前言
因為某些因素 RHEL 在沒有開通 RHN 的機制時使用 CentOS YUM 來進行套件安裝或更新。警告： 此舉可能導致 RHEL 運作不正常，建議您還是購買 RHEL License 並使用 RHN 更新機制來進行套件的更新。實作環境
- RHEL 5.6 (x64)
安裝及設定
在設定以前用 yum search drbd 是找不到套件可安裝的，如下所示：# yum search drbd
Loaded plugins: rhnplugin, security
This system is not registered with RHN.
RHN support will be disabled.
Warning: No matches found for: drbd
No Matches found請切換至 /etc/yum.repos.d 資料夾下建立一個副檔名為 .repo 的檔案，例如 centos.repo 然後將 CentOS 中 CentOS-Base.repo 內容貼進來。
- 對 CentOS-Base.repo 內容進行修改。
- 將 CentOS-Base.repo 中 Mirror Site 指向至國內。
- 把 gpgcheck 改成 =0 代表不使用下一行的那個 GPG key 來檢查是否為 RHEL5 原廠套件。 (%s,gpgcheck=1,gpgcheck=0,g)。
- 加上或修改 enabled=1 表示啟用 (%s,enabled=0,enabled=1,g)。
- 把 $releasever 取代為目前 RHEL 的版本 (%s,$releasever,5.6,g)。
- 執行 yum clean all。
- yum search drbd 便可以找到套件了。
