多台机器
当需要修改多台机器的源的时候，上面那种方式就有点麻烦了，其实这些工作都可以通过脚本来做的。脚本下载。

配置好hosts，在执行脚本的机器上的hosts文件中添加所有机器名和IP映射关系。
修改脚本文件中batch_change_apt_source.sh的机器名称，即SERVERS变量。
设置可执行权限

chmod 777 batch_change_apt_source.sh
chmod 777 change_apt_source.sh

执行batch_change_apt_source.sh

./batch_change_apt_source.sh

过程中可能会提示输入机器密码和Y/N
