1 安装yum-utils包，yum-utils可以将需要的包下载在本地，安装后可以使用yumdownloader
|
yum -y install yum-utils*
|
2 建立目录/yum/yum-custom存放yum包。
|
mkdir -p /yum/yum-custom
mkdir -p /yum/yum-custom/packages
|
3 安装createrepo
|
yum install yum-utils createrepo yum-plugin-priorities
|
4 下载相关yum数据包到/yum/yum-custom，并创建本地源
|
yumdownloader --resolve --destdir=/yum/yum-custom/packages httpd
yumdownloader --resolve --destdir=/yum/yum-custom/packages vsftpd
createrepo /yum/yum-custom/
|
5 建立目录备份原来的yum源。
|
mkdir /yum/yumbackup
mv /etc/yum.repos.d/* /yum/yumbackp/
|
6 编辑yum源
|
[root@localhost yum.repos.d]# pwd
/etc/yum.repos.d
[root@localhost yum.repos.d]# cat /etc/yum.repos.d/local.repo
[local-base]
name=local-base
baseurl=file:///yum/yum-custom/
gpgcheck=0
enabled=1
