RHEL系列是使用最广的Linux服务器系统之一,但是对于未付费用户,却无法通过Redhat网络安装和更新软件,这不能不说是一个遗憾。其实我们完全可以通过RHEL的同胞兄弟CentOS的源来更新,步骤如下:
1、在 /etc/yum.repos.d/ 目录下新建一个文件 CentOS-Base.repo
#vi CentOS-Base.repo
2、在该文件中录入以下内容并保存(本例的源在撰写本文时是有效的):
[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
3、执行更新:
# yum update
======================================
另外,如果服务器需要通过代理上网,则需要设置一下代理服务器才能进行联网更新:
在 /etc/yum.conf文件加入下面一行内容,指定一下代理服务器参数:
#Set http proxyproxy=http://192.168.1.100:8000
