# Apache 配置 apache 和 nginx 的实现原理一样，都是做一个反向代理，把请求向后端传递，配置如下所示： ``` NameVirtualHost *:80 <VirtualHost *:80> ServerAdmin webmaster@dummy-host.example.com ServerName www.a.com ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://127.0.0.1:8080/ ProxyPassReverse / http://127.0.0.1:8080/ </VirtualHost> <VirtualHost *:80> ServerAdmin webmaster@dummy-host.example.com ServerName www.b.com ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://127.0.0.1:8081/ ProxyPassReverse / http://127.0.0.1:8081/ </VirtualHost> ```
