OBEE's DIY: Cubox for CAS #6 : 安裝 Cubox 的 Linux (下)

之前做好了 Yo 的 Linux image, 開了 Cubox, 找到了 Cubox 的 IP 并可透過 SSH 看到登入畫面, 以下會做一些客化, 包括:
1. 刪去日文的設定
2. 設定 mpd 的 configure 檔
3. 設定 NAS 的 file sharing mapping (在 rc.local 內)
4. 把系統會寫的file 移至 RAM drive 上 (廷長 micro SD 的壽命)

1. 刪去日文的設定
開了機, SSH 入去後 (username = root, password = cubox), 執行:

apt-get update && apt-get -y upgrade; apt-get -y remove --purge language-pack-*; apt-get -y install lighttpd language-pack-en-base;

再執行:

dpkg-reconfigure locales; export LANG=en_HK.UTF-8; dpkg-reconfigure tzdata; apt-get update && apt-get -y upgrade; echo "export LANG=en_HK.UTF-8;" >> /root/.profile; apt-get -y autoremove; reboot

它會問你當前的 Locale, 只要選 "Asia", "Hong Kong" 便可.

到了最後它會自己 reboot. Reboot 後又 SSH 登入. 再執行:

echo "alias ls='ls -la --color=auto'" >> /root/.profile;
cd /var; mv /var/log /run
ln -s ../run/log log
cd /var/lib; mv /var/lib/urandom /run
ln -s /run/urandom /var/lib/urandom
mv /var/lib/dhcp /run
ln -s /run/dhcp /var/lib/dhcp
mv /root/.bash_history /run
ln -s /run/.bash_history /root/.bash_history
mkdir -p /run/music
ln -s /run/music /music
ln -s /music /var/www/music

2. 設定 mpd 的 configure 檔
執行:

mv /etc/mpd.conf /etc/mpd.conf.org
nano /etc/mpd.conf

(nano 的簡單教學: [轉] 基本 Nano 指南)

Copy & Paste 以下內容　(可用 mouse highlight 下面藍色的字，再按 ctrl-C，　然後把滑老放標放在 putty 的 nano 內按 right click)

music_directory         "/music"
playlist_directory      "/music/.mpdConf/playlists"
db_file                 "/music/.mpdConf/cubox/db"
log_file                "/run/mpd/log"

# An example of an ALSA output:

        device          "hw:0,0"        # optional
        priority        "FIFO:52"
        dsd_usb         "yes"
}

請自行修改粉紅色的內容, 其中,

"My ALSA Device" 是你的DAC在MPaD上顯示的名稱

按下 Ctrl+O。再按下 Ctrl+X 離開 nano

離開 nano 之後執行:

chown mpd:audio /etc/mpd.conf

3. 設定 NAS 的 file sharing mapping

nano -w /etc/rc.local

(nano 的簡單教學: [轉] 基本 Nano 指南)

清除原來的內容, 然後　Copy & Paste 以下內容　(可用 mouse highlight 下面藍色的字，再按 ctrl-C，　然後把滑老放標放在 putty 的 nano 內按 right click)

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
chrt -f -p 53 `pgrep -n cifsd`
chrt -f -p 53 `pgrep -o cifsd`

mount -t cifs -o uid=mpd,file_mode=0666,dir_mode=0766,iocharset=utf8,\
rsize=130048,wsize=4096,\
username=mpduser,password=mpd1234 192.168.0.101:/Music /run/music
service mpd restart
mpc update
find /run/music/USB -type d -empty -delete

exit 0

請自行修改粉紅色的內容, 其中,

mpduser 是你打 NAS 上的 music folder 分享的用戶名稱,
mpd1234 是你打 NAS 上的 music folder 分享的用戶密碼,
192.168.0.101:/Music 是你打 NAS 上的 music folder 分享的link,

按下 Ctrl+O。再按下 Ctrl+X 離開 nano

4. 把系統會寫的file 移至 RAM drive 上

執行:

nano /etc/init.d/readonlySetup

(nano 的簡單教學: [轉] 基本 Nano 指南)

貼上以下

#!/bin/sh

### BEGIN INIT INFO
# Provides:          read-only file-system preparation
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: prepare for read-only root FS
# Description:       prepare for read-only root FS
### END INIT INFO

prep_start () {
        echo "Prep for read-only FS"
        echo heartbeat > /sys/class/leds/cubox:red:health/trigger
   /bin/mkdir -p /run/log/lighttpd /run/tmp /run/urandom /run/dhcp /run/music/.mpdConf/cubox /run/music/.mpdConf/playlists
        /bin/touch /run/.bash_history /run/music/.mpdConf/cubox/db /run/music/.mpdConf/cubox/state /run/music/.mpdConf/cubox/sticker.sql
        /bin/chmod -R 777 /run/log /run/tmp /run/urandom /run/dhcp /run/music
   #/bin/mount -o remount,ro /
}

prep_stop () {
        echo "Prep for read-only FS (stop)"
   /bin/mount -o remount,rw /
}

case "$1" in
    start)
        prep_start
        ;;
    stop)
        prep_stop
        ;;
    *)
        echo "Usage: $0 {start|stop}"
        exit 2
        ;;
esac

按下 Ctrl+O。再按下 Ctrl+X 離開 nano

離開 nano 之後執行:

chmod 777 /etc/init.d/readonlySetup
cd /etc/rc2.d
ln -s ../init.d/readonlySetup S10readonlySetup
cd ..
cd /etc/rc3.d
ln -s ../init.d/readonlySetup S10readonlySetup
cd ..
cd /etc/rc4.d
ln -s ../init.d/readonlySetup S10readonlySetup
cd ..
cd /etc/rc5.d
ln -s ../init.d/readonlySetup S10readonlySetup
reboot
