二.安装和配置元数据库
详情请参考我的笔记：安装和配置元数据库。
三.Cloudera Manager 部署
安装服务前请确保你磁盘的可用空间大于50G！
1>.安装Cloudera Manager Server端（由于我们使用自建的镜像地址安装，而且也配置好了yum源，我们这里直接安装即可！）
[root@node101 ~]# yum -y install cloudera-manager-daemons cloudera-manager-server

[root@node101 ~]# yum -y install cloudera-manager-daemons cloudera-manager-server
2>.配置Cloudera Manager Server的默认堆内存大小
[root@node101 ~]# grep CMF_JAVA_OPTS /etc/default/cloudera-scm-server #Cloudera Manager默认分配的JVM堆内存是2G，某些情况下会出现OOM的情况，我们可以适当将其调大。
export CMF_JAVA_OPTS="-Xmx2G -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp"
[root@node101 ~]#
[root@node101 ~]# sed -i s'#Xmx2G#Xmx4G#' /etc/default/cloudera-scm-server #我们将Cloudera Manager的堆内存调大到4G。
[root@node101 ~]#
[root@node101 ~]# grep CMF_JAVA_OPTS /etc/default/cloudera-scm-server
export CMF_JAVA_OPTS="-Xmx4G -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp"
[root@node101 ~]#
[root@node101 ~]#
3>.初始化数据库配置
Cloudera官网已经提供了一个sh脚本用户配置Cloudera Manager连接元数据库，官方文档参考：
我们的安装规划下，元数据库和Cloudera Manager运行于同一个节点，且已经预先创建了scm库和用户，因此，命令很简单，具体操作如下：
[root@node101 ~]# /usr/share/cmf/schema/scm_prepare_database.sh mysql scm scm yinzhengjie
JAVA_HOME=/usr/java/jdk1.
Verifying that we can write to /etc/cloudera-scm-server
Creating SCM configuration file in /etc/cloudera-scm-server
Executing: /usr/java/jdk1./bin/java -cp /usr/share/java/mysql-connector-java.jar:/usr/share/java/oracle-connector-java.jar:/usr/share/java/postgresql-connector-java.jar:/usr/share/cmf/schema/../lib/* com.cloudera.enterprise.dbutil.DbCommandExecutor /etc/cloudera-scm-server/db.properties com.cloudera.cmf.db.
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

打开浏览器，访问：http://node101.yinzhengjie.org.cn:7180/cmf/login，如下图所示：
四.安装CDH5.15.1
1>.登陆Cloudera Manager Server 的WebUI
2>.接受协议，点击继续
3>.选择企业版（该版本的CDH是免费的）
4>.选择CDH
5>.为 CDH 群集安装指定主机。
6>.点击更多选项
7>.选择自建的CDH Parcels包镜像地址
8>.配置Cloudera Manager Agent的地址
9>.不要选中安装oracle Java，因为我们已经安装过JDK8，选中的话会装会JDK7，直接点击继续即可！
10>.不启用单用户模式安装，直接点击继续即可
11>.提供SSH登陆凭据
12>.等待Cloudera Manager Agent 安装完成
13>.查看安装过程的日志详情
14>.安装 Cloudera Manager Agent成功（根据集群性而定，我使用的是MAC，该过程大概5～10分钟左右！）
15>.下载CDH（从我们自建的镜像地址下载）
16>.CDH安装完成，点击继续
17>.等待主机检查
18>.点击完成
19>.完成上述步骤就已经完成了CDH的安装，还有一种方法安装CDH，就是下载CDH并存放到指定目录（了解即可！）
第一步：下载CDH 5.15.1的parcels包（https://archive.cloudera.com/cdh5/parcels/5.15.1/）
第二步：将下载的rpm包存放到CM默认到目录中（/opt/cloudera/parcel-repo）

五.安装Hadoop初始化的服务
1>.选择自定义服务
2>.选择需要安装的服务，点击继续（为了减少虚拟机的开销和安装时间，我这里只演示安装zookeeper集群和hdfs集群即可！其他服务的安装方法类似）
3>.自定义角色分配
4>.审核更改（这里咱们可以修改一些默认的配置，比如hdfs的块大小，数据存储的路径等等，实验环境我们默认即可，生产环境需要根据实际情况稍作修改即可！）
5>.安装初始化服务（安装过程时间可能需要3～5分钟）
6>.服务安装完成
7>.查看Cloudera Manager的监控界面
8>.安装服务完成后，我们可以查看到剩余的可用空间
