安装yum-priorities插件

1.安装yum-priorities插件这个插件是用来设置yum在调用软件源时的顺序的。因为官方提供的软件源，都是比较稳定和被推荐使用的。因此，官方源的顺序要高于第三方源的顺序。如何保证这个顺序，就需要安装yum-priorities这插件了。[[e-mail] ~]# yum install yum-priorities #安装yum-prioritiesPS:这里centos的配置需要配置一个.repo的文件，redhat里面没有文件，也不需要进行配置下载并安装EPEL的rpm，官网的下载已经链接失效，我打包了一个http://download.csdn.net/detail/fzxy002763/4206410下载完了rpm -ivh epel-release-5-4.noarch.rpm  然后导入DAG的PGP Key[[e-mail] ~]# rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL设置/etc/yum.repos.d/epel.repo文件中源的级别，添加priority=11如下：    [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=11    [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    [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=12.下载与安装相应rpmforge的rpm文件包这里打包好了http://download.csdn.net/detail/fzxy002763/4206422直接rpm -ivh rpmforge-release-0.5.1-1.el5.rf.i386.rpm  安装DAG的PGP Key[[e-mail] ~]# rpm –import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt验证rpmforge的rpm文件包(可以略过，直接安装就好）[[e-mail] ~]# rpm -K rpmforge-release-0.5.1-1.el5.rf.*.rpm安装rpmforge的rpm文件包[[e-mail] ~]# rpm -i rpmforge-release-0.5.1-1.el5.rf.*.rpm设置/etc/yum.repos.d/rpmforge.repo文件中源的级别，添加priority=12如下：    ### Name: RPMforge RPM Repository for Red Hat Enterprise 5 – dag    ### URL: http://rpmforge.net/    [rpmforge]    name = Red Hat Enterprise $releasever – RPMforge.net – dag    baseurl = http://apt.sw.be/redhat/el5/en/$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=12最后测试升级,安装软件的方法和原来一样，yum install xxx就行了[[e-mail] ~]# yum check-updatehttp://www.linuxso.com/architecture/25573.html
