linux centos&Ubuntu&RedHat更换软件源

linux三大版本更换软件源

前排提示，有的源可能已经失效，如果发现请留言或自行寻找其他源。

1.centos

mv /etc/yum.repos.d/CentOS-Base.repo [--path]
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache

2.Ubuntu

备份原有软件源sudo cp /etc/apt/sources.list <路径>
sudo vi /etc/apt/sources.list
修改为以下:

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

执行更新源sudo apt update

如果有其他错误，可以执行

sudo rm -rf /var/lib/dpkg/info
sudo mkdir /var/lib/dpkg/info

3.RedHat(红帽)更换yum源。

鉴于红帽的软件源需要注册，可以更换为centos的yum。

删除自带的yum

rpm -aq | grep yum | xargs rpm -e –nodeps
