安装并配置Ambari-server
（1）检查仓库是否可用
[hadoop@ambari01 yum.repos.d]$ pwd /etc/yum.repos.d [hadoop@ambari01 yum.repos.d]$ yum repolist Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile * base: centos.ustc.edu.cn * extras: centos.ustc.edu.cn * updates: mirrors.zju.edu.cn Updates-ambari-2.2.1.0 | 2.9 kB 00:00 Updates-ambari-2.2.1.0/primary_db | 89 kB 00:00 repo id repo name status Updates-ambari-2.2.1.0 ambari-2.2.1.0 - Updates 229 base CentOS-6 - Base 6,696 extras CentOS-6 - Extras 64 updates CentOS-6 - Updates 974 repolist: 7,963 [hadoop@ambari01 yum.repos.d]$
（2）安装Ambari-server
[hadoop@ambari01 yum.repos.d]$ pwd /etc/yum.repos.d [hadoop@ambari01 yum.repos.d]$ sudo yum install ambari-server Loaded plugins: fastestmirror, refresh-packagekit, security Setting up Install Process Loading mirror speeds from cached hostfile * base: mirrors.zju.edu.cn * extras: mirrors.zju.edu.cn * updates: mirrors.zju.edu.cn Updates-ambari-2.2.1.0 | 2.9 kB 00:00 Updates-ambari-2.2.1.0/primary_db | 89 kB 00:00 Resolving Dependencies --> Running transaction check ---> Package ambari-server.x86_64 0:2.2.1.0-161 will be installed --> Processing Dependency: postgresql-server >= 8.1 for package: ambari-server-2.2.1.0-161.x86_64 --> Running transaction check ---> Package postgresql-server.x86_64 0:8.4.20-6.el6 will be installed --> Processing Dependency: postgresql-libs(x86-64) = 8.4.20-6.el6 for package: postgresql-server-8.4.20-6.el6.x86_64 --> Processing Dependency: postgresql(x86-64) = 8.4.20-6.el6 for package: postgresql-server-8.4.20-6.el6.x86_64 --> Processing Dependency: libpq.so.5()(64bit) for package: postgresql-server-8.4.20-6.el6.x86_64 --> Running transaction check ---> Package postgresql.x86_64 0:8.4.20-6.el6 will be installed ---> Package postgresql-libs.x86_64 0:8.4.20-6.el6 will be installed --> Finished Dependency Resolution Dependencies Resolved =============================================================================================================================================================================================== Package Arch Version Repository Size =============================================================================================================================================================================================== Installing: ambari-server x86_64 2.2.1.0-161 Updates-ambari-2.2.1.0 409 M Installing for dependencies: postgresql x86_64 8.4.20-6.el6 base 2.6 M postgresql-libs x86_64 8.4.20-6.el6 base 202 k postgresql-server x86_64 8.4.20-6.el6 base 3.4 M Transaction Summary =============================================================================================================================================================================================== Install 4 Package(s) Total download size: 415 M Installed size: 464 M Is this ok [y/N]: y Downloading Packages: (1/4): ambari-server-2.2.1.0-161.x86_64.rpm | 409 MB 00:22 (2/4): postgresql-8.4.20-6.el6.x86_64.rpm | 2.6 MB 00:02 (3/4): postgresql-libs-8.4.20-6.el6.x86_64.rpm | 202 kB 00:00 (4/4): postgresql-server-8.4.20-6.el6.x86_64.rpm | 3.4 MB 00:03 ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Total 14 MB/s | 415 MB 00:29 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : postgresql-libs-8.4.20-6.el6.x86_64 1/4 Installing : postgresql-8.4.20-6.el6.x86_64 2/4 Installing : postgresql-server-8.4.20-6.el6.x86_64 3/4 Installing : ambari-server-2.2.1.0-161.x86_64 4/4 Verifying : postgresql-server-8.4.20-6.el6.x86_64 1/4 Verifying : postgresql-8.4.20-6.el6.x86_64 2/4 Verifying : postgresql-libs-8.4.20-6.el6.x86_64 3/4 Verifying : ambari-server-2.2.1.0-161.x86_64 4/4 Installed: ambari-server.x86_64 0:2.2.1.0-161 Dependency Installed: postgresql.x86_64 0:8.4.20-6.el6 postgresql-libs.x86_64 0:8.4.20-6.el6 postgresql-server.x86_64 0:8.4.20-6.el6 Complete! [hadoop@ambari01 yum.repos.d]$
（3）配置Ambari-server
[hadoop@ambari01 yum.repos.d]$ pwd /etc/yum.repos.d [hadoop@ambari01 yum.repos.d]$ sudo ambari-server setup Using python /usr/bin/python2 Setup ambari-server Checking SELinux...

[hadoop@ambari01 yum.repos.d]$
注意：
如果你是root用户，则这里就写root （推荐）
好比我这里是hadoop用户，则这里就写hadoop（不建议）
（4）查看并启动Ambari-server
[hadoop@ambari01 yum.repos.d]$ sudo service ambari-server status Using python /usr/bin/python2 Ambari-server status Ambari Server not running. Stale PID File at: /var/run/ambari-server/ambari-server.pid [hadoop@ambari01 yum.repos.d]$ sudo service ambari-server start Using python /usr/bin/python2 Starting ambari-server Ambari Server running with administrator privileges. Organizing resource files at /var/lib/ambari-server/resources... 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 Waiting for server start.................... Ambari Server 'start' completed successfully. [hadoop@ambari01 yum.repos.d]$
（5）在C:\Windows\System32\drivers\etc目录下配置hosts文件
（6）输入地址登录ambari
默认的用户名和密码都为admin
登录之后的界面如下
那么到此为止，我们集群部署前的所有准备工作就做好了，接下来我们就可以部署hadoop集群了。
