Openwrt编译进阶

摘要:这篇文章是Openwrt编译的学习笔记包括(1)Openwrt基础入门(2)Openwrt基础进阶(3)集成软件


之前总喜欢在在写文章之前写一大段自己的光荣事迹,后来发现看别人这样写的文章是一件很蛋疼的事,毕竟这是一篇技术类文章,不是小学生日记。
好吧,这次直接进入正题,抱歉,又写了一段和本文内容无关的文字……
去年学校开始用H3C认证来限制我们上网,于是好奇心再次害死猫,本宫终于修成正果,误入Openwrt这个大坑,折腾Openwrt有一年多了,到了回馈社会的时候了,这篇文章写写Openwrt编译的一些高级配置(相对入门级编译教程而言),以HG255D为例。


Openwrt基础编译

这类文章一手一大把,精简的,详细的(多半是废话)都有,这里就简单的把一些指令写下


编译环境为Ubuntu
#升级组件包
sudo apt-get update
#安装编译需要的组件
sudo apt-get install gcc g++ binutils patch bzip2 flex bison make autoconf gettext texinfo unzip sharutils subversion libncurses5-dev ncurses-term zlib1g-dev git-core gawk asciidoc libz-dev sphinxsearch libtool sphinx-common libssl-dev libsqlite3* intltool libiconv* gstreamer-0.10* glib2.0 libxml2-dev qemu
(*64位系统需安装ia32-libs)
#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源码
svn checkout svn://svn.openwrt.org/openwrt/trunk
#赋予trunk目录权限
sudo chmod -R 777 trunk
#进入trunk目录
cd trunk
#更新最新源码
./scripts/feeds update -a
#安装最新源码
./scripts/feeds install -a
#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
#编译
make V=99
#清除编译过程产生的临时文件
make clean
#恢复编译环境
make defconfig

Openwrt编译进阶

其实按照上面的指令一路执行下来,你已经能够在/bin/$target下找到刷机固件了,是不是很简单……

修改WIFI设置

package/kernel/mac80211/files/lib/wifi/mac80211.sh

config wifi-device  radio$devidx
    option type     mac80211
    option channel  11
    option hwmode   11ng
    option path '10180000.wmac'
    option htmode   HT20
    list ht_capab   GF
    list ht_capab   SHORT-GI-20
    list ht_capab   SHORT-GI-40
    list ht_capab   TX-STBC
    list ht_capab   RX-STBC12
    # REMOVE THIS LINE TO ENABLE WIFI:
    option disabled 0
    option noscan 1
    option txpower 20
    option htmode HT40-

config wifi-iface
    option device   radio$devidx
    option network  lan

修改LUCI界面配置

feeds/luci/modules/base/root/etc/config/luci

config core main
    option resourcebase '/luci-static/resources'
    #设置默认语言
    option lang 'zh_cn'
    #设置默认主题
    option mediaurlbase '/luci-static/bootstrap'

function index()
+   entry({"admin", "Free_Memory"}, call("Free_Memory"), _("释放内存"), 75)
end

function Free_Memory()
    luci.util.exec("echo 3 > /proc/sys/vm/drop_caches")
    luci.http.redirect(luci.dispatcher.build_url("admin", "status", "overview"))
end

在顶栏显示重启

feeds/luci/modules/admin-full/luasrc/controller/admin/system.lua

function index()
    entry({"admin", "reboot"}, call("action_reboot"), _("Reboot"), 90)
end

feeds/luci/modules/admin-full/luasrc/view/admin_system/reboot.htm

<%:Perform reboot%>

function index()
    entry({"admin", "flashops"}, call("action_flashops"), _("Backup / Flash Firmware"), 70)
end

修改配置文件

package/base-files/files/etc/
在这个目录里,你可以把你的备份的路由器导入进来

修改root密码

package/base-files/files/etc/shadow

#默认情况下root是没有密码的,需设定密码才能开启ssh

集成软件

添加aria2,luci添加,web管理界面

aria2 http://sourceforge.net/projects/aria2/files/stable/

#aria2的依赖安装
sudo apt-get update 
sudo apt-get install autoconf automake libcppunit-dev autopoint openssl libtool sphinx-common sphinxsearch libgcrypt11-dev 
#下载aria2源码
cd dl
sudo apt-get install wget
wget http://sourceforge.net/projects/aria2/files/stable/aria2-1.18.7/aria2-1.18.7.tar.bz2
#获取md5码
md5sum aria2-1.18.7.tar.bz2
#添加luci-aria2

