Redhat系统安装YUM(使用CentOS的KEY)

一般来说安装完OS之后就已经安装好YUM了。只需导入可用的KEY和YUM源就可以了。

可以使用CentOS的KEY。

如果没有安装YUM，可先到（http://centos.ustc.edu.cn/centos/）下载合适的RPM包，安装YUM

导入KEY（下载的KEY需根据OS系统版本下载）：

# cd /etc/pki/rpm-gpg/

# wget http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5
# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*

修改repo文件：

#Vi /etc/yum.repos.d/rhel-debuginfo.repo

用以下内容或其他可用的内容将原文内容替换：

需要注意的是，以下的‘5’根据安装的Redhat系统的版本来设置，

这样就可以使用YUM了。

在使用YUM安装软件之前，可以先升级RMP和YUM本身。
