/opt/cm-5.13.0/share/cmf/schema/scm_prepare_database.sh --help usage: /opt/cm-5.13.0/share/cmf/schema/scm_prepare_database.sh [options] (postgresql|mysql|oracle) database username [password] Prepares a database (currently either MySQL, PostgreSQL or Oracle) for use by Cloudera Service Configuration Manager (SCM): o Creates a database (For PostgreSQL and MySQL only) o Grants access to that database, by: - (PostgreSQL) Creating a role - (MySQL) Creating a grant o Creates the SCM database configuration file. o Tests if the database connection parameters are valid. MANDATORY PARAMETERS database type: either "oracle", "postgresql" or "mysql" database: For PostgreSQL and MySQL, name of the SCM database to create. For Oracle this is the SID of the Oracle database. username: Username for access to SCM's database. OPTIONAL PARAMETERS password: Password for the SCM user. If not provided, and --scm-password-script is not specified as an option, will prompt for it. OPTIONS -h|--host Database host. Default is to connect locally. -P|--port Database port. If not specified, the database specific default will be used: namely, 3306 for MySQL, 5432 for PostgreSQL, and 1521 for Oracle. -u|--user Database username that has privileges for creating users and grants. The default is 'centos'. Typical values are 'root' for MySQL and 'postgres' for PostgreSQL. Not applicable for Oracle. -p|--password Database Password. Default is no password. --scm-host SCM server's hostname. Omit if SCM is colocated with MySQL. --config-path Path to SCM configuration files. Default is /etc/cloudera-scm-server. --scm-password-script Instead of obtaining the SCM username's password directly, execute a script whose stdout is used as the password. -f|--force Don't stop when an error is encountered. -v|--verbose Print more informational messages. -?|--help Show this message. NOTE ON POSTGRESQL CONFIGURATION PostgreSQL must be configured to accept connections with md5 password authentication. To do so, edit /var/lib/pgsql/data/pg_hba.conf (or similar) to include "host all all 127.0.0.1/32 md5" _above_ a similar line that allows 'ident' authentication.
