Clouder Manager安装时出现please remove the following file: /etc/cloudera-scm-server/db.properties问题解决(图文详解)

说在前面的话

  我的机器是总共4台,分别为ubuntucmbigdata1、ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4。(注意啦,以下是针对Ubuntu系统的)

  在ubuntucmbigdata1上执行了

sudo apt-get install cloudera-manager-daemons  cloudera-manager-server 


sudo apt-get install cloudera-manager-daemons  cloudera-manager-agent 

  即,ubuntucmbigdata1是既做server,又做agent。

 

 

  在ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4上执行了

sudo apt-get install cloudera-manager-daemons  cloudera-manager-agent 

  即,ubuntucmbigdata2、3、和4是只做agent。

 

 

  在ubuntucmbigdata1、ubuntucmbigdata2、ubuntucmbigdata3、ubuntucmbigdata4上

新建文件sudo vi /etc/apt/sources.list.d/cloudera-manager.list,复制以下内容到cloudera.list里

# Packages for Cloudera Manager, Version 5, on Ubuntu 14.04 x86_64
deb [arch=amd64] http://archive.cloudera.com/cm5/ubuntu/trusty/amd64/cm trusty-cm5 contrib
deb-src http://archive.cloudera.com/cm5/ubuntu/trusty/amd64/cm trusty-cm5 contrib

 

  并且在在ubuntucmbigdata1、ubuntucmbigdata2、ubuntucmbigdata3、ubuntucmbigdata4上

  向apt添加cloudera源公钥,在所有节点执行如下命令:

curl -s http://archive.cloudera.com/cm5/ubuntu/trusty/amd64/cm/archive.key | sudo apt-key add -然后,再sudo apt-get update

解决办法

  思路1:

  思路2:

 

   查看cloudera-scm-agent的运行日志

  当cloudera-scm-server、cloudera-scm-agent start启动成功之后,可通过http://主节点IP:7180来访问CM,用户名密码都为admin。剩下的就是一直点下一步和根据具体的需求来配置集群了。

 

 

 注意,在此之前。

 

   注意,在此之前。

  ubuntucmbigdata1机器上,则需要执行

bigdata@ubuntucmbigdata1:~$ sudo /usr/share/cmf/schema/scm_prepare_database.sh mysql scm scm scm_password

[sudo] password for bigdata: 
Sorry, try again.
[sudo] password for bigdata:

bigdata@ubuntucmbigdata1:~$ sudo service cloudera-scm-server start

bigdata@ubuntucmbigdata1:~$ sudo service cloudera-scm-agent start
[sudo] password for bigdata: 
Starting cloudera-scm-agent: * cloudera-scm-agent started

bigdata@ubuntucmbigdata1:~$

 

 

 

 

 

 

  然后,在ubuntucmbigdata2、ubuntucmbigdata3、ubuntucmbigdata4上


bigdata@ubuntucmbigdata2:~$ sudo service cloudera-scm-agent start
[sudo] password for bigdata: 
Starting cloudera-scm-agent: * cloudera-scm-agent started


bigdata@ubuntucmbigdata2:~$


bigdata@ubuntucmbigdata3:~$ sudo service cloudera-scm-agent start
[sudo] password for bigdata: 
Starting cloudera-scm-agent: * cloudera-scm-agent started


bigdata@ubuntucmbigdata3:~$

 


bigdata@ubuntucmbigdata4:~$ sudo service cloudera-scm-agent start
[sudo] password for bigdata: 
Starting cloudera-scm-agent: * cloudera-scm-agent started


bigdata@ubuntucmbigdata4:~$

 

 

 

  思路3:

  关闭这台机器的防火墙

bigdata@ubuntucmbigdata1:/opt$ sudo ufw disable
Firewall stopped and disabled on system startup
bigdata@ubuntucmbigdata1:/opt$ sudo ufw status
Status: inactive
bigdata@ubuntucmbigdata1:/opt$ 

 

 

 

  思路4:

bigdata@ubuntucmbigdata1:/opt/cm-5.6.0/etc$ netstat -nltp
(No info could be read for "-p": geteuid()=1000 but you should be root.)

