我们知道localhost绑定的是本地主机IP（127.0.0.1），那么我们能不能自定义绑定本地主机IP地址呢？答案是肯定的，同修改hosts文件，我们可以实现上面的需求。
打开本地C盘，找到Windows文件夹-->System32文件夹-->drivers文件夹-->etc文件下的hosts文件，使用管理员身份打开，然后你就知道了。
# 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 localhost127.0.0.1 m.hpugs.com 红色部分即为我设置的绑定本地IP的域名（域名可以随意设置）
