    准备

    • 建议最少4台物理机或者虚拟机(一个控制节点,3个数据节点),4核16G,硬盘500G,挂载根目录
    • 如果用于学习,可以4核8G,如果是生产部署,推荐8核32G以上
    • 系统为CentOS7.6,使用root用户登录
    • CDH版本为5.13.1

    配置hosts(所有节点)

    假设4个节点IP为:

    10.88.36.200
    10.88.36.201
    10.88.36.202   
    10.88.36.203
    

    其中:

    • 10.88.36.200作为控制节点
    • 10.88.36.201-10.88.36.203作为数据节点

    在所有节点的/etc/hosts中添加:

    10.88.36.200 cdh1
    10.88.36.201 cdh2
    10.88.36.202 cdh3
    10.88.36.203 cdh4
    

    修改hostname(所有节点)

    分别登录各个节点,修改hostname为cdh1,cdh2,cdh3,cdh4:

    hostnamectl set-hostname YOUR_HOST_NAME
    

    开启ssh免登录(cdh1)

    在cdh1节点上执行:

    ssh-keygen -t rsa -b 2048
    

    一路回车,并拷贝至所有节点:

    ssh-copy-id cdh1
    ssh-copy-id cdh2
    ssh-copy-id cdh3
    ssh-copy-id cdh4
    

    关闭防火墙(所有节点)

    在所有节点上执行:

    systemctl stop firewalld
    systemctl disable firewalld
    

    安装jdk8(所有节点)

    在所有节点上执行:

    yum install java-1.8.0-openjdk -y
    

    安装mysql(cdh1)

    在cdh1节点上安装mysql5.7,建议从官网下载rpm包安装

    配置mysql(cdh1)

    修改/etc/my.cnf,在末尾添加:

    default-storage-engine=INNODB
    character-set-server=utf8
    collation-server=utf8_general_ci
    

    然后重启mysql:

    systemctl restart mysqld
    

    修改mysql密码及权限(cdh1)

    在cdh1上,获取mysql临时密码:

    cat /var/log/mysqld.log | grep -i password
    

    登录mysql,卸载validate_password插件:

    SET PASSWORD = PASSWORD('C@p19U#qfo');
    UNINSTALL PLUGIN validate_password;
    

    修改密码及权限:

    grant all privileges on *.* to 'root'@'%'  identified by 'C@p19U#qfo';
    

    安装mysql驱动(所有节点)

    在官网上下载mysql-connector-java-5.1.47.tar.gz,解压出 mysql-connector-java-5.1.47.jar
    执行:

    mkdir -p /usr/share/java
    cp mysql-connector-java-5.1.47.jar /usr/share/java/mysql-connector-java.jar
    

    下载cloudera资源:

    cloudera manager & agent:

    http://archive.cloudera.com/cm5/cm/5/cloudera-manager-centos7-cm5.13.1_x86_64.tar.gz

    parcel:

    http://archive.cloudera.com/cdh5/parcels/5.13.1/CDH-5.13.1-1.cdh5.13.1.p0.2-el7.parce
    http://archive.cloudera.com/cdh5/parcels/5.13.1/CDH-5.13.1-1.cdh5.13.1.p0.2-el7.parcel.sha1
    http://archive.cloudera.com/cdh5/parcels/5.13.1/manifest.json

    安装cloudera manager(cdh1节点)

    解压cloudera-manager-centos7-cm5.13.1_x86_64.tar.gz

    tar -zxvf cloudera-manager-centos7-cm5.13.1_x86_64.tar.gz -C /opt
    

    修改agent配置,将host_server修改为master

    vim /opt/cm-5.13.1/etc/cloudera-scm-agent/config.ini
    

    新建 cloudera-scm用户:

    useradd --system --home-dir /opt/cm-5.13.1/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
    

    初始化数据库:

    /opt/cm-5.13.1/share/cmf/schema/scm_prepare_database.sh mysql cm -hlocalhost -uroot -p'C@p19U#qfo' --scm-host localhost scm root 'C@p19U#qfo'
    

    初始化parcel(cdh1)

    mkdir -p /opt/cloudera/parcel-repo
    mv CDH-5.13.1-1.cdh5.13.1.p0.2-el7.parcel /opt/cloudera/parcel-repo
    mv CDH-5.13.1-1.cdh5.13.1.p0.2-el7.parcel.sha.1 /opt/cloudera/parcel-repo/CDH-5.13.1-1.cdh5.13.1.p0.2-el7.parcel.sha
    mv manifest.json /opt/cloudera/parcel-repo
    

    启动cloudera manager(cdh1)

    /opt/cm-5.13.1/etc/init.d/cloudera-scm-server start
    

    安装agent(所有数据节点)

    将master节点的/opt/cm-5.13.1目录拷贝至所有控制节点的/opt目录下

    scp -r /opt/cm-5.13.1 root@cdh2:/opt
    scp -r /opt/cm-5.13.1 root@cdh3:/opt
    scp -r /opt/cm-5.13.1 root@cdh4:/opt
    

    在所有数据节点,新建 cloudera-scm用户:

    useradd --system --home-dir /opt/cm-5.13.1/run/cloudera-scm-agent --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm
    

    启动cloudera agent(所有数据节点)

    /opt/cm-5.13.1/etc/init.d/cloudera-scm-agent start
    

    安装cloudera

    打开浏览器,访问10.88.36.200:7180(启动比较慢,需要1-2分钟)
    默认用户名/密码: admin/admin
    按照步骤安装即可(建议选择社区版安装)

    问题

    如果zookeeper安装错误,提示权限问题或找不到version-2目录,在zookeeper节点上执行:

    mkdir -p /var/lib/zookeeper/version-2
    chown  -R zookeeper:zookeeper /var/lib/zookeeper 
    chmod -R 755 /var/lib/zookeeper
    

    如果其他组件安装错误(如yarn),提示权限问题,在相关节点上执行:

    chown  -R hdfs:hdfs /var/lib/hadoop-hdfs
    chown  -R httpfs:httpfs /var/lib/hadoop-httpfs
    chown  -R kms:kms /var/lib/hadoop-kms
    chown  -R mapred:mapred /var/lib/hadoop-mapreduce
    chown  -R yarn:yarn /var/lib/hadoop-yarn
    chmod -R 755 /var/lib/hadoop-*
