# Apache 配置 apache 和 nginx 的實現原理一樣，都是做一個反向代理，把請求向后端傳遞，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> ```
