Hadoop zookeeper hbase spark phoenix (HA)搭建过程

环境介绍:

系统:centos7

软件包:

hadoop-3.1.1.tar.gz 下载链接:http://mirror.bit.edu.cn/apache/hadoop/core/hadoop-3.1.1/hadoop-3.1.1.tar.gz

hbase-1.4.8-bin.tar.gz 下载链接:http://mirror.bit.edu.cn/apache/hbase/1.4.9/hbase-1.4.9-bin.tar.gz

jdk-8u181-linux-x64.tar.gz 下载链接:https://download.oracle.com/otn-pub/java/jdk/8u191-b12/2787e4a523244c269598db4e85c51e0c/jdk-8u191-linux-x64.tar.gz

spark-2.1.0-bin-hadoop2.7.tgz 下载链接:http://mirror.bit.edu.cn/apache/spark/spark-2.1.3/spark-2.1.3-bin-hadoop2.7.tgz

 zookeeper-3.4.13.tar.gz   下载链接:http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gz

注:链接版本跟我现在使用的版本可能会有稍微差别,不过不影响,只是小版本号差那么一点,大版本号号还是一样的,这里使用最新的hadoop3.11版本。

资源关系:这里使用的主机名跟我待会使用的主机名不一样,毕竟生产环境,集群配置涉及到主机名和ip都会相应的变化。但是效果是一样的。

主机名 ip                      
zk1 10.62.2.1 jdk8 zookeeper namenode1 journalnode1   resourcemanager1   Hmaster      
zk2 10.62.2.2 jdk8 zookeeper namenode2 journalnode2   resourcemanager2   Hmaster-back      
zk3 10.62.2.3 jdk8 zookeeper namenode3 journalnode3           spark-master phoenix
yt1 10.62.3.1 jdk8       datanode1       HRegenServer1    
yt2 10.62.3.2 jdk8       datanode2       HRegenServer2    
yt3 10.62.3.3 jdk8       datanode3       HRegenServer3    
yt4 10.62.3.4 jdk8       datanode4            
yt5 10.62.3.5 jdk8       datanode5         spark-work1  
yt6 10.62.3.6 jdk8       datanode6         spark-work2  
yt7 10.62.3.7 jdk8       datanode7         spark-work3  
yt8 10.62.3.8 jdk8       datanode8         spark-work4  
yt9 10.62.3.9 jdk8       datanode9   nodemanager1        
yt10 10.62.3.10 jdk8       datanode10   nodemanager2        

前期准备:1、配置ip,关闭防火墙或者设置相应的策略,关闭selinux,设置主机之间相互ssh免密,创建用户等,这里不在多说。以下操作全是非root用户

配置ssh免密需要注意一点:如果你的主机之间不是默认的22端口,那么在设置ssh免密的时候需要修改/etc/ssh/ssh_config配置文件

$ vim /etc/ssh/ssh_config
在文件最后添加
Port ssh的端口
比如我的ssh端口是9222

 

然后重新启动ssh服务

 一、zookeeper安装

1、解压zookeeper包到相应的目录,进入到解压的目录

1、解压
$ tar zxvf zookeeper-3.4.13.tar.gz -C /data1/hadoop/hadoop/
$ mv zookeeper-3.4.13/ zookeeper
2、修改环境变量:
在~/.bashrc文件添加

  export ZOOK=/data1/hadoop/zookeeper-3.4.13/
  export PATH=$PATH:${ZOOK}/bin

  $ source ~/.bashrc

3、修改配置文件
$ cd zookeeper/conf
$ cp zoo_sample.cfg  zoo.cfg
修改成如下:

如果要自定义日志文件,仅仅在改配置文件修改并不好使,还得修改./bin/zkEnv.sh 这个文件,修改如下:

4、创建数据目录和日志目录

$ mkdir /data1/hadoop/data/zookeeper/data/zdata -p

$ mkdir /data1/hadoop/data/zookeeper/logs -p

5、创建myid文件

$ echo 1 > /data1/hadoop/data/zookeeper/data/zdata/myid

6、分发到另外的两台机器

$ scp -r zk2:/data1/hadoop/data/zookeeper/ (注意,这里已经做完免密了,不需要再输入密码)

$ scp -r zk3:/data1/hadoop/data/zookeeper/

7、当然,还得去zk2上执行  $ echo 2 > /data1/hadoop/data/zookeeper/data/zdata/myid

去zk3上执行  $ echo 3 > /data1/hadoop/data/zookeeper/data/zdata/myid

8、接下来分别到这三台机器执行

$ zkServer.sh start (我已经添加了环境变量,如果未添加需要到bin目录下执行该脚本文件)

