ubuntu How do I configure proxies without GUI?

想法:  我的想法是想是一台国内的 ubuntu 云主机可以通过另外一台在国外（新加坡）的服务器 ，来实现可以访问 google ,哈哈，比较好查资料：）

下面的做法 去修改 /etc/environment 文件，然后重启reboot 这台服务器的话，发现 apt-get install 软件的时候也会走这个代理去装软件，

，哈哈，这个这国内的服务器无法访问，无法安装的一些软件就可以 so easy 的安装了!!! 哇哇哇。。。。。。。。。：）

System-wide proxies in CLI Ubuntu/Server must be set as environment variables. Open the /etc/environment file with vi (or your favorite editor). This file stores the system-wide variables initialized upon boot. Add the following lines, modifying appropriately. You must duplicate in both upper-case and lower-case because (unfortunately) some programs only look for one or the other: http_proxy="http://myproxy.server.com:8080/" https_proxy="http://myproxy.server.com:8080/" ftp_proxy="http://myproxy.server.com:8080/" no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com" HTTP_PROXY="http://myproxy.server.com:8080/" HTTPS_PROXY="http://myproxy.server.com:8080/" FTP_PROXY="http://myproxy.server.com:8080/" NO_PROXY="localhost,127.0.0.1,localaddress,.localdomain.com" apt-get, aptitude, etc. will not obey the environment variables when used normally with sudo. So separately configure them; create a file called 95proxies in /etc/apt/apt.conf.d/, and include the following: Acquire::http::proxy "http://myproxy.server.com:8080/"; Acquire::ftp::proxy "ftp://myproxy.server.com:8080/"; Acquire::https::proxy "https://myproxy.server.com:8080/"; Finally, logout and reboot to make sure the changes take effect. Sources: 1, 2. See 1 in particular for additional help, including a script to quickly turn on/off the proxies.
