完成后 , 会自动启用 SSH 服务 , 使用 ssh [email protected] 登陆

重新启动

reboot && exit

cd /tmp
wget http://downloads.openwrt.org/snapshots/trunk/PLATFORM/xxx-sysupgrade.bin
sysupgrade -v /tmp/openwrt-ar71xx-generic-wzr-hp-ag300h-squashfs-sysupgrade.bin

安装软件

使用 ssh [email protected] 登陆

更新软件源

opkg update

安装 Web 管理界面

opkg install luci

重新启动

reboot && exit

配置

修改网络参数

vi /etc/config/network

config interface 'lan'
option ifname 'eth1'
option type 'bridge'
option proto 'static'
option ipaddr '10.1.2.1'            #WR720N的地址
option netmask '255.255.255.0'
option ip6assign '60'

vi /etc/config/wireless

config wifi-device  radio0
    option type     mac80211
    option channel  11
    option hwmode   11ng
    option path 'platform/ar933x_wmac'
    option htmode   HT20
    list ht_capab   SHORT-GI-20
    list ht_capab   SHORT-GI-40
    list ht_capab   RX-STBC1
    list ht_capab   DSSS_CCK-40
    # REMOVE THIS LINE TO ENABLE WIFI:
    # option disabled 1             #将该行注释 , 启用WIFI

config wifi-iface
    option device 'radio0'
    option network 'lan'
    option mode 'ap'
    option ssid '[email protected]'    #SSID 名称
    option encryption 'psk-mixed'   #加密方法
    option key '[email protected]'    #密码

Boot from usb 

opkg update
opkg install kmod-usb-core kmod-usb-uhci kmod-usb-storage  kmod-usb2  kmod-fs-ext3

*

mount /dev/sda1 /mnt

*

tar -C /overlay -cvf - . | tar -C /mnt -xf -

/etc/config/fstab

config 'global'
    option  anon_swap       '0'
    option  anon_mount      '0'
    option  auto_swap       '1'
    option  auto_mount      '1'
    option  delay_root      '5'
    option  check_fs        '0'

config 'mount'
    option  target  '/mnt'
    option  uuid    'ced46a51-951a-4d22-be2a-b7cebbd66d44'
    option  enabled '1'
    option fstype   ext4
    option options  rw,sync
    option enabled_fsck 1
    option is_rootfs 1

Expanding the filesystem 

~$ opkg update
~$ opkg install fdisk resize2fs

~$ fdisk /dev/mmcblk0
  1. Press p to print out the partition table, 记下分区的起始扇区号
  2. Press d to delete the main partition
  3. Press n to re-create partition, 起始扇区填写前面打印的起始扇区号，会提示检测到 ext4 签名，询问是否移除，选择 「No」。
  4. Press w to write the partition table
  5. Press q to quit

这样操作下来原有的分区结束为止就被修改为最大值了，保留分区签名 数据就不会丢失了，现在我们 reboot 重启，做 fsck 检查，修复 ext4 数据。

e2fsck -f /dev/mmcblk0p1

resize2fs /dev/mmcblk0p1

然后我们看下系统的磁盘容量

root at nanopi-r2s in ~
$ df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root                14.6G     76.3M     14.5G   1% /
tmpfs                   494.1M    100.0K    494.0M   0% /tmp
tmpfs                   512.0K         0    512.0K   0% /dev

至此，系统扩容工作已经完成了。
