一.正向代理和反向代理
启用反向代理
ProxyPass "/" "http://www.example.com/"
ProxyPassReverse "/" "http://www.example.com/"
特定URL反向代理
ProxyPass "/images" "http://www.example.com/"
ProxyPassReverse "/images" http://www.example.com/
示例：
<VirtualHost *>
ServerName www.yinzhengjie.org.cn
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
</VirtualHost>
二.反向代理配置实战
1>.试验节点角色分配

三.httpd服务的应用
httpd主要应用在于web服务器，比如常见的lamp架构。 httpd可以支持反向代理的功能，但和nginx，haproxy相比httpd显得有点逊色了。 生产环境中httpd做反向代理的案例特别的少，因此不推荐大家使用httpd做反向代理，推荐使用专业的nginx或者haproxy来做反向代理。
