在家搭建web服务器,公网访问不了
大家好,有人搭建过web服务器吗,在自己家里,然后通过公网的IP地址访问。
我现在搭建好了。在局域网内可以通过公网IP地址访问,但是用手机(联通3G)访问公网IP就不行。
我有装花生壳,花生壳的域名在家里的局域网也能访问,但是用手机访问域名也打不开网页。
谢谢各位 懂的大神帮帮忙,帮忙看下是怎么回事。谢谢了!!

你应该在外网访问。
还有默认80端口是 禁用的,电信禁止的。
------解决思路----------------------
家里用的是局域网ip吧,用路由器做个端口映射
一般叫什么虚拟服务器,映射之类的选项,填上内网ip,80端口,就可以用公网ip访问了
------解决思路----------------------
这里有几个问题是需要注意的:
1、局域网中是不能通过外网出口再入局域网的,所以测试时需要从真实的外网访问
2、从3G网络访问不了,不能说明任何问题。因为DNS解析是需要时间的,只有在域名解析被传递到你的一级DNS是,解析才能成功。这个过程所需时间要根据同一地域对该域名访问的频繁程度而定,通常要有3-5天
3、至少目前电信是禁止了这种个人提供 web 服务的行为的
4、花生壳之类的虚拟域名软件,在 ADSL 上都是有效的。但是在小区宽带中就不一定了,只要中途插有路由器,则虚拟域名就失效了
------解决思路----------------------
我很久之前尝试过,也看到过有人说是封了80端口,其实说封了80端口的应该没有仔细测试过。
我经过测试,我们这边的联通是根据协议来封的,你可以试试,不管在哪个端口上,你的上行数据都能发送到你的服务器上,但是你的服务器下行数据却被拦截了。不管你在哪个端口,只要你的IP不是备案的,下行信息全部拦截。
测试代码:
<br /><?php<br />file_put_contents('./test.txt',$_SERVER['REMOTE_ADDR']."\n");<br />?><br />
如果你的情况跟我的类似,会在你的程序目录下生成一个 test.txt 文件,这个文件中有访问你这个服务器的客户端的IP地址。
------解决思路----------------------
开通路由器的应用服务器里的80端口,然后用本地的外网IP就可以访问。
如果你的路由器是和电信的猫一体的,就需要去找电信要你的超级管理密码。
动态IP的话可以使用花生壳之类的动态域名。
------解决思路----------------------
在路由器里做端口隐射啊,把公网ip隐射到你的内网ip上。
------解决思路----------------------
我可以问一下,你这服务器是用于干嘛的吗?

最好用花生壳吧,想了解原理,去理解一下打洞洞的原理

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
