hosts文件的重要性想必很多人都不知道,下面小編先為大家介紹hosts文件的作用
hosts是一個(gè)沒(méi)有擴(kuò)展名的系統(tǒng)文件,其基本作用就是將一些常用的網(wǎng)址域名與其對(duì)應(yīng)的IP地址建立一個(gè)關(guān)聯(lián)“數(shù)據(jù)庫(kù)”,
當(dāng)用戶在瀏覽器中輸入一個(gè)需要登錄的網(wǎng)址時(shí),系統(tǒng)會(huì)首先自動(dòng)從Hosts文件中尋找對(duì)應(yīng)的IP地址,一旦找到,系統(tǒng)會(huì)立即打開(kāi)對(duì)應(yīng)網(wǎng)頁(yè),如果沒(méi)有找到,則系統(tǒng)再會(huì)將網(wǎng)址提交DNS域名解析服務(wù)器進(jìn)行IP地址的解析,如果發(fā)現(xiàn)是被屏蔽的IP或域名,就會(huì)禁止打開(kāi)此網(wǎng)頁(yè)!
那么如果hosts文件出錯(cuò)了該怎么辦呢?下面就就隨小編一起來(lái)學(xué)習(xí)一下hosts文件修復(fù)方法吧。
方法一:
1、在c盤(pán)C:\Windows\System32\drivers\etc文件夾中找到hosts文件
2、右鍵使用記事本打開(kāi)
3、將以下內(nèi)容復(fù)制該文件中
# 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
4、保存之后退出即可
方法二:
如方法一無(wú)效,那么就只能將整個(gè)host文件替換了
1、首先我們需要下載正確的hosts文件,下載地址如下:
hosts文件下載,host文件修復(fù)
2、將自己c盤(pán)C:\Windows\System32\drivers\etc中的hosts文件刪除,將新下載的hosts文件放入相同位置
總結(jié):以上就是hosts文件修復(fù)方法了,希望對(duì) 大家有幫助
