Building a yum Warehouse

Basic concepts:

To build a yum warehouse, you first create a file format that ends in. Repo under/etc/yum.repos.d/.

[] #[the ID of the repository must be unique Name= # name is the name of Yum and must be unique baseurl= #指定你访问到那些rpm包的路径gpgc heck= #默认为1, 1 means the check of the public key, when checking the public key to specify the Gpgkey address, 0 means not to check the enable= #默认为1, 1 means to enable this warehouse, 0 means to close

Build local yum repositories with CDs

Mount the disc to/mnt/cdrom and then create the. repo file under/etc/yum.repod.s/

Mount/dev/sr0/mnt/cdromcat >>/etc/yum.repos.d/iso.repo <<endf[iso]name=rhel-7.1 Server.x86_64baseurl= File:///mnt/cdromgpgcheck=0enable=1ENDF

Setting up a Yum repository outside the network

Cat >>/etc/yum.repos.d/sohu.repo <<endf[sohu]name=internet-centosbaseurl=http://mirrors.sohu.com/ centos/$releasever/os/$basearchgpgcheck =1 #需要检查公匙enable =1gpgkey=http://mirrors.sohu.com/centos/rpm-g Pg-key-centos-6endf

Build yourself a local yum warehouse

Download Createrepo and install the Createrepo will generate a Repodata software information warehouse (in the ISO also has repodata, no this file will not be able to get a good yum warehouse)

Put the downloaded RPM package in a directory such as/rpm_1

Createrepo/rpm_1

A repodata file is generated under/rpm_1

Create the appropriate. Repo file in/etc/yum.repos.d/

Cat >>/etc/yum.repos.d/rpm_1.repo <<endf[rpm_1]name=centos-rpm_1baseurl=file:///rpm_1gpgcheck= 0enable=1endfyum Install Rpm_1

Yum Repolist [All | enable | disable] View the number of Yum warehouses default display enabled warehouses

Yum provides is used to see which package generated a path.
