树莓派3安装openwrt

1.在编译openwrt之前,需要先安装依赖包,命令如下:

sudo apt-get install autoconf binutils bison bzip2 flex gawk gettext make libncurses5-dev patch unzip wget zlib1g curl libcurl3 openssl libssl-dev perl libperl-dev cpio libexpat1 gettext openssh-client subversion cmake libtool

2.然后新建用户

#adduser openwrt

3.再开始编译openwrt源码生成镜像文件

3.1.首先下载openwrt源码,
下载地址:https://github.com/openwrt/openwrt/tree/chaos_calmer
或者使用git工具(要先装git工具),输入下列命令:

git clone git://git.openwrt.org/openwrt.git

参考:https://dev.openwrt.org/wiki/GetSource

3.2.然后解压下载的文件

解压zip格式的压缩文件的话使用:

unzip openwrt***.zip

如果使用git联网下载就不需要解压。
3.3.然后进入openwrt文件夹

#cd openwrt

3.4.添加软件扩展包

./script/feeds update -a #更新所有附加的包(如:luci 等等)
./script/feeds install -a #安装所有更新的包

3.5.接着,测试编译环境

#make defconfig

3.6.进入定制界面,配置编译选项

make menuconfig #设置编译配置

选项配置参考:blog.csdn.net/xingyuzhe/article/details/48976501(其中有的选项位置和图片不一样,应该是版本不同,耐心找找就能找到位置,主要在"base system" "kernel modules" "luci" "network" "utilities")

上面的参考是树莓派的配置且用来制作无线路由的,自己的需要根据自身需要选择。

这里需要注意
1."target system"要根据自己板子的实际来选择,否则编译出来的系统放到开发板上也是跑不起来的,如果"target system"中没有完全匹配的可以,在"subtarget"中选择,然后在"target profile"中选择开发板名称
例如,我的是树莓派3,就应该在"target system"选择"Broadcom BCM2708",在"subtarget"中选择"Broadcom BCM2710",在"target profile"中选择"raspberrypi3 B"
2.其他配置中,下面列出部分自己找到的说明:

network中wpa-supplicant和wpa-psk的区别
WPA-PSK是指Pre-Shared Key,就是用户已经有了一个Key,通过这个Key来进行WPA认证,不需要认证服务器。如果不是PSK的话,需要认证服务器来产生Key。
WPA和WPA-PSK采用了相同的加密机制,其区别仅在于WPA-PSK的认证机制只有简单的一般密码,而非针对用户特定的身份认证。虽然这种一般密码式的方法存在被暴力破解的可能性,但是,与WEP相比,无线网络的安全性仍然大大强化。
从技术角度看,WPA主要解决了WEP在共享密钥上的漏洞,添加了用户级的认证措施。Wi-Fi联盟给出的WPA定义即为:
  WPA = 802.1X + EAP + TKIP + MIC
WPA只是在802.11i正式推出之前的Wi-Fi企业联盟的安全标准,802.11i,该标准通过使用CCM (Counter-Mode/CBC-MAC)认证方式和AES(Advanced Encryption Standard)加密算法,更进一步加强了无线局域网的安全和对用户信息的保护。

以上是配置中的选项的部分解释,备注一下。

3.7.最后是编译的过程,如下:

注意:编译的时候尽量使用root用户,否则,可能出现没有创建某个文件的权限,没有删除某个文件的权限等问题,此时,即便使用chmod改变所有文件的权限也行不通,因为,里面部分文件是临时创建的,创建出来的文件可能会没有权限。

make download #提前下载需要编译软件的源代码(可以跳过)
make V=99 #V=99表示显示编译详情(便于调试编译错误)
#等待编译完成,编译完成后所有的输出镜像和ipk包会在openwrt/bin目录下。
注意:部分安装包可能会很难下载,可以FQ下载下来,然后放到openwrt/dl目录下边。

下面给出地址,里面有我安装时需要的安装包:

下面是我编译出来的镜像(我的是树莓派3):

编译过程有几个问题需要注意
1.you should not run configure as root (set FORCE_UNSAFE_CONFIGURE=1 in environment to bypass this check)
解决方法
输入命令:export FORCE_UNSAFE_CONFIGURE=1
2.编译的时候尽量使用root用户,否则,可能出现没有创建某个文件的权限,没有删除某个文件的权限等问题,此时,即便使用chmod改变所有文件的权限也行不通,因为,里面部分文件是临时创建的,创建出来的文件可能会没有权限。
3.编译到后面,会有一个选择是否安装Broadcom BCM2835 camera interface driver的选项,此时要选N,如果选择Y,就会遇到
config.status: error: cannot find input file: `po/Makefile.in.in‘
Makefile:198: recipe for target ‘/home/openwrt/openwrt/build_dir/target-arm_arm1176jzf-s+vfp_musl-1.1.16_eabi/transmission-mbedtls/transmission-2.92+git/.configured_yyyyyyyy‘ failed
make[3]: *** [/home/openwrt/openwrt/build_dir/target-arm_arm1176jzf-s+vfp_musl-1.1.16_eabi/transmission-mbedtls/transmission-2.92+git/.configured_yyyyyyyy] Error 1
make[3]: Leaving directory ‘/home/openwrt/openwrt/feeds/packages/net/transmission‘
package/Makefile:196: recipe for target ‘package/feeds/packages/transmission/compile‘ failed
make[2]: *** [package/feeds/packages/transmission/compile] Error 2
make[2]: Leaving directory ‘/home/openwrt/openwrt‘
package/Makefile:193: recipe for target ‘/home/openwrt/openwrt/staging_dir/target-arm_arm1176jzf-s+vfp_musl-1.1.16_eabi/stamp/.package_compile‘ failed
make[1]: *** [/home/openwrt/openwrt/staging_dir/target-arm_arm1176jzf-s+vfp_musl-1.1.16_eabi/stamp/.package_compile] Error 2
make[1]: Leaving directory ‘/home/openwrt/openwrt‘
/home/openwrt/openwrt/include/toplevel.mk:192: recipe for target ‘world‘ failed
make: *** [world] Error 2
等问题,配置失败导致缺乏文件。
4.如果编译成功,也生成了镜像,但是写到板子上却无法启动,就要检查前面选择树莓派时的配置("target system")是否正确。
5.如果烧写到树莓派启动发现系统是read-only filesystem时,就要检查启动时,文件系统有没有问题,可能是镜像损坏了,重新写一个系统就能解决。

启动openwrt

整个编译过程结束后,可以在bin/brcm2708的目录下找到编译成功的镜像,使用工具烧写到SD卡上,然后插入到树莓派上通电就可以启动了。
