Initializing MariaDB database


PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:

scl enable rh-mariadb102 -- '/opt/rh/rh-mariadb102/root/usr/libexec/mysqladmin' -u root password 'new-password'
scl enable rh-mariadb102 -- '/opt/rh/rh-mariadb102/root/usr/libexec/mysqladmin' -u root -h 480e4a04dbf1 password 'new-password'

Alternatively you can run:
scl enable rh-mariadb102 -- '/opt/rh/rh-mariadb102/root/usr/libexec/mysql_secure_installation'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the MariaDB Knowledgebase at http://mariadb.com/kb or the
MySQL manual for more instructions.

各種確認

# service rh-mariadb102-mariadb start
Database MariaDB is probably initialized in /var/opt/rh/rh-mariadb102/lib/mysql already, nothing is done.
If this is not the case, make sure the /var/opt/rh/rh-mariadb102/lib/mysql is empty before running mysql-prepare-db-dir.
