Deploy Go webserver to Google compute engine
问题
我刚开始测试Google计算引擎。现在我正在尝试在上面部署我的Go（golang）应用程序，以便可以从外部访问。我选择使用计算引擎而不是应用引擎，因为我的应用程序需要一个MongoDB数据库。
我按照以下步骤进行操作：
- 创建计算引擎实例。
- 设置防火墙，打开端口1234并设置静态IP。
- 安装MongoDB。
- 上传我的应用程序。
- 启动应用程序。
应用程序启动得很好。但是，如果我在浏览器中使用IP:1234打开它，我无法从外部访问它。我还尝试以root用户的身份在端口80上启动它，但也没有成功。
服务器的配置如下：
{
"host": "localhost:1234",
"dbhost": "localhost",
"db": "dbname",
"logfile": "log"
}
当我使用Apache服务器时，它可以提供端口80并显示页面...操作系统是Ubuntu 14.04。
主要问题可能出在以下代码中，它向mux添加了一些处理程序，并向公共目录添加了一个FileServer：
mux.Handle("/", http.FileServer(http.Dir(public_dir)))
// [...]
if err := http.ListenAndServe(cfg.Host, mux); err != nil {
panic(err)
}
所以问题出在哪里呢？
英文:
I just started to test Google compute engine. Now I'm trying to deploy my Go (golang) application on it, so that it can be reached from outside. I use compute engine in favor of the app engine, since my application requires a MongoDB database.
I did the following:
- create compute engine instance
- setup up firewall so that port 1234 is open and IP is static
- install MongoDB
- upload my application
- start
The application starts just fine. But I cannot reach it from outside if I open it in my browser with ip:1234. I also tried to start it on port 80 as root user, but this didn't work neither.
The server is configured as following:
{
"host": "localhost:1234",
"dbhost": "localhost",
"db": "dbname",
"logfile": "log"
}
When I'm using an apache server it servers port 80 and the page is displayed... OS is ubuntu 14.04.
The main simply adds some handlers to a mux and adds a FileServer to the public dir:
mux.Handle("/", http.FileServer(http.Dir(public_dir)))
// [...]
if err := http.ListenAndServe(cfg.Host, mux); err != nil {
panic(err)
}
So what's the issue here?

尝试将host从localhost更改为0.0.0.0，因为当前它只监听“内部”请求。
英文:
Try changing host from localhost to 0.0.0.0, because right now it's only listening to "inside" requests.
