|
notes:
|
|
- Requires the MySQLdb Python package on the remote host. For Ubuntu, this
|
|
is as easy as apt-get install python-mysqldb. (See M(apt).)
|
|
- Both I(login_password) and I(login_user) are required when you are
|
|
passing credentials. If none are present, the module will attempt to read
|
|
the credentials from C(~/.my.cnf), and finally fall back to using the MySQL
|
|
default login of C(root) with no password.
