CentOS 5源设置笔记

我使用的是CentOS 5.7，安装时选了Server版。

1、使用快速官方源

推荐使用网易源：

# wget http://mirrors.163.com/.help/CentOS5-Base-163.repo \
-O /etc/yum.repos.d/CentOS-Base.repo

2、源顺序调整软件

即安装yum-priorities：

# sudo yum install yum-priorities

在/etc/yum.repos.d/下的文件中加入priority=N的内容，如CentOS-Base.repo文件：

[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.ustc.edu.cn/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=1
#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.ustc.edu.cn/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=1
#packages used/produced in the build but not released
[addons]
name=CentOS-$releasever - Addons
baseurl=http://mirrors.ustc.edu.cn/centos/$releasever/addons/$basearch/
gpgcheck=1
gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=1
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirrors.ustc.edu.cn/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=1
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://mirrors.ustc.edu.cn/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirrors.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=2

3、EPEL源设置

这个源包含了fedora使用的一些软件为redhat编译的版本。i386系统：

# rpm -ivh http://download.fedora.redhat.com/pub/epel/5/i386/\
epel-release-5-4.noarch.rpm

x86_64系统：

# rpm -ivh http://download.fedora.redhat.com/pub/epel/5/x86_64/\
epel-release-5-4.noarch.rpm

导入pgp key：

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL

设置/etc/yum.repos.d/epel.repo中源的priority：

[epel]
name=Extra Packages for Enterprise Linux 5 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/5/$basearch
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=epel-5&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL
priority=7
[epel-debuginfo]
name=Extra Packages for Enterprise Linux 5 - $basearch - Debug
#baseurl=http://download.fedoraproject.org/pub/epel/5/$basearch/debug
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=epel-debug-5&arch=$basearch
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL
gpgcheck=1
priority=7
[epel-source]
name=Extra Packages for Enterprise Linux 5 - $basearch - Source
#baseurl=http://download.fedoraproject.org/pub/epel/5/SRPMS
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=epel-source-5&arch=$basearch
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL
gpgcheck=1
priority=7

4、rpmforge源设置

这个源包含大量软件且比较稳定。i386系统：

# wget http://pkgs.repoforge.org/rpmforge-release/\
rpmforge-release-0.5.2-2.el5.rf.i386.rpm

x86_64系统：

# wget http://pkgs.repoforge.org/rpmforge-release/\
rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

安装pgp key：

# rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt

验证刚才下载的rpm包：

# rpm -K rpmforge-release-0.5.2-2.el5.rf.*.rpm

安装此rpm包：

# rpm -i rpmforge-release-0.5.2-2.el5.rf.*.rpm

在/etc/yum.repos.d/rpmforge.repo文件中加入priority的设置：

[rpmforge]
name = RHEL $releasever - RPMforge.net - dag
baseurl = http://apt.sw.be/redhat/el5/en/$basearch/rpmforge
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge
enabled = 1
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1
priority=8
[rpmforge-extras]
name = RHEL $releasever - RPMforge.net - extras
baseurl = http://apt.sw.be/redhat/el5/en/$basearch/extras
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge-extras
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge-extras
enabled = 0
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1
priority=8
[rpmforge-testing]
name = RHEL $releasever - RPMforge.net - testing
baseurl = http://apt.sw.be/redhat/el5/en/$basearch/testing
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge-testing
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge-testing
enabled = 0
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1
priority=8

5、更新系统

检测更新：

# yum check-update

更新：

# yum update
