CDH在线安装详细步骤(使用官方yum源)

在线安装过程不算太过复杂, 需要细心

假如我想安装5.7.0, 需要做如下 *** 作

打开一下两个网址查找是否有5.7.0文件夹, 如果有, 才能安装5.7.0版本, 否则, 选择其他版本

需禅租饥要在各失败的型磨agent机器上执行 mv /usr/bin/host /usr/bin/host.bak

楼主由于安装时没有修改yum源, 只是cdh版本太高, 和应用不兼容, 所以需要卸载cdh并安装低贺返版本5.7.0

卸载步骤:

参考博客: https://blog.csdn.net/wh211212/article/details/78743191

1、yum install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server

2、cd /opt/cloudera/parcel-repo

（1）将第一部分下载的CDH Parcel文件（CDH-6.2.0-1.cdh6.2.0.p0.967373-el7.parcelCDH-6.2.0-1.cdh6.2.0.p0.967373-el7.parcel.sha256和manifest.json）上传至该目录下

（2）mv CDH-6.2.0-1.cdh6.2.0.p0.967373-el7.parcel.sha256 CDH-6.2.0-1.cdh6.2.0.p0.967373-el7.parcel.sha

（3）chown -R cloudera-scm:cloudera-scm /opt/cloudera/parcel-repo/*

3、将mysql-connector-java-5.1.47-bin.jar文件上传至CM Server节点上的/usr/share/java/目录下并重命名为mysql-connector-java.jar

4、安裂拍高装 mysql（安装过程略），并创建相应库

mysql>CREATE DATABASE scm DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci

mysql>CREATE DATABASE amon DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci

mysql>CREATE DATABASE rman DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci

mysql>CREATE DATABASE metastore DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci

mysql>GRANT ALL ON scm.* TO 'scm'肆尺@'%' IDENTIFIED BY 'scm'

mysql>GRANT ALL ON amon.* TO 'amon'@'%' IDENTIFIED BY 'amon'

mysql>GRANT ALL ON rman.* TO 'rman'@'%' IDENTIFIED BY 'rman'

mysql>GRANT ALL ON metastore.* TO 'hive'@'%' IDENTIFIED BY 'hive'

mysql>FLUSH PRIVILEGES

mysql数据库与CM Server是同一台主机

执行命令贺蔽：/opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm

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 -h --scm-host scm scm

5、启动cloudera-scm-server

systemctl start cloudera-scm-server

6、登录页面进行配置

ip:7180
