Apache的prefork模式和worker模式

A

模式 这个多路处理模块(MPM)实现了一个非线程型的、预派生的web服务器,它的工作方式类似于Apache 1.3。它适合于没有线程安全库,需要避免线程兼容性问题的系统。它是要求将每个请求相互独立的情况下最好的MPM,这样若一个请求出现问题就不会影响到其他请求。 这个MPM具有很强的自我调节能力,只需要很少的配置指令调整。最重要的是将MaxClients设置为一个足够大的数值以处理潜在的请求高峰,同时又不能太大,以致需要使用的内存超出物理内存的大小。 模式 此多路处理模块(MPM)使网络服务器支持混合的多线程多进程。由于使用线程来处理请求,所以可以处理海量请求,而系统资源的开销小于基于进程的MPM。但是,它也使用了多进程,每个进程又有多个线程,以获得基于进程的MPM的稳定性。...
