平台：

Linux version 2.6.32-279.el6.x86_64

交叉编译器路径：/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-

开发板：FL2440

开发板运行内核：linux3.0

开发板文件系统：initramfs

easycwmp是基于cwmp协议开发出的CPE客户端，它的运行需要相应的库文件和脚本文件，只有把这些文件放在easycwmp能找到的位置，并且里面的内容符合我们自己的开发板，它才会运行的好。我用的是initramfs文件系统，initramfs运行在RAM，掉电后数据会丢失，所以把apps挂载到另一个分区，并把easycwmp放到apps里面，这样就不用每次重启都重新设置。

用mount命令可以查看分区挂载情况

/ >: mount
rootfs on / type rootfs (rw)
proc on /proc type proc (rw,relatime)
usbfs on /proc/bus/usb type usbfs (rw,relatime)
tmpfs on /dev type tmpfs (rw,relatime)
ramfs on /tmp type ramfs (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
ubi7:apps on /apps type ubifs (rw,sync,noatime)
/dev/mtdblock8 on /data type jffs2 (rw,sync,noatime)
/ >:

在PC上easycwmp用到的脚本都放在默认位置，在我的FL2440上要做一些更改，以适应我的文件系统（掉电丢失）

1.在apps下创建相关目录用以存放项目程序

/ >:mkdir -p /apps/easycwmp

2.因为我是在192.168.1.3的机器（以后简称.3服务器）上交叉编译easycwmp的，所以需要把.3服务器上的相关脚本通过tftp放到FL2440开发板上，把所有用到的脚本全部放到scripts目录里，各个脚本需要你自己从安装的位置拷贝过来

把它们全部打包放在/tftp目录下

3. 把库文件全部打包放到/tftp目录里面

4.把用到的uci,ubusd,jshn,easycwmpd放到/tftp目录里面

5.在FL2440上编写一个配置文件，用以把我们刚刚放到.3服务器上的库文件，脚本文件放到相应地方

/ >: vim conf.sh

#!/bin/bash
mkdir -p /apps/easycwmp/lib
mkdir -p /apps/easycwmp/bin
echo "----------------load libs-------------------------"
cd /apps/easycwmp/lib
tftp -gr cwmplib.tar.bz2 192.168.1.3
tar -xjf cwmplib.tar.bz2
chmod 777 *
ls

echo "----------------load scripts-----------------------"
cd /apps/easycwmp/scripts
tftp -gr cwmpscripts.tar.bz2 192.168.1.3
tar -xjf cwmpscripts.tar.bz2
chmod 777 *
ls

cd

mkdir -p /etc/easycwmp
mkdir -p /etc/config/
mkdir -p /lib/functions/

echo "----------------make link-----------------------"
ln -sf /apps/easycwmp/bin/easycwmpd /usr/sbin/easycwmpd
ln -sf /apps/easycwmp/scripts/easycwmp.sh /usr/sbin/easycwmp
ln -sf /apps/easycwmp/scripts/easycwmp /etc/config/easycwmp
ls -l /usr/sbin/easycwmpd
ls -l /usr/sbin/easycwmp
ls -l /etc/config/easycwmp

echo "----------------cp uci.sh to /lib/config/-----------------------"
mkdir -p /lib/config/
cp /apps/easycwmp/scripts/uci.sh /lib/config/uci.sh
ls /lib/config/uci.sh

echo "----------------load ubusd -----------------------"
cd /usr/sbin
tftp -gr ubusd 192.168.1.3
chmod 777 ubusd
ls /usr/sbin/ubusd

echo "-----------------load uci--------------------------"
cd /sbin
tftp -gr uci 192.168.1.3
chmod 777 uci
ls /sbin/uci

export UCI_CONFIG_DIR="/apps/easycwmp/scripts/"
export UBUS_SOCKET="/tmp/ubus.sock"

echo "---------------load jshn----------------------------"
cd /bin
tftp -gr jshn 192.168.1.3

echo "----------------get easycwmpd--------------------------"
cd /apps/easycwmp/bin
tftp -gr easycwmpd 192.168.1.3
chmod 777 easycwmpd
ls

echo "all done!"

