yum 源本地化

First of all, you need to prepare the rpm packages, we can download them with yum command, in that way, the dependencies needed by the rpm will also be downloaded.

For example, you are trying to download memcached rpm

yum install --downloadonly --downloaddir=/tmp/atomicdownload memcached

The second step is to create the repo.

[root@localhost atomicdownload]# createrepo -p -d -o /tmp/atomicdownload /tmp/atomicdownload
Spawning worker 0 with 1 pkgs
Spawning worker 1 with 0 pkgs
Workers Finished
Saving Primary metadata

Sqlite DBs complete

-p means pretty output

-d means database

-o means output

The last step is to edit the repo file.

vi /etc/yum.repos.d/CentOS-Base.repo

The file content is like below:

[base]
name=da_repo
baseurl=file:///opt/da/da_yum_repo
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

The important configuration is

baseurl  which is the url pointing to the repository

enabled=1 will set this repository active

gpgcheck=0 disable the check
