设置hosts直接把域名映射到服务器IP

开发通常需要从国外网站下载一些工具和插件，例如 IDEA的插件，Github。

因国内访问国外网络各种不可描述问题，通常会非常慢，只要不是被 Great FireWall 给禁了，可以在 host 设置域名映射的IP来加快速度，而不必经过国内各种路由解析转发各种限速。

查看域名映射的IP

国外域名打开网站查询：https://www.ipaddress.com/

编辑 hosts 文件

编辑 hosts 文件，添加域名与IP地址的映射

• Windows：C:\Windows\System32\drivers\etc\hosts
• Linux：/etc/host

示例：

# 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

刷新本地DNS缓存

Windows

# 显示dns缓存
ipconfig /displaydns

#  刷新DNS记录
ipconfig /flushdns

# 重请从DHCP服务器获得IP
ipconfig /renew

Linux

重启网络

sudo /etc/init.d/networking restart

或安装 nscd

# Ubuntu：
apt-get install -y nscd

# CentOS:
yum install -y nscd

# 使用：
service nscd restart
