三、搭建数据库（在主机ambari-mysql上部署）

Ambari安装会将安装等信息写入数据库，建议使用自己安装的Mysql数据库，也可以不安装而使用默认数据库PostgreSQL

版本要求：-PostgreSQL8-PostgreSQL9.1.13+,9.3,9.4***-MariaDB10*-MySQL5.6-Oracle11gr2-Oracle12c**

按你系统来选择源：http://downloads.mariadb.org/mariadb/repositories/

$sudoyuminstallMariaDB-serverMariaDB-clientIfyouhaven'talreadyacceptedtheMariaDBGPGkey,youwillbepromptedtodoso.See"InstallingMariaDBwithyum"fordetailedinformation.

安装完成后创建ambari数据库及用户，登录root用户执行下面语句：createdatabaseambaricharactersetutf8;?CREATEUSER'ambari'@'%'IDENTIFIEDBY'Ambari-123';GRANTALLPRIVILEGESON*.*TO'ambari'@'%';FLUSHPRIVILEGES;

如果要安装Hive，再创建Hive数据库和用户再执行下面的语句：createdatabasehivecharactersetutf8;?CREATEUSER'hive'@'%'IDENTIFIEDBY'Hive-123';GRANTALLPRIVILEGESON*.*TO'hive'@'%';FLUSHPRIVILEGES;

如果要安装Oozie，再创建Oozie数据库和用户再执行下面的语句：createdatabaseooziecharactersetutf8;?CREATEUSER'oozie'@'%'IDENTIFIEDBY'Oozie-123';GRANTALLPRIVILEGESON*.*TO'oozie'@'%';FLUSHPRIVILEGES;

四、制作本地源(在SY-001.hadoop部署)

下载AmbariHDPHDP-UTILS源包（文件很大，需要很长下载时间，请耐心等待。。。）$cd/usr/local/src/Ambari/$wgethttp://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.4.2.0/ambari-2.4.2.0-centos7.tar.gz$wgethttp://public-repo-1.hortonworks.com/HDP/centos7/2.x/updates/2.5.3.0/HDP-2.5.3.0-centos7-rpm.tar.gz$wgethttp://public-repo-1.hortonworks.com/HDP-UTILS-1.1.0.21/repos/centos7/HDP-UTILS-1.1.0.21-centos7.tar.gz

安装本地源制作相关工具$yuminstallyum-utilscreaterepo-y

安装httpd服务$yuminstallhttpd-y$systemctlenablehttpd&&systemctlstarthttpd$cd/var/www/html/&&mkdirambari$cd/usr/local/src/Ambari/$tarxfambari-2.4.2.0-centos7.tar.gz-C/var/www/html/ambari/$tarxfHDP-2.5.3.0-centos7-rpm.tar.gz-C/var/www/html/ambari/$tarxfHDP-UTILS-1.1.0.21-centos7.tar.gz-C/var/www/html/ambari/

验证httd网站是否可用，可以使用links命令或者浏览器直接访问下面的地址：$linkshttp://172.19.80.2/ambari/结果是看到刚才解压的目录

五、安装Ambari(在SY-001.hadoop部署)

安装Ambari$yuminstallambari-server-y

配置Ambari$ambari-serversetup

下面是配置执行流程，按照提示操作（1）提示是否自定义设置。输入：yCustomizeuseraccountforambari-serverdaemon[y/n](n)?y

（2）ambari-server账号。输入：ambariEnteruseraccountforambari-serverdaemon(root):ambariAdjustingambari-serverpermissionsandownership...

（3）设置JDK。输入：3CheckingJDK...DoyouwanttochangeOracleJDK[y/n](n)?y[]OracleJDK1.8+JavaCryptographyExtension(JCE)PolicyFiles8[]OracleJDK1.7+JavaCryptographyExtension(JCE)PolicyFiles7[]CustomJDK==============================================================================Enterchoice(1):3

（4）如果上面选择3自定义JDK,则需要设置JAVA_HOME。输入：/opt/java/jdk1.8.0_112WARNING:JDKmustbeinstalledonallhostsandJAVA_HOMEmustbevalidonallhosts.WARNING:JCEPolicyfilesarerequiredforconfiguringKerberossecurity.IfyouplantouseKerberos,pleasemakesureJCEUnlimitedStrengthJurisdictionPolicyFilesarevalidonallhosts.PathtoJAVA_HOME:/opt/java/jdk1.8.0_112ValidatingJDKonAmbariServer...done.Completingsetup...

（5）数据库配置。选择：yConfiguringdatabase...Enteradvanceddatabaseconfiguration[y/n](n)?y

（6）选择数据库类型。输入：3Configuringdatabase...==============================================================================Chooseoneofthefollowingoptions:[1]-PostgreSQL(Embedded)[2]-Oracle[3]-MySQL[4]-PostgreSQL[5]-MicrosoftSQLServer(TechPreview)[6]-SQLAnywhere==============================================================================Enterchoice(3):3

（7）设置数据库的具体配置信息，根据实际情况输入，如果和括号内相同，则可以直接回车。Hostname(localhost):Port():Databasename(ambari):Username(ambari):EnterDatabasePassword(Ambari-123):

（8）将Ambari数据库脚本导入到数据库如果使用自己定义的数据库，必须在启动Ambari服务之前导入Ambari的sql脚本

用Ambari用户（上面设置的用户）登录mysqlmysql-uambari-puseambarisource/var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql

（9）启动Amabri$ambari-serverstart

（10）成功启动后在浏览器输入Ambari地址：
