# 前言 #

之前有写过cdh5.x的安装过程，但是这次想体验下在cdh6.3.2下操作的体验，所以之后项目的操作环境都将是cdh6.3.2！但话说回来现在的cdh之后的版本都将收费，所以如果时间够充裕之后可以用apache版本去梭哈一把！！好了话不多说

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5NjU3OTA5_size_16_color_FFFFFF_t_70_pic_center]

--------------------

# 一、配置ssh #

查看：[配置ssh连接][ssh]

# 二、安装jdk #

注意：这里离线安装jdk时建议安装在/usr/java目录下因为后续启动cm时会默认会去使用/usr/java下的jdk！！  
查看：[安装jdk][jdk]

# 三、安装mysql #

查看：[内含mysql安装][mysql]  
1）配置mysql的驱动，将其拷贝至/usr/share/java路径下，并重命名

# 没有则创建
    mkdir /usr/local/java
    # 移动并重命名
    mv mysql-connector-java-5.1.27-bin.jar /usr/share/java/mysql-connector-java.jar

![在这里插入图片描述][2021062618181824.png]  
2）分发

# 创建文件夹，xcall自定义脚本可以去看下写的hadoop相关内容
    xcall mkdir /usr/local/java
    # 分发
    xsync /usr/local/java/mysql-connector-java.jar

# 四、安装cm #

其实可以参考下：[cdh5系列安装][mysql]过程其实是有些类似的  
因为只有三台机器，所以三台机器规划如下：

<table> 
 <thead> 
  <tr> 
   <th>节点</th> 
   <th>lsl101</th> 
   <th>lsl102</th> 
   <th>lsl103</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>服务</td> 
   <td>cloudera-scm-server &amp;cloudera-scm-agent</td> 
   <td>cloudera-scm-agent</td> 
   <td>cloudera-scm-agent</td> 
  </tr> 
 </tbody> 
</table>

这里是使用的离线安装cdh6.3.2,所含文件如下：![在这里插入图片描述][20210626182632782.png]

## 4.1 mysql中建库 ##

1.  创建各组件需要的数据库，

-- 注意这里的mysql密码问题。可以将密码设置为 MasterScm01#
    GRANT ALL ON scm.* TO 'scm'@'%' IDENTIFIED BY 'cscm';
    GRANT ALL ON hive.* TO 'hive'@'%' IDENTIFIED BY 'hive';
    GRANT ALL ON hue.* TO 'hue'@'%' IDENTIFIED BY 'chue';
    CREATE DATABASE scm DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE hive DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
    CREATE DATABASE oozie DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
    CREATE DATABASE hue DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

## 4.2 安装cm ##

1.  创建目录存放cdh安装文件

cd /opt/soft/
    mv cloudera-manager-agent-6.3.1-1466458.el7.x86_64.rpm /opt/cloudera-manager/
    mv cloudera-manager-server-6.3.1-1466458.el7.x86_64.rpm /opt/cloudera-manager/
    mv cloudera-manager-daemons-6.3.1-1466458.el7.x86_64.rpm /opt/cloudera-manager/
    xsync /opt/cloudera-manager

1.  安装cloudera-manager-daemons,安装完毕后多出/opt/cloudera目录,在每个机器上都执行以下命令

rpm -ivh cloudera-manager-daemons-6.3.1-1466458.el7.x86_64.rpm

1.  安装cloudera-manager-agent,在每个机器上都执行以下命令

yum install bind-utils psmisc cyrus-sasl-plain cyrus-sasl-gssapi fuse portmap fuse-libs /lib/lsb/init-functions httpd mod_ssl openssl-devel python-psycopg2 MySQL-python libxslt
    rpm -ivh cloudera-manager-agent-6.3.1-1466458.el7.x86_64.rpm

1.  安装agent的server节点,在每个机器上都执行以下命令

vim /etc/cloudera-scm-agent/config.ini
    server_host=hostname

1.  安装cloudera-manager-server,在一台机器上执行

rpm -ivh cloudera-manager-server-6.3.1-1466458.el7.x86_64.rpm

1.  上传CDH包导parcel-repo  
    ![在这里插入图片描述][20210626234157654.png]

1.  修改server的db.properties

vim /etc/cloudera-scm-server/db.properties
    # 填入如下内容
    com.cloudera.cmf.db.type=mysql
    com.cloudera.cmf.db.host=localhost
    com.cloudera.cmf.db.name=scm
    com.cloudera.cmf.db.user=scm
    com.cloudera.cmf.db.setupType=EXTERNAL
    com.cloudera.cmf.db.password=cscm

1.  启动server服务

/opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm
    systemctl start cloudera-scm-server

坑：启动后查看状态发现一直没有正常启动，后来执行journalctl -xe 命令时发现找不到JAVA\_HOME目录。但是我是有安装JAVA\_HOME的，然后在脚本/opt/cloudera/cm/bin/cm-server中发现它默认使用的是/usr/java 这个目录下的jdk！

1.  启动agent节点

systemctl start cloudera-scm-agent
    systemctl start cloudera-scm-agent
    systemctl start cloudera-scm-agent

至此cm安装完成，使用  
http://\[server-host\]:7180/cmf/login  
账号：admin  
密码：admin  
进行访问！

# 五、安装CDH集群 #

## 5.1 接受条款和协议 ##

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5NjU3OTA5_size_16_color_FFFFFF_t_70 1]

# 七、其他配置与安装 #

## 7.1 修改HDFS的权限检查配置 ##

关闭HDFS中的权限检查：dfs.permissions.不勾选，不进行权限检查。线上不合适，后期会进行权限专门的处理  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5NjU3OTA5_size_16_color_FFFFFF_t_70 22]

## 7.2 配置NameNode HA ##
