Linux Programming Environment Setup

1Linux Programming Environment Setup Outline  Introduce Linux  Install Linux on Vmware 在 Windows 下常用的 Software  Practice 2 INTRODUCE LINUX 3 History  Linus Torvalds make a Minix (Mini Unix) kernel  Just only 10000 row of C codes  Richard Stallman bring up GNU plan  Open source  Free  Unix-like  GNU/Linux  Linux  Kernel + many modules 4 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 5 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 6 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 7 Other  There’s nothing impossible on Linux, because Source code can change  Find Linux distribution or modules   Good Web Site  8 INSTALL LINUX ON VMWARE 9 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 10 Install Linux – Vmware 11 Install Linux – Virtual Host 12 13 Install Linux – Typical (Virtual Host) 14 Install Linux – Virtual Host 15 Install Linux – Virtual Host 16 Install Linux – Virtual Host 17 Install Linux – Virtual Host 18 Install Linux – Virtual Host 19 Install Linux – Virtual Host, Linux 20 Install Linux – image, download 21 Install Linux – Linux image 22 Install Linux – Linux Install Linux – image 23  Mainly, press the “Next” forever  We’ll point out options that need to setup below 24 25 Install Linux – 26 Install Linux – Install Linux – 27 Install Linux – 28 Install Linux –  只選擇以下套件  Development Tools  Editors 29 Install Linux – 30 Install Linux – image 31 Install Linux – 32 Install Linux – 33 34 Linux – network sshd 35 36 37 Windows Software – Linux 38 Pietty – Telnet  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  39 40 41 Winscp – ftp  Support  SFTP (SSH File Transfer Protocol)  SCP (Secure Copy Protocol)  FTP (File Transfer Protocol)  Good way to transmission data between Windows and Linux  42 43 44 LINUX COMMON COMMANDS 45 Linux Command Format  Command [–options] [param1] [param2]  Short option use “-”  Long option use “--”  Ex.  dmesg  gcc –v  gcc ––help  cp file1 file2 46 File management  ls  list  ls –al  chmod  change authority  -rw-r--r-- 1 root root 20 Sep 25 12:12 123.log 47 d : directory l : soft-link - : file c : char device b : block device owner group other r w x 222120 Ex. Chmod 755 file -rwxr-xr-x  rmdir  remove directory  mkdir  make directory  cp  copy  cp from to  mv  move or rename  Move from to  cd  change directory  cd  cd –  cd .. 48  find -name  find file  find –name  grep  find string  dmesg | grep CPU  cat  print to stdout  file  print file info.  touch  change file’s timestamp  make a file 49  rm  remove  rm –rf  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 50 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  netstat show the network status  netstat -l 51 System  reboot  shutdown –r  shutdown  shutdown -h now  ps  print process  ps aux  kill  terminate process  kill  killall 52  uname  show system info.  uname –r  uname –a  free  memory allocate state  sync  store memory buf. to disk 53 Vi Editor  vi filename 54 Visual Mode  yy  copy a row  p  paste a row  dd  delete a row 55 Insert Mode  Input what you want 56 Command Mode  :wq  save file and quit  :q!  un-save and quit  :100  jump to 100th row  /  find [key] in this file  press “n” to “Next” 57 Tips  Tab  Command complement  File complement  Up/Down  Record command  history  ` `  First to do  Ex. ifconfig `cat net.conf`  net.conf  eth0 x.x.x.x 58 PRACTICE 59 First program - Hello World ~!  touch test.c  新增一檔案  vi test.c  撰寫 code  gcc test.c –o test  編譯程式  gcc -o  ./test  執行程式 60 //test.c #include int main (int argc, char *argv[]) { printf("Hello world~!\n"); return 0; } Homework  實現該 Linux 程式設計環境, 並利用已有之 程式碼編譯和執行出一簡單範例  程式碼請至課程網站 download (helloworld_sock)  Report Format  作業描述  流程圖  執行結果  問題與討論  心得 61  Submission  以一個學號命名之壓縮檔(此報告)於期限內 E- Mail 寄至助教信箱和繳交紙本給助教  鄭玴吉 : ES711: g9517702@yuntech.edu.tw  林宜鋒 : ES711: g9517733@yuntech.edu.tw  Deadline  2008/03/19 晚上12點前  若有疑問可至ES711詢問助教 62
