Ambari 是什么

Ambari 的作用来就是创建、管理、监视 Hadoop 集群，但是这里的 Hadoop 是广义，指的是 Hadoop 整个生态圈（例如 Hive，Hbase，Sqoop，Zookeeper 等），而并不仅是特指 Hadoop。用一句话来说，Ambari 就是为了让 Hadoop 以及相关的大数据软件更容易使用的一个工具。
Ambari 自身也是一个分布式架构的软件，主要由两部分组成：Ambari Server 和 Ambari Agent。简单来说，用户通过 Ambari Server 通知 Ambari Agent 安装对应的软件；Agent 会定时地发送各个机器每个软件模块的状态给 Ambari Server，最终这些状态信息会呈现在 Ambari 的 GUI，方便用户了解到集群的各种状态，并进行相应的维护

Ambari 2.5.0源码编译安装

三台机器(centeros)分别是m1、m2、m3，m1为Ambari Server，m2、m3为Ambari Agent

Ambari 2.5.0源码编译安装
三台机器(centeros)分别是m1、m2、m3，m1为Ambari Server，m2、m3为Ambari Agent
准备工作：
1、SSH 的无密码登录
Ambari 的 Server 会 SSH 到 Agent 的机器，拷贝并执行一些命令。因此我们需要配置 Ambari Server 到 Agent 的 SSH 无密码登录。在这里就是，m1可以 SSH 无密码登录 m2 和 m3

2、确保 Yum 可以正常工作
通过公共库（public repository），安装 Hadoop 这些软件，背后其实就是应用 Yum 在安装公共库里面的 rpm 包。所以这里需要您的机器都能访问 Internet。

3、确保机器的 Python 版本大于或等于 2.6

4、安装好maven

参考官网：https://cwiki.apache.org/confluence/display/AMBARI/Installation+Guide+for+Ambari+2.5.0

pushd命令常用于将目录加入到栈中，加入记录到目录栈顶部，并切换到该目录；若pushd命令不加任何参数，则会将位于记录栈最上面的2个目录对换位置

popd用于删除目录栈中的记录；如果popd命令不加任何参数，则会先删除目录栈最上面的记录，然后切换到删除过后的目录栈中的最上面的目录

预先安装的软件

第一步：下载编译 Ambari 2.5.0源码

wget http://www.apache.org/dist/ambari/ambari-2.5.0/apache-ambari-2.5.0-src.tar.gz
tar xfvz apache-ambari-2.5.0-src.tar.gz
cd apache-ambari-2.5.0-src
mvn versions:set -DnewVersion=2.5.0.0.0
pushd ambari-metrics

popdmvn -B clean install package rpm:rpm -DnewVersion=2.5.0.0.0 -DskipTests -Dpython.ver="python >= 2.6" -Drat.skip=true

第一步常见的错误

编译ambari-metrics时比较慢，主要是因为里面包含的几个文件下载时间太长，可以修改apache-ambari-2.5.0-src/ambari-metrics/pom.xml中properties属性下的文件下载地址为本地，然后，通过迅雷下载，如下

第二步: 安装 Ambari Server

cd  apache-ambari-2.5.0-src/ambari-server/target/rpm/ambari-server/RPMS/x86_64yum  -y install ambari-server*.rpm 

第三步：设置启动ambari-server（使用root进行设置和启动）

安装Mysql

yum install -y mysql-server

配置mysql数据库
启动Mysql：

 service mysqld start

连接数据库：

mysql -u root -p
create database ambari;
use ambari;
source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql
mysqladmin -u root password "root"

mysql -u root -p直接回车，此时不需要输入密码

ambari-server setup
/usr/sbin/ambari-server: line 34: buildNumber: unbound variable

脚本/usr/sbin/ambari-server中的变量buildNumber没有定义

export buildNumber=2.5.0.0
ambari-server setup

WARNING: Before starting Ambari Server, you must copy the MySQL JDBC driver JAR file to /usr/share/java and set property "server.jdbc.driver.path=[path/to/custom_jdbc_driver]" in ambari.properties.
Press <enter> to continue.

拷贝/usr/share/java，设置ambari.properties  server.jdbc.driver.path=[path/to/custom_jdbc_driver]
server.jdbc.driver.path=/usr/share/java/mysql-connector-java-5.1.42-bin.jar
ambari.properties文件在/etc/ambari-server/conf下

配置好后需要在重新的ambari-server setup一次，不然启动是不成功

ambari-server start

启动日志
/var/log/ambari-server/ambari-server-command.log

WARNING: The hostname was not found in the reverse DNS lookup. This may result in incorrect behavior

主机名有问题，在hosts文件中配置一下就好了

启动成功应该如下

[root@bogon ambari-server]# ambari-server start

web访问地址
http://192.168.1.105:8080/
用户名和密码都是admin

配置私钥的时候红色的部分也要一起拷贝

上面的错误是因为其他节点没有安装ambari-agent
