Replace all references to /usr/sbin/mysqld (and bin and libexec) with mariadbd, so that the binary server will always be 'mariadbd'. Also update all places that reference the server binary in other ways, such as AppArmor profiles and scripts that previously expected to find a 'mysqld' in process lists.

#
|

# - Create a /etc/my.cnf file with the following information:
|
|
# [mysqld]
|
|
# basedir=<path-to-mysql-installation-directory>
|
|
# - Add the above to any other configuration file (for example ~/.my.ini)
|

# and copy my_print_defaults to /usr/bin
|
|
# - Add the path to the mysql-installation-directory to the basedir variable
|
|
# below.
|
|
#
|
|
# If you want to affect other MariaDB variables, you should make your changes
|
|
# in the /etc/my.cnf, ~/.my.cnf or other MariaDB configuration files.
