4是ipv4地址的意思。
访问地址就是这个监听地址的ip或者对应的域名加上端口号。
例如http://1.2.3.4:8080或者http://domain.net:8080

谢谢您的答复。

如果是这样，我在浏览器键入这个地址是否应该可以访问到 Google 页面？

目前我这边环境输入这个地址后（http://1.2.3.4:8080 http://1.2.3.4:8080/ ，IP 已替换，Apache 服务正常）无法打开网页，不知道是否我操作方面还有什么没有理解？

谢谢，

祝好。

你是用Apache做前端反代AirGoogle的吗？如果是，那你就要把apache的配置（和引用的配置）贴出来看看。
最好把你的服务器环境详细的解释一下。

原谅我网络小白了，看到 AirGoogle 以为 Apache 那边不需要设置，临时按网上的说法配置如下，还是不行，不知您可否提供一个本地可用的示例配置？在您有时间的时候，谢谢。

<IfModule mod_proxy.c> 
　ProxyRequests off 
　<Proxy *>     
　　Order deny,allow 
　　Allow from all 
　</Proxy> 
　ProxyPass / http://127.0.0.1:8080 
　ProxyPassReverse / http://127.0.0.1:8080
</IfModule>

看这个apache.conf没啥问题。这样来检查吧，在服务上：
w3m http://localhost:8080 # 检查airGoogle监听是否正常，按q键退出
w3m http://localhost:<apache port> # 看服务器本地apache监听是否正常和反代是否正常
服务上的这2个检查都没问题，而你本地还是不通的话，就要检查你到服务器之间的防火墙问题了。

揣摩了半天，感觉我的 Apache 的代理可能还是写的有问题，运行 node server.js 后则无法加载网页，如下。

~ » w3m http://0.0.0.0:8080
w3m: Can't load http://0.0.0.0:8080.
~ » w3m http://0.0.0.0:80  
w3m: Can't load http://0.0.0.0:80.

注释掉 proxy 配置时 80 端口可以正常访问，8080 没有设置无法加载。

不知道可否提供一个完整的 Apache 反代示例？让新手将该文件追加到 httpd.conf 或者 extra/proxy-html.conf 或者单独 include 进去？

谢谢！

w3m后面的地址不要用0.0.0.0这不是一个合法单播地址，要么用localhost要么用127.0.0.1 loopback地址要么物理网卡地址类似10.x等等。
w3m: Can't load http://0.0.0.0:8080.这个没法说明nodejs的监听是否正常，建议你先检查这部分。

本地测试未成功，目前还没找到原因。

在 nodejitsu 上部署，返回如下错误：

w3m 测试错误如下（与本地部署相同）：

spance avatar spance commented on July 28, 2024

nodejitsu 我没用过，它那个错误中不包括明确的错误原因。
总之，这个部署非常简单。
在服务器上 download这个项目到任意目录下，然后node server.js看到running就说明跑起来了，然后继续用w3m localhost:8080验证。
如果这步有问题，把看到错误告诉我(nodejs错误和其它)；如果没问题，再讨论下一步前端nginx/apache反代的问题。
如果还搞不清的话发邮件给我，约个时间帮你远程看看。

部署Apache为前端是OK的（包括SSL），我这就是用的Apache。
因为本地8080端口被其他进程占用，我需要换个端口，关键就是：

ProxyPass / http://127.0.0.1:8081/
ProxyPassReverse / http://127.0.0.1:8081/

PS：前端强制https的检测对Apache无效，会操作页面loop死掉。我另外起个Issue吧。

前端应该是没有问题的，以下是在 nodejitsu上部署 helloworld 和 airgoogle 的过程和所有提示信息：

Apache 设置如下：

airgoogle git:(master) ✗ » tail -11 /etc/apache2/httpd.conf
<IfModule mod_proxy.c>
    ProxyRequests on 
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>
    ProxyPass /hw http://wangqinhu-helloworld.jit.su
    ProxyPassReverse /hw http://wangqinhu-helloworld.jit.su
    ProxyPass /ag http://wangqinhu-airgoogle.jit.su
    ProxyPassReverse /ag http://wangqinhu-airgoogle.jit.su
</IfModule>

测试结果如下：

~ » w3m http://localhost/hw

hello world

~ » w3m http://localhost/ag

[brand]

400

wangqinhu-airgoogle.jit.su is currently stopped

错误主要是这2句

error:   Error running command deploy
error:   Nodejitsu Error (404): Item not found

你说这里面能看出来什么问题？如果Nodejitsu有客服就要问问了，或者换吧。
你可以试试在vps或者其它各类paas上部署，有很多人也是这么搞的，都没有问题。
比如看一个武汉同学的例子 https://hjc.im/oah-test/
另外，这俩天很快就会发新版本。

感谢 @spance 的热心解答，问题已解决：将 package.json 内的版本号改成 1.0.0 即可成功部署在 nodejitsu，当前版本 1.1.0 可以直接部署成功。
感谢给大家带来 airGoogle！
