Cloudera CDH 6.3.2 Centos7离线安装

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。
CDH的优点：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CDH6.3.2。
安装前置需求:hosts,hostname,防火墙关闭,selinux关闭,ssh免密登录,自带的mariadb卸载,NTP时间同步,swap关闭,jdk安装,透明页禁用

将CDH 离线包CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel放入/opt/cloudera/parcel-repo
在/opt/cloudera/parcel-repo目录生成sha1签名文件

sha1sum CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel | awk '{ print $1 }' > CDH-6.3.2-1.cdh6.3.2.p0.1605554-el7.parcel.sha

[/collapse]

可以通过systemctl start cloudera-scm-server和systemctl enable cloudera-scm-agent启动服务

CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel.sha1修改为CDH-6.3.1-1.cdh6.3.1.p0.1470567-el7.parcel.sha放入/opt/cloudera/parcel-repo

可以通过tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log观看日志，当看到Started Jetty server.时表示服务已经启动成功了,访问对应IP+7180端口即可
