[                          main] DbCommandExecutor              INFO  Successfully connected to database.
All done, your SCM database is configured correctly!

我们研究一下 scm_prepare_database.sh的参数

 /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.

 /opt/cm-5.13.0/share/cmf/schema/scm_prepare_database.sh mysql cdh -hd001 -uroot -proot  -pwordemotion  --scm-host d001 root root --force调整成

/opt/cm-5.13.0/share/cmf/schema/scm_prepare_database.sh -hd001 -P3306 --scm-host d001 --force mysql cdh root root
