linux mount使用和rpm包安装

[root@localhost ~]# mount
/dev/sda1 on / type ext3 (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)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
none on /proc/fs/vmblock/mountPoint type vmblock (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/dev/hdc on /media/RHEL_5.4 i386 DVD type iso9660 (ro,noexec,nosuid,nodev,uid=0)    这个就是光盘的挂载点了

[root@localhost ~]# mkdir /cdyum==》新建文件夹，用于挂载
[root@localhost ~]# mount /dev/hdc /cdyum/==》挂载到刚刚建好的文件夹里
mount: block device /dev/hdc is write-protected, mounting read-only
[root@localhost ~]# mount==》查看挂载信息
/dev/sda1 on / type ext3 (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)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
none on /proc/fs/vmblock/mountPoint type vmblock (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/dev/hdc on /media/RHEL_5.4 i386 DVD type iso9660 (ro,noexec,nosuid,nodev,uid=0)
/dev/hdc on /cdyum type iso9660 (ro)       ==》这个就是我们手动挂载的目录

之后就可以cd到/cdyum 目录进package中 rpm -ivh vsftpd-...包
rpm -qa | grep vsftpd查看 vsftpd是否被安装；

也可以rpm -e vsftpd卸载 vsftpd软件包

service vsftpd status  或者start启动

umount /cdyum
