一.环境准备

 　　详情请参考我之前的笔记：离线方式部署Ambari2.6.0.0 中关于第三步和第四步的操作。

 

二.安装ambari-server（需要配置好本地yum源哟～也就是第一步骤） 

[root@node101 ~]# yum -y install ambari-server
Loaded plugins: fastestmirror, priorities
Loading mirror speeds from cached hostfile
 * base: mirrors.aliyun.com
 * extras: mirrors.tuna.tsinghua.edu.cn
 * updates: mirrors.tuna.tsinghua.edu.cn
23 packages excluded due to repository priority protections

4>.初始化Ambari的数据库表（本篇博客没有安装hive,oozie之类的服务， 如果你要部署他们，只需要创建对应的数据库并授权用户名和密码即可！下面我给出了案例！）

[root@node101 ~]# cat yinzhengjie-hdp.sql   　　　　　　　　　　　　　　　　　　　　　　　　#注意，下面的mysql命令都很简单，我就不多费口舌啦，你只需要根据自己的环境做适当的调整即可。
CREATE DATABASE ambari;  
use ambari;

FLUSH PRIVILEGES;

show tables;

[root@node101 ~]# mysql -uroot -pyinzhengjie < yinzhengjie-hdp.sql　　　　　　　　　　　　#初始化mysql的数据库，主要就是一系列的建表操作，好啦～接下来就开始你的表演吧！

5>.下载mysql的驱动到ambari-server的依赖库中

[root@node101 ~]# mkdir  /usr/share/java
[root@node101 ~]# 
[root@node101 ~]# cp mysql-connector-java-5.1.26.jar /usr/share/java/mysql-connector-java.jar

[root@node101 ~]# echo "server.jdbc.driver.path=/usr/share/java/mysql-connector-java.jar" >> /etc/ambari-server/conf/ambari.properties
[root@node101 ~]# 

  

三.使用mysql存放Ambari元数据的配置

1>.初始化设置ambari-server（这个步骤必须先做，如果跳过这个步骤启动ambari-server会报错的！）

2>.启动ambari-seriver服务 

[root@node101 ~]# ambari-server start　　　　　　　　　　　　　　　　　　　　　　　#输入相应的启动命令，你就会发现启动数据是成功的

Waiting for server start......................
Server started listening on 8080　　　　　　　　　　　　　　　　　　　　　　　　　　#这里自然就是监听服务的端口啦～我们可以通过webUI的方式去访问它。

DB configs consistency check: no errors and warnings were found.
Ambari Server 'start' completed successfully.　　　　　　　　　　　　　　　　　　#这里提示我们服务启动成功啦～
[root@node101 ~]#

　　好啦，既然服务已经启动成功了，那我们也别闲着了，说干就干吧，访问一下WebUI吧：

 

 　　如上图所示，登陆系统之后，会看到Ambari空空如也的欢迎界面，接下来我们就需要介绍如何通过Ambari新建Hadoop集群。详情请参考我的博客：手把手教你通过Ambari新建Hadoop集群图解案例。

 

四. 重置ambari-server的方法

　　如果出现错误，请注意查看日志，根据具体的错误内容进行处理，默认ambari-server的日志在/var/log/ambari-server/ambari-server.log里面。如果在处理日志的过程中或者后面安装的过程中出现一些莫名的错误，可以重置的安装。如果上面进行的默认数据库的配置，可以使用下面的代码重置ambari-server：

[root@yinzhengjie ~]# ambari-server stop　　　　　　#停止ambari-server服务
[root@yinzhengjie ~]# ambari-server reset　　　　　　#重置ambari-server服务
[root@yinzhengjie ~]# ambari-server setup　　　　　　#重复第二和三步骤，对使用mysql存放元数据信息。但在吃之前，你创建对数据库表之类需要删除，或者你创建新对数据库，在配置对时候自定义指定都是可以的！

　如果在安装的过程中出现了错误，又想重新安装，可以在ambari-server开启的情况下，执行下面的语句来移除已安装的包，然后再通过不同的情况选择上面两种方式的一种对ambari-server进行重置

[root@node101 ~]# python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py --silent
