Openwrt编译进阶

Openwrt 星雨 1179℃ 0评论

(1)-编译703_8M固件

1. target/linux/ar71xx/image/Makefile
$(eval $(call SingleProfile,TPLINK-LZMA,$(fs_64kraw),TLWR703,tl-wr703n-v1,TL-WR703N,ttyATH0,115200,0×07030101,1,8Mlzma))

2. tools/firmware-utils/src/mktplinkfw.c
.id = “TL-WR703Nv1″,

.hw_id = HWID_TL_WR703N_V1,

.hw_rev = 1,

.layout_id = “4Mlzma”,

将其中的4Mlzma替换成8Mlzma

(2)-修改默认WIFI,添加WIFI配置,WIFI名为MAC后六位

修改package/kernel/mac80211/files/lib/wifi/mac80211.sh
option disabled 1改成0,默认开启wifi。
option disabled 0下添加
option htmode HT40+

option channel 1

option country CN

option noscan 1

option txpower 17

option htmode HT40+ 使用40MHz频宽,但只支持1-7信道。HT40-,支持5-13信道。HT20 支持1-13信道,20MHz频宽
option channel 1使用信道1,1-13之间。若有限定频宽,信道参考如上。
option country CN 设定wifi标准为中国 CN、JP、HK均可开启13信道,默认的US只有1-12信道
option noscan 1 强制使用40MHz的频宽
option txpower 17 发射功率为17dBm,大约50mW。不可设定过大,否则有烧毁PA的危险。

修改默认SSD:
config wifi-iface

option device radio$devidx

option network lan

option mode ap

option ssid OpenWrt_$(cat /sys/class/ieee80211/${dev}/macaddress|awk -F “:” ‘{print $4″”$5″”$6 }’| tr a-z A-Z)option encryption none

option encryption none

option mode ap,配置模式为AP。例如WDS之类。
option ssid OpenWrt_$(cat /sys/class/ieee80211/${dev}/macaddress|awk -F “:” ‘{print $4″”$5″”$6 }’| tr a-z A-Z) 默认SSID为Openwrt_MAC后六位
option encryption none 是否开启加密,可以是psk、psk2、psk2-ccmp等
option network lan 位于哪个接口的管理之下,默认lan。一般无需修改

(3)-修改root密码

默认情况下root是没有密码的,需设定密码才能开启ssh。
修改shadow文件,位于package/base-files/files/etc
root:$1$wEehtjxj$YBu4quNfVUjzfv8p/PBo5.:0:0:99999:7:::

密码经过加密,将密码修改成admin。
(4)-修改路由连接数,优化网络参数

修改路由连接数,优化网络参数
连接数默认情况下是1.6万多吧。可以选择性修改。
修改sysctl.conf文件,位于package/base-files/files/etc/
net.netfilter.nf_conntrack_max=65535

65535自行替换。

(5)-默认中文,修改主机名,添加并修改默认主题,设定时区

默认中文,添加并默认主题
修改feeds/luci/libs/web/root/etc/config
option lang auto

改为

option lang zh_cn

并添加
config internal languages

option en ‘English’

option zh_cn ‘chinese’

添加主题
1.首先打开trunk/feeds/luci/themes这个目录,你会发现里面有很多主题(除了base为基础包外)每一个文件夹就
是一个主题
2.我们得修改makefile文件,使其制定编译的时候能找到openwrtcn这个主题
找到路径为trunk/feeds/luci/contrib/package/luci下面的makefile文件双击打开
搜索OpenWrt.org这样很快就定位到添加主题的地方了,在下面空白处增加一句
效果如下
$(eval $(call theme,base,Common base for all themes))

$(eval $(call theme,openwrt,OpenWrt.org ))

$(eval $(call theme,bootstrap,Bootstrap Theme))

$(eval $(call theme,openwrtcn,openwrtcn Theme (default),,,1))

$(eval $(call theme,freifunk-bno,Freifunk Berlin Nordost Theme,\

Stefan Pirwitz <stefan-at-freifunk-bno-dot-de>))

$(eval $(call theme,freifunk-generic,Freifunk Generic Theme,\

Manuel Munz <freifunk-at-somakoma-dot-de>))

保存退出即可。

修改默认主题
修改feeds/luci/libs/web/root/etc/config
option mediaurlbase /luci-static/openwrt.org

