To be a public network yum source

1. Network YUM source uses 163yum source

1. Go to the http://mirrors.163.com/.help/centos.html website to download the corresponding yum file (

CentOS7

CentOS6

CentOS5) CentOS-Base-163.repo, put in / etc/yum.repos.d/

two。 Run yum makecache to generate cache

3.yum search softwarename search software

4.yum list softwarename lists installed software

5.yum install softwarename installation software

6.yun remove softwarename Uninstall Software

(sohu yum source: http://mirrors.shou.com, is used in the same way)

2. Local yum sources use CD-ROM yum sources

1. Mount the CD

Mount-t iso9660-o loop / dev/cdrom / media/CentOS

two。 Remove the original repo file from the / etc/yum.repos.d directory

3. Create a new repo file

Vi / etc/yum.repos.d/CentOS-Media.repo

Add the following fields:

[c5-media]

Name=CentOS-$releasever-Media

Baseurl= file:///media/CentOS/

Gpgkey= file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

4. Refresh repos

Yum makecache

Reference / etc/yum.repos.d/CentOS-Media.repo file

# CentOS-Media.repo

#

# This repo is used to mount the default locations for a CDROM / DVD on

# CentOS-5. You can use this repo and yum to install items directly off the

# DVD ISO that we release.

#

# To use this repo, put in your DVD and use it with the other repos too:

# yum-- enablerepo=c5-media [command]

#

# or for ONLY the media repo, do this:

#

# yum-- disablerepo=\ *-- enablerepo=c5-media [command]

[c5-media]

Name=CentOS-$releasever-Media

Baseurl= file:///media/CentOS/

File:///media/cdrom/

File:///media/cdrecorder/

Gpgcheck=1

Enabled=0

Another way: configure yum source under redhat linux

Using the yum source that comes with the redhat linux system seems to be licensed and costs a fee. Using the CentOS source is free and easy to configure.

1.#cd / etc/yum.repos.d/ # Open source path

2.#wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo # download the source of CentOS

3.#yum install softwarename

Attachment: the yum source used by CentOS is configured in two files under the / etc/yum.repos.d/ directory, where:

CentOS-Base.repo is the source of configuration network yum

CentOS-Media.repo is the local yum source for configuration

Configure network yum source 7:

-wget-O / etc/yum.repos.d/centos.repo http://mirrors.aliyun.com/repo/Centos-7.repo

Two sed-I's Universe release _ always _ _ seven _ etc/yum.repos.d/centos.repo

3. Clear yum cache, yum clean all

Update the list of yum networks, "yum list"
