• CDH6.3.2 集群搭建


    一.CDH简介
    官网:https://www.cloudera.com/
    CDH,全称Cloudera's Distribution, including Apache Hadoop。是Hadoop众多分支中对应中的一种,由Cloudera维护,基于稳定版本的Apache Hadoop构建,提供了Hadoop的核心(可扩展存储、分布式计算),最为重要的是提供基于web的用户界面。
    优点:版本划分清晰,更新速度快,支持Kerberos安全认证,支持多种安装方式(如Yum、rpm等)。CDH分为Cloudera Manager管理平台和CDH parcel(parcel包含各种组件的安装包)。这里采用CM6.3.1(2019-10-11)和CDH6.3.2(2019-11-12更新)。

    二.CDH三节点集群搭建环境配置准备
    1.四台台机器配置及ip,
    centos7.6 主节点 ip:192.168.37.101
    centos7.6 从节点 ip:192.168.37.102
    centos7.6 从节点 ip:192.168.37.103
    单独分一台机器部署mysql
    centos7.6 主节点 ip:192.168.37.107

    2.修改主机名
    hostnamectl set-hostname centos001
    hostnamectl set-hostname centos002
    hostnamectl set-hostname centos003
    hostnamectl set-hostname centos007

    3.关闭selinux,firewalld
    (1)不重启的关闭  # setenforce 0   #重启电脑后失效
    (2)重启电脑的关闭 # vi /etc/selinux/config
    把SELINUX=enforce 改成disabled就可以了,#重启电脑,永久生效
    systemctl stop firewalld 关闭防火墙
    systemctl disable firewalld 禁用防火墙开机自启

    4.三台主机添加hosts,好能相互解析
    echo -e "192.168.37.101 centos001 192.168.37.102 centos002 192.168.37.103 centos003 " >> /etc/hosts

    5.NTP时间同步

    NTP安装
    sudo yum -y install ntp
    sudo /etc/ntp.conf
    ## 加入时间服务器:
    server 0.asia.pool.ntp.org
    server 1.asia.pool.ntp.org
    server 2.asia.pool.ntp.org
    server 3.asia.pool.ntp.org
    PS: 或在https://www.pool.ntp.org/zone/asia找最适合的时间服务器
    systemctl start ntpd.service 启动NTP时间服务器
    systemctl enable ntpd.service 设置NTP开机自动启动
    systemctl status ntpd.service 查看NTP是否正常运行

    查看与时间同步服务器的时间偏差:ntpdc -c loopinfo
    查看当前同步的时间服务器:ntpq -p
    查看状态:ntpstat


    6.三台机器相互免密

    ssh-keygen && ssh-copy-id -i user@B
    每个节点上执行:
    ssh-keygen
    ssh-copy-id -i root@centos001
    ssh-copy-id -i root@centos002
    ssh-copy-id -i root@centos003

    7.安装JDK(所有节点)
    注意:CDH的安装 要求使用指定版本的oracle-j2sdk1.8
    查询是否有已经安装的jdk
    rpm -qa | grep java
    如果之前安装过Java组件,先将其卸载
    yum remove java* -y
    上传安装包 oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm 到/soft/download目录
    启动安装
    rpm -ivh oracle-j2sdk1.8-1.8.0+update181-1.x86_64.rpm
    查找jdk安装路径
    find / -name java
    配置环境变量
    echo 'export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera' >> /etc/profile
    echo 'export PATH=$PATH:$JAVA_HOME/bin' >> /etc/profile
    source /etc/profile
    验证java -version

    8.各节点安装mysql驱动
    下载jdbc依赖,上传JDBC依赖包(所有节点)
    mysql-connector-java-8.0.12.jar
    创建目录mkdir -p /usr/share/java
    上传mysql-connector-java-8.0.12.jar包
    重命名 mv mysql-connector-java-8.0.12.jar mysql-connector-java.jar

    三.安装CDH三节点集群
    1.主节点安装Apache Httpd服务
    安装启动
    yum install httpd -y
    systemctl start httpd
    systemctl enable httpd

    2.安装mysql
    可参考:https://www.cnblogs.com/pinghengxing/p/9402825.html

    3.创建数据库
    CREATE DATABASE scm DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE amon DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE rman DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE hue DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE metastore DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE sentry DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE nav DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE navms DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE oozie DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE hive DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
    CREATE DATABASE hbase DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

    CREATE DATABASE monitor DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;


    4.配置Cloudera Manager安装包yum源(master节点,此集群中为centos001,centos002和centos003要配置该源)
    创建目录(master节点)
    mkdir -p /var/www/html/cloudera-repos/cm6
    cdh6.3.2的下载地址:
    链接: https://pan.baidu.com/s/16Hw38qZfLGZzLsrtHDWwhg 提取码: w1h2 复制这段内容后打开百度网盘手机App,操作更方便哦
    --来自百度网盘超级会员v2的分享
    将下载好的rmp安装包上传到(其中CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel.sha1 需去掉最后的1)
    /var/www/html/cloudera-repos/cm6

    创建仓库(master节点)
    cd /var/www/html/cloudera-repos/cm6
    yum install -y createrepo
    createrepo .

    创建repo文件(所有节点)
    vi /etc/yum.repos.d/cloudera-manager.repo
    [cloudera-manager]
    name=Cloudera Manager 6.3.1
    baseurl=http://centos001/cloudera-repos/cm6
    #gpgkey=https://archive.cloudera.com/cm6/6.3.1/redhat7/yum/RPM-GPG-KEY-cloudera
    gpgcheck=0
    enabled=1
    #autorefresh=0
    #type=rpm-md

    清理并缓存(所有节点):更新yum源
    yum clean all
    yum makecache
    yum repolist

    5.安装 Cloudera Manager(master节点)
    执行安装
    yum install -y cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server
    安装完CM后/opt/ 下会出现cloudera目录


    6,执行CM初始化脚本
    mysql数据库与CM Server是同一台主机
    执行命令:/opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm root 123456

    mysql数据库与CM Server不在同一台主机上
    执行命令:
    /opt/cloudera/cm/schema/scm_prepare_database.sh mysql -h192.168.37.107 -P3306 scm root PHXwlj.19901022


    7.启动cm

    systemctl start cloudera-scm-server.service
    systemctl stop cloudera-scm-server.service
    systemctl status cloudera-scm-server.service
    systemctl enable cloudera-scm-server.service
    sudo tail -100f /var/log/cloudera-scm-server/cloudera-scm-server.log

    登陆
    http://192.168.37.101:7180
    admin/admin/

    8.手动安装cloudera-manager-agent,在两台从机上安装(也可以通过管理界面安装cloudera-manager-agent)
    yum install cloudera-manager-daemons cloudera-manager-agent -y
    yum install cloudera-manager-agent -y

    vi /etc/cloudera-scm-agent/config.ini
    # 将server_host修改为CM-Server所在的主机名
    server_host=centos001


    systemctl start cloudera-scm-agent
    systemctl status cloudera-scm-agent
    systemctl stop cloudera-scm-agent
    systemctl enable cloudera-scm-agent

    tail -100f /var/log/cloudera-scm-agent/cloudera-scm-agent.log
