用saltstack cp模块实现文件管理
1.先看配置，2.配置，看日志3，日志不行，只能源代码了基础篇
官网 http://salt.readthedocs.io/en/stable/topics/tutorials/minionfs.html#tutorial-minionfs
第一看卡壳 Saltstack的配置Salt master配置文件
http://blog.csdn.net/zhs2014150551/article/details/48951581
fileserver_backend:
– roots
salt支持模块化的后端文件系统服务器，它允许salt通过第三方的系统来管理收集文件并提供给minions使用，可以配置多个后端文件系统，这里支持gitfs、hgfs、roots、s3fs文件调用的搜索顺序按照后台文件系统的配置顺序来搜索，默认的设置只开启了标准的后端服务器roots，具体的根选项配置通过file_roots参数设置
分发到minion
salt '*' cp.get_filesalt://test.sls /root/test.sls --log-level=all
上传到master
salt '*' cp.push/root/install.log --log-level=all
上传的文件存放在master端的 /var/cache/salt/master/minions/<minion_id>/files/ 目录下
源代码解析

def push(path):
'''
Push a file from the minion up to the master, the file will be saved to
the salt master in the master's minion files cachedir
(defaults to /var/cache/salt/master/minions/files)
Since this feature allows a minion to push a file up to the master server
it is disabled by default for security purposes. To enable add the option:
file_recv: True
to the master configuration and restart the master
CLI Example::
salt '*' cp.push /etc/fstab
'''
path=os.path.basename(path)
if '../' in path or not os.path.isabs(path):
return False
if not os.path.isfile(path):
return False
auth = _auth()
load = {'cmd': '_file_recv',
'id': __opts__['id'],
'path': path.lstrip(os.sep)}
sreq = salt.payload.SREQ(__opts__['master_uri'])
with salt.utils.fopen(path) as fp_:
while True:
load['loc'] = fp_.tell()
load['data'] = fp_.read(__opts__['file_buffer_size'])
if not load['data']:
return True
ret = sreq.send('aes', auth.crypticle.dumps(load))
if not ret:
return ret

用saltstack cp模块实现文件管理、拉取和回滚下发
要实现的效果:
通过mongodb记录数据，然后web api接口渲染配置文件来的更方便。
