前期博客

# [Ambari安装之部署单节点集群][Ambari] #

其实，按照这个步骤是一样的。只是按照好3个节点后，再做下HA即可。

## 部署3个节点的HA分布式集群 ##

（1）添加机器

和添加服务的操作类似，如下图

![855959-20170401094429477-1484111006.png][]

之后的添加ambari03、ambari04操作就和部署ambari02类似，可以参照前面的步骤。这里不多赘述。

![855959-20170406151608675-570629403.png][]

（2）添加服务

添加ambari03、ambari04的服务的操作和前面的ambari02类似，具体可以参照前面的步骤。这里不多赘述。

# [Ambari安装之部署单节点集群][Ambari] #

**　当然，我下面这里就是，ambigdata1、ambigdata2、ambigdata3和ambigdata4，组成的4节点的HA大数据集群。**

我这里，就吧所有的服务都加进去。

![855959-20170624185434398-1301979805.png][]

![855959-20170624185446898-1245544413.png][]

（3）配置HA

选择，HDFS   ->  services  ->    service actions    ->  enable namenode HA

YARN  ->   services  ->    service actions    ->enable resourcemanager HA

以后再贴图。

接下来按照命令提示一步一步操作即可

这里，大家，如何控制下呢？

![855959-20170624191102195-535226621.png][]

比如，这里，我参考这篇博客

# [完全分布式Hadoop集群的安装搭建和配置（4节点）][Hadoop_4] #

![855959-20170624191511007-1473439929.png][]

在这里，为了今年实验室环境所需。所以，将计算节点动态设置为4。来迎合论文里的4、3、2和1节点，对比加速比。

则最后得到，是如下

![855959-20170624192546148-596706183.png][]

![855959-20170624192443976-1454147636.png][]

![855959-20170624192623773-166455080.png][]

![855959-20170624210550023-137892858.png][]

![855959-20170624193609101-1153858275.png][]

![855959-20170624193625179-707315895.png][]

![855959-20170624193831991-342559344.png][]

![855959-20170624194056991-1515496111.png][]

![855959-20170624194319413-1156697148.png][]

然后，下面就是，等同于apache版本的hive安装的配置文件hive-site.xml

![855959-20170624194435101-114332248.png][]

![855959-20170624194536632-1149224073.png][]

![855959-20170624194701429-2092236375.png][]

![855959-20170624194737491-89831711.png][]

然后呢，相信大部分博友，跟我一样，在这里，对下面三个现在，都不知道怎么设置。没关系，大家，可以先跳过。

![855959-20170624195322366-2114363748.png][]

![855959-20170624195856913-529751860.png][]

![855959-20170624195356570-1353860046.png][]

以后，再回来设置即可。这个不难。

![855959-20170624195525054-927288788.png][]

![855959-20170624195837210-127415465.png][]

![855959-20170624195934741-835834781.png][]

![855959-20170624200433601-346725777.png][]

保证所有服务都正常启动之后，下面我们就可以上传文件到HDFS，并运行Mapreduce了

![855959-20170624200616351-801134887.png][]

那就改成mysql数据库来吧

![855959-20170624200713382-329410294.png][]

这里啊，我查了下资料

数据库要求

Hive/HCatalog、Oozie和Ambari都需要一个内部数据库。

Hive/HCatalog：默认使用Ambari自带的Mysql5.x。也可以自己配置Oracle 11g r2。

Oozie：默认使用Ambari自带的Derby。也可以自己配置Mysql5.x和Oracle 11g r2。

Ambari：默认使用Ambari自带的PostgreSQL8.x，也可以使用Oracle 11g r2.

![855959-20170624201137913-660326268.png][]

![855959-20170624201200023-141266590.png][]

然后

![855959-20170624201255085-2123191110.png][]

![855959-20170624201317976-773664829.png][]

![855959-20170624201330398-4638739.png][]

http://192.168.86.21:8080/#installer/step8

![855959-20170624201344851-93474785.png][]

比如这不，有个什么Hcat client安装失败。**多刷新，反复这里就是。（因为是网速原因）**

![855959-20170624212759663-318175172.png][]

最后，一定会成功，全部安装完全的！

![855959-20170624223723632-945196563.png][]

**　　如下是我开启全部服务的过程：**

![855959-20170624224137116-1078359445.png][]

![855959-20170624224001616-937069222.png][]

![855959-20170624224057913-793866840.png][]

![855959-20170624224156148-151848785.png][]

![855959-20170624224242007-1023963044.png][]

![855959-20170624231320788-2011850301.png][]

![855959-20170624231402570-1472450737.png][]

![855959-20170624232308398-2144060042.png][]

对于这样的日志报错  
一般是怎么看的，请问

jdbc驱动没有。传个上去

![855959-20170624234302757-863720781.png][]

![855959-20170624234429335-382117762.png][]

手动安装apahce版本的oozie和cdh的oozie，我会下面的这篇博客就是已经解决了

# [Oozie安装时放置Mysql驱动包的总结（网上最全）][Oozie_Mysql] #

现在，这里是ambari里安装oozie，一直不知道怎么放mysql-con\*\*驱动jar包，

以后你有时间解决下！！！

其实，很简单

[root@ambigdata1 ~]# yum install mysql-connector-java
    Is this ok [y/N]: y

即可

心得：一般在公司里，是，开启了服务，就不需再关闭。

只有自己的电脑，比如搭建了4个虚拟机这样的来，关闭再开启。

好啦，写这篇博客是为了帮助入门的博友们，同时，也是，为了最近要在自己实验室，搭建真实物理机器的多节点大数据集群!

（4）运行MapReduce程序

1）上传文件到HDFS

执行命令：cd /usr/hdp/current/hadoop-client/bin这个目录下创建vi wc.txt这个文件,然后输入相应的内容

执行命令：**sudo -u hdfs hadoop fs -put wc.txt /hdpCluster**

文件上传成功之后就可以执行命令运行mapreduce程序了，运行如下命令

yarn jar /usr/hdp/current/hadoop-mapreduce-client/hadoop-mapeduce-examples-2.7.1.2.4.0-169.jar   wordcount   /hdpCluster/wc.txt   /output

可能会报权限的问题，那么我们只需要修改一下对应的权限即可，例如使用下面的方法。

sudo  -u  hdfs  hadoop fs -ls /

sudo -u  hdfs  hadoop  fs  -chown -R  hadoop:hadoop   /

sudo  -u  hdfs  hadoop  fs  -ls  /

Mapreduce执行成功之后通过如下命令查看程序运行结果

sudo  -u  hdfs  hadoop  fs -cat  /output/part\*

那么到此为止我们的ambari安装部署HA分布式集群就给大家演示完毕了!
