• 14:00~15:00 雲端技術展示 - 抓抓龍(Crawlzilla)簡報、展示
• 15:00~17:00 Crawlzilla 後續發展方向討論 - ​開 issue

• [備忘] ​Linux 遇到 kernel panic 後可自動重新開機(Auto Reboot)

  $ sudo sysctl -w kernel.panic = 20
  

  或者編輯 /etc/sysctl.conf 加入

  kernel.panic = 20
  

Storage Virtualization

Debian

• [緣起] 想要用 USB 拇指碟來安裝 Debian 5.0 (lenny)
• [參考] Debian GNU/Linux 安裝手冊 - ​4.4. 準備從 USB 隨身碟開機的檔案

  ~$ sudo su -
  ~# wget http://free.nchc.org.tw/debian/dists/Debian5.0.5/main/installer-amd64/current/images/hd-media/boot.img.gz
  ~# zcat boot.img.gz > /dev/sdb
  ~# mount /dev/sdb /mnt
  ~# cd /mnt
  /mnt# wget http://free.nchc.org.tw/debian-cd/current/amd64/iso-cd/debian-505-amd64-businesscard.iso
  ~# cd
  ~# umount /mnt
  

• [狀況] 找不到網路卡驅動程式 :(

Netboot.me

• [緣起] 想要用 USB 拇指碟來安裝 Debian 5.0 (lenny)
• [作法] 環保一點，所以下載 netboot.me USB Image

  $ wget http://static.netboot.me/gpxe/netbootme.usb
  

• 接上 USB 拇指碟，透過 /proc/partitions 確認磁碟位置

  $ cat /proc/partitions
  major minor  #blocks  name
  
     8        0  488386584 sda
     8        1  486327296 sda1
     8        2    2057216 sda2
     8       16    1957888 sdb
  

• 確認在 /dev/sdb 之後就使用 dd 把 USB Image 寫入拇指碟

  $ sudo dd if=netbootme.usb of=/dev/sdb
  

• [狀況] 找不到網路卡驅動程式 :(

• 安裝 Ubuntu 10.04 LTS 可以正常驅動
