修改docker源和ubuntu源

1、修改docker源

vi /etc/docker/daemon.json
增加或修改成如下内容：
{
   "registry-mirrors": ["https://hub-mirror.c.163.com","https://mirror.baidubce.com","https://vz2hqrw3.mirror.aliyuncs.com"]
}
Docker 官方中国区：https://registry.docker-cn.com
网易：http://hub-mirror.c.163.com
中国科技大学：https://docker.mirrors.ustc.edu.cn
阿里云：https://vz2hqrw3.mirror.aliyuncs.com

#重启docker服务：service docker restart
#查看是否更改生效： docker info|grep Mirrors -A 3 

 

 

2、修改ubuntu系统源

　一般情况下，将/etc/apt/sources.list文件中默认的软件仓库地址和安全更新仓库地址修改为国内的镜像地址即可，比如将deb.debian.org和security.debian.org改为mirrors.xxx.com，并使用https访问，可使用如下命令：

sed -i "s@http://\(deb\|security\).debian.org@http://mirrors.xxx.com@g" /etc/apt/sources.list

修改之后再运行apt update更新索引。

1、查看系统版本,找到对应的codeName
> ~# lsb_release -a
2、选取一个源，修改到文件 ，注意修改为自己的发型代码
>~#  vi /etc/apt/sources.list

>~#  sudo apt-get update    #更新软件包列表
>~#  sudo apt-get upgrade   #升级系统中已安装的软件包到最新版本
