在Linux主机中使用YUM工具在线安装、更新软件时，往往会因网速不稳定或者中途网络中断而导致无法正常升级或安装软件，而搭建本地YUM源就无需为此而苦恼，因为其资源就存放在本地，而不受Internet的网络限制，从而可以提升局域网内更新软件的效率
一、首先挂在光盘镜像
[[email protected] /]# mkdir /mnt/cdrom [[email protected] /]# mount -r /dev/cdrom /mnt/cdrom [[email protected] /]# mount /dev/mapper/vg0-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) /dev/sda1 on /boot type ext4 (rw) /dev/mapper/vg0-usr on /usr type ext4 (rw) /dev/mapper/vg0-var on /var type ext4 (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) /dev/sr0 on /mnt/cdrom type iso9660 (ro) [[email protected] /]#
二、创建本地目录/yum ，然后将光盘内的文件复制到此目录
[[email protected] /]# mkdir /yum [[email protected] /]# cp -R /mnt/cdrom/* /yum [[email protected] yum]# ls /yum CentOS_BuildTag isolinux RPM-GPG-KEY-CentOS-Debug-6 EFI Packages RPM-GPG-KEY-CentOS-Security-6 EULA RELEASE-NOTES-en-US.html RPM-GPG-KEY-CentOS-Testing-6 GPL repodata TRANS.TBL images RPM-GPG-KEY-CentOS-6
三、新建yum repo配置文件
---------repo文件详解---------------------------
[repositoryid]
# 对于当前系统的yum来讲，此repositoryid用于惟一标识此repository指向，因此，其必须惟一；
name=
# 当前仓库描述信息；
baseurl=url://path/to/repository/
# 指明repository的访问路径；通常为一个文件服务器上输出的某repository；
url:
ftp服务
ftp://SERVER/PATH/TO/REPOSITORY
http服务
http://SERVER/PATH/TO/REPOSITORY
本地目录：
file:///PATH/TO/REPOSTIROY
enabled={1|0}
此仓库是否可被使用
gpgcheck={1|0}
是否对程序包做校验
gpgkey=url://path/to/keyfile
指明gpgkey文件路径；
cost=#
指明当前repository的访问开销，默认为1000；
-------------------------------------
[[email protected] /]# vim /etc/yum.repos.d/CD-Local.repo [CD-Local] name=CentOS 6.6 X86_64 on dvd1 baseurl=file:///yum gpgcheck=0 enabled=1 ~
四、清除并删除记录，然后查看 yum 源的配置
清除记录
[[email protected] /]# yum clean all Loaded plugins: fastestmirror, refresh-packagekit, security Cleaning repos: CD-Local Cleaning up Everything Cleaning up list of fastest mirrors
删除就记录
[[email protected] /]# rm -rf /var/cache/yum/* [[email protected] /]#
查看yum 配置
[[email protected] yum]# yum repolist Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile repo id repo name status CD-Local CentOS 6.6 X86_64 on dvd1 6,518 repolist: 6,518
至此 我们的本地yum源已经搭建完毕，
五、为了验证我们使用发行光盘制作的yum源可用，接下来我们使用我们本地搭建的yum 源安装zsh软件
1、首先我们查看本机是否已经安装了zsh软件
[[email protected] /]# rpm -qa zsh [[email protected] /]#
发现并没有安装
2、使用本地搭建的yum源安装zsh
[[email protected] /]# yum install zsh Loaded plugins: fastestmirror, refresh-packagekit, security Setting up Install Process Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package zsh.x86_64 0:4.3.10-7.el6 will be installed --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================================================== Package Arch Version Repository Size ==================================================================================================================================== Installing: zsh x86_64 4.3.10-7.el6 CD-Local 2.1 M Transaction Summary ==================================================================================================================================== Install 1 Package(s) Total download size: 2.1 M Installed size: 4.8 M Is this ok [y/N]: y //输入Y 确认安装 Downloading Packages: Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : zsh-4.3.10-7.el6.x86_64 1/1 Verifying : zsh-4.3.10-7.el6.x86_64 1/1 Installed: zsh.x86_64 0:4.3.10-7.el6 Complete!
显示已将安装完毕
验证是否安装完毕：
[[email protected] yum]# cat /etc/shells /bin/sh /bin/bash /sbin/nologin /bin/dash /bin/tcsh /bin/csh /bin/zsh [[email protected] /]# rpm -qa zsh zsh-4.3.10-7.el6.x86_64 [[email protected] /]#
OK 至此 我们使用发行光盘创建的本地yum源已经搭建完毕
