OpenWrt BarrierBreaker 14.07-rc3 手记

1 外置存储 - ExtRoot

1.1 USB HDD 分区

安装依赖和工具包:
opkg install kmod-usb-storage kmod-fs-ext4 libext2fs block-mount fdisk e2fsprogs

reboot
挂载 USB HDD ,使用 fdisk /dev/sda 分成两个数据区:
  1. 分区 /dev/sda1 大小 1G ,用于保存系统数据;
  2. 分区 /dev/sda2 为剩余大小,用于保存用户数据。
使用 ext4 文件系统格式化两个分区:

(USB HDD 大小超过 21G 时,对 dev/sda2 格式化操作才需要添加 -m 1 操作。)

mkfs.ext4 -L overlay /dev/sda1
mkfs.ext4 -b 4096 -L data -m 1 /dev/sda2

重置路由至初始(出厂)状态。

1.2 挂载 USB HDD

安装依赖包并启动 fstab :
opkg install kmod-usb-storage kmod-fs-ext4 libext2fs block-mount

/etc/init.d/fstab enable

检查分区 /dev/sda1 是否存在,若不存在,reboot 一次。

挂载系统分区 /dev/sda1 :
uci add fstab mount
uci set fstab.@mount[-1].enabled=1
uci set fstab.@mount[-1].target=/overlay
uci set fstab.@mount[-1].device=/dev/sda1
uci set fstab.@mount[-1].fstype=ext4
uci commit

mount -t ext4 /dev/sda1 /mnt
cp -ar /overlay/* /mnt/

reboot 之后,df -h 检查是否挂载成功。成功时命令输出结果应包含下行内容(忽略容量和使用占比):

/dev/sda1               975.9M    140.6M    768.1M  15% /overlay
挂载 swap 虚拟内存:

(一般为内存大小两倍。)

dd if=/dev/zero of=/swap bs=1M count=128
mkswap /swap

uci add fstab swap
uci set fstab.@swap[-1].enabled=1
uci set fstab.@swap[-1].device=/swap
uci commit
挂载数据分区 /dev/sda2 :
mkdir /home

uci add fstab mount
uci set fstab.@mount[-1].enabled=1
uci set fstab.@mount[-1].target=/home
uci set fstab.@mount[-1].device=/dev/sda2
uci set fstab.@mount[-1].fstype=ext4
uci commit
确认挂载成功:

reboot 之后,free 检查 swap 是否挂载成功。成功时命令输出结果应包含下行内容(忽略使用大小):

Swap:       131068            0       131068

df -h 检查数据分区是否挂载成功。成功时命令输出结果应包含下行内容(忽略容量和使用占比):

/dev/sda2               824.7G     72.1M    816.3G   0% /home
迁移 root 家目录:
cd /
chmod 0700 root
mv root home/
ln -s home/root

2 局域网优化 - DMZ + UPnP

2.1 LAN

调整 MTU :
uci set network.lan.mtu=1492
uci commit
调整网段(略)

2.2 WAN

调整为静态地址(192.168.1.234):
uci set network.wan.proto=static
uci set network.wan.ipaddr=192.168.1.234
uci set network.wan.netmask=255.255.255.0
uci set network.wan.gateway=192.168.1.1
uci set network.wan.dns=114.114.115.115
uci commit
调整 MTU :
uci set network.wan.mtu=1492
uci commit
生效:
/etc/init.d/network restart

2.3 配置 DMZ (需光猫高级管理员权限):

在光猫中配置 DMZ 主机至 192.168.1.234 。

2.4 配置 UPnP :

opkg install luci-app-upnp

/etc/init.d/miniupnpd enable
/etc/init.d/miniupnpd start

3 科学上网 - dnsmasq + ipset + shadowsocks

3.1 配置 shadowsocks-libev

想办法从 shadowsocks 官网 下载对应芯片的 OpenWRT 包。

安装:
opkg install shadowsocks-libev-polarssl_1.4.6_ar71xx.ipk
rm -f shadowsocks-libev-polarssl_1.4.6_ar71xx.ipk

sed -e 's/ss-local/ss-redir/' /etc/init.d/shadowsocks > shadowsocks
mv -f shadowsocks /etc/init.d/shadowsocks

