如何解决服务器80端口被运营商封掉问题

如何解决无公网ip如何假设web服务器

一.拓扑图

二.原理

假设:国内web服务器service2的web端口是990国外服务器service1开启了80端口.

通过架设虚拟局域网将国内web服务器990端口映射转发到国外服务器80端口上达到访问国内web服务器上的网站且不需要输入端口访问.

利用openvpn将service1和service2组建成一个虚拟局域网.虚拟局域网ip需要固定.所以openvpn必须分配给service1虚拟ip是固定的.将service2上的web服务器监听分配给它的虚拟ip.同时service1必须开启80端口,并且开启路由转发功能.当客户端访service1的80端口时.service1就通过路由转发功能将请求包通过虚拟虚拟局域网80端口发送给service2的web端口990上.service2获取到请求后将web数据在通过内网ip的990端口路由转发给service1的80端口上.然后提交给客户端.这样用户访问的就是

国内服务器上的网站.解决了服务器无公网ip和运营商未开启80端口如何将网站强制通过80端口发布出去.也同时解决了无固定公网ip的问题

且.使用的是骨干节点网络service2和service1建议.的请求速度取决于两者间的网络环境service2和Service1

必须是光纤。

三.操作步骤service1和service2以linux系统为主。因为稳定且设置生效不用重启服务器

# php/及数据库服务安装服务apache和–y /yum install httpd mysql-server mysql php php-mysql#service httpd restart /启动apache服务/

#service mysqld restart /mysql服务/

#chkconfig httpd on /设置apache开机启动/

#chkconfig mysqld on /设置mysql开启启动/

#vim/etc/h ttpd/conf/h ttpd.conf /配置apache/

将监听端口修改成990并保存退出

#service httpd restart /启动apache服务/
