RedHat服务器上[Errno 5] OSError: [Errno 2]的解决方法
	在Red Hat Enterprise Linux Server release 5.7 上配置YUM本地源时,遇到了"[Errno 5] OSError: [Errno 2] No such file or directory xxxx",花了点时间搞清楚错误的来龙去脉。特此记录一下: 
	
	将Redhat 5.7的光盘镜像拷贝到了/mnt/cdrom/LinuxSrc目录下,配置了rhel-media.repo文件,如下所示
	 
复制代码
代码如下:
	
	[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
	  
	执行yum clean all命令后,执行yum makecache遇到了下面错误:
	 
复制代码
代码如下:
	
	[root@DB-Server yum.repos.d]# yum clean all
	Loaded plugins: product-id, security, subscription-manager

	出现这个错误的根本原因在于RHEL 5.x 版本与RHEL 6.x 版本的rpm包存放路径不同: 
	
	RHEL 5.x : ../Server    例如:我案例环境位于/mnt/cdrom/LinuxSrc/Server 下。 
	
	RHEL 6.x : ../Packages 
	
	所以还在于上面的baseurl参数设置错误。那么我们可以通过两种方法解决这个问题: 
	
	  
	
	方法1:配置正确的baseurl参数。
	 
复制代码
代码如下:
	
	[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

	方法2:使用createrepo命令创建本地源目录,将其指向baseurl指定的目录 
	 
复制代码
代码如下:
	
	[root@DB-Server Server]# rpm -ivh createrepo-0.4.11-3.el5.noarch.rpm
