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
mvn versions:set -DnewVersion=2.5.0.0.0
popd mvn -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

第二步: 安装 Ambari Server
cd apache-ambari-2.5.0-src/ambari-server/target/rpm/ambari-server/RPMS/x86_64 yum -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

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
