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'@'%' 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:/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
你需要先使用mysql链接mysqld(第一步开启的服务端),之后手动创建blog_db数据库,rails是不会自动创建mysql的数据库的(里面的各个表你不需要创建,这是active_record的工作)。看你error
log应该是mysqld没运行!