可根据需要将openwrt.org修改为Bootstap、openwrtcn、freifunk-bno、freifunk-generic

修改主机名,设定时区
修改package/base-files/files/etc/config/system
config system

option conloglevel 8

option cronloglevel 8

option hostname Openwrt

option timezone Asia/Shanghai

option timezone CST-8

config timeserver ntp

list server 0.openwrt.pool.ntp.org

list server 1.openwrt.pool.ntp.org

list server 2.openwrt.pool.ntp.org

list server 3.openwrt.pool.ntp.org

option enable_server 0

option hostname Openwrt 设定主机名

 

option timezone Asia/Shanghai 时区设置为亚洲/上海
option timezone CST-8 正8区
list server 就是ntp服务器了。

 

(6)-添加aria2,luci添加,web管理界面添加

aria2的源码来自于
http://sourceforge.net/projects/aria2/files/stable/
我们这里以aria2-1.17.1版本为例下载的源码格式为aria2-1.17.1.tar.bz2
aria2的依赖安装
很多人没安装这依赖编译时会报错的
sudo apt-get update

sudo apt-get install autoconf automake libcppunit-dev autopoint openssl libtool sphinx-common sphinxsearch libgcrypt11-dev libxml2-dev pkg-config

开始集成aria2c
首先把下载下来的aria2-1.17.1.tar.bz2放进openwrt源码根目录的dl目录
获取md5码
ctrl+alt+T弹出终端输入
md5sum /……/……/trunk/dl/aria2-1.17.1.tar.bz2 省略好代表openwrt的源码的路径补全,回车就能获取md5码,记住用用的

在/feeds/packages/net/aria2/路径下创建aria2c源码的makefile文件内容如下 (make文件及其他本文需要文件见文章最下方)

在feeds目录下面找到packages.index索引文件,添加aria2源码索引记录
双击打开packages.index,在任意位置添加如下代码
Source-Makefile: feeds/packages/net/aria2/Makefile

Package: aria2

Submenu: File Transfer

Version: 1.17.1-1

到这里aria2算是添加完了,用命令还可以使用,没luci界面是有点不方便,下面完美来添加luci-aria2
添加luci-aria2
文章末有我上传的luci-aria2的源码文件,下载下来后放到你的luci响应的目录,版本不宜样目录可能不宜样
trunk版本为例
把luci-aria2这个文件夹放进/trunk/feeds/luci/applications/这个目录里面
然后在trunk/feeds/目录下找到luci.index 这个索引文件,打开在任意位置添加如下代
Package: luci-app-aria2

Submenu: 3. Applications

Version: 0.11+svk-1

Depends: +libc +USE_EGLIBC:librt +USE_EGLIBC:libpthread +PACKAGE_luci-app-aria2:aria2

保存退出即可
到这里就集成完了
最后在终端执行
./scripts/feeds install -a

make menuconfig

make menuconfig
就可以在luci>3. Applications 找到luci-app-aria2了
(7)-添加fullflash分区,uboot、art分区可写

修改target/linux/ar71xx/files/drivers/mtd/tplinkpart.c
#define TPLINK_NUM_PARTS 5

改为
#define TPLINK_NUM_PARTS 6

(即在原有的数值上加1)
然后在文件中找到以下内容
parts[0].name = “u-boot”;

parts[0].offset = 0;

parts[0].size = offset;

parts[0].mask_flags = MTD_WRITEABLE;

parts[1].name = “kernel”;

parts[1].offset = offset;

parts[1].size = rootfs_offset – offset;

parts[2].name = “rootfs”;

parts[2].offset = rootfs_offset;

parts[2].size = art_offset – rootfs_offset;

parts[3].name = “art”;

parts[3].offset = art_offset;

parts[3].size = TPLINK_ART_LEN;

parts[3].mask_flags = MTD_WRITEABLE;

parts[4].name = “firmware”;

parts[4].offset = offset;

parts[4].size = art_offset – offset

在 parts[4].size = art_offset – offset 后面换一行,添加这段
parts[5].name = “fullflash”;

parts[5].offset = 0;

parts[5].size = master->size

uboot、art分区可写,目的是使用ttl刷新uboot、art
注释掉 parts[0].mask_flags = MTD_WRITEABLE;

(8)-顶部菜单添加按钮

比如在顶部菜单添加释放内存按钮

修改/modules/admin-full/luasrc/controller/admin/index.lua

+ entry({“admin”, “Free_Memory”}, call(“Free_Memory”), _(“Free Memory”), 81)

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