return的用法网上太多资料了,利用return把结果存入数据库网上已经有现在的:

1、在master端创建数据库:

CREATE DATABASE `salt`DEFAULT CHARACTER SET utf8DEFAULT COLLATE utf8_general_ci;USE `salt`;---- Table structure for table `jids`--DROP TABLE IF EXISTS `jids`;CREATE TABLE `jids` (`jid` varchar(255) NOT NULL,`load` mediumtext NOT NULL,UNIQUE KEY `jid` (`jid`)) ENGINE=InnoDB DEFAULT CHARSET=utf8;---- Table structure for table `salt_returns`--DROP TABLE IF EXISTS `salt_returns`;CREATE TABLE `salt_returns` (`fun` varchar(50) NOT NULL,`jid` varchar(255) NOT NULL,`return` mediumtext NOT NULL,`id` varchar(255) NOT NULL,`success` varchar(10) NOT NULL,`full_ret` mediumtext NOT NULL,KEY `id` (`id`),KEY `jid` (`jid`),KEY `fun` (`fun`)) ENGINE=InnoDB DEFAULT CHARSET=utf8;

创建数据库用户,并授权给minion端:

GRANT ALL PRIVILEGES ON salt.* to ‘salt’@'%’ identified by ‘salt’;

(在实际环境中帐号密码应该复杂一些)

2、在master端,创建自定义return脚本,路径在/srv/salt/_returners目录下

[root@test81 _returners]# cat mysql_return.pyfrom contextlib import contextmanagerimport sysimport jsonimport loggingtry:	import MySQLdb	HAS_MYSQL = Trueexcept ImportError:	HAS_MYSQL = Falselog = logging.getLogger(__name__)def __virtual__():	if not HAS_MYSQL:		return False	return 'test_mysql'def _get_options():	'''	Returns options used for the MySQL connection.	'''	defaults = {'host': '192.168.2.100',				'user': 'salt',				'pass': 'salt',				'db': 'salt',				'port': 3306}	_options = {}	for attr in defaults:		_attr = __salt__['config.option']('mysql.{0}'.format(attr))		if not _attr:			log.debug('Using default for MySQL {0}'.format(attr))			_options[attr] = defaults[attr]			continue		_options[attr] = _attr	return _options@contextmanagerdef _get_serv(commit=False):	'''	Return a mysql cursor	'''	_options = _get_options()	conn = MySQLdb.connect(host=_options['host'], user=_options['user'], passwd=_options['pass'], db=_options['db'], port=_options['port'])	cursor = conn.cursor()	try:		yield cursor	except MySQLdb.DatabaseError as err:		error, = err.args		sys.stderr.write(error.message)		cursor.execute("ROLLBACK")		raise err	else:		if commit:			cursor.execute("COMMIT")		else:			cursor.execute("ROLLBACK")	finally:		conn.close()def returner(ret):	'''	Return data to a mysql server	'''	with _get_serv(commit=True) as cur:		sql = '''INSERT INTO `salt_returns`				(`fun`, `jid`, `return`, `id`, `success`, `full_ret` )				VALUES (%s, %s, %s, %s, %s, %s)'''		cur.execute(sql, (ret['fun'], ret['jid'],							str(ret['return']), ret['id'],							ret['success'], json.dumps(ret)))

注意创建的return名字不要用mysql,这样有可能会和自带的mysql return冲突,至于为什么不用自带的return,我实在找不到配置mysql帐号密码在哪里搞

这里minion端需要用到MySQLdb这个python模块,所以应该先安装这个模块:

/srv/salt/packages/install.sls (目录和文件名都是随便起的)

python26-mysqldb:pkg.installed
salt '*' state.sls packages.install

最后推送刚刚我们自定义的return模块:

salt '*' saltutil.sync_returners

最后测试一下:

salt '*' cmd.run 'df' --return test_mysql

然后可以看到数据库里面有结果:
