CentOS6.5 将安装光盘作为yum源

2021-03-05 17:02:36 作者：互联网

前言

网上找适合CentOS6.5的yum源很困难了
替代方案，将安装光盘作为yum源
我用的是VMware虚拟机。嗯，虚拟机还可以挂光盘，那要是云主机呢？可以考虑将文件拷贝到云主机的某个目录，将该目录作为yum源。
CentOS6.5 CD： CentOS-6.5-x86_64-bin-DVD1.iso

基本步骤

VMware虚拟机已经添加好光驱，光驱中放上CentOS6.5安装盘。
mount命令查看是否已经挂接了光驱。如果已挂接，直接看
未挂接是这样的：

 shell> mount
/dev/mapper/VolGroup-lv_root on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

已挂接是这样的：

shell> mount
/dev/mapper/VolGroup-lv_root on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sr0 on /mnt/cdrom type iso9660 (ro)

创建光驱挂载点

shell> mkdir /mnt/cdrom

挂载光驱

shell> mount  /dev/sr0  /mnt/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
shell> mount
/dev/mapper/VolGroup-lv_root on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sr0 on /mnt/cdrom type iso9660 (ro)

配置yum源
先备份

shell> cd /etc/yum.repos.d/
shell> mv CentOS-Base.repo CentOS-Base.repo.backup
shell> mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.backup
shell> mv CentOS-Vault.repo CentOS-Vault.repo.backup
shell> cp CentOS-Media.repo CentOS-Media.repo.backup
shell> ls
CentOS-Base.repo.backup       CentOS-Media.repo         CentOS-Vault.repo.backup
CentOS-Debuginfo.repo.backup  CentOS-Media.repo.backup

再修改

shell> vi /etc/yum.repos.d/CentOS-Media.repo
----------------------------
[c6-media]
name=CentOS-$releasever - Media
# 挂载的光盘路径
baseurl=file:///mnt/cdrom/
gpgcheck=1
# 启用此yum源
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

检查yum源

shell> yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
repo id                                      repo name                                             status
c6-media                                     CentOS-6 - Media                                      6,364+3
repolist: 6,364

查看yum源中是否有wget
