远程执行命令我使用saltstack这个运维工具，执行一些系统命令可以直接使用salt，执行一些相关的游戏脚本，则可以使用salt的模块功能，最后还可以把结果存入数据库，太方便了
saltstack 自定义modules:http://lihuipeng.blog.51cto.com/3064864/1396279
saltstack return的使用：http://lihuipeng.blog.51cto.com/3064864/1403387
saltstack API的使用：http://docs.saltstack.cn/ref/clients/index.html#localclient
我这里使用了多数据库，django多数据库的配置参考：http://lihuipeng.blog.51cto.com/3064864/1415141
