由于 Github 的部署环境,国内访问 G itHub 会异常缓慢,在 clone 仓库时经常会非常慢,甚至会出现 GitHub 的 web 界面因为无法登录。

下面我们通过修改系统 hosts 文件的办法,直接访问 GitHub 的 CDN 节点,从而达到加速的目的。

获取 GitHub 官方 CDN 地址

记录下查询到的 IP 地址。

修改系统 Hosts 文件

Windows 云服务器修改 Hosts 文件

  1. 打开系统 hosts 文件(需管理员权限).

  2. 在路径:C:\Windows\System32\drivers\etc 的 hosts 文件最后添加第一步获取到的 IP 地址及域名

    如:140.82.112.3 github.com

    # 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
    
    140.82.112.3     github.com