如果不出意外,执行成功是最好的

10、查看状态:zkServer.sh status

如果最后状态是一个leader,两个follower就代表成功。

11、启动失败原因(有可能全部没有启动成功,有可能启动其中一个或者两个)

(1)、防火墙没有停掉或者策略配置有问题

(2)、配置文件错误,尤其是myid文件

(3)、selinux没设置成disabled或者permissive

(4)、端口被占用

(5)、启动以后监听的是ipv6地址,如下:(这是最坑的,我在这里卡了好久)

正常情况下应该是tcp不是tcp6

解决办法就是关闭ipv6,然后重新启动zookeeper。

 2、配置jdk,解压然后配置~/.source文件就可以,不在多说

3、hadoop(HA)(zk1机器操作)

1、解压
$ tar zxvf hadoop-3.1.1.tar.gz -C /data1/hadoop/
$ mv hadoop-3.1.1 hadoop
$ cd /data1/hadoop/hadoop/etc/hadoop/
2、配置环境变量~/.source

  export HADOOP_HOME=/data1/hadoop/hadoop
  export PATH=$PATH:${HADOOP_HOME}/bin:${HADOOP_HOME}/sbin

  3、配置hadoop-env.sh,添加Java环境变量,文件最后添加:

  export JAVA_HOME=/usr/local/jdk/

  4、配置core-site.xml,如下:(具体配置还得根据自己实际情况,这里可以做一个参考)

<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://TEST</value>
</property>
<property>
<name>io.file.buffer.size</name>

<value>5120</value>
</property>

<property>
<name>mapreduce.map.java.opts</name>

<value>zk1:11211</value>
</property>

<property>
<name>mapreduce.job.queuename</name>
<value>hadoop</value>
</property>

  8、配置capacity-scheduler.xml(自己测试可以不用配置),如下:

<configuration>
<property>
<name>yarn.scheduler.capacity.root.queues</name>
<value>default,hadoop,orc</value>
</property>

<property>
<name>yarn.scheduler.capacity.root.default.capacity</name>

<value>hadoop</value>
</property>

<property>
<name>yarn.scheduler.capacity.root.hadoop.acl_administer_queue</name>
<value>hadoop</value>
</property>
</configuration>

  9、配置workers文件(注意:这是配置datanode节点的文件,以前是slaves,现在3.x变成了workers文件)

  10、分发到所有的其他机器(注:整个集群所有机器),具体情况具体分发

  $ scp -r /data1/hadoop/hadoop 其他所有机器:/data1/hadoop

  10、格式化与启动

  (1)、格式化zookeeper(zk1上格式化)

        $ hdfs zkfc -formatZK

  (2)、在zk这三台机器启动journalnode

        $ hadoop-daemon.sh start journalnode

  (3)、格式化namenode(zk1上格式化)

        $ hdfs namenode -format

  (4)、启动namenode(zk1执行)

        $ hadoop-daemon.sh start namenode

  (5)、在zk2、zk3两台机器分别执行:

        $ hdfs namenode -bootstrapStandby

  (6)、启动hdfs,执行命令 start-dfs.sh 因为我这里yt*这些机器都需要启动datanode,所以workers文件如下:      

yt1
yt2
yt3
yt4
yt5
yt6
yt7
yt8
yt9
yt10

  (7)、启动yarn,执行命令 start-yarn.sh ,因为我只启动了最后两条,所以workers文件修改如下(只需要修改zk1就行,毕竟这是主节点)

yjt9

yjt10

 (8)、查看集群状态

$ hdfs haadmin -getAllServiceState (hdfs)
zk1:9000 active
zk2:9000 standby
zk3:9000 standby

$ yarn rmadmin -getAllServiceState (yarn)
zk1:8033 active

zk2:8033 standby

 (9)、测试

       kill掉活动的节点,看是否自动转移。(这里就不测试了)

4、hbase (HA)(zk2机器操作)

1、解压
tar zxvf hbase-1.4.8-bin.tar.gz -C /data1/hadoop/
2、配置hbase-env.sh,添加环境变量如下:

export HADOOP_HOME=/data1/hadoop/hadoop
export JAVA_HOME=/usr/local/jdk
export HBASE_MANAGES_ZK=false  <!--不使用自带的zookeeper  -->

