Apache 配置

apache 和 nginx 的實現(xiàn)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>
