 *  3

### 3、 修改transparent\_hugepage参数(透明大页面压缩) ###

echo never > /sys/kernel/mm/transparent_hugepage/defrag
    echo never > /sys/kernel/mm/transparent_hugepage/enabled
    echo 'echo never > /sys/kernel/mm/transparent_hugepage/defrag' >> /etc/rc.d/rc.local
    echo 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' >> /etc/rc.d/rc.local

*  1

    sudo yum upgrade cloudera-manager-daemons cloudera-manager-agent
    rpm -qa 'cloudera-manager-*'

*  1
 *  2
 *  3

### 5、初始化数据库 ###

mysql -uroot -p

*  1

# Cloudera Manager的数据库
    CREATE DATABASE scm DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    GRANT ALL ON scm.* TO 'scm'@'%' IDENTIFIED BY 'scm@123';
    # Activity Monitor的数据库
    CREATE DATABASE amon DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

### 6、使用scm初始化mysql ###

sh /opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm

*  1

### 7、主节点启动server ###

systemctl start cloudera-scm-server
    systemctl enable cloudera-scm-server
    tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log
    systemctl status cloudera-scm-server

*  1
 *  2
 *  3
 *  4

### 8、子节点启动agent ###

配置server服务器地址

vim /etc/cloudera-scm-agent/config.ini

*  1

server_host=node001

*  1

启动agent服务

systemctl start cloudera-scm-agent
    systemctl enable cloudera-scm-agent
    tail -f /var/log/cloudera-scm-agent/cloudera-scm-agent.log
    systemctl status cloudera-scm-agent

*  1
 *  2
 *  3
 *  4

### 9、网页访问cm ###

http://39.101.192.109:7180/

## 四、异常解决方案 ##

### 1、SqlExceptionHelper - Table ‘scm.CM\_VERSION’ doesn’t exist ###

如果为linux系统，mysql修改为大小写不敏感，修改/etc/my.conf文件中 \[mysqld\] 的内容

lower_case_table_names=1

*  1

systemctl restart mysql

*  1

删除scm数据库，新建数据库，重新执行scm\_prepare\_database.sh

sh /opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm

*  1

### 2、cm-server\[38046\]: ERROR StatusLogger No log4j2 configuration file found. ###

看一下/var/log/cloudera-scm-server/cloudera-scm-server.log日志，可能为其他包中报了其他的异常，导致找不到log4j2的配置。例如找不到数据表，或者数据表数据为空等。

### 3、scm.hosts not exist 或者表无数据 ###

（1）如果为linux系统，mysql修改为大小写不敏感，删除scm数据库后，新建数据库，重新执行scm\_prepare\_database.sh  
（2）主机名冲突： [https://blog.csdn.net/NeverGiveup54/article/details/102836562][https_blog.csdn.net_NeverGiveup54_article_details_102836562]  
（3）未设置主机名，在hosts中未设置主机名与ip的映射关系

### 4、cm安装完成后，无法访问 ###

（1）如果是自建服务器，可以关闭防火墙，或者开放网络端口  
（2）如果是从阿里云或腾讯云购买的服务器，通过管理控制台开放网络端口

### 5、找不到哈希文件 ###

sha1文件重命名为sha，要保证这里的sha的哈希在mainfest.json中一致。  
在界面中修改“更多选项”中的列表，添加一个新的，然后再删除，相当于刷新一遍缓存。

### 6、找不到cloudera-repos/allkeys.asc ###

未下载这个文件，在网上下载这个文件后放到/var/www/html/cloudera-repos/目录

### 7、cdh离线安装无法复制文件 ###

sha256文件重命名为sha和sha1，要保证这里的sha的哈希在mainfest.json中一致。

### 8、主机运行状态不良 / Cluster not found ###

[https://blog.csdn.net/u011031430/article/details/74057601][https_blog.csdn.net_u011031430_article_details_74057601]  
在cm界面中，退回上一步

rm -f /opt/cloudera-manager/cm/lib/cloudera-scm-agent/cm_guid

*  1

或者

rm -f /var/lib/cloudera-scm-agent/cm_guid
    systemctl restart cloudera-scm-agent

