7, CM and CDH installation preparations

1) Unzip the package to/opt
Tar zxvf cloudera-manager-centos7-cm5.5.0_x86_64.tar.gz-c/opt
2) Copy parcel package to/opt/cloudera/parcel-repo
sudo cp/usr/local/software/cdh-5.5.0-1.cdh5.5.0.p0.8-el7.parcel.sha1/opt/cloudera/parcel-repo/ Cdh-5.5.0-1.cdh5.5.0.p0.8-el7.parcel.sha

sudo cp/usr/local/software/manifest.json/opt/cloudera/parcel-repo

sudo cp/usr/local/software/cdh-5.5.0-1.cdh5.5.0.p0.8-el7.parcel/opt/cloudera/parcel-repo
3) Modify Server_host
Vi/opt/cm-5.5.0/etc/cloudera-scm-agent/config.ini
server_host=
4) Create user CLOUDERA-SCM
Useradd--system--home=/opt/cm-5.5.0/run/cloudera-scm-server--no-create-home--shell=/bin/false--comment " Cloudera SCM User "CLOUDERA-SCM
5) Cloudera Manager 5.5 Build Database
/opt/cm-5.5.0/share/cmf/schema/scm_prepare_database.sh MySQL cm-hlocalhost-uroot-p123456--scm-host localhost SCM SCM SCM

Need to copy the JDBC driver
cp/usr/local/software/mysql-connector-java-5.1.38-bin.jar/opt/cm-5.5.0/share/cmf/lib/

6) Create additional databases as needed
Data name take component header two letters or full names such as: Hive OS (Oozie server)
Create DATABASE hive DEFAULT CHARSET UTF8 COLLATE utf8_general_ci;

Create database am DEFAULT CHARSET UTF8 COLLATE utf8_general_ci;

Create DATABASE rm DEFAULT CHARSET UTF8 COLLATE utf8_general_ci;

Create database OS DEFAULT CHARSET UTF8 COLLATE utf8_general_ci;

8. Backup system

Everything's ready. To back up the system, the installation fails and can be restored
Tar cvpzf backup.tgz/--exclude=/proc--exclude=/lost+found--exclude=/backup.tgz--exclude=/mnt--exclude=/sys
Tar cvpjf backup.tar.bz2/--exclude=/proc--exclude=/lost+found--exclude=/backup.tar.bz2--exclude=/mnt--exclude=/ Sys
Statements that are restored
Tar Xvpfz backup.tgz-c/
Tar xvpfj backup.tar.bz2-c/
9. Start the server
Sudo/opt/cm-5.5.0/etc/init.d/cloudera-scm-server start
10. Start Agent
Scp-r/opt/cm-5.5.0 [Email protected]:/opt
Sudo/opt/cm-5.5.0/etc/init.d/cloudera-scm-agent start

11. Start the installation
