最终功能:
无线路由器的主要功能,网口 WAN 接入,USB 无线网卡 AP 热点输出,连上 wifi 之后跳转到认证页面,点击认证方可上网,有效时间 10 分钟,认证成功之后自动访问指定网址。
硬件准备:
1.Raspberry Pi 2 model B
2.USB 无线网卡,我使用的是 TL-WN722N 150Mbps 芯片是 AR9271
3. 操作系统:CentOS 7
4.SD 卡 8GB
开始之前最好配置好代理,因为编译过程中所有的依赖会联网自动下载,会有大部分时间耗在这里,如果速度慢或者被墙……
配置编译环境(一定要非 root 账户):
# 升级组件
sudo yum update
# 安装编译组件
sudo yum install libtool autoconf automake gcc-multilib bison screen gcc g++ binutils patch bzip2 flex make gettext unzip libc6 git-core git build-essential libncurses5-dev zlib1g-dev gawk quilt asciidoc libz-dev subversion
下载 openwrt 源码(新手不建议下载 trunk,不是很稳定)
# 使用非 root 用户登录,建立 openwrt 目录
mkdir openwrt
# 进入 openwrt 目录
cd openwrt
# 下载 openwrt 的源码
git clone git://git.openwrt.org/15.05/openwrt.git
集成 nodogsplash 在 /openwrt/feeds.conf.default 中添加
src-git nodogsplash https://github.com/nodogsplash/nodogsplash.git
设置权限
sudo chmod -R 777 trunk
cd trunk
更新并安装
./scripts/feeds update -a
./scripts/feeds install -a
根据自己的需要更改系统默认设置,就不细说了,这里列举几个我的设置

# Your router may have several interfaces, and you
# probably want to keep them private from the network/gatewayinterface.
# If so, you should block the entire subnets on those interfaces, e.g.:
#list authenticated_users ‘block to 192.168.0.0/16’
list authenticated_users ‘block to 10.0.0.0/8’
# Typical ports you will probably want to open up.
list authenticated_users ‘allow tcp port 22’
list authenticated_users ‘allow tcp port 53’
list authenticated_users ‘allow udp port 53’
list authenticated_users ‘allow tcp port 80’
list authenticated_users ‘allow tcp port 443’
list authenticated_users ‘allow tcp port 8080’
# For preauthenticated users to resolve IP addresses in their
# initial request not using the router itself as a DNS server,
list preauthenticated_users ‘allow tcp port 53’
list preauthenticated_users ‘allow udp port 53’
#list preauthenticated_users ‘allow tcp port 8080’
# Allow ports for SSH/Telnet/DNS/DHCP/HTTP/HTTPS
list users_to_router ‘allow tcp port 22’

编译配置
# 更新版本号
svn up
# 进入编译菜单
make menuconfig
Y:选择 Y,该软件将被编译,并且加入到你的目标固件里;
M:选择 M,该软件包将会被编译,但不会被放入固件里。在需要它的时候,可以用 OPKG 软件包管理器进行安装;
N:选择 N,该软件包将不会被编译,也不会被安装进固件。
方向键是移动光标
回车键是确认
空格键是选择,可以代替 Y /M/ N 键的使用
/: 搜索
Target System 选择 brcm2708-bcm2709 按 Y 选中
需要集成的软件