*  1
 *  2

### 9、CDH HDFS：NameNode is not formatted. ###

未使用的集群使用：hadoop namenode -format  
已有数据的集群：[https://blog.csdn.net/weixin\_44202548/article/details/86496440][https_blog.csdn.net_weixin_44202548_article_details_86496440]

### 10、Starting cloudera-scm-server: \[FAILED\] ###

systemctl status -l cloudera-scm-server

*  1

查看具体的失败原因，如果未找到可以在日志文件中查看原因

vi /var/log/cloudera-scm-server/cloudera-scm-server.log

*  1

### 11、cloudera-scm-agent日志中有错误 ###

rm -f /opt/cloudera-manager/cm-5.11.1/lib/cloudera-scm-agent/cm_guid

*  1

或者

rm -f /var/lib/cloudera-scm-agent/cm_guid
    systemctl restart cloudera-scm-agent

*  1
 *  2

### 12、启动cloudera-scm-agent,cloudera-scm-server时，说JDK不支持，要使用oracle jdk ###

一般在安装前就会报这个错，如果你已经安装了oracle jdk，检查环境变量是否配置JAVA，或者删除系统中的openjdk，重新安装oracle jdk

### 13、无法发出查询：未能连接到Host Monitor ###

未初始化scm数据导致的，可能是由于在新建集群后，中断安装导致的  
解决办法为：在CM界面删除集群，停止cm服务，并在后台停止服务

systemctl stop cloudera-scm-agent
    systemctl stop cloudera-scm-server

*  1
 *  2

重新从 第三章的第6小结开始

### 14、Hive启动失败，报如下错误 ###

Command failed to run because this role has an invalid configuration. Review and correct its configuration. First error: Enable Stored Notifications in Database is required by Sentry and must be enabled.

*  1

需要在Sentry中设置hive\_enable\_db\_notification，这个选项打上勾。

### 15、Hive启动失败，报如下错误 ###

Command failed to run because server kudu has an invalid configuration. Review and correct its configuration. First error: Sentry authraizion in Kudu required that Hive is configured with Kudu.

*  1

重启Hive后，Resume。

### 16、全部安装好后，impala一直在重启，看日志显示： ###

Could not connect to meta store using any of the URIs provided. Most recent failure:.......Commection refused
    Failed to connect to the MetaStore Server...
    Failed to connect to Hive MetaStore. Retrying.

*  1
 *  2
 *  3

（1）重启Hive、MetaStore，通过命令行连接Hive，看是否正常  
（2）检查hive连接的数据库，数据库名可能为hive或者metastore，看里面是否有29张表，表中是否有数据  
（3）如果库中没有表或没有数据，则

### 17、用beeline连接hiveServer2时，报下面的错 ###

FAILED: InvalidConfigurationException hive.server2.authentication can’t be none in non-testing mode  
修改hive-site.xml中的testing.mode为true

<property>
      <name>sentry.hive.testing.mode</name>
      <value>true</value>
    </property>

*  1
 *  2
 *  3
 *  4

### 18、通过beeline连接hive后切换database，显示如下： ###

User Hive does not have privileges for SWITCHDATABASE

*  1

新建角色，赋权限给hive用户  
[https://blog.csdn.net/lvtula/article/details/89177670][https_blog.csdn.net_lvtula_article_details_89177670]

### 19、Sentry启动HA的时候，报错，后台提示com.mysql.jdbc.Driver找不到 ###

在HA的节点中，看一下/share/lib/有没有jdbc的jar包。如果没有，下载一个到该目录  
[https://dev.mysql.com/downloads/connector/j/5.1.html][https_dev.mysql.com_downloads_connector_j_5.1.html]

### 20、HDFS、YARN webui无法访问 ###

（1）如果域名绑定的是内网的IP，那这个WebUI默认绑定内网IP，可以在HDFS / YARN 配置中搜索“通配符”，把NameNode和DataNode使用通配符的选项勾选  
（2）搜索webui，关闭kerberos的配置
