saltstack master安装
Saltstack简介：Saltstack是一个新的基础设施管理工具。其两大功能：远程执行和配置管理，在互联网企业IT运维中已经广泛运用。
SaltStack 是一种基于C/S架构的服务模式，在SaltStack架构中服务器端叫作Master，客户端叫作Minion，在实际环境中一般使用SaltStack的C/S架构进行配置管理。
在Master和Minion端都是以守护进程的模式运行，一直监听配置文件里面定义的ret_port（接受minion请求，默认端口号：4506）和publish_port（发布消息，默认端口号：4505）的端口。当Minion运行时会自动连接到配置文件里面定义的Master地址ret_port端口进行连接认证。默认客户端请求id是socket.getfqdn()取到的值，也可以在Minion启动之前修改Minion的id值。
