rhel 或 CentOS配置本地yum源
已在CentOS 、Redhat 5.5、6.5和7.8上测试通过。
挂载ISO文件
直接在外部系统挂载iso镜像文件
一般在iso文件挂载后，在OS内部为/dev/sr0或 /dev/cdrom 或 /dev/hdc(5.5版本)，若没有这几个文件，则可能需要重启OS来挂载光盘：
1 2 3 4 5 | [root@lhrdocker ~]# ll /dev/sr0 brw-rw----+ 1 root cdrom 11, 0 Dec 3 14:37 /dev/sr0 [root@lhrdocker ~]# ll /dev/cdrom lrwxrwxrwx 1 root root 3 Dec 3 14:37 /dev/cdrom -> sr0 [root@lhrdocker ~] |
在OS内部挂载iso文件
在该情况下，可以将iso文件整体上传到OS内部某个文件夹下，然后在OS内部挂载该iso文件。
1 2 3 4 5 6 | -- 直接使用mont命令进行挂载即可解压 mkdir -p /media/lhr/cdrom mount -t iso9660 -o loop CentOS-7-x86_64-Minimal-2009.iso /media/lhr/cdrom/ -- 或者直接mount mount CentOS-7-x86_64-Minimal-2009.iso /media/lhr/cdrom/ |
