Linux和Microsoft向来是水不容，这些年Microsft和Novell合作后情况有了些许的改观。但是想要各自的应用程序能无缝地迁移估计 都是比较困难的事情。而MONO是由Novell公司发起的一个开源项目，用于在Linux环境中提供ASP.NET支持。
#
源码的安装依赖相应的开发包，所以在安装mono之装需先安装apache组件。
#
#yum -y install http*
Mono的安装有多种方式，Redhat Linux下最简单直接 yum 安装，在CentOS5下面，可以通过下面的方式来 yum 安装，建立Mono的更新源
#
#vim /etc/yum.repos.d/Mono.repo
[Mono]
name=Mono Stack (CentOS_5)
type=rpm-md

[root@localhost yum.repos.d]# rpm -qa|grep mono

虎子哥说 ：对应到虚拟机的例子，你需要查看vim /etc/httpd/conf.d/mono.conf 里的配置写法，
注意这一条：MonoServerPath /usr/bin/mod-mono-server2
这一条就是要求你配置的mono的2.0.50727方式运行，否则默认会以1.1的方式运行。
[root@goosns conf.d]# cat mod_mono.conf
# mod_mono.conf
# Acthung! This file may be overwritten
# Use 'include mod_mono.conf' from other configuration file
# to load mod_mono module.
<IfModule !mod_mono.c>
