Cloudera Manager + CDH安装

作者: 忘净空 | 来源:发表于2017-05-11 21:21 被阅读560次

    鉴于apache版本的Hadoop监控不完善,我们生产使用了CDH,同时使用Cloudera Manager监控,Cloudera Manager不但能监控集群还能监控机器,免费版也够用真心值得推荐。

    离线安装Cloudera Manager和CDH

    楼主自测很靠谱:最靠谱的CDH5安装指南

    备注:通过修改每个主机/etc/cloudera-scm-agent/config.ini的server_host为安装Cloudera Manager的机器的主机名来直接识别需要管理的主机,这样你可以避免为CDH集群按照指定主机。

    Cloudera Manager配置MySQL

    1. 安装MySQL(忽略)

    2. 创建cm用户赋予权限(为了避免问题赋予最大权限)
      create user 'cm' identified by 'cm';
      grant all on . to 'cm'@'master01' identified by 'cm' with grant option;
      flush privileges;

    3. 初始化Cloudera Manager的数据库
      /usr/share/cmf/schema/scm_prepare_database.sh -h master01 -ucm -pcm mysql --scm-host master01 scm cm cm

      执行完命令后查看/etc/cloudera-scm-server/db.properties如下

      com.cloudera.cmf.db.type=mysql
      com.cloudera.cmf.db.host=master01
      com.cloudera.cmf.db.name=scm
      com.cloudera.cmf.db.user=cm
      com.cloudera.cmf.db.password=cm
      
    4. 关闭内置数据库PostgreSQL(一定要停止)
      /etc/init.d/cloudera-scm-server-db stop

    5. 重启Cloudera Manager
      /etc/init.d/cloudera-scm-server stop
      /etc/init.d/cloudera-scm-server start

    配置时钟同步(使用NTP)

    假设现在有3个节点(hadoop01、hadoop02、hadoop03):
    hadoop01节点作为ntp服务器与外界对时中心同步时间,随后对hadoop02、hadoop03节点提供时间同步服务。
    hadoop02、hadoop03节点以hadoop01节点为基础同步时间。
    
    1. 每个节点安装ntp
      yum install ntp

    2. 配置hadoop01的/etc/ntp.conf

       server 0.cn.pool.ntp.org
       server 0.asia.pool.ntp.org
       server 3.asia.pool.ntp.org
      
       # allow update time by the upper server
       # 允许上层时间服务器主动修改本机时间
       restrict 0.cn.pool.ntp.org nomodify notrap noquery
       restrict 0.asia.pool.ntp.org nomodify notrap noquery
       restrict 3.asia.pool.ntp.org nomodify notrap noquery
      
       # Undisciplined Local Clock. This is a fake driver intended for backup
       # and when no outside source of synchronized time is available.
       # 外部时间服务器不可用时,以本地时间作为时间服务
       server  127.127.1.0     # local clock
       fudge   127.127.1.0 stratum 10
      
    3. 配置hadoop02、hdaoop03的/etc/ntp.conf

      server 0.cn.pool.ntp.org
      server 0.asia.pool.ntp.org
      server 3.asia.pool.ntp.org
      
      # allow update time by the upper server
      # 允许上层时间服务器主动修改本机时间
      restrict 0.cn.pool.ntp.org nomodify notrap noquery
      restrict 0.asia.pool.ntp.org nomodify notrap noquery
      restrict 3.asia.pool.ntp.org nomodify notrap noquery
      
      # Undisciplined Local Clock. This is a fake driver intended for backup
      # and when no outside source of synchronized time is available.
      # 外部时间服务器不可用时,以本地时间作为时间服务
      server  127.127.1.0     # local clock
      fudge   127.127.1.0 stratum 10
      server hadoop01  prefer
      
    4. 启动 ntp
      hadoop01 启动之前先手动同步下ntpdate 0.cn.pool.ntp.org
      hadoop02-03 启动之前先手动同步下ntpdate hadoop01

      service ntpd start

    5. 设置开机启动(每个节点)
      chkconfig ntpd on

    安装CDH中遇到的问题

    Cloudera Manager安装无法登陆

    Cloudera Manager安装后访问问题
    备注:问题没有彻底解决,通过远程访问阿里windows系统

    Hive问题

    通过CM启动hive报错

    Hive出现的问题作者的文章中都有,我居然其中的问题全出现了。
    mysql-connector-java.jar 位置在:/usr/share/java/mysql-connector-java.jar
    且名字一定要为:mysql-connector-java.jar

    配置HA

    官网配置

    Hive

    Hive HA

    完全卸载Cloudera Manager

    卸载Cloudera Manager

    配置ngxin访问CM

    问题

    Cloudera_Server启动: com.cloudera.server.web.cmf.csrf.CsrfRefererInterceptor: Rejecting request originating from

    解决

    grep安装目录的csrf,直接注释掉然后重启cloudera-manager-server

    [root@xx.xx.xx.xx cloudera-scm-server]# cd /usr/share/cmf/
    [root@xx.xx.xx.xx cmf]# grep -i -r  csrf  ./
    Binary file ./cloudera-navigator-server/libs/cdh5/hadoop-yarn-server-nodemanager-2.6.0-cdh5.5.0.jar matches
    Binary file ./common_jars/hadoop-yarn-server-nodemanager-2.6.0-cdh5.5.0.jar matches
    Binary file ./common_jars/server-5.6.0.jar matches
    Binary file ./common_jars/hadoop-yarn-server-resourcemanager-2.5.0-cdh5.3.2.jar matches
    ./webapp/WEB-INF/spring/mvc-config.xml:                <bean class="com.cloudera.server.web.cmf.csrf.CsrfRefererInterceptor" />
    Binary file ./lib/cdh5-java6/hadoop-yarn-server-resourcemanager-2.5.0-cdh5.3.2.jar matches
    Binary file ./lib/server-5.6.0.jar matches
    Binary file ./lib/cdh5/hadoop-yarn-server-nodemanager-2.6.0-cdh5.5.0.jar matches
    [root@xx.xx.xx.xx cmf]# vi ./webapp/WEB-INF/spring/mvc-config.xml
    注释掉这个bean,然后重启server,在访问nginx,整个世界清净了
    <!--  <bean class="com.cloudera.server.web.cmf.csrf.CsrfRefererInterceptor" /> -->
