我没有RHEL订阅,我想更新我的服务器.谁能告诉我如何使用CentOS Repos更新红帽企业 Linux 5.4？

好的,我想通了.我创建了一个文件CentOs.repo(/etc/yum.repos.d/CentOs.repo),其中包含以下内容：

gpgcheck=1
enabled=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

[CentOS-Updates]

gpgcheck=1
enabled=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
