熟練linux光盤(pán)的安裝
訪(fǎng)問(wèn)光盤(pán)的數(shù)據(jù)
實(shí)驗(yàn)步驟
?[root@localhost ~]# umount /dev/cdrom
[root@localhost ~]# ls /media/
[root@localhost~]#
二．手動(dòng)掛載
??? 1.指定光盤(pán)安裝位置
[root@localhost~]# mount /dev/cdrom /media/
mount:block device /dev/cdrom is write-protected, mounting read-only
?
2.測(cè)試
[root@localhost~]# mount | grep hdc
/dev/hdcon /media/RHEL_5.9 x86_64 DVD type iso9660 (ro,nosuid,nodev,uid=0)
/dev/hdcon /media type iso9660 (ro)
結(jié)果驗(yàn)證
[root@localhost~]# ls /media/
