DDWRT打造全能服务器(DDWRT安装SVN Server)

下文所用路由器型号为:WNDR3700V4

参考链接：http://dd-wrt.ca/phpBB2/viewtopic.php?t=86912&highlight=optware

由于WNDR3700V4的芯片是Atheros，Atheros并不支持optware，下面我们来用openwrt的opkg玩转全能服务器。

1，安装opkg到U盘

启动USB支持

Under Services->USB:
* Enable Core USB Support
* Disable USB Printer Support (enable it if you need printing support)
* Enable USB Storage Support
* Enable Automatic Drive Mount 
* Click Apply Settings 

在U盘创建相关目录结构，U盘默认mount到了/mnt/sda1

 cd /mnt/sda1
 mkdir /sda_part1 
 cd /mnt/sda1/sda_part1 
 mkdir etc opt root 
 touch optware.enable 
 chmod 755 etc opt root 
 mkdir opt/lib 
 chmod 755 opt/lib 
 cp -a /etc/* /mnt/sda1/sda_part1/etc/ 
 mount -o bind /mnt/sda1/sda_part1/etc /etc 
 mount -o bind /mnt/sda1/sda_part1/opt /jffs 

安装libc和opkg包

wget http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/packages/libc_0.9.33.2-1_ar71xx.ipk
ipkg install libc_0.9.33.2-1_ar71xx.ipk
wget http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/packages/opkg_618-3_ar71xx.ipk
ipkg install opkg_618-3_ar71xx.ipk

为opkg创建配置文件

cat > /etc/opkg.conf << EOF 
src/gz snapshots http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages 
dest root /opt 
dest ram /opt/tmp 
lists_dir ext /opt/tmp/var/opkg-lists 
EOF 

mount到相关目录

umount /jffs 
mount -o bind /mnt/sda1/sda_part1/root /tmp/root 
mount -o bind /mnt/sda1/sda_part1/opt /opt 
export LD_LIBRARY_PATH='/opt/lib:/opt/usr/lib:/lib:/usr/lib' 
opkg update 

执行此操作，你能够看到

Downloading http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/Packages.gz.  
Updated list of available packages in /opt/tmp/var/opkg-lists/snapshots.

6. Set the startup script to make the changes take effect each time upon reboot

Under DD-WRT’s web interface, Administration->Commands, input the following commands in the window then click "Save Startup":

#!/bin/sh 

sleep 5 
if [ -f /mnt/sda1/sda_part1/optware.enable ]; then 
mount -o bind /mnt/sda1/sda_part1/etc /etc 
mount -o bind /mnt/sda1/sda_part1/root /tmp/root 
mount -o bind /mnt/sda1/sda_part1/opt /opt 
else 
exit 
fi 

if [ -d /opt/usr ]; then 
export LD_LIBRARY_PATH='/opt/lib:/opt/usr/lib:/lib:/usr/lib' 
export PATH='/opt/bin:/opt/usr/bin:/opt/sbin:/opt/usr/sbin:/bin:/sbin:/usr/sbin:/usr/bin' 
else 
exit 
fi 

7. Modification of the profile file

SSH into your box then copy/paste the commands below to PuTTY window to create a script running each time when user root logins:

cat > /mnt/sda1/sda_part1/root/.profile << EOF 
export LD_LIBRARY_PATH='/opt/lib:/opt/usr/lib:/lib:/usr/lib:/opt/usr/local/lib' 
export PATH='/sbin:/opt/bin:/opt/usr/bin:/opt/sbin:/opt/usr/sbin:/bin:/usr/bin:/usr/sbin:/opt/usr/local/bin' 
export PS1='\[\033[01;31m\]\u@\h \[\033[01;34m\]\W \$ \[\033[00m\]' 
export TERMINFO='/opt/usr/share/terminfo' 
EOF
