How to implement CLI client to golang daemon?
问题
我有一个使用Golang编写的Linux守护进程，带有HTTP API。在启动时，它会初始化变量，并且每当我请求API时，它都会进行响应。初始化是一个复杂的操作：读取许多配置文件，添加许多对象等等。
我的问题是，如果主进程死掉，我就无法使用HTTP API。我的代码并不完美，有时会出现堆栈溢出或崩溃，或者用户禁用了Linux服务。但我仍然需要一些低级功能来工作。
如果我尝试在命令行界面实现Web API的所有功能，启动将会非常缓慢，对系统来说也很困难。但是，如果实现在CLI和Web API之间分离，会出现不一致的问题。例如：我可以在Web API内部启动创建操作，同时在CLI内部删除所有操作。我必须实现锁定功能来防止这种情况发生。（我认为在这一方面编写代码并不好）
我不使用数据库服务器（也不需要）。也许我可以将数据存储在文件中或使用一些共享内存？
我的问题是，我如何在Golang守护进程和CLI客户端之间共享对象数据？
英文:
I have a linux daemon with http api which I have wrote on golang. At start he initialize variables and all time when I ask api - he is answer. Init is hard operation: read many config's, add many object's etc.
My problem that if main process die I can't use http api ;). My code isn't perfect and sometimes he stack or die, or user's disable linux service. But I still need some low level functionality to work.
If I try to implement all functions of web api at cli: his start will be very slow and hard for system. But I have more problem if implementation will be separated between CLI & web api: inconsistent. For example: I can start inside web api create && at same time inside CLI - delete all. I must implement lock function to prevent this. (I think write code at this side isn't good)
I don't use database server (and don't need). Maybe I can store inside files or use some shared memory?
My question is how can I share object's data between golang daemon and CLI-client?

Go语言内置了一个用于Go进程之间简单通信的RPC系统。你还可以查看0mq或使用D-Bus。

Go has a built-in RPC system for easy communication between Go processes. You could also take a look at 0mq, or using D-Bus.
