输入http://172.16.1.125:7180/ 用户名密码都是admin，登录后继续操作。
如果chrome登录不成功，尝试使用中文版Firefox。
登录后选择安装express版本，搜索主机时填写172.16.1.[125-127]
然后全选，在选择安装方式时选择“使用 Parcel (建议)”，然后点击后面的“更多选项”，
配置“远程 Parcel 存储库 URL” 中的第一行为：http://172.16.1.124/cdh/5/，
删除其他的“远程 Parcel 存储库 URL”，点击确定，弹出层关闭后，页面自动更新，
显示“选择 CDH 的版本”为：“CDH-5.3.0-1.cdh5.3.0.p0.30 ”
继续安装即可。
安装的时候如果遇到下面的错误：
Command failed to run because service Hive has invalid configuration. Review and correct its configuration. First error: 'Hive Metastore Database Host' is required when using database type 'postgresql'
返回，选择只安装HDFS，OOzie，zookeeper，HBase，Yarn等基本组件即可，Spark、Hive等可以后续再安装。
如果是后续往集群中添加机器，则可以在添加远程repo的时候，填写：http://192.168.88.35/cm/5.3.0/
已启用“透明大页面”，它可能会导致重大的性能问题。版本为“CentOS release 6.4 (Final)”且发行版为“2.6.32-358.el6.x86_64”的 Kernel 已将 enabled 设置为“[always] never”，并将 defrag 设置为“[always] never”。请运行“echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag”以禁用此设置，然后将同一命令添加到一个 init 脚本中，如 /etc/rc.local，这样当系统重启时就会予以设置。或者，升级到 RHEL 6.5 或更新版本，它们不存在此错误。将会影响到以下主机：
