RHEL 5.7 Yum配置本地源[Errno 2] No such file or directory

在Red Hat Enterprise Linux Server release 5.7 上配置YUM本地源時，遇到了"Errno 5] OSError: [Errno 2] No such file or directory xxxx",花了點時間搞清楚錯誤的來龍去脈。特此記錄一下： 將Redhat 5.7的光盤鏡像拷貝到了/mnt/cdrom/LinuxSrc目錄下，配置了rhel-media.repo文件，如下所示

[root@DB-Server yum.repos.d]# more rhel-media.repo 
[media]
name=Red Hat Enterprise Linux 5.7                                
baseurl=file:///mnt/cdrom/LinuxSrc                                         
enabled=1                                                         
gpgcheck=0                                                        
gpgkey=file:///mnt/cdrom/LinuxSrc/RPM-GPG-KEY-redhat-release 

執行yum clean all命令後，執行yum makecache遇到了下面錯誤：

[root@DB-Server yum.repos.d]# yum clean all

Error: Cannot retrieve repository metadata (repomd.xml) for repository: media. Please verify its path and try again
[root@DB-Server yum.repos.d]# 
clip_image001

出現這個錯誤的根本原因在於RHEL 5.x 版本與RHEL 6.x 版本的rpm包存放路徑不同： RHEL 5.x : ../Server 例如：我案例環境位於/mnt/cdrom/LinuxSrc/Server 下。 RHEL 6.x : ../Packages 所以還在於上面的baseurl參數設置錯誤。那麼我們可以通過兩種方法解決這個問題： 方法1：配置正確的baseurl參數。

[root@DB-Server yum.repos.d]# vi rhel-media.repo 
[media]
name=Red Hat Enterprise Linux 5.7
baseurl=file:///mnt/cdrom/LinuxSrc/Server
enabled=1
gpgcheck=0
gpgkey=file:///mnt/cdrom/LinuxSrc/RPM-GPG-KEY-redhat-release
clip_image002

方法2：使用createrepo命令創建本地源目錄，將其指向baseurl指定的目錄

 [root@DB-Server Server]# rpm -ivh createrepo-0.4.11-3.el5.noarch.rpm