  3、配置hbase-site.xml,如下:(这里只是最简单的配置,不适合生成环境)

<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://TEST/hbase</value>
</property>

<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>

<property>
<name>hbase.zookeeper.quorum</name>
<value>zk1:2181,zk2:2181,zk3:2181</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
</property>

<property>
<name>hbase.master.port</name>
<value>60000</value>
</property>

<property>
<name>hbase.tmp.dir</name>
<value>/data1/hadoop/data/hbase/tmp/</value>
</property>

<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/data1/hadoop/data/zookeeper/data/</value>
</property>
</configuration>

  或者:(生成环境)

<configuration>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.tmp.dir</name>
<value>/data2/hadoop/data/hbase/tmp/</value>

<value>hdfs://TEST/hbase</value>
</property>
<property>

</configuration>

  4、拷贝hadoop的hdfs-site.xml和core-site.xml文件到hbase的conf目录下,或者做软连接也可以

     $ cat /data1/hadoop/hadoop/etc/hadoop/hdfs-site.xml . (点代表当前目录,因为我当前目录就是hbase的conf目录下)

     $ cat /data1/hadoop/hadoop/etc/hadoop/core-site.xml .

     或者

     $ ln -s /data1/hadoop/hadoop/etc/hadoop/hdfs-site.xml hdfs-site.xml

     $ ln -s /data1/hadoop/hadoop/etc/hadoop/core-site.xml core-site.xml

  5、配置regionservers,文件内容如下

yt1

yt2

yt3

  6、配置backup-masters(改文件需要自己创建,指定备Hmaster的节点),内容如下:

zk3

  7、分发到其他节点

  8、启动hbase(zk2执行命令就行)

     $ start-hbase.sh

  9、测试:命令行输入 hbase shell进入到hbase,执行list命令,如果不报错就成功,如下:

5、phoenix安装

1、解压
$ tar zxvf apache-phoenix-4.14.0-HBase-1.4-bin.tar.gz -C /data1/hadoop
2、把hbase配置文件hbase-site.xml拷贝到Phoenix的bin目录
3、把Phoenix下的phoenix-core-4.14.0-HBase-1.4.jar 和phoenix-4.14.0-HBase-1.4-server.jar这两个包拷贝到hbase的lib目录下(主从节点都需要),最好把
phoenix-4.14.0-HBase-1.4-server.jar这个包拷贝到整个hbase集群(包括regisonserver服务端),否则在通过phoenix连接hbase的时候,导致regisonserver挂掉,挂掉时的信息如下:

 



4、测试
$ ./bin/sqlline.py zk1,zk2,zk3:2181 指定zookeeper集群节点
连接成功以后输入!tables查看(注意命令前面有感叹号)

 6、配置spark(HA)

1、解压
$ tar zxvf spark-2.1.0-bin-hadoop2.7.tgz -C /data1/hadoop
2、配置~/.source环境变量

export SPARK_HOME=/data1/hadoop/spark
export PATH=$PATH:${SPARK_HOME}/bin:${SPARK_HOME}/sbin

  3、配置spark-env.sh,文件最后添加如下:

export JAVA_HOME=/usr/local/jdk
export HADOOP_HOME=/data1/hadoop/hadoop

export HADOOP_CONF_DIR=/data1/hadoop/hadoop/etc/hadoop
export SPARK_LOCAL_DIRS=/data1/hadoop/data/spark/local,/data1/hadoop/data/spark/local
export SPARK_WORKER_CORES=20
export SPARK_WORKER_MEMORY=100g
export SPARK_MASTER_WEBUI_PORT=8090
export SPARK_WORKER_OPTS="-Dspark.worker.cleanup.enabled=true"


export SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=zk1:2181,zk2:2181,zk3:2181 -Dspark.deploy.zookeeper.dir=/spark"

  

  4、配置slaves(指定worker节点),文件内容如下:

yjt5

yjt6

yjt7

yjt8

  

