第一步，添加内核相关支持

编译openwrt支持USB自动mount功能

make menuconfig
1). 添加USB相关支持
Kernel modules —> USB Support —> <*> kmod-usb-core.  
Kernel modules —> USB Support —> <*> kmod-usb-ohci.  
Kernel modules —> USB Support —> <*> kmod-usb-uhci.  
Kernel modules —> USB Support —> <*> kmod-usb-storage.
Kernel modules —> USB Support —> <*> kmod-usb-storage-extras.
Kernel modules —> USB Support —> <*> kmod-usb2.  

2). 添加SCSI支持
Kernel modules —> Block Devices —> <*>kmod-scsi-core

3). 添加USB挂载
Base system —> <*>block-mount

4). 添加自动挂载工具
Utilities —> Filesystem —> <*> badblocks

5). 添加文件系统支持
Kernel modules —> Filesystems —> <*> kmod-fs-ext4
Kernel modules —> Filesystems —> <*> kmod-fs-vfat
Kernel modules —> Filesystems —> <*> kmod-fs-ntfs


6). 添加UTF8编码,CP437编码，ISO8859-1编码
Kernel modules —> Native Language Support —> <*> kmod-nls-cp437
Kernel modules —> Native Language Support —> <*> kmod-nls-iso8859-1
Kernel modules —> Native Language Support —> <*> kmod-nls-utf8

Utilities  ---> disc ---> <*> fdisk.................................... manipulate disk partition table

Utilities  ---> <*> usbutils................................... USB devices listing utilities

第二步，开机自动挂载

df一下应该就可以看到挂载的USB硬盘了

下面写一个启动脚本，让路由器在启动时自动挂载USB硬盘。

vim /etc/init.d/usbdisk

写入脚本:

#!/bin/sh /etc/rc.common 
START=99 
STOP=10 
start() { 
mount -t ext3 -o noatime /dev/scsi/host0/bus0/target0/lun0/part1 /mnt 
} 
stop() 
{ 
sync 
umount /dev/scsi/host0/bus0/target0/lun0/part1 
}
restart() 
{ 
stop
start 
}

加入可执行权限

chmod 755 /etc/init.d/usbdisk

加入到启动目录

ln -s /etc/init.d/usbdisk /etc/rc.d/S99usbdisk

第三步，热插拔支持


自动挂载脚本,在/etc/hotplug.d/block/创建一个30-usbmount的文件,#!/bin/sh  case "$ACTION" in         add)                for i in $(ls /dev/ | grep ‘sd[a-z][1-9]‘)                   do                       mkdir -p /mnt/$i                       mount  -o iocharset=utf8,rw /dev/$i /mnt/$i                        if [ "$?" -ne 0 ];then                            mount -o rw /dev/$i /mnt/$i                        fi                  done              ;;      remove)                     MOUNT=`mount | grep -o ‘/mnt/sd[a-z][1-9]‘`                     for i in $MOUNT                     do                      umount $i                   done              ;;
  esac