这里用的是南浦月的luci-app-aira2和webui-aria2
OpenWrt-Extra https://github.com/nanpuyue/openwrt-extra

在feeds.conf.default中添加`src-git extra git://github.com/nanpuyue/openwrt-extra.git`
./scripts/feeds update -a
./scripts/feeds install -a

在make menuconfig中选中aria2,luci-app-aira2和webui-aria2就可以了

添加将自己开发的程序

在package下建立一个文件夹,以自己的项目命名,里边包括一个files文件夹和一个Makefile文件

目录结构

├Makefile
├
│  ├
│  │  ├
│  │  │  └ccnu
│  │  ├
│  │  │  └ccnu
│  ├
│  │  ├
│  │  │  ├
│  │  │  │  ├
│  │  │  │  │  ├
│  │  │  │  │  │  └ccnu.lua
│  │  │  │  │  ├
│  │  │  │  │  │  ├
│  │  │  │  │  │  │  └ccnu.lua
│  │  ├
│  │  │  └ccnu

package/ccnu/Makefile

include $(TOPDIR)/rules.mk

PKG_NAME:=ccnu
PKG_VERSION:=2.0.1      
PKG_RELEASE:=1
PKG_BUILD_DIR := $(BUILD_DIR)/$(PKG_NAME)

include $(INCLUDE_DIR)/package.mk

define Package/ccnu
  SECTION:=utils
  CATEGORY:=Utilities
  SUBMENU:=H3C inode
  TITLE:= iNode Compatible Client for CCNU
  DEPENDS:=+libc +libgcc 
  MAINTAINER:= RiceLyn 
endef

define Package/ccnu/description
    iNode Compatible Client for CCNU
endef

define Build/Prepare
endef

define Build/Configure
endef

define Build/Compile
endef

define Package/ccnu/install
    $(CP) ./files/* $(1)/
endef

$(eval $(call BuildPackage,ccnu))

之后./scripts/feeds install -a,ccnu就会出现在Utilities -> H3C inode里啦
这里先做一个简单的程序,以后会写文章详细介绍。

添加自动挂载脚本

/package/base-files/files/etc/gotplug/block/30-block_mount

#!/bin/sh

#---------------------------------------------------------------------
# Filename:    30-block_mount
# Revision:    0.5.1
# Data:        Jul. 7, 2014
# Email:       [email protected]
# Contacts:    QQ/TM 389191 or mail address above
# Licensing:   General Public License v2
# Description: Created for automatic mount block devices on OpenWRT
# Usage:       Put this script into directory /etc/hotplug.d/block
#---------------------------------------------------------------------

## Global settings of auto-mount script ##

# Turn on|off auto-mount function for disk volumes
VOL_ENABLED=1  # <0|1  0-Disable, 1-Enable>

# Turn on|off auto-mount function for sawp partition  
SWAP_ENABLED=1  # <0|1  0-Disable, 1-Enable>

# Set which method you want to name the mounted volumes
USE_VLABEL=1  # <0|1  0-Use device name, 1-Use volume label>  Eg. /mnt/sda1 | /mnt/DataDisk
#
# Note that if you choose name mount point by volume label but the volume's label is empty,
# the volume will be named to 'volume_$PARTUUID', such as the /mnt/volume_31173116-01
# Also, if exist more than one device which have the same volume label, it will be renamed 
# as the original name + sequence number, such as the /mnt/DataDisk_n (n=1,2,3..9)

# Show filesystem type as the prefix of mount point, requires set USE_VLABEL=1
FSTYPE_IN_VLABEL=1  # <0|1  0-Disable, 1-Enable>  Eg. /mnt/[ntfs]-DataDisk

# Set access the mounted device with read-write or read-only permission
FS_READONLY=0  # <0|1  0-Read Write, 1-Read Only>

# Exclusion list of auto-mount function
# Allows mixing the device name, volume label and UUID, each item must be separated by space(s)
# Eg. EXCLUDE_LIST="sda1 DataDisk f32b2ea6-4d42-43a5-bcec-7d818a163d07" 
EXCLUDE_LIST=""  # Default: empty string

# Specify a directory for mounts
MOUNTS_PATH="/mnt"  # Default: /mnt , don't need include the trailing slash (/)

# Define the add-ons scripts directory for automatic execute
ADDSH_PATH="/etc/hotplug.d/user"  # Script naming rule: [0-9][0-9]-xxxxx, Eg. 20-backup-sdcard