  5、配置spark-defaults.conf文件   

spark.master spark://zk2:7077,zk3:7077     -----指定spark  master的地址
spark.submit.deployMode client             -----指定spark任务提交时的模式。有standalone模式,yarn(client、cluster)、mesos
spark.eventLog.enabled true                -----是否开启事件日志
spark.eventLog.compress true               -----日志是否压缩
spark.eventLog.dir hdfs://ns1/spark/eventLog    ----指定路径,放在master节点的hdfs中,端口要跟hdfs设置的端口一致(默认为8020),否则会报错,并且在启动spark集群的时候,需要首先创建该目录,否则启动失败       
spark.serializer org.apache.spark.serializer.KryoSerializer
spark.io.compression.codec snappy
spark.shuffle.consolidateFiles true
spark.history.fs.logDirectory hdfs://ns1/spark/historyLog    ---历史日志
spark.rpc.netty.dispatcher.numThreads 2
spark.driver.memory 10g      ---driver内存
spark.driver.cores 2         ---driver使用cpu core  
spark.executor.memory 4g     ---driver使用内存

  

  5、分发到其他节点

  6、启动spark  (zk3机器执行命令)

     $ ./sbin/start-all.sh (这里只会启动一个master和其他的工作节点)

     启动另外一个master

     $ star-master.sh

 

 

7、配置过程中的一些错误

错误(1):

2018-12-19 13:20:41,444 INFO org.apache.hadoop.security.authentication.server.AuthenticationFilter: Unable to initialize FileSignerSecretProvider, falling back to use random secrets.
2018-12-19 13:20:41,446 INFO org.apache.hadoop.http.HttpRequestLog: Http request log for http.requests.datanode is not defined

2018-12-19 13:20:41,471 INFO org.apache.hadoop.http.HttpServer2: HttpServer.start() threw a non Bind IOException
java.net.BindException: Port in use: localhost:0
。。。。。。。

解决:在/etc/hosts文件添加如下两行(我在配置这个文件的时候删除了这两行,没想到居然报错了):

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

错误(2):

-ls: java.net.UnknownHostException: TEST
[hduser@ai2-log-hz logs]$ hadoop fs -ls /
2018-12-19 15:31:17,553 INFO ipc.Client: Retrying connect to server: TEST/125.211.213.133:8020. Already tried 0 time(s); maxRetries=45
2018-12-19 15:31:37,575 INFO ipc.Client: Retrying connect to server: TEST/125.211.213.133:8020. Already tried 1 time(s); maxRetries=45

我连这个ip是什么鬼都不知道,居然报这个错:

解决:在hdfs-site.xml文件添加下面这个配置,如果原本就有,还是报这个错,那说明这个配置你应该是配置错了;注意下面标红的地方,我最开始就配置失误了,这个该是你hdfs集群的名字

<property>
<name>dfs.client.failover.proxy.provider.TEST</name>
<value>org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider</value>
</property>

错误(3):

当hdfs或者yarn集群的active节点挂掉以后,活动不能自动转移:

解决:

(1)查看系统是否有fuser命令,如果没有请执行下面这个命令安装:

    $ sudo yum install -y psmisc

 (2) 修改hdfs-site.xml配置文件,添加标红的配置,一般来说配置这个文件都没有配置这个值,当然,我前面配置hdfs-site.xml已经配置好了

<property>
<name>dfs.ha.fencing.methods</name>
<value>sshfence
shell(/bin/true)   
</value>

 

注意:如果是root用户 操作,启动进程会报错,如下:

[root@master hadoop]# start-dfs.sh 
Starting namenodes on [master slave1]
ERROR: Attempting to operate on hdfs namenode as root
ERROR: but there is no HDFS_NAMENODE_USER defined. Aborting operation.
Starting datanodes
ERROR: Attempting to operate on hdfs datanode as root
ERROR: but there is no HDFS_DATANODE_USER defined. Aborting operation.
Starting journal nodes [slave2 slave1 master]
ERROR: Attempting to operate on hdfs journalnode as root
ERROR: but there is no HDFS_JOURNALNODE_USER defined. Aborting operation.
Starting ZK Failover Controllers on NN hosts [master slave1]
ERROR: Attempting to operate on hdfs zkfc as root
ERROR: but there is no HDFS_ZKFC_USER defined. Aborting operation.

启动yarn进程也同样会报错

解决:在start-dfs.sh,stop-dfs.sh 开始位置增加如下配置:

# 注意等号前后不要有空格
HDFS_NAMENODE_USER=root
HDFS_DATANODE_USER=root
HDFS_JOURNALNODE_USER=root
HDFS_ZKFC_USER=root

同样,在yarn的start-yarn.sh,stop-yarn.sh开始位置添加:

# 注意等号前后不要有空格
YARN_RESOURCEMANAGER_USER=root
YARN_NODEMANAGER_USER=root

现在去启动就不会报错了。

 

ok!!!
