Yum简要配置example随记

also alias: DNF 简要配置example随记

直接用directory作为 yum repo

[directory-repo]
name=directory
baseurl=file:///root/directory/os-requirements-resources/repo/centos-7
enabled=1
gpgcheck=0
repo_gpgcheck=0
module_hotfixes=True

directory作为 yum repo的话文件夹下内容概要

[root@localhost centos-7]# ls -a
.  ..  Packages  repodata

repodata下内容概要

[root@localhost centos-7]# cd repodata/
[root@localhost repodata]# ls
17a0c7cff0884d983840e3f4db3e8d56996bd246a95944de35348396bb457d6d-other.sqlite.bz2  4de172fe99a91ec8648e29a0d164d2713ef8341e7a6a2665ef43e409be591cf1-filelists.sqlite.bz2  repomd.xml

[root@localhost repodata]#

可以直接将iso挂载到/mnt/xxx 下然后直接配置yum.repos.d使用

[iso]
name=ISO
baseurl=file:///mnt/os-iso
enabled=1
gpgcheck=0
repo_gpgcheck=0

常规形式

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

centos 8.x 快速换源为 mirrors.ustc.edu.cn

其它8.x版本自行修改releasever版本号

• 注意epel等repo也会读取releasever这个变量，如果是用了epel / remi等软件源，不要直接改全局releasever的值，不然有可能出现拉不到repodata/repomd.xml文件等repo不可用的问题
• echo "8.4.2105" > /etc/yum/vars/releasever; echo "centos-vault" > /etc/yum/vars/contentdir

sed -i -e "s|#baseurl=http://mirror.centos.org|baseurl=https://mirrors.ustc.edu.cn|" -e "s|^mirrorlist|#mirrorlist|" /etc/yum.repos.d/CentOS-Linux-*.repo
sed -i -e "s/\$releasever/8.4.2105/" -e "s/\$contentdir/centos-vault/" /etc/yum.repos.d/CentOS-Linux-*.repo 

centos 7.x 快速换源为 mirrors.ustc.edu.cn (大概率已失效)

sed -i -e "s/^mirrorlist/#mirrorlist/" -e "s/^#baseurl/baseurl/" -e "s#http://mirror.centos.org#https://mirrors.ustc.edu.cn#" /etc/yum.repos.d/*.repo

centos 7.9 换可用源

sed -i -e "s#http://mirror.centos.org#https://i.sanxian.tech#" -e "s/^mirrorlist=/#&/" -e "s/^#\(baseurl=\)/\1/" /etc/yum.repos.d/*.repo