6.执行该脚本

/ >:sh conf.sh

执行该脚本后lib下应该有的文件是

scripts下应该有

你还应该看到

需要说明的是：

a.我的文件系统是用busybox-1.20.0制作的，它的bash不支持easycwmp的相关语法，于是我重新交叉编译了bash

（也可以考虑升级busybox，busybox下载地址http://www.busybox.net/downloads/）

bash下载地址http://ftp.gnu.org/gnu/bash/，我下载的是bash-4.3,

创建build.sh

vim build.sh

#!/bin/bash
PRJ_PATH=`pwd`
#CROSS=/opt/buildroot-2011.11/arm920t/usr/bin/arm-linux-
CROSS=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-

export CC=${CROSS}gcc
export CPP=${CROSS}cpp
export AS=${CROSS}as
export LD=${CROSS}ld
export AR=${CROSS}ar
export RANLIB=${CROSS}ranlib
export STRIP=${CROSS}strip
exprot bash_cv_getenv_redef=no

make distclean

./configure --host=arm-linux --prefix=${PRJ_PATH}/../install \
--enable-static-link --without-bash-malloc

${CROSS}strip bash
make

make install

执行sh build.sh

把bash放到/tftp

b.busybox-1.20.0也不支持easycwmp里的getopt命令，于是交叉编译getopt，getopt是内嵌在util-linux-ng里的，交叉编译util-linux-ng里面会生成getopt

util-linux-ng下载网址ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/

我下载的是util-linux-ng-2.16.tar.gz

创建build.sh

[weishusheng@localhost util-linux-ng-2.16]$ vim build.sh
#!/bin/bash
PRJ_PATH=`pwd`
#CROSS=/opt/buildroot-2011.11/arm920t/usr/bin/arm-linux-
CROSS=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-
make distclean

export CC=${CROSS}gcc
export CPP=${CROSS}cpp
export AS=${CROSS}as
export LD=${CROSS}ld
export AR=${CROSS}ar
export RANLIB=${CROSS}ranlib
export STRIP=${CROSS}strip

./configure --host=arm-linux --without-ncurses --prefix=/home/weishusheng/myfl2440/cwmp/fl-easy
cwmp/install
make && make install

执行sh build.sh

把getopt放到/tftp目录下

[weishusheng@localhost util-linux-ng-2.16]$ cp /home/weishusheng/myfl2440/cwmp/fl-easycwmp/install/bin/getopt /tftp

c.在FL2440板子上没有curl,需要交叉编译curl

下载地址http://curl.haxx.se/download.html

我下的是curl-7.41.0版本

创建build.sh

[weishusheng@localhost curl-7.41.0]$ vim build.sh
#!/bin/bash
PRJ_PATH=`pwd`
#CROSS=/opt/buildroot-2011.11/arm920t/usr/bin/arm-linux-
CROSS=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-
make distclean
autoreconf -i
export CC=${CROSS}gcc
export CPP=${CROSS}cpp
export AS=${CROSS}as
export LD=${CROSS}ld
export AR=${CROSS}ar
export RANLIB=${CROSS}ranlib
export STRIP=${CROSS}strip
./configure --host=arm-linux --prefix=${PRJ_PATH}/../install --without-ssl
make && make install

执行sh build.sh ,并把curl及libcurl.so ，libcurl.so.4，libcurl.so.4.3.0放到/tftp 目录下

d.shflags.sh也需要放到板子上，我用的shflags-1.0.3/src下的shflags，它是个脚本，不用交叉编译，将shflags重命名为shflags.sh就好

下载地址：http://www.filewatcher.com/m/shflags-1.0.3.tgz.43549-0.html

它里面的内容：

7.FL2440上修改/apps/easycwmp/scripts/easycwmp.sh

/apps/easycwmp/scripts >: vim easycwmp.sh
#!/bin/sh
# Copyright (C) 2012-2014 PIVA Software <www.pivasoftware.com>
# Author: MOHAMED Kallel <mohamed.kallel@pivasoftware.com>
# Author: AHMED Zribi <ahmed.zribi@pivasoftware.com>

# Copyright (C) 2011-2012 Luka Perkov <freecwmp@lukaperkov.net>

. /apps/easycwmp/scripts/functions.sh
. /apps/easycwmp/scripts/jshn.sh
. /apps/easycwmp/scripts/shflags.sh
. /apps/easycwmp/scripts/defaults

UCI_GET="/sbin/uci -q ${UCI_CONFIG_DIR:+-c $UCI_CONFIG_DIR} get"
UCI_SET="/sbin/uci -q ${UCI_CONFIG_DIR:+-c $UCI_CONFIG_DIR} set"
UCI_SHOW="/sbin/uci -q ${UCI_CONFIG_DIR:+-c $UCI_CONFIG_DIR} show"
UCI_COMMIT="/sbin/uci -q ${UCI_CONFIG_DIR:+-c $UCI_CONFIG_DIR} commit"

......

