1.Linux中软件包的类型
2.软件包的名称结构
3.rpm命令管理软件包


4.本地软件仓库的搭建

(真机)
cd /var/www/html/
systemctl enable --now httpd打开httpd服务
systemctl disable --now firewalld关闭防火墙

5.dnf 软件管理命令

dnf search /bin/ls 不能搜索文件
search 通过软件搜索软件安装包


echo nameserver 114.114.114.114 > /etc/resolv.conf

yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm
安装 epel 配置包
将 repo 配置中的地址替换为阿里云镜像站地址
sed -i 's|^\#baseurl=https://download.example/pub|baseurl=https://mirrors.aliyun.com|g' /etc/yum.repos.d/epel*
sed -i 's|^metalink|\#metalink|g' /etc/yum.repos.d/epel*
dnf install kolourpaint -y
下载安装包及依赖性(虚拟机实验)
cd /mnt
mkdir westos
ls
yumdownloader --resolve --destdir=/mnt/westos kolourpaint
第三方软件仓库搭建
(虚拟机)
dnf install httpd -y
systemctl enable --now httpd
systemctl disable --now firewalld
cp -r westos /var/www/html
dnf install createrepo -y
createrepo -v /var/www/html/westos
(真机)
dnf remove kolourpaint
vim /etc/yum.repos.d/chen.repo
