如何将linux环境做成docker镜像 把整个linux系统做成镜像

几种常用Linux系统的软件镜像源配置

1、CentOS6系统的软件镜像源配置

CentOS 6操作系统版本结束了生命周期(EOL)，Linux社区已不再维护该操作系统版本。 

2020年11月30日CentOS 6 EOL 按照社区规则，CentOS 6的源地址http://mirror.centos.org/centos-6/内容已移除，目前第三方的镜像站中均已移除CentOS 6的源。

不过目前测试可以继续使用腾讯云软件镜像站中CentOS6的软件镜像源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos6_base.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.cloud.tencent.com/repo/epel-6.repo

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos6_base.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.cloud.tencent.com/repo/epel-6.repo

如果要用aliyun镜像站，可以参考如下文档 https://help.aliyun.com/document_detail/193569.html 

阿里云的源http://mirrors.cloud.aliyuncs.com和http://mirrors.aliyun.com也无法同步到CentOS 6的源。当在阿里云上继续使用默认配置的CentOS 6的源会发生报错。

建议升级操作系统至CentOS 7及以上，如果业务过渡期仍需要使用CentOS 6系统中的一些安装包，可以通过以下步骤，在CentOS 6操作系统中将源配置按照网络环境不同进行切换。

1)专有网络VPC类型实例需切换为http://mirrors.cloud.aliyuncs.com/centos-vault/6.10/源。

2)经典网络类型实例需切换为http://mirrors.aliyuncs.com/centos-vault/6.10/源

3)EPEL源可以切换到http://mirrors.aliyun.com/epel-archive/6/

2、CentOS7系统的软件镜像源配置

CentOS7为目前主流的服务器操作系统 

可以使用腾讯云软件镜像站中CentOS7的软件镜像源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.cloud.tencent.com/repo/epel-7.repo

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.cloud.tencent.com/repo/epel-7.repo

当然你也可以使用阿里云镜像站中CentOS7的软件镜像源

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

3、Debian10系统的软件镜像源配置

Debian源的使用需要以root权限修改/etc/apt/sources.list配置文件，修改之前，请做好备份 

debian10.x(buster)为例

vi /etc/apt/sources.list
其它行都注释掉，最下行新增如下行
deb https://mirrors.cloud.tencent.com/debian/ buster main contrib non-free
deb https://mirrors.cloud.tencent.com/debian/ buster-updates main contrib non-free
deb https://mirrors.cloud.tencent.com/debian/ buster-backports main contrib non-free
deb https://mirrors.cloud.tencent.com/debian-security buster/updates main contrib non-free
deb-src https://mirrors.cloud.tencent.com/debian/ buster main contrib non-free
deb-src https://mirrors.cloud.tencent.com/debian/ buster-updates main contrib non-free
deb-src https://mirrors.cloud.tencent.com/debian/ buster-backports main contrib non-free
deb-src https://mirrors.cloud.tencent.com/debian-security buster/updates main contrib non-free

vi /etc/apt/sources.list
其它行都注释掉，最下行新增如下行
deb https://mirrors.cloud.tencent.com/debian/ buster main contrib non-free
deb https://mirrors.cloud.tencent.com/debian/ buster-updates main contrib non-free
deb https://mirrors.cloud.tencent.com/debian/ buster-backports main contrib non-free
deb https://mirrors.cloud.tencent.com/debian-security buster/updates main contrib non-free
deb-src https://mirrors.cloud.tencent.com/debian/ buster main contrib non-free
deb-src https://mirrors.cloud.tencent.com/debian/ buster-updates main contrib non-free
deb-src https://mirrors.cloud.tencent.com/debian/ buster-backports main contrib non-free
deb-src https://mirrors.cloud.tencent.com/debian-security buster/updates main contrib non-free

4、Fedora33系统的软件镜像源配置

Fedora 33

cd /etc/yum.repos.d/
mkdir /etc/yum_repo_default_bak
mv *.repo /etc/yum_repo_default_bak/

cd /etc/yum.repos.d/
mkdir /etc/yum_repo_default_bak
