关于域名解析即DNS的理解，以及hosts文件跟域名解析的关系。tomcat发布的工程，怎么设置一个虚拟域名？

1修改hosts文件之后，立马就可以生效，不用重启什么的。（亲测有效）

2输入时，不要忘记加上http://，不然无效。

host文件如下，应该输入http://serverTest，而不是直接在浏览器中输入serverTest。

# Copyright (c) 1993-2009 Microsoft Corp.

#

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

#

# This file contains the mappings of IP addresses to host names. Each

# entry should be kept on an individual line. The IP address should

# be placed in the first column followed by the corresponding host name.

# The IP address and the host name should be separated by at least one

# space.

#

# Additionally, comments (such as these) may be inserted on individual

# lines or following the machine name denoted by a '#' symbol.

#

# For example:

#

#      102.54.94.97     rhino.acme.com          # source server

#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.

# 127.0.0.1       localhost

# ::1             localhost

192.168.46.36 serverTest

3host文件，只能设置ip地址，如127.0.0.1，不能设置url网址，如127.0.0.1:8080/testProject/login.html。

5关于域名解析即DNS的理解，以及hosts文件跟域名解析的关系。tomcat发布的工程如http://127.0.0.1:8080/testProject/login.html，怎么怎么设置一个虚拟域名？

很简单：

在hosts文件中增加一行：

127.0.0.1    hello

访问的时候，如此访问：
http://hello:8080/testProject/login.html
