  1. Introduce Linux Speaker: Yi-Ji Jheng Date: 2007.09.26

  2. Outline • Introduce Linux • Install Linux on Vmware • Common software • Linux commands and Practice

  3. INTRODUCE LINUX

  4. History • Linus Torvalds make a Minix (Mini Unix) kernel • Just only 10000 row of codes for C • Richard Stallman bring up GNU plan • Open source • Free • Unix-like • GNU/Linux  Linux • Kernel + many modules

  5. Use • Server • MySql + PHP + Apache • Embedded system • STB (Set Top Box) • Super Computer • 75% (Top 500 on the world) • Game • Sony PlayStation 3 • Microsoft XBOX

  6. Linux Kernel • Linux Kernel version format • Linux-a.b.c • a  kernel version • b  odd : test  even : stable • c  number of bug fix • Common, Linux-2.4.x and Linux-2.6.x

  7. Linux distribution • Redhat 9  Linux-2.4.x • Fedora 1  Linux-2.4.x • Fedora 2~  Linux-2.6.x • Debian  more app. (15940) • Trustix  more safe and stable • Knoppix  LiveCD

  8. Other • It’s not must on Linux, because Source code can change • Find Linux distribution or modules • 義守大學檔案伺服器http://ftp.isu.edu.tw/ • Good Web Site • 鳥哥的 Linux 私房菜 http://linux.vbird.org/

  9. INSTALL LINUX ON VMWARE

  10. Vmware • Use software (VMware ESX Server) to“virtualize”the hardware resources • Including the CPU, RAM, hard disk and network controller • To create a virtual machine that can run its own operating system and applications just like a “real” computer

  11. Install Linux

  12. Mainly, press the “Next” forever • We’ll point out options that need to setup below

  13. Because it’ll be “Host Linux”, we only select below • DevelopmentTools • Editors

  14. setup • all sevice close, only network and sshd

  15. COMMON SOFTWARE

  16. Pietty • Use SSH ( Secure Shell ) protocol • Allows data to be exchanged over a secure channel between two computers • Why use it? • Convenient for In/Out Vmware console • Good copy way • http://ntu.csie.org/~piaip/pietty/

  17. Winscp • Support • SFTP (SSH File Transfer Protocol) • SCP (Secure Copy Protocol) • FTP (File Transfer Protocol) • Good way to transmission data between Windows and Linux • http://winscp.net/eng/docs/lang:cht

  18. LINUX COMMANDS AND PRACTICE

  19. Linux Command Format • Command [–options] [param1] [param2] … • Short option use “-” • Long option use “--” • Ex. • dmesg • gcc –v • gcc ––help • cp file1 file2

  20. File management • ls  list • ls –al • chmod  change authority • -rw-r--r-- 1 root root 20 Sep 25 12:12 123.log other group r w x 222120 Ex. Chmod 755 file d : directory l : soft-link - : file c : char device b : block device owner -rwxr-xr-x

  21. rmdir  remove directory • mkdir  make directory • cp  copy • cp from to • mv  move or rename • Move from to • cd  change directory • cd <absoluteor relative path> • cd – • cd ..

  22. find -name  find file • find <where> –name <filename> • grep  find string • dmesg | grep CPU • cat  print to stdout • file  print file info. • touch  change file’s timestamp  make a file

  23. rm  remove • rm –rf <file or directory> • man  command manual • tar  uncompress or compress • tar zxvf file.tar.gz • tar zcvf backup.tar.gz /root • tar jxvf file.tar.bz2 • ln  soft-link • ln –s <file> <link_name>

  24. Network • route  setup or print route rule • ping • ping -c 4 www.google.com.tw • ifconfig  setup or print network • Ifconfig eth0 xxx.xxx.xxx.xxx

  25. System • reboot • shutdown –r • shutdown • shutdown -h now • ps  print process • ps aux • kill  terminate process • kill <PID> • killall <service_name>

  26. uname  show system info. • uname –r • uname –a • Free  memory allocate state • sync  store memory buf. to disk
