hosts文件被删除了如何解决

一、给etc目录授权

进入c:\windows\system32\drivers\etc

选中etc目录，右键-属性-高级

二、恢复hosts文件

进入目录C:\Windows\System32\drivers\etc

新建hosts.txt，将下面内容复制到hosts.txt中

# 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

然后通过重命名的方式去掉后缀，变为hosts
