一、介绍

功能：salt基于state进行minion的状态管理。

官方介绍：

Salt offers an optional interface to manage the configuration or “state” of the Salt minions. This interface is a fully capable mechanism used to enforce the state of systems from a central manager.

The Salt state system is made to be accurate, simple, and fast. And like the rest of the Salt system, Salt states are highly modular.

二、参考文档

state 介绍文档:
http://docs.saltstack.com/ref/states/
state 模块文档:
http://docs.saltstack.com/ref/states/all/index.html
state 逻辑关系文档:
http://docs.saltstack.com/ref/states/requisites.html
http://docs.saltstack.com/ref/states/ordering.html

三、基本配置

配置结构:

$ID:
   $State:
      - $state: states

示例：

vim:
  pkg:
     

- installed</pre>

如果是redhat系列的就安装 vim-enhanced，如果系统是Debian或者Ubuntu就安装vim-nox

四、逻辑关系

state之间还可以使用require, include, extend等关系进行关联。
require：依赖某个state，在运行此state前，先运行依赖的state，依赖可以有多个

httpd:
  pkg:

- installed

file.managed:

- name: /etc/httpd/conf/httpd.conf
- source: salt://httpd/httpd.conf
- require:
  - pkg: httpd</pre>

watch：在某个state变化时运行此模块

redis:
  pkg:

- latest

file.managed:

- source: salt://redis/redis.conf
- name: /etc/redis.conf
- require:
  - pkg: redis
service.running:
  - enable: True
  - watch:
    - file: /etc/redis.conf
    - pkg: redis</pre>

附：watch除具备require功能外，还增了关注状态的功能

order：优先级比require和watch低，有order指定的state比没有order指定的优先级高

vim:
  pkg.installed:

- order: 1</pre>

想让某个state最后一个运行，可以用last

附：state默认使用jinja（http://jinja.pocoo.org/ ）的模板语法，文档地址： http://jinja.pocoo.org/docs/templates/