主要修改functions.sh，jshn.sh,shflags.sh,defaults的加载路径，再把最后一行的

#handle_action 2>/dev/null

改为

handle_action

这样才能看到出错信息，不然要是脚本执行出现什么问题都看不到打印信息

8.FL2440上修改network.sh

/apps/easycwmp/scripts >: vim network.sh

把第一行改为，（即jshn.sh的真实加载路径）
. /apps/easycwmp/scripts/jshn.sh

9.FL2440上修改easycwmp（黑色字体标注的是命令和更改的地方）

/apps/easycwmp/scripts >: vim easycwmp
# easycwmp uci configuration

config local
option interface eth0
option port 7547
option ubus_socket /var/run/ubus.sock
option date_format %FT%T%z
option username easycwmp
option password easycwmp

config acs
option scheme http
option username openacs
option password openacs
option hostname 192.168.1.21
option port 8080
option path /openacs/acs
option parameter_key '1'
option periodic_enable 'true'
option periodic_interval '180'
option periodic_time '1'

config device
option manufacturer easycwmp
option oui FFFFFF
option product_class mycwmp
option serial_number FFFFFF123456
option hardware_version example_hw_version
option software_version example_sw_version

config scripts
# load OpenWrt generic network functions
list location /apps/easycwmp/scripts/network.sh
# load easycwmp common functions
list location /apps/easycwmp/scripts/common
# easycwmp specific functions
list location /apps/easycwmp/scripts/device_info
list function device_info
list location /apps/easycwmp/scripts/lan_device
list function lan_device
list location /apps/easycwmp/scripts/management_server
list function management_server
list location /apps/easycwmp/scripts/wan_device
list function wan_device

10.FL2440上修改defaults

/apps/easycwmp/scripts >: vim defaults
#!/bin/sh
# Copyright (C) 2011-2012 Luka Perkov <freecwmp@lukaperkov.net>

# set these to appropriate values and remove comment if you want to use them

#default_management_server_acs_hostname=""
default_management_server_connection_request_url="http://192.168.1.21:8080/openacs/acs"
#default_wan_device_mng_interface_ip=""
#default_wan_device_mng_interface_mac=""
#default_device_hosts_dnsmasq_leases_file=""
~

11.我在做文件系统时自动设置系统在启动时去/apps/etc/init.d/里面去执行以S打头的文件，所以我在/apps/etc/init.d/里写了个easycwmp的配置脚本，使得不用每次都手动把库文件、exe文件都拷贝到相应目录下

首先需要将用到的.3服务器上的bash,getopt,jshn,curl,uci,ubusd放到开发板/apps/easycwmp/bin/里面，在编写脚本S23_cwmp

/apps/etc/init.d >: pwd
/apps/etc/init.d
/apps/etc/init.d >: vim S23_cwmp

#!/bin/sh

ifconfig eth0 192.168.1.23
route add default gw 192.168.1.1

mkdir -p /etc/easycwmp
mkdir -p /etc/config/
mkdir -p /lib/functions/

echo "----------------make link-----------------------"
ln -sf /apps/easycwmp/bin/easycwmpd /usr/sbin/easycwmpd
ln -sf /apps/easycwmp/scripts/easycwmp.sh /usr/sbin/easycwmp
ln -sf /apps/easycwmp/scripts/easycwmp /etc/config/easycwmp
ls -l /usr/sbin/easycwmpd
ls -l /usr/sbin/easycwmp
ls -l /etc/config/easycwmp

echo "----------------cp uci.sh to /lib/config/-----------------------"
mkdir -p /lib/config/
cp /apps/easycwmp/scripts/uci.sh /lib/config/uci.sh
ls /lib/config/uci.sh

echo "----------------cp ubusd to /usr/sbin-----------------------"

cp /apps/easycwmp/bin/ubusd /usr/sbin
ls /usr/sbin

echo "-----------------cp uci to /sbin--------------------------"
cd /sbin
cp /apps/easycwmp/bin/uci /sbin

ls /sbin/uci

cp /apps/easycwmp/bin/curl /usr/bin

cp /apps/easycwmp/bin/jshn /bin/

export UCI_CONFIG_DIR="/apps/easycwmp/scripts/"
export UBUS_SOCKET="/tmp/ubus.sock"

rm /bin/getopt
cp /apps/easycwmp/bin/getopt /bin/

rm /bin/sh
cp /apps/easycwmp/bin/bash /bin

ln -sf /bin/bash /bin/sh

写完这个脚本以后，

以上工作都做好后就可以启动服务器，我们可以执行easycwmp --json get name "" 0 来测试cpe支持的数据模型

你将看到

{ "parameter": "InternetGatewayDevice.", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.Manufacturer", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.ManufacturerOUI", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.ProductClass", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.SerialNumber", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.HardwareVersion", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.SoftwareVersion", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.UpTime", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.DeviceLog", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.SpecVersion", "fault_code": "", "writable": "0" }

{ "parameter": "InternetGatewayDevice.DeviceInfo.ProvisioningCode", "fault_code": "", "writable": "1" }

......

最后启动easycwmpd链接我们的openacs
