Creating SCM configuration file in /opt/cm-5.13.0/etc/cloudera-scm-server
Executing: /soft/jdk1.8.0_144/bin/java -cp /usr/share/java/mysql-connector-java.jar:/usr/share/java/oracle-connector-java.jar:/opt/cm-5.13.0/share/cmf/schema/../lib/* com.cloudera.enterprise.dbutil.DbCommandExecutor /opt/cm-5.13.0/etc/cloudera-scm-server/db.properties com.cloudera.cmf.db.
[ 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.

java.sql.SQLException: Access denied for user 'root'@'d001' (using password: YES)
