Mysql Operations

Manage MySQL databases, users and privileges.

Requires the mysql CLI executable on the target host(s).

All operations in this module take four optional global arguments:

• mysql_user: the username to connect to mysql to
• mysql_password: the password for the connecting user
• mysql_host: the hostname of the server to connect to
• mysql_port: the port of the server to connect to

See the example/mysql.py

mysql.database

Add/remove MySQL databases.

mysql.database(
    database, present=True, collate=None, charset=None, user=None, user_hostname='localhost',
    user_privileges='ALL', mysql_user=None, mysql_password=None, mysql_host=None,
    mysql_port=None,
)

• name: the name of the database
• present: whether the database should exist or not
• collate: the collate to use when creating the database
• charset: the charset to use when creating the database
• user: MySQL user to grant privileges on this database to
• user_hostname: the hostname of the MySQL user to grant
• user_privileges: privileges to grant to any specified user
• mysql_*: global module arguments, see above

Collate/charset:

these will only be applied if the database does not exist - ie pyinfra will not attempt to alter the existing databases collate/character sets.

Example:

mysql.database(
    name='Create the pyinfra_stuff database',
    database='pyinfra_stuff',
    user='pyinfra',
    user_privileges=['SELECT', 'INSERT'],
    charset='utf8',
)

mysql.dump

Dump a MySQL database into a .sql file. Requires mysqldump.

mysql.dump(
    dest, database=None, mysql_user=None, mysql_password=None, mysql_host=None,
    mysql_port=None,
)

• dest: name of the file to dump the SQL to
• database: name of the database to dump
• mysql_*: global module arguments, see above

Example:

mysql.dump(
    name='Dump the pyinfra_stuff database',
    dest='/tmp/pyinfra_stuff.dump',
    database='pyinfra_stuff',
)

mysql.load

Load .sql file into a database.

mysql.load(src, database=None, mysql_user=None, mysql_password=None, mysql_host=None, mysql_port=None)

• src: the filename to read from
• database: name of the database to import into
• mysql_*: global module arguments, see above

Example:

mysql.load(
    name='Import the pyinfra_stuff dump into pyinfra_stuff_copy',
    src='/tmp/pyinfra_stuff.dump',
    database='pyinfra_stuff_copy',
)

mysql.privileges

Add/remove MySQL privileges for a user, either global, database or table specific.

mysql.privileges(
    user, privileges, user_hostname='localhost', database='*', table='*', present=True,
    flush=True, mysql_user=None, mysql_password=None, mysql_host=None, mysql_port=None,
)

• user: name of the user to manage privileges for
• privileges: list of privileges the user should have
• user_hostname: the hostname of the user
• database: name of the database to grant privileges to (defaults to all)
• table: name of the table to grant privileges to (defaults to all)
• present: whether these privileges should exist (False to ``REVOKE)
• flush: whether to flush (and update) the privileges table after any changes
• mysql_*: global module arguments, see above

mysql.sql

Execute arbitrary SQL against MySQL.

mysql.sql(sql, database=None, mysql_user=None, mysql_password=None, mysql_host=None, mysql_port=None)

• sql: SQL command(s) to execute
• database: optional database to open the connection with
• mysql_*: global module arguments, see above

mysql.user

Add/remove/update MySQL users.

mysql.user(
    user, present=True, user_hostname='localhost', password=None, privileges=None,
    mysql_user=None, mysql_password=None, mysql_host=None, mysql_port=None,
)

• user: the name of the user
• present: whether the user should exist or not
• user_hostname: the hostname of the user
• password: the password of the user (if created)
• privileges: the global privileges for this user
• mysql_*: global module arguments, see above

Hostname:

this + name makes the username - so changing this will create a new user, rather than update users with the same name.

Password:

will only be applied if the user does not exist - ie pyinfra cannot detect if the current password doesn’t match the one provided, so won’t attempt to change it.

Example:

mysql.user(
    name='Create the pyinfra@localhost MySQL user',
    user='pyinfra',
    password='somepassword',
)
