[安装指南：https://docs.cloudera.com/documentation/enterprise/5-12-x/topics/installation.html][https_docs.cloudera.com_documentation_enterprise_5-12-x_topics_installation.html]

*  ***问题1：解决root用户在hdfs中permission denied问题***

\- 方法1： 修改hdfs配置中的supergroup超级组 (默认值为supergroup, 改为root,重启配置就行)

\- 方法2： 修改hdfs配置中的System User： root (不推荐）

cloudera安装hdfs后，默认的配置System User是hdfs, 修改root用户，重启会报错：/var/run/hdfs-sockets权限问题（由于是旧的用户占用了socket,所以删除就行）

#java.io.IOException: the path component: '/var/run/hdfs-sockets' is owned by a user who is not root and not you.
    #Your effective user id is 0; the path is owned by user id 496, and its permissions are 0755.  Please fix this or select a different socket path
    
    #解决：
    rm -rf  /var/run/hdfs-sockets/

*  ***问题2：修改hdfs系统用户System User为普通用户: wang***

chown -R wang /dfs
    chown -R wang /var/log/hadoop-hdfs
    chown -R wang /var/run/hdfs-sockets

*  ***问题3：修改主机名：确认主机名没有 \_ (下划线)***

主机名不合法，存在_时，agent启动后一会又stop了，日志打印为：
    Re-using pre-existing directory: /var/run/cloudera-scm-agent

**脚本化快速安装cdh集群，参考另一篇博客**：[https://blog.csdn.net/eyeofeagle/article/details/98667232][https_blog.csdn.net_eyeofeagle_article_details_98667232]

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

要点：

1.  工具的特点
2.  具体操作

1，什么是CM?   (Cloudera Manager)

下载地址： [http://archive.cloudera.com/cm5/cm/5/][http_archive.cloudera.com_cm5_cm_5]

Cloudera Manager则是为了便于在集群中进行Hadoop等大数据处理相关的服务安装和监控管理的组件，对集群中主机、Hadoop、Hive、Spark等服务的安装配置管理做了极大简化。

CDH (Cloudera's Distribution, including Apache Hadoop)，是Hadoop众多分支中的一种，由Cloudera维护，基于稳定版本的Apache Hadoop构建，并集成了很多补丁，可直接用于生产环境。

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

2， 如何使用CM来安装CDH ?

下载地址： [http://archive.cloudera.com/cdh5/parcels][http_archive.cloudera.com_cdh5_parcels]

(安装包版本需要和系统的版本对应， 此处使用集群： centos7  × 3 【一个namenode, 两个datenode】 )

1.  准备CM安装包:  cloudera-manager-centos7-cm5.13.0\_x86\_64.tar.gz, 
2.  CDH安装包:  CDH-5.13.0-1.cdh5.13.0.p0.29-el7.parcel，  CDH-5.13.0-1.cdh5.13.0.p0.29-el7.parcel.sha1

cloudera-manager的tar包，解压目录为： （红色部分为不存在的， 需要手动创建）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2V5ZW9mZWFnbGU_size_16_color_FFFFFF_t_70][]

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

3， 具体安装步骤： 先安装CM,  启动server + agent--->进入网页：namenode:7180

*  安装mysql:  \[上一篇博客： [https://blog.csdn.net/eyeofeagle/article/details/85010957][https_blog.csdn.net_eyeofeagle_article_details_85010957]\]
 *  配置cdh :   root用户登陆 在/root目录下准备文件【cm, cdh】
 *  #  a, 启动server服务 #

    # 修改提供服务的server ip
    tar -zxvf ~/cloudera-manager*.tar.gz  -C /opt/
    cp ~/CDH*.parcel* /opt/cloudera/parcel-repo/
    cp ~/manifest.json /opt/cloudera/parcel-repo/
    #sed -i s@server_host=localhost@server_host=s101@g    /opt/cm*/etc/cloudera-scm-agent/config.ini
     
     
    #1,  准备jdk

    [ ! $existsJdk ] &&  mkdir /usr/java ;\
    tar -zxvf *jdk*.gz -C /usr/java/ && cd /usr/java/; ln -sfT *jdk* jdk; \

    export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
    EOF
    source /etc/profile
    
    
    2,  创建cloudera-scm用户: (在所有节点, 包括agent, server )
    userdel cloudera-scm
    cd /opt/cm*
    useradd --system --home=`pwd`/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
     
