How to start a Go program as a daemon in Ubuntu?
问题
在Ubuntu中，启动Go程序作为守护进程的正确方法是什么？然后我将使用Monit来监控它。我应该像这样做吗：
go run myapp.go &;
有没有Go特定的事情我应该考虑？
英文:
What is the proper way to start a Go program as a daemon in Ubuntu ? I will then monitor it with Monit. Should I just do something like:
go run myapp.go &
Are there things specific to Go that I should take into account ?

你应该为你的程序构建一个可执行文件（go build），然后要么为其编写一个 upstart 脚本，它将作为守护进程运行你的程序，要么使用像 daemonize 这样的外部工具。我更喜欢后者的解决方案，因为它不依赖于系统相关的 upstart。使用 daemonize，你可以像这样启动你的应用程序：
daemonize -p /var/run/myapp.pid -l /var/lock/subsys/myapp -u nobody /path/to/myapp.exe
这将为你提供一个行为良好的 Unix 守护进程，daemonize 会完成所有必要的守护进程准备工作。
英文:
You should build an executable for your program (go build) and then either write a script for upstart and it will run your program as a daemon for you, or use an external tool like daemonize. I prefer the latter solution, because it does not depend on a system-dependent upstart. With daemonize you can start your application like
daemonize -p /var/run/myapp.pid -l /var/lock/subsys/myapp -u nobody /path/to/myapp.exe
This will give you a well-behaving unix daemon process with all necessary daemon preparations done by daemonize.

有一个关于在Go程序中守护进程的错误报告：http://code.google.com/p/go/issues/detail?id=227
但是，如果你只是想从进程中分离出来，我看到有以下建议：
nohup go run myapp.go &
或者
go run myapp.go & disown
你还可以使用进程管理器，比如编写一个init.d，Startup，或者使用像Supervisor这样的工具，我个人非常喜欢。
英文:
There is a bug report regarding the ability to daemonize from within a Go program: http://code.google.com/p/go/issues/detail?id=227
But if what you are after is just detaching from the process I have seen recommendations to either do one of the following:
nohup go run myapp.go &
or
go run myapp.go & disown
You can also make use of a process manager, like writing an init.d, Startup, or using something like Supervisor, which I personally really like.
