salt.modules.mysql

Module to provide MySQL compatibility to salt.

depends:
  • MySQLdb Python module

注解

On CentOS 5 (and possibly RHEL 5) both MySQL-python and python26-mysqldb need to be installed.

configuration:

In order to connect to MySQL, certain configuration is required in /etc/salt/minion on the relevant minions. Some sample configs might look like:

mysql.host: 'localhost'
mysql.port: 3306
mysql.user: 'root'
mysql.pass: ''
mysql.db: 'mysql'
mysql.unix_socket: '/tmp/mysql.sock'
mysql.charset: 'utf8'

You can also use a defaults file:

mysql.default_file: '/etc/mysql/debian.cnf'

在 2014.1.0 版更改: 'charset' connection argument added. This is a MySQL charset, not a python one.

在 0.16.2 版更改: Connection arguments from the minion config file can be overridden on the CLI by using the arguments defined here. Additionally, it is now possible to setup a user with no password.