/etc/init.d/shadowsocks enable
vi /etc/shadowsocks.json 配置后启动(本地端口 1080):
/etc/init.d/shadowsocks start

3.2 配置 dnsmasq-full

安装:
opkg install dnsmasq-full

mkdir /etc/dnsmasq.d
echo conf-dir=/etc/dnsmasq.d > /etc/dnsmasq.conf

cat > /etc/dnsmasq.d/ipset.shadowsocks.org <<END
server=/.shadowsocks.org/208.67.220.220#443
ipset=/.shadowsocks.org/shadow
END

3.3 配置 ipset

安装(其中 1080 为 shadowsocks 本地端口):
opkg install iptables-mod-nat-extra ipset

cat > /etc/rc.local <<END
/usr/sbin/ipset -N shadow iphash

exit 0
END
cat > /etc/firewall.user <<END
/usr/sbin/iptables -t nat -A prerouting_rule -p tcp -m set --match-set shadow dst -j REDIRECT --to-port 1080
END

sh /etc/rc.local
sh /etc/firewall.user

3.4 google.com (示例)

配置:
cat > /etc/dnsmasq.d/ipset.google.com <<END
server=/.google.com/208.67.220.220#443
server=/.google.com.hk/208.67.220.220#443

生效:
/etc/init.d/dnsmasq restart

4 网络存储 - lighttpd (WebDAV 暂无法实现)

4.1 替代 uhttpd

/etc/init.d/uhttpd disable
/etc/init.d/uhttpd stop

opkg install lighttpd-mod-cgi

mv /etc/lighttpd/lighttpd.conf /etc/lighttpd/lighttpd.conf.opkg

/etc/init.d/lighttpd enable
/etc/init.d/lighttpd start

4.2 支持 WebDAV

(Lighttpd 对 WebDAV 最新规范地实现度也不足 100% ,以后再找找有没有更好的办法…)

5 家庭多媒体共享 - minidlna + pure-ftpd

5.1 安装 minidlna

opkg install minidlna

mkdir -p /home/dlna/data
mkdir /home/dlna/db

uci set minidlna.config.db_dir=/home/dlna/db
uci set minidlna.config.log_dir=/home/dlna
uci delete minidlna.config.media_dir
uci add_list minidlna.config.media_dir=/home/dlna/data
uci commit

/etc/init.d/minidlna enable
/etc/init.d/minidlna start

5.2 安装 pure-ftpd

opkg install pure-ftpd

uci set pure-ftpd.@pure-ftpd[-1].chrooteveryone=0
uci set pure-ftpd.@pure-ftpd[-1].enabled=1
uci commit

/etc/init.d/pure-ftpd enable
/etc/init.d/pure-ftpd start

6 脱机下载 - aria2

6.1 安装 aria2

官方源中的版本阉割掉了 BitTorrent 下载功能 :-( 所以得从 南浦月 的帖子 《luci-app-aria2、yaaw、aria2-1.18.3下载》 下载相应芯片的包。

(BT 下载速度非常差,原因有待深入研究…)

opkg install aria2_1.18.3-1_ar71xx.ipk

6.2 安装 WebUI

yaaw 项目官网 下载 zip 包并上传至路由器。

opkg install unzip

cd /home/aria
mv /root/yaaw-master.zip .
unzip yaaw-master.zip
rm -f yaaw-master.zip
mv yaaw-master webui
cd /www
ln -s /home/aria/webui aria

9 远程控制 - DDNS

9.1 3322

配置计划任务(USER、PASSWORD、DOMAIN 自填):
echo "* * * * * /usr/bin/wget -qO - 'http://<USER>:<PASSWORD>@members.3322.net/dyndns/update?hostname=<DOMAIN>' > /dev/null 2>&1" > /etc/crontabs/root

9.2 外部 SSH 访问

uci add firewall rule
uci set firewall.@rule[-1].name=Allow-SSH

uci set firewall.@rule[-1].src=wan
uci set firewall.@rule[-1].dest_port=22
uci set firewall.@rule[-1].target=ACCEPT

9.3 外部 HTTP 访问

(光猫会占很不智能地占用 80 端口…所以采用 86 端口。)

echo '/usr/sbin/iptables -t nat -A prerouting_rule -p tcp -d 192.168.1.234 --dport 86 -j REDIRECT --to-port 80' >> /etc/firewall.user

uci add firewall rule
