rhel 5 yum光盘源（rhel7系统启动的第一个进程是）

该方法使用红帽企业版5.x系列（4.X的直接用好像是不行的）：os :

LSB Version:    :core-4.0-ia32:core-4.0-noarch:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-ia32:printing-4.0-noarch

Distributor ID: RedHatEnterpriseServer

Description:    Red Hat Enterprise Linux Server release

5.6

(Tikanga)

Release:        5.6

Codename:       Tikanga

1、首先插入光盘，挂载光驱到/mnt

[root@agent ~]#

mount  /dev/cdrom /mnt

mount: block device /dev/cdrom is write-protected, mounting read-only

2、到/etc/yum.repos.d/下面编辑yum源头文件（* 改文件名任意，但是必须以.repo作为后缀）[root@agent ~]# cd  /etc/yum.repos.d[root@agent yum.repos.d]# pwd/etc/yum.repos.d[root@agent yum.repos.d]#ls -lhtotal 4-rw-r--r-- 1 root root 741 Nov 13 17:16 rhel-debuginfo.repo[root@agent yum.repos.d]# vi rhel-debuginfo.repo[Cluster]name=Red Hat Enterprise Linux $releasever - $basearch - Clusterbaseurl=file:///mnt/Clusterenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release[ClusterStorage]name=Red Hat Enterprise Linux $releasever - $basearch - ClusterStoragebaseurl=file:///mnt/ClusterStorageenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release[Server]name=Red Hat Enterprise Linux $releasever - $basearch - Serverbaseurl=file:///mnt/Serverenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release[VT]name=Red Hat Enterprise Linux $releasever - $basearch - VTbaseurl=file:///mnt/VTenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release3、制作完yum文件以后，预先清空以前可能存在的 cache, 然后根据当前的yum文件(

rhel-debuginfo.repo)重新制作cache.[root@agent mnt]# yum clean allLoaded plugins: rhnplugin, securityCleaning up Everything[root@agent mnt]# yum makecache4、这样以后就可以使用本地光盘yum源了比如使用yum安装mysql:[root@agent mnt]# yum install mysqlLoaded plugins: rhnplugin, securityThis system is not registered with RHN.RHN support will be disabled.Setting up Install ProcessResolving Dependencies--> Running transaction check---> Package mysql.i386 0:5.0.77-4.el5_5.4 set to be updated--> Finished Dependency ResolutionDependencies Resolved============================================================================================================================= Package                   Arch                     Version                                 Repository                  Size=============================================================================================================================Installing: mysql                     i386                     5.0.77-4.el5_5.4                        Server                     4.8 MTransaction Summary=============================================================================================================================Install       1 Package(s)Upgrade       0 Package(s)Total download size: 4.8 MIs this ok [y/N]: y
