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, 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

# 添加的新域名
127.0.0.1  abc.com
127.0.0.1  erp.com
