hadoop-2.7.2]#

6. 啟動YARN(是在h3上執行start-yarn.sh，把namenode和resourcemanager分開是因為性能問題，因為他們都要占用大量資源，所以把他們分開了，他們分開了就要分別在不同的機器上啟動)

[root@h3 sbin]# ./start-yarn.sh

[root@h4 sbin]# ./yarn-daemons.sh start resourcemanager

驗證：

http://192.168.128.11:50070

Overview 'h1:9000' (active)

http://192.168.128.12:50070

Overview 'h2:9000' (standby)

上傳文件

[root@h4 bin]# hadoop fs -put /etc/profile /profile

[root@h4 bin]# hadoop fs -ls

ls: `.': No such file or directory

[root@h4 bin]# hadoop fs -ls /

Found 1 items

-rw-r--r--   3 root supergroup       1814 2016-02-26 19:08 /profile

[root@h4 bin]#

殺死h1

[root@h1 sbin]# jps

2480 NameNode

2868 Jps

2775 DFSZKFailoverController

[root@h1 sbin]# kill -9 2480

[root@h1 sbin]# jps

2880 Jps

2775 DFSZKFailoverController

[root@h1 sbin]# hadoop fs -ls /

Found 1 items

-rw-r--r--   3 root supergroup       1814 2016-02-26 19:08 /profile

此時 h2  變為active

手動啟動 h1的 namenode

[root@h1 sbin]# ./hadoop-daemon.sh start namenode

starting namenode, logging to /home/hadoop-2.7.2/logs/hadoop-root-namenode-h1.out

[root@h1 sbin]# hadoop jar /home/hadoop-2.7.2/s

觀察  h1 狀態為standby

驗證yarn

[root@h1 sbin]# hadoop jar /home/hadoop-2.7.2/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.2.jar wordcount /profile /out

復制到h2  h5,h6,h7上面

整個啟動順序

按照上面啟動hadoop  ha  的順序  先啟動好

然后在h1，h2上啟動hbase

./start-hbase.sh
