看惯了http://localhost在本地测试的域名，想换种写法行不行，比如说想变成http://www.ceo.com，但网页访问仍然是原来http://localhost的内容，如何做到呢？
可以修改本机的一个文件来实现。
在系统盘中的如下路径
C:WINDOWSsystem32driversetc
找到“hosts”文件，右键打开方式选择文本文件方式，可以看到如下内容：
# Copyright (c) 1993-1999 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
127.0.0.1 localhost
127.0.0.1 localhost
看到了吧，在最下边一行有
127.0.0.1 localhost
大家知道怎么做了吧？
就是在这行下添加新行，将localhost修改为想要的域名，如下
127.0.0.1 www.ceo.com
需要注意的是，“127.0.0.1”和“www.ceo.com”之间用Tab键间隔开
想添加什么域名就接着往下加好了，就这么简单。
添加完成后就保存，然后就可以用www.ceo.com访问自己本地的网站了。
