1.主机规划

主机 内网IP安装软件 运行进程
master1192.168.214.111jdk、hadoop、zookeeperNameNode、ResourceManager、DFSZKFailoverController(zkfc)、QuorumPeerMain
master2192.168.214.112jdk、hadoop、zookeeperNameNode、ResourceManager、DFSZKFailoverController(zkfc)、QuorumPeerMain
slave1192.168.214.113jdk、hadoop、zookeeperDataNode、NodeManager、JournalNode、QuorumPeerMain
slave2192.168.214.114jdk、hadoop、zookeeperDataNode、NodeManager、JournalNode、QuorumPeerMain
slave3192.168.214.115jdk、hadoop、zookeeperDataNode、NodeManager、JournalNode、QuorumPeerMain

注意：针对HA模式，就不需要SecondaryNameNode了，因为STANDBY状态的namenode会负责做checkpoint

2.Linux添加hosts信息，保证每台都可以相互ping通

[root@master1 /usr/local 13:05:26]$cat /etc/hosts
192.168.214.111 master1
192.168.214.112 master2
192.168.214.113 slave1
192.168.214.114 slave2
192.168.214.115 slave3
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

预先配置所有环境变量

# Zookeeper
export ZOOKEEPER_HOME=/usr/local/zookeeper
export PATH=$PATH:$ZOOKEEPER_HOME/bin
# JDK
export JAVA_HOME=/usr/local/jdk1.8.0_152
export PATH=$PATH:$JAVA_HOME/bin
# Hadoop
export HADOOP_HOME=/usr/local/hadoop
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin

3 Zookeeper部署

3.1 配置信息

zoo.cfg

#单个客户端与单台服务器之间的连接数的限制，是ip级别的，默认是60，如果设置为0，那么表明不作任何限制。
maxClientCnxns=1500
# 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=/usr/local/zookeeper/data
# the port at which the clients will connect
clientPort=2181
# leader和follow通信端口和投票选举端口
server.1=master1:2888:3888
server.2=master2:2888:3888
server.3=slave1:2888:3888
server.4=slave2:2888:3888
server.5=slave3:2888:3888

3.2 添加myid文件

mkdir /usr/local/zookeeper/data
echo 1 > /usr/local/zookeeper/data/myid
#依次配置 master1\master2\slave1\slave2\slave3 ID递增

3.3 启动zk服务

# 依次启动zk服务  
[root@master1 /usr/local 13:05:26]$zkServer.sh start  
JMX enabled by default  
Using config: /app/zookeeper/bin/../conf/zoo.cfg  
Starting zookeeper ... STARTED

3.4 查询运行状态

[root@master1 /usr/local 13:06:58]$./sync.sh 'zkServer.sh status'
[zkServer.sh status]
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: leader
Connection to master2 closed.
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: follower
Connection to slave1 closed.
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: follower
Connection to slave2 closed.
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: follower
Connection to slave3 closed.

PS：4个follower 1个leader

4 Hadoop部署与配置修改

slaves

slave1
slave2
slave3

PS：改后配置后，将这些配置拷到其他Hadoop机器

4.2 启动相关服务

注意：第一次启动时严格按照下面的步骤！！！！！！！

# 根据规划在slave1、slave2、slave3启动 journalnode
# 在第一次格式化的时候需要先启动 journalnode 后就不必了
[root@slave1 ~ 13:25:32]$hadoop-daemon.sh start journalnode
starting journalnode, logging to /usr/local/hadoop/logs/hadoop-root-journalnode-slave1.out
[root@slave1 ~ 13:25:42]$jps
13234 Jps
13175 JournalNode
12238 QuorumPeerMain

4.3 格式化HDFS

4.4 拷贝数据文件

方法1

格式化后会在根据core-site.xml中的hadoop.tmp.dir配置生成文件，这里我配置的是/usr/local/hadoop/tmp，然后将目录下所有文件拷贝到master2的同目录下

[root@master1 /usr/local 13:02:09]$scp -r /usr/local/hadoop/tmp/* root@master2:/usr/local/hadoop/tmp/
VERSION                                                 100%  207   179.2KB/s   00:00

fsimage_0000000000000000000.md5                         100%   62    50.2KB/s   00:00

