使用phpstudy创建网站，只有localhost可以访问，
其他所有网站无法访问，可能是你的账户没有修改vhost的权限
找到 C:\Windows\System32\drivers\etc下的vhost文件，
1、右键属性 将只读去掉
2、把用户对此文件的控制权限全部勾上
3、再重新创建网站，就可以访问了
效果如下 ：
vhost文件
# 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, ***ments (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.*** # source server
# 38.25.63.10 x.acme.*** # x client host
# localhost name resolution is handled within DNS itself.
127.0.0.1 localhost
# ::1 localhost
# 添加的新域名
127.0.0.1 abc.***
127.0.0.1 erp.***
