CentOS 7 steps to create a local Yum source

The "local Yum source" in this article includes three types: one is to use the CentOS disc directly as a local Yum source, the advantage is simple and convenient, the disadvantage is that the CD package may be incomplete (CentOS 7 Everything A total of 6.57G) The second is synchronized CentOS official source to the local (equivalent to creating a common mirror), the advantage is the most reliable, the disadvantage is the space charge traffic; third, create a fully customizable local source, the advantage is the most flexible, the disadvantage is only as a supplement to other sources.
First, use CentOS CD-ROM as a local Yum source

(1) on the physical machine directly into the CD-ROM
(2) VMware Workstation virtual machine: virtual machine--> removable device-->cd/dvd--> connection

The code is as follows	Copy Code
Mkdir/mnt/cdrom #创建目录 Mount/dev/cdrom/mnt/cdrom #挂载 Umount/mnt/cdrom #卸载

If you do not want to put the disc every time, then copy the CD file to the local hard drive bar

Cp-avf/mnt/cdrom/yum #-A: This option preserves links, file attributes, and recursively copies the directory

2. Create repo files

The code is as follows	Copy Code
Cat >>/etc/yum.repos.d/centos-local.repo<<-eof [Local] Name=local Yum baseurl=file:///yum/ Gpgcheck=1 Gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-centos-7 Enabled=1

Q: Why not even Createrepo software is installed?

The role of Createrepo is to create an index file (located in the Repodata folder), which even has gpg-key.
Ii. How to create a public mirror for CentOS

For more information, see Official Chinese documents:

Http://wiki.centos.org/zh/HowTos/CreatePublicMirrors

Provides a shell script, and then Cron runs automatically ~ ~

The script is slightly modified to replace the USTC mirror source. Available Mirrors list See:

http://www.centos.org/download/mirrors/

The code is as follows	Copy Code
Localpath= "/mirrors/centos" Mirror= "Mirrors.hustunique.com::centos" rsync= "Rsync-avzh--delete" verlist= "7" baselist= "Centosplus Extras fasttrack OS Updates" Archlist= "x86_64" For ver in $verlist Todo For base in $baselist Todo For the arch in $archlist Todo remote= $mirror/$ver/$base/$arch/ MKDIR-PV $localpath/$ver/$base/$arch/ $rsync $remote $localpath/$ver/$base/$arch/ Done Done Done

Third, create a fully customized local source

The usual collection of some RPM packages in a directory, become a custom source, you can use Yum to manage, flexibility is quite large.

Official tutorials: How to setup your own package repository

1. Create local Yum Warehouse

Mkdir-p/yum/local #可以有N级目录 CP ... #复制RPM包到上述目录

2. Create repo files

The code is as follows	Copy Code
Cat >>/etc/yum.repos.d/centos-local.repo<<-eof [Local] Name=local Yum baseurl=file:///yum/ Gpgcheck=1 Gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-centos-7 Enabled=1

3. Installation Createrepo

The code is as follows	Copy Code
Yum Install Createrepo #使用yum安装createrepo RPM-IVH http://mirror.centos.org/centos/7/os/x86_64/Packages/createrepo-0.9.9-23.el7.noarch.rpm

4. CREATE index

The code is as follows	Copy Code
Createrepo/yum Yum Makecache #更新缓存
