Create a local Yum source in centos and update it automatically

1. Although many free images provide Yum source services, it is necessary to establish your own Yum server, mainly for the following considerations:

L network speed: access to the Internet may be slow

L bandwidth saving: if there are a large number of servers, setting up your own Yum source can effectively save Internet bandwidth

L network restrictions: Some Intranet servers cannot connect to the Internet.

L for RHEL (Redhat Enterprise Linux), you need to purchase services

L easy release of self-developed RPM packages

2. Find the yum synchronization Source Suitable for your site, mainly centos standard software repository, epel, and rpmforge

Centos standard repository selection list

Asian:

Http://www.centos.org/modules/tinycontent/index.php? Id = 32

North American

Http://www.centos.org/modules/tinycontent/index.php? Id = 30

Epel source selection list

Http://mirrors.fedoraproject.org/publiclist/EPEL/

Rpmforge Source

Http://apt.sw.be/

Select the region nearest to your local server and support rsync to facilitate updates and synchronization.

I chose Linux kernel archives.

Centos standard software Repository

Rsync: // mirrors.kernel.org/centos

Epel Source

Rsync: // mirrors.kernel.org/fedora-epel

Rpmforge Source

Rsync: // ftp-stud.fht-esslingen.de/dag

Rsync: // mirror. CPSC. ucalgary. ca/DAG

3. Write a synchronization script for automatic synchronization as needed

[[Email protected] bin] # vi update_yum_source.sh

#! /Bin/bash

#===================================================== ===

# Program: update_yum_source.sh

# Info: regularly synchronize the official Yum source to the Local Machine

# Version: 2013.03.05 first release

#===================================================== ===

Date = 'date + % Y % m % d'

Logfile = "/tmp/update_yum_source.log"

Centostrunkver = "5"

Centoscurrentver = "5.9"

Rsyncbin = "/usr/bin/rsync"

Rsyncperm = "-AVRT -- delete -- exclude = debug/-- exclude = ISOs /"

Centos_trunk_ver_path = "/servers/yum_update/$ centostrunkver"

Centos_current_ver_path = "/servers/yum_update/$ centoscurrentver"

Yumsitelist = "rsync: // mirrors.kernel.org/centos"

# Centos 5.9

[[Email protected] bin] # vi update_epel_source.sh

#! /Bin/bash

#===================================================== ===

# Info: regularly synchronize the official epel source to the Local Machine

# Version: 2013.03.05 first release

#===================================================== ===

Date = 'date + % Y % m % d'

Logfile = "/tmp/update_epel_source.log"

Rsyncbin = "/usr/bin/rsync"

Rsyncperm = "-AVRT -- delete -- exclude = 4/-- exclude = 4as/-- exclude = 4es/-- exclude = 4ws/-- exclude = 6/-- exclude = testing /"

#============== Epel ====================

Epelsite = "rsync: // mirrors.kernel.org/fedora-epel"

Epellocalpath = "/servers/epel"

Echo "---- $ date 'date + % t' begin ----"> $ logfile

# Epel

$ Rsyncbin $ rsyncperm $ epelsite $ epellocalpath >>$ logfile

Rsyncbin = "/usr/bin/rsync"

Rsyncperm = "-AVRT -- delete -- exclude = i386/-- exclude = PPC/-- exclude = source /"

# Rpmforge

# Rpmforgesite = "rsync: // apt. Sw. be/RedHat/EL5/en /"

Rpmforgesite = "rsync: // ftp-stud.fht-esslingen.de/dag/redhat/el5/en /"

Rpmforgelocalpath = "/servers/rpmforge"

Echo "---- $ date 'date + % t' begin ----"> $ logfile

# Rpmforge

$ Rsyncbin $ rsyncperm $ rpmforgesite $ rpmforgelocalpath> $ logfile

Echo "---- $ date 'date + % t' end ----"> $ logfile

4. Make a soft connection in the Apache configuration file or modify the main directory pointing

CD/var/www/html/

Ln-S/servers/yum_update/yum

Ln-S/servers/epel

Ln-S/servers/rpmforge

5. Create three repo configuration files respectively, pointing to the server where the local source is located. Pay attention to the directory

[[E-mail protected] yum. Repos. d] # vi CentOS-Base.repo

6. Check whether the GPG key is complete.

[[Email protected] ~] # Ll/etc/pki/rpm-GPG/

Total 24

-RW-r -- 1 Root 1512 Apr 25 2010 rpm-GPG-key-beta

-RW-r -- 1 Root 1504 Apr 25 2010 RPM-GPG-KEY-CentOS-5

-RW-r -- 1 Root 1698 Apr 15 2012 RPM-GPG-KEY-EPEL

If the GPG key is missing, you can use RPM to import it.

# On the local Yum source server

Wget http://apt.sw.be/RPM-GPG-KEY.dag.txt

Music RPM-GPG-KEY.dag.txt rpm-GPG-key-rpmforge

# Run the command on the client that requires Yum Installation

Rpm -- import http: // 172.25.6.8/rpmforge/rpm-GPG-key-rpmforge

7. test whether the three Yum sources are feasible