    #3, 配置mysql 元数据信息： cloudera-manager使用mysql保存hive, oozie等的元数据
    #修改mysql密码： mysqladmin -u root password '123456'
    [ ! -d /usr/share/java ] &&  mkdir /usr/share/java -p
    cp ~/mysql-connector-*.jar /usr/share/java/mysql-connector-java.jar
    cp ~/mysql-connector-*.jar  /opt/cm*/share/cmf/lib
    mysql -uroot -p123456 -e "drop database if exists hive ; create database hive default charset utf8";
    mysql -uroot -p123456 -e "drop database if exists zookeeper ; create database zookeeper default charset utf8";
    mysql -uroot -p123456 -e "drop database if exists oozie; create database oozie default charset utf8";
    mysql -uroot -p123456 -e "drop database if exists hue; create database hue default charset utf8";
    mysql -uroot -p123456 -e "drop database if exists scm";
    
    #mysql -uroot -p12345 --scm-host [cm server的主机名] [cm的数据库]   [cm数据库访问用户] [cm数据库访问用户的密码]
    /opt/cm*/share/cmf/schema/scm_prepare_database.sh mysql  -uroot -p123456  scm scm scm
    #或者直接编辑/opt/cm*/etc/cloudera-scm-server/db.properties, 配置mysql连接的参数
    #如果要修改mysql端口：　com.cloudera.cmf.db.host=localhost:3308
    
    mysql -uroot -p123456 -e "grant all privileges on *.* to 'scm'@'%' identified by 'scm' with grant option; flush privileges;";
    mysql -uroot -p123456 -e "grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option; flush privileges;";
     
     
    #4, 更改/opt目录为此用户所属
    chown -R cloudera-scm:cloudera-scm /opt/{cloudera,cm*}
    [ ! -d /var/lib/cloudera-scm-server ] && mkdir /var/lib/cloudera-scm-server
    chown -R cloudera-scm:cloudera-scm /var/lib/cloudera-scm-server
     
    #5，启动server
    /opt/cm*/etc/init.d/cloudera-scm-server start
    tail -F /opt/cm*/log/cloudera-scm-server/cloudera-scm-server.log 
     
     #启动agent
    [ ! -d /opt/cloudera/parcels ]  && mkdir  /opt/cloudera/parcels -p 
    [ ! -d /opt/cloudera/csd ]  	&& mkdir  /opt/cloudera/csd -p 
    chown -R cloudera-scm:cloudera-scm /opt/
    /opt/cm*/etc/init.d/cloudera-scm-agent start
    tail -F /opt/cm*/log/cloudera-scm-agent/cloudera-scm-agent.log

*  # b, 启动agent 服务 #

tar -zxvf ~/cloudera-manager*.tar.gz -C /opt
    sed -i s@server_host=localhost@server_host=s222@g    /opt/cm*/etc/cloudera-scm-agent/config.ini
    mkdir  /opt/cloudera/parcels -p 
     
    #创建用户
    userdel cloudera-scm
    cd /opt/cm*
    useradd --system --home=`pwd`/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
    chown -R cloudera-scm:cloudera-scm /opt/
     
    # 启动agent
    /opt/cm-*/etc/init.d/cloudera-scm-agent start
    tail -F /opt/cm*/log/cloudera-scm-agent/cloudera-scm-agent.log

*  # 3, 安装hive, sqoop #

#安装hive的机器
    sudo cp mysql-connector-java-5.1.27.jar /opt/cloudera/parcels/CDH-5.12.0-1.cdh5.12.0.p0.29/lib/hive/lib/
    sudo cp mysql-connector-java-5.1.27.jar  /usr/share/java/mysql-connector-java.jar
    
    #安装sqoop的机器
    sudo cp mysql-connector-java-5.1.27.jar /opt/cloudera/parcels/CDH-5.12.0-1.cdh5.12.0.p0.29/lib/sqoop/lib/
    sudo cp mysql-connector-java-5.1.27.jar  /usr/share/java/mysql-connector-java.jar

*  # 4, 安装kafka #

下载kafka的parcel文件： http://archive.cloudera.com/kafka/parcels/latest/，放在/opt/cloudera/parcel-repo下
    下载kafka jar包,下载地址：http://archive.cloudera.com/csds/kafka/, 放在/opt/cloudera/csd下
    
    kafka启动报错： 在报错中有outofMemory的提示==> 解决： 在cdh:7180界面搜索kafka配置的memory选项，修改 Java Heap Size of Broker为1G
    
    kafka生产者发送消息报错： kafka-console-producer --broker-list localhost:9092 --topic t1
     ERROR Error when sending message to topic t1 with key: null, value: 2 bytes with error: Failed to update metadata after 60000 ms. (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)
    =======》解决： 输入的zookeeper或broker的地址localhost解析为127.0.0.1找不到对应的zk服务，所以修改为正确的主机名

*  # 5，安装hue #

## 大数据parel组件：安装异常处理 ##

1 ，安装hdfs， datanode启动不了

查看datanode启动日志： 默认路径/var/log/hadoop-hdfs/hadoop-cmf-hdfs-DATANODE-s101.log.out