    思路5:

cloudera-scm-server启动时出现Caused by: javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Could not open connection问题解决方法(图文详解)

 

 

 

    思路6:

    时间同步

ntpdate pool.ntp.org  一般前面的6种思路是一定可以解决cloudera manager的7180 web界面访问不了

 

 

  思路7:(万不得已)

  最戳的办法,就是

http://www.aboutyun.com/thread-8992-1-1.html (包含centos、ubuntu、debian和rehat各版本都有)

  卸载它,重新来过。

正用得上,刚安装好的CDH5的CM server启不来,只好全部四节点卸载来过。


    

  如在ubuntu系统下

bigdata@ubuntucmbigdata1:/opt/softwares/cm-5.6.0$ sudo rm -Rf /usr/share/cmf /var/lib/cloudera* /var/cache/yum/cloudera*
bigdata@ubuntucmbigdata1:/opt/softwares/cm-5.6.0$ sudo apt-get purge 'cloudera-manager-*'
bigdata@ubuntucmbigdata1:/opt/softwares/cm-5.6.0$ sudo apt-get purge 'cloudera-manager-*' avro-tools crunch flume-ng hadoop-hdfs-fuse hadoop-hdfs-nfs3 hadoop-httpfs hbase-solr hive-hbase hive-webhcat hue-beeswax hue-hbase hue-impala hue-pig hue-plugins hue-rdbms hue-search hue-spark hue-sqoop hue-zookeeper impala impala-shell kite llama mahout oozie pig pig-udf-datafu search sentry solr-mapreduce spark-python sqoop sqoop2 whirrbigdata@ubuntucmbigdata1:/opt/softwares/cm-5.6.0$ sudo apt-get cleanbigdata@ubuntucmbigdata1:/opt/softwares/cm-5.6.0$ sudo rm -Rf /usr/share/cmf /var/lib/cloudera* /var/cache/yum/cloudera* /var/log/cloudera* /var/run/cloudera*bigdata@ubuntucmbigdata1:/opt/softwares/cm-5.6.0$ sudo rm -Rf /var/cache/apt/archives/cloudera*

 

 

  再进一步卸载彻底干净

  见

Cloudera Manager卸载笔记

 

 

1、通过管理平台分别停止组件服务和Cloudera Management Service

2、通过管理平台注销并移除Parcles (在控制台注销并移除,无论是安装的Parcles还是未安装的Parcles)

3、停止后台服务

  sudo service cloudera-scm-agent stop

      sudo service cloudera-scm-server stop    

  sudo service cloudera-scm-server-db stop

      sudo service mysqld stop

4、卸载Cloudera Manager Server

    执行命令:sudo /usr/share/cmf/uninstall-cloudera-manager.sh

5、清理配置和缓存信息

     在所有agent上执行:sudo umount -v /var/run/cloudera-scm-agent/process

     在所有主机上执行:sudo rm -rf /usr/share/cmf;

                              sudo rm -rf /var/lib/cloudera*;

            sudo rm -rf  /var/cache/yum/x86_64/6/cloudera*;

            sudo rm -rf  /var/log/cloudera*;

            sudo rm -rf  /var/run/cloudera*  /etc/cloudera* 

6、卸载rpm安装包

  1)查看 rpm -qa | grep cloudera

    2)卸载 for f in `rpm -qa | grep cloudera `  ; do sudo rpm -e ${f} ; done

7、清理安装文件

  sudo rm -rf /var/lib/hadoop-* /var/lib/impala /var/lib/solr /var/lib/zookeeper /var/lib/hue /var/lib/oozie  /var/lib/pgsql  /var/lib/sqoop2  /data/dfs/  /data/impala/ /data/yarn/  /dfs/ /impala/ /yarn/  /var/run/hadoop-*/ /var/run/hdfs-*/ /usr/bin/hadoop* /usr/bin/zookeeper* /usr/bin/hbase* /usr/bin/hive* /usr/bin/hdfs /usr/bin/mapred /usr/bin/yarn /usr/bin/sqoop* /usr/bin/oozie /etc/hadoop* /etc/zookeeper* /etc/hive* /etc/hue /etc/impala /etc/sqoop* /etc/oozie /etc/hbase* /etc/hcatalog 

     略过其它软件,只删除hadoop相关

  sudo rm -rf ` find /var/lib/alternatives/* ! -name "mta" ! -name "print" ! -name "zlibrary-ui"  -mtime -3` 

8、如果有hadoop先关进程还在,则杀死

     for u in hdfs mapred cloudera-scm hbase hue zookeeper oozie hive impala flume; do sudo kill $(ps -u $u -o pid=); done

9、清理parcel

    sudo rm -rf /opt/cloudera/parcel-cache /opt/cloudera/parcels

10、清理组件用户

     sudo userdel hue;sudo userdel impala;sudo userdel spark;sudo userdel sentry;sudo userdel sqoop2;sudo userdel hbase;sudo userdel oozie;sudo userdel yarn;sudo userdel mapred;sudo userdel zookeeper;sudo userdel httpfs;sudo userdel solr;sudo userdel kms;sudo userdel hive;sudo userdel flume;sudo userdel hdfs;sudo userdel sqoop;sudo userdel llama;sudo userdel cloudera-scm;sudo userdel postgres;

                              

 

 

 

 

 

  然后,就可以继续了。(这是针对bin方式来安装)

  也许,你在卸载中,会遇到如下问题