方法2

hdfs namenode -bootstrapStandby # 不过需要master2的Hadoop起来才行

4.5 格式化ZKFC

4.6 启动HDFS

在master1上执行

[root@master1 /usr/local 13:25:10]$start-dfs.sh 
Starting namenodes on [master1 master2]
master2: starting namenode, logging to /usr/local/hadoop/logs/hadoop-root-namenode-master2.out
master1: starting namenode, logging to /usr/local/hadoop/logs/hadoop-root-namenode-master1.out
slave3: starting datanode, logging to /usr/local/hadoop/logs/hadoop-root-datanode-slave3.out
slave2: starting datanode, logging to /usr/local/hadoop/logs/hadoop-root-datanode-slave2.out
slave1: starting datanode, logging to /usr/local/hadoop/logs/hadoop-root-datanode-slave1.out
Starting journal nodes [slave1 slave2 slave3]
slave3: starting journalnode, logging to /usr/local/hadoop/logs/hadoop-root-journalnode-slave3.out
slave1: journalnode running as process 13175. Stop it first.
slave2: starting journalnode, logging to /usr/local/hadoop/logs/hadoop-root-journalnode-slave2.out
Starting ZK Failover Controllers on NN hosts [master1 master2]
master2: starting zkfc, logging to /usr/local/hadoop/logs/hadoop-root-zkfc-master2.out
master1: starting zkfc, logging to /usr/local/hadoop/logs/hadoop-root-zkfc-master1.out

4.7 启动YARN

在master1启动yarn

[root@master1 /usr/local 13:39:31]$start-yarn.sh
starting yarn daemons
starting resourcemanager, logging to /usr/local/hadoop/logs/yarn-root-resourcemanager-master1.out
slave1: starting nodemanager, logging to /usr/local/hadoop/logs/yarn-root-nodemanager-slave1.out
slave2: starting nodemanager, logging to /usr/local/hadoop/logs/yarn-root-nodemanager-slave2.out
slave3: starting nodemanager, logging to /usr/local/hadoop/logs/yarn-root-nodemanager-slave3.out

在master2启动 resourcemanager

[root@master2 ~ 13:41:50]$yarn-daemon.sh start resourcemanager
starting resourcemanager, logging to /usr/local/hadoop/logs/yarn-root-resourcemanager-master2.out

4.8 启动说明

第一次启动的时候请严格按照上面的步骤【第一次涉及格式化问题】

第二次以及之后，步骤为： 启动zookeeper、HDFS、YARN

5. 浏览访问

5.1 Hdfs访问

http://master1:50070

http://master2:50070

5.2 master1挂了Active自动切换

# kill掉master1的namenode
[root@master1 /usr/local 13:46:59]$jps
15635 Jps
2548 QuorumPeerMain
15095 ResourceManager
14651 NameNode
14988 DFSZKFailoverController
[root@master1 /usr/local 13:52:20]$kill 14651
[root@master1 /usr/local 13:52:28]$jps
2548 QuorumPeerMain
15669 Jps
15095 ResourceManager
14988 DFSZKFailoverController
[root@master1 /usr/local 13:52:32]$

Namenode挂了所以master1不能访问

http://master2:50070

可见Hadoop已经切换过去了，之后master1即使起来了，状态也只能为standby

5.3 Yarn访问

http://master1:8088

http://master2:8088 #会直接跳转到http://master1:8088

# Linux下访问  
[root@slave3 ~ 13:24:22]$curl master2:8088
This is standby RM. The redirect url is: http://master1:8088/

HA The End :)

附: 同步执行命令脚本sync.sh

#!/bin/bash
#变量定义
ip_array=("master2" "slave1" "slave2" "slave3") 
user="root" 
echo YOUR-CMD:[$1]
#本地通过ssh执行远程服务器的脚本
for ip in ${ip_array[*]}
    do
        ssh -t -p 22 $user@$ip "$1"
    done
#用法：./sync.sh '命令'
