node.js - 如何在笔记本电脑服务器上设置 Ghost 博客框架

Question

我正在尝试在本地笔记本电脑开发机器上设置 Ghost 博客框架。我已成功遵循(基本安装说明)[http://docs.ghost.org/installation/mac/]。我可以通过直接访问 IP 来加载页面，即 http://127.0.0.1:2368。然而，我正在努力通过 url(即 mysite.localmachine.net)加载页面。在 config.js 文件中，我进行了如下设置:

config = {
    // ### Development **(default)**
    development: {
        // The url to use when providing links to the site, E.g. in RSS and email.
        url: 'http://myurl',

        database: {
            client: 'sqlite3',
            connection: {
                filename: path.join(__dirname, '/content/data/ghost-dev.db')
            },
            debug: false
        },
        server: {
            // Host to be passed to node's `net.Server#listen()`
            host: '127.0.0.1',
            // Port to be passed to node's `net.Server#listen()`, for iisnode set this to `process.env.PORT`
            port: '2368'
        }
    },

    // ### Production
    // When running Ghost in the wild, use the production environment
    // Configure your URL and mail settings here
    production: {
        url: 'http://myurl',
        mail: {},
        database: {
            client: 'sqlite3',
            connection: {
                filename: path.join(__dirname, '/content/data/ghost.db')
            },
            debug: false
        },
        server: {
            // Host to be passed to node's `net.Server#listen()`
            host: '127.0.0.1',
            // Port to be passed to node's `net.Server#listen()`, for iisnode set this to `process.env.PORT`
            port: '2368'
        }
    },
    ...
    ...
    ...

当我像这样 npm start --product 启动博客时，我收到以下明显成功的加载消息:

> ghost@0.4.0 start /Users/ethan/Sites/ghost
> node index

Ghost is running... 
Your blog is now available on http://myurl 

Ctrl+C to shut down

但是，如果我随后在浏览器中导航到 http://myurl，我会收到一条站点不可用消息。我还尝试将端口设置为 80，我将其视为可能的解决方案(此处)[http://www.howtoinstallghost.com/how-to-install-ghost-on-a-mac-os-x- 10-8-mountain-lion/]，但这会产生如下所示的错误:

events.js:72
        throw er; // Unhandled 'error' event
              ^

此时我有点困惑，并且无法找到关于在任何地方思考配置的方式的清晰解释。如果有人有任何想法，那就太好了。

Answer 1

除非您以 root 身份运行程序，否则无法将程序绑定(bind)到端口 80，并且出于安全原因，您不应该对应用服务器执行此操作。

如果您绑定(bind)到 0.0.0.0 或您的实际 IP 地址，您将能够通过 http://yourhost:2368/ 访问博客

要在端口 80 上运行博客，请将 IP 和端口保留为 127.0.0.1:2368 并运行 apache 或 nginx 作为前端代理，这会以 root 身份运行，但会放弃工作进程的权限。然后，代理请求访问本地主机上的 Node.js 服务器。

另请注意，您的博客在 http://yourhostname:2368/ 处不可用的消息并不意味着它确实可以在那里访问，它只是在配置中配置的 URL(即哪个 url 将用于绝对链接(如 rss)
