yum install salt-master
yum install salt-minionThe Salt master communicates with the minions using an AES-encrypted ZeroMQ connection. These communications are done over ports 4505 and 4506, which need to be accessible on the master only. This document outlines suggested firewall rules for allowing these incoming connections to the master.
Note
No firewall configuration needs to be done on Salt minions. These changes refer to the master only.二、配置在master端配置vim /etc/salt/master
interface: 192.168.56.102写成你本机的ip在slave端配置vim /etc/salt/minion
master: 192.168.56.102写你服务端的ipid: localhost是注明自己的标示。客户端/etc/init.d/salt-minion start 日志文件默认是这个/var/log/salt/minion服务端/etc/init.d/salt-master start 日志文件默认是这个/var/log/salt/master[root@centos salt]# salt-key -L

centos下面是一些关于client的描述Python client API
Salt is written to be completely API centric, Salt minions and master can be built directly into third party applications as a communication layer. The Salt client API is very straightforward.运行单个命令>>> import salt.client
>>> a=salt.client.LocalClient()
>>> a
<salt.client.LocalClient object at 0x1ad8f10>
>>> a.cmd("localhost","test.ping")
{'localhost': True}
>>> a.cmd("*","test.ping")
{'server.hadoop.com': True, 'localhost': True}
>>> a.cmd("*","dl.time")
{'server.hadoop.com': 'Wed Aug 14 09:53:22 2013', 'localhost': 'Wed Aug 14 09:53:22 2013'}运行多个命令>>> a.cmd('*',['cmd.run','test.ping','dl.time'],[['hostname'],[],[]])
{'server.hadoop.com': {'test.ping': True, 'dl.time': 'Wed Aug 14 10:01:35 2013', 'cmd.run': 'server.hadoop.com'}, 'localhost': {'test.ping': True, 'dl.time': 'Wed Aug 14 10:01:35 2013', 'cmd.run': 'centos'}}具体参考http://docs.saltstack.com/ref/python-api.html对于具有离线功能的智能手机应用程序，我正在为Xml文件创建单向文本同步。我希望我的服务器将增量/差异(例如GNU差异补丁)发送到目标设备。这是计划:Time=0Server:hasversion_1ofXmlfile(~800kiB)Client:hasversion_1ofXmlfile(~800kiB)Time=1Server:hasversion_1andversion_2ofXmlfile(each~800kiB)computesdeltaoftheseversions(=patch)(~10kiB)sendspatchtoClient(~10kiBtransferred)Cl

我打算为ruby脚本创建一个安装程序，但我希望能够确保机器安装了RVM。有没有一种方法可以完全离线安装RVM并且不引人注目(通过不引人注目，就像创建一个可以做所有事情的脚本而不是要求用户向他们的bash_profile或bashrc添加一些东西)我不是要脚本本身，只是一个关于如何走这条路的快速指针(如果可能的话)。我们还研究了这个很有帮助的问题:RVM-isthereawayforsimpleofflineinstall?但有点误导，因为答案只向我们展示了如何离线在RVM中安装ruby。我们需要能够离线安装RVM本身，并查看脚本https://raw.github.com/wayn
我构建了两个需要相互通信和发送文件的Rails应用程序。例如，一个Rails应用程序会发送请求以查看其他应用程序数据库中的表。然后另一个应用程序将呈现该表的json并将其发回。我还希望一个应用程序将存储在其公共(public)目录中的文本文件发送到另一个应用程序的公共(public)目录。我从来没有做过这样的事情，所以我什至不知道从哪里开始。任何帮助，将不胜感激。谢谢! 最佳答案 无论Rails是什么，几乎所有Web应用程序都有您的要求，大多数现代Web应用程序都需要相互通信。但是有一个小小的理解需要你坚持下去，网站不应直接访问彼此
