apache to tomcat:mod_jk vs mod_proxy

Question

使用mod_jk和mod_proxy使用apache前端tomcat实例的优点和缺点是什么？

我已经在生产中使用mod_jk多年了,但我听说它是​​面向tomcat的"旧方式".我应该考虑改变吗？会有什么好处吗？

Answer 1

存在这些模块的利弊比较 http://blog.jboss.org/

mod_proxy的

* Pros:
      o No need for a separate module compilation and maintenance. mod_proxy,
        mod_proxy_http, mod_proxy_ajp and mod_proxy_balancer comes as part of 
        standard Apache 2.2+ distribution
      o Ability to use http https or AJP protocols, even within the same 
        balancer.
* Cons:
      o mod_proxy_ajp does not support large 8K+ packet sizes.
      o Basic load balancer
      o Does not support Domain model clustering

mod_jk的

* Pros:
      o Advanced load balancer
      o Advanced node failure detection
      o Support for large AJP packet sizes
* Cons:
      o Need to build and maintain a separate module

Answer 2

如果你想留在Apache的土地,你也可以尝试更新的mod_proxy_ajp,它使用AJP协议与Tomcat通信而不是普通的旧HTTP,但它利用mod_proxy来完成工作.
