以前用fedora配置yum很方便,可是來到RHLE就不是那么順手了,如果不做如下設置,經常出現不能通過yum安裝軟件的情況,下面是詳細配置(網上找的)

 

首先，rhel5系統安裝的時候其實已經有yum了，只是因為如果用官方的網站更新的話除非你是用錢買的rhel5.否則它會提示注冊之類的。所以只要把 yum的更新地址改成開源的就行了。而限定yum更新地址的文件在/etc/yum.repos.d/里。先把它們改成備份文件，即在后面加.bak。
[root@killgoogle ~]# mv /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.bak
[root@killgoogle ~]# mv /etc/yum.repos.d/rpmforge.repo.rpmnew /etc/yum.repos.d/rpmforge.repo.rpmnew.bak

 

建立新的配置文件：
[root@killgoogle ~]# cd /etc/yum.repos.d
[root@killgoogle ~]# touch rhel-debuginfo.repo
[root@killgoogle ~]# touch mirrors-rpmforge
[root@killgoogle ~]# touch rpmforge.repo

 

往新的配置文件寫東西：
[root@killgoogle ~]#vi rhel-debuginfo.repo
[base]
name=CentOS-5 - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever5&arch=$basearch&
repo=os
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
baseurl=http://ftp.sjtu.edu.cn/centos/5/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#released updates
[update]
name=CentOS-5 - Updates
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=updates
baseurl=http://ftp.sjtu.edu.cn/centos/5/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#packages used/produced in the build but not released
[addons]
name=CentOS-5 - Addons
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=addons

baseurl=http://ftp.sjtu.edu.cn/centos/5/addons/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#additional packages that may be useful
[extras]
name=CentOS-5 - Extras
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=extras

baseurl=http://ftp.sjtu.edu.cn/centos/5/extras/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-5 - Plus
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=centosplus
baseurl=http://ftp.sjtu.edu.cn/centos/5/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

#contrib - packages by Centos Users
[contrib]
name=CentOS-5 - Contrib
#mirrorlist=http://mirrorlist.centos.org/?release=4&arch=$basearch&repo=contrib
baseurl=http://ftp.sjtu.edu.cn/centos/5/contrib/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

# vi dag.repo
[dag]
name=Dag RPM Repository for RHEL5
baseurl=http://ftp.riken.jp/Linux/dag/redhat/el5/en/$basearch/dag/
enabled=1
gpgcheck=1
gpgkey=http://ftp.riken.jp/Linux/dag/packages/RPM-GPG-KEY.dag.txt

 

修改第二個配置文件：
[root@killgoogle ~]vi mirrors-rpmforge
http://apt.sw.be/redhat/el5/en/$ARCH/dag
http://archive.cs.uu.nl/mirror/dag.wieers/redhat/el5/en/$ARCH/dag
http://ftp2.lcpe.uni-sofia.bg/freshrpms/pub/dag/redhat/el5/en/$ARCH/dag
#http://ftp.heanet.ie/pub/freshrpms/pub/dag/redhat/el5/en/$ARCH/dag
http://ftp-stud.fht-esslingen.de/dag/redhat/el5/en/$ARCH/dag
http://mirror.cpsc.ucalgary.ca/mirror/dag/redhat/el5/en/$ARCH/dag
http://mirrors.ircam.fr/pub/dag/redhat/el5/en/$ARCH/dag
http://rh-mirror.linux.iastate.edu/pub/dag/redhat/el5/en/$ARCH/dag
http://rpmfind.net/linux/dag/redhat/el5/en/$ARCH/dag
http://wftp.tu-chemnitz.de/pub/linux/dag/redhat/el5/en/$ARCH/dag
http://www.mirrorservice.org/sites/apt.sw.be/redhat/el5/en/$ARCH/dag

 

 

修改第三個配置文件：
[root@killgoogle ~]# vi rpmforge.repo
# 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/dag
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

下面有2種方法：

這種我嘗試過，在服務器上已搭建好 yum

參考 ： http://www.linuxdiyf.com/viewarticle.php?id=70630

   這里注意

   vi /etc/yum.conf
    加上這么一句：timeout=120

和 CentOS-Base.repo 文件中的 5.0 都修改為 5.2 就可以了

 

 如果通過上述配置出現類似以下錯誤信息：

 

Downloading Packages:
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 6b8d79e6

下載并導入Key

cd /etc/pki/rpm-gpg
wget http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*

 

其中http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5中的內容如下：

 

 

 

 

解決方法二：

重啟動

service yum-updatesd restart

 

 

 

RHA5上用yum安裝程序時候，出現下面的異常問題：

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897
Is this ok [y/N]: y
Downloading Packages:
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897
   
RHA5
解決辦法：

rpm --import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5

如果是低版本，可以使用

rpm --import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-centos4
