centos配置yum源

UUID=afb69863-b1d5-45bc-8a67-30cf8f38769c /boot ext4 defaults 1 2

rhel-source/primary_db | 3.1 MB 00:00 ...
rhel-source/other_db | 1.6 MB 00:00 ...
[root@test /]# mount /dev/sr0 /mnt -t iso9660
mount: block device /dev/sr0 is write-protected, mounting read-only
(3)继续使用mount命令，查看是否挂载成功
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)

(8)创建yum缓存
命令：yum makecache
[root@test yum.repos.d]# yum makecache
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
rhel-source | 3.9 kB 00:00 ...

1.用yum源安装rpm安装包命令：
yum install xxx.rpm
2.配置本地yum源
(1)列出Linux系统里的所有挂载点 mount
[root@test /]# mount
/dev/mapper/vg_test-lv_root on / type ext4 (rw)
sysfs /sys sysfs defaults 0 0
roc /proc proc defaults 0 0
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")
packagekit-media.repo rhel-source.repo
[root@test yum.repos.d]# vim rhel-source.repo
[rhel-source]
name=Red Hat Enterprise Linux $releasever - $basearch - Source
[root@test /]# mount
/dev/mapper/vg_test-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 /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
/dev/sr0 on /mnt type iso9660 (ro) --挂载成功--
(4)配置启动自动挂载光盘镜像 vim /etc/fstab 插入一下内容，保存退出，重启生效
/dev/sr0 /mnt iso9660 defaults,ro 0 0
/dev/sr0 /mnt iso9660 defaults,ro 0 0
(5)配置yum源文件
[root@test /]# cd /etc/yum.repos.d/
[root@test yum.repos.d]# ls
gvfs-fuse-daemon on /root/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev)
/dev/sr0 on /media/RHEL_6.5 x86_64 Disc 1 type iso9660 (ro,nosuid,nodev,uhelper=udisks,uid=0,gid=0,iocharset=utf8,mode=0400,dmode=0500)
/dev/sr0 on /media/RHEL_6.5 x86_64 Disc 1 type iso9660 (ro,nosuid,nodev,uhelper=udisks,uid=0,gid=0,iocharset=utf8,mode=0400,dmode=0500)
(2)将光盘镜像挂载到/mnt下 mount /dev/sr0 /mnt -t iso9660
[root@test /]# vim /etc/fstab
# /etc/fstab
# Created by anaconda on Tue Jun 5 18:40:48 2018
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
/dev/sda1 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
gvfs-fuse-daemon on /root/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev)

(7)清楚yum源缓存
命令：yum clean all
[root@test yum.repos.d]# yum clean all
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/mapper/vg_test-lv_root / ext4 defaults 1 1
baseurl=file:///mnt
enabled=1
gpgcheck=1
(6)导入yum源的key
命令格式：rpm --import /mnt/RPM-GPG-KEY*
[root@test yum.repos.d]# rpm --import /mnt/RPM-GPG-KEY-redhat-*
Metadata Cache Created
[root@test yum.repos.d]#
(9)列出所有缓存生成的rpm包
命令：yum list
[root@test yum.repos.d]# yum list
... --内容这里省略--
