linux下搭建本地yum源

1.首先让镜像被系统识别

[root@localhost Desktop]# df //首先查看已存在的挂载项 Filesystem 1K-blocks Used Available Use% Mounted on /dev/vda1 10473900 6971760 3502140 67% / devtmpfs 469332 0 469332 0% /dev tmpfs 484920 140 484780 1% /dev/shm tmpfs 484920 12784 472136 3% /run tmpfs 484920 0 484920 0% /sys/fs/cgroup /dev/mapper/vg0-vo 483670 2339 451840 1% /home 

现在我把镜像挂载到/mnt目录上

[root@localhost Desktop]# mount -t iso9660 -o loop /dev/cdrom /mnt/cdrom //镜像挂载到/mnt目录上 mount: /dev/loop0 is write-protected, mounting read-only [root@localhost Desktop]# df Filesystem 1K-blocks Used Available Use% Mounted on ... /dev/loop0 3654720 3654720 0 100% /mnt //挂载镜像成功 

2.查看/mnt下的镜像文件

[root@localhost Desktop]# cd /mnt [root@localhost mnt]# ls addons images Packages RPM-GPG-KEY-redhat-release EFI isolinux release-notes TRANS.TBL EULA LiveOS repodata GPL media.repo RPM-GPG-KEY-redhat-beta 

有这些文件说明挂载成功了。

3.配置本地yum源

[root@localhost etc]# cd /etc/yum.repos.d/ [root@localhost etc]#rm -rf * [root@localhost yum.repos.d]# vim yum.repo //文件名称一定以.repo为后缀 [rhel7.0] //仓库描述 name=rhel7.0 server //对软件源的描述 baseurl=file:///mnt //镜像的挂载入地址 file:// --格式 /mnt--指定目录 gpgcheck=0 //不检查gpgkey enabled=1 //此yum源语句块立即生效 

4.测试

[root@localhost yum.repos.d]# yum clear all //清空之前的yum源信息 Loaded plugins: langpacks No such command: clear. Please use /usr/bin/yum --help [root@localhost yum.repos.d]# yum repolist //列出yum的信息 Loaded plugins: langpacks repo id repo name status rhel7.0 rhel7.0 server 4,305 repolist: 4,305 [root@localhost yum.repos.d]# yum install gcc -y //下载gcc 

5.设置开机自动挂载

系统reboot后，镜像不会自动挂载到/mnt目录上,我们需要修改系统启动文件。

[root@localhost Desktop]# vim /etc/rc.d/rc.local 最后一行添加 mount /root/Desktop/rhel-server-7.0-x86_64-dvd.iso /mnt //mount 镜像的绝对路径 要挂载的目录 [root@localhost Desktop]# chmod 755 /etc/rc.d/rc.local //系统开机时自动执行此脚本 

测试

[root@localhost Desktop]# reboot
[root@foundation36 kiosk]# ssh 172.25.254.136
root@172.25.254.136's password: Last login: Thu Jan 17 22:50:16 2019 from 172.25.254.36 [root@localhost ~]# df Filesystem 1K-blocks Used Available Use% Mounted on ... /dev/loop0 3654720 3654720 0 100% /mnt //开机被自动挂载上
