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 Resolving Dependencies --> Running transaction check ---> Package ambari-server.x86_64 0:2.6.0.0-267 will be installed --> Processing Dependency: postgresql-server >= 8.1 for package: ambari-server-2.6.0.0-267.x86_64 --> Running transaction check ---> Package postgresql-server.x86_64 0:9.2.24-1.el7_5 will be installed --> Processing Dependency: postgresql-libs(x86-64) = 9.2.24-1.el7_5 for package: postgresql-server-9.2.24-1.el7_5.x86_64 --> Processing Dependency: postgresql(x86-64) = 9.2.24-1.el7_5 for package: postgresql-server-9.2.24-1.el7_5.x86_64 --> Processing Dependency: libpq.so.5()(64bit) for package: postgresql-server-9.2.24-1.el7_5.x86_64 --> Running transaction check ---> Package postgresql.x86_64 0:9.2.24-1.el7_5 will be installed ---> Package postgresql-libs.x86_64 0:9.2.24-1.el7_5 will be installed --> Finished Dependency Resolution Dependencies Resolved ====================================================================================================================================== Package Arch Version Repository Size ====================================================================================================================================== Installing: ambari-server x86_64 2.6.0.0-267 ambari-2.6.0.0 712 M Installing for dependencies: postgresql x86_64 9.2.24-1.el7_5 base 3.0 M postgresql-libs x86_64 9.2.24-1.el7_5 base 234 k postgresql-server x86_64 9.2.24-1.el7_5 base 3.8 M Transaction Summary ====================================================================================================================================== Install 1 Package (+3 Dependent packages) Total download size: 720 M Installed size: 809 M Downloading packages: (1/4): postgresql-libs-9.2.24-1.el7_5.x86_64.rpm | 234 kB 00:00:00 (2/4): postgresql-server-9.2.24-1.el7_5.x86_64.rpm | 3.8 MB 00:00:04 warning: /var/cache/yum/x86_64/7/ambari-2.6.0.0/packages/ambari-server-2.6.0.0-267.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 07513cad: NOKEY Public key for ambari-server-2.6.0.0-267.x86_64.rpm is not installed (3/4): ambari-server-2.6.0.0-267.x86_64.rpm | 712 MB 00:00:09 (4/4): postgresql-9.2.24-1.el7_5.x86_64.rpm | 3.0 MB 00:00:31 -------------------------------------------------------------------------------------------------------------------------------------- Total 22 MB/s | 720 MB 00:00:32 Retrieving key from http://node101.yinzhengjie.org.cn/ambari/ambari/centos7/2.6.0.0-267/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins Importing GPG key 0x07513CAD: Userid : "Jenkins (HDP Builds) <jenkin@hortonworks.com>" Fingerprint: df52 ed4f 7a3a 5882 c099 4c66 b973 3a7a 0751 3cad From : http://node101.yinzhengjie.org.cn/ambari/ambari/centos7/2.6.0.0-267/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : postgresql-libs-9.2.24-1.el7_5.x86_64 1/4 Installing : postgresql-9.2.24-1.el7_5.x86_64 2/4 Installing : postgresql-server-9.2.24-1.el7_5.x86_64 3/4 Installing : ambari-server-2.6.0.0-267.x86_64 4/4 Verifying : postgresql-server-9.2.24-1.el7_5.x86_64 1/4 Verifying : postgresql-libs-9.2.24-1.el7_5.x86_64 2/4 Verifying : ambari-server-2.6.0.0-267.x86_64 3/4 Verifying : postgresql-9.2.24-1.el7_5.x86_64 4/4 Installed: ambari-server.x86_64 0:2.6.0.0-267 Dependency Installed: postgresql.x86_64 0:9.2.24-1.el7_5 postgresql-libs.x86_64 0:9.2.24-1.el7_5 postgresql-server.x86_64 0:9.2.24-1.el7_5 Complete!

三.部署mysql数据库
部署mysql倒是很简单，建议大家部署mysql 的主从同步，以保证数据库的高可用性。

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 ~]# [root@node101 ~]# cp /usr/share/java/mysql-connector-java.jar /var/lib/ambari-server/resources/mysql-jdbc-driver.jar [root@node101 ~]# [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！）
[root@node101 ~]# ambari-server setup Using python /usr/bin/python Setup ambari-server Checking SELinux... SELinux status is 'disabled' Customize user account for ambari-server daemon [y/n] (n)? y #这里咱们可以自定义Ambari的用户，我们输入y就直接可以自定义啦！ Enter user account for ambari-server daemon (root):ambari #我们看到了括号里的用户为默认用户，及默认用户是root用户！我们这里自定义管理Ambari的用户为ambari Adjusting ambari-server permissions and ownership...

Adjusting ambari-server permissions and ownership... Ambari Server 'setup' completed successfully. #当你看到这一行时，说明你配置的整个过程都是一路绿灯的，接下来就可以开启Ambari服务啦！ [root@node101 ~]#
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 Using python /usr/bin/python Starting ambari-server Ambari Server running with administrator privileges. Organizing resource files at /var/lib/ambari-server/resources... Ambari database consistency check started... Server PID at: /var/run/ambari-server/ambari-server.pid Server out at: /var/log/ambari-server/ambari-server.out Server log at: /var/log/ambari-server/ambari-server.log #这个文件是存放日志的，上面2个文件存放的是PID以及 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
