00:00:00,000 --> 00:00:00,160

2
00:00:00,160 --> 00:00:02,660
>> SPEAKER 1: Id-dritt, ejja tagħti
tħares lejn kif is-soluzzjoni tal-persunal fil-fatt

3
00:00:02,660 --> 00:00:04,760
topera, sabiex inti
jiksbu sens, l-ewwel darba

4
00:00:04,760 --> 00:00:06,930
kif suppost il-web server
jiddekorri, u kif inti tista 'attwalment

5
00:00:06,930 --> 00:00:08,480
ġġibu running fuq il-kompjuter tiegħek.

6
00:00:08,480 --> 00:00:09,350
Allura stampa hawn.

7
00:00:09,350 --> 00:00:13,640
Stajt diġà installat fil CS50 ID
pset6 dot zip, kull l-ispeċifikazzjoni.

8
00:00:13,640 --> 00:00:16,197
Stajt unzipped, u stajt
CDed fis-direttorju pset6 tiegħi.

9
00:00:16,197 --> 00:00:18,780
Waħda mill-ewwel affarijiet int
tmur jridu jagħmlu, speċjalment

10
00:00:18,780 --> 00:00:22,010
jekk inti kont qed tuża IDE CS50 jilagħbu
flimkien ma 'lectures riċenti, fejn

11
00:00:22,010 --> 00:00:25,640
aħna kont qed tuża PHP fil
CS50 IDE, speċifikament,

12
00:00:25,640 --> 00:00:29,050
użu li web server Apache imsejħa,
fejn inti tista 'tibda u tieqaf

13
00:00:29,050 --> 00:00:30,910
ma dak il-kmand, Apache 50.

14
00:00:30,910 --> 00:00:34,160
L-ewwel, imorru quddiem u
tip "stop Apache 50"

15
00:00:34,160 --> 00:00:37,370
biss biex tiżgura li jekk inti kienu
wara flimkien fl-aħħar jiem,

16
00:00:37,370 --> 00:00:40,090
u inti mixgħula Apache, int
ddawwar it off b'dan il-mod

17
00:00:40,090 --> 00:00:41,360
billi jwaqqfu l-server.

18
00:00:41,360 --> 00:00:44,110
Issa, dak li jien ser tagħmel hu eżattament
dak l-spec jgħidlekx me li jagħmlu.

19
00:00:44,110 --> 00:00:49,770
Jien se jmorru biex Tilda mmejla CS50
server mmejla pset6, u biss hit Ikteb.

20
00:00:49,770 --> 00:00:52,840
Int ser ikollok avviż li jien għajjat ​​fil
ma 'xi Informazzjoni dwar lużu, fejn

21
00:00:52,840 --> 00:00:54,960
Inkun qed taħdem
il-programm kif server

22
00:00:54,960 --> 00:00:58,230
ma 'p sing fakultattiv u mbagħad
numru tal-port, li inti tista 'attwalment

23
00:00:58,230 --> 00:01:00,720
ħalli vojt għaliex mill
Konvenzjonalment, kull l-spec,

24
00:01:00,720 --> 00:01:04,010
l-web server se
jassumi li inti tixtieq port 8080.

25
00:01:04,010 --> 00:01:07,560
Sadanittant, inti tista 'recall li
port 8080 mhuwiex verament standard,

26
00:01:07,560 --> 00:01:09,380
pjuttost port 80 huwa l-
Numru konna tkellimna

27
00:01:09,380 --> 00:01:11,440
dwar jiġu l-default għall HTTP.

28
00:01:11,440 --> 00:01:14,870
Ukoll, jirriżulta li CS50 IDE
hija sempliċement konfigurati b'mod,

29
00:01:14,870 --> 00:01:18,730
tali li meta inti bi browser jippruvaw
biex iżuru port 80 mid-dinja ta 'barra,

30
00:01:18,730 --> 00:01:22,210
li għaddej biex issolvi tal magically
port quddiem, jew idawwru innifsu,

31
00:01:22,210 --> 00:01:25,200
port 8080 ġewwa
ta 'server tiegħek stess.

32
00:01:25,200 --> 00:01:29,330
>> Allura l-aħħar ħaġa hawnhekk huwa l-kmand
argument linja, il-passaġġ għall rotta.

33
00:01:29,330 --> 00:01:31,590
U minn dak I biss
mean, dak folder do I

34
00:01:31,590 --> 00:01:34,820
tixtieq li tgħid il-server
għall-użu biex iservu up fajls?

35
00:01:34,820 --> 00:01:39,030
Fi kliem ieħor, jekk iż-żjarat utent
mmejla, liema jekk hu jew hi tara?

36
00:01:39,030 --> 00:01:41,030
Well, ejja imorru quddiem u
run eżattament dan mill-ġdid,

37
00:01:41,030 --> 00:01:43,940
din id-darba tispeċifika li I
jridu li l-għerq tal-web server tiegħi

38
00:01:43,940 --> 00:01:48,210
li jkun il-f'direttorju pubbliku, li jiġi
bil-problema stabbiliti sitt kodiċi ta 'distribuzzjoni.

39
00:01:48,210 --> 00:01:50,620
Meta I hit Ikteb, tkun taf tara
bl-isfar hawn, tfakkira

40
00:01:50,620 --> 00:01:52,260
dwar liema folder li jien attwalment jużaw.

41
00:01:52,260 --> 00:01:55,870
F'dan il-każ, huwa sensiela twila,
"ubuntu dar pset6 workspace pubbliku."

42
00:01:55,870 --> 00:01:57,500
U li l-aħħar kelma hija x'inhu importanti.

43
00:01:57,500 --> 00:02:01,180
U mbagħad fl-aħħar, apparentement, tiegħi
server issa s jisimgħu fuq il-port 8080.

44
00:02:01,180 --> 00:02:05,860
>> Dak li jien jmiss ser tagħmel hu recall li
fl ID CS50 fil-rokna ta 'fuq tal-lemin

45
00:02:05,860 --> 00:02:09,440
tal-iskrin tiegħek, int ser tara

46
00:02:09,440 --> 00:02:12,860

47
00:02:12,860 --> 00:02:15,080
U fil-fatt, jekk tikklikkja
dan, inti ser tkun whisked bogħod

48
00:02:15,080 --> 00:02:17,090
tab ieħor browser,
li, f'dan il-każ,

49
00:02:17,090 --> 00:02:20,830
se urini l-kontenut
tal tiegħi għeruq servers mill-web.

50
00:02:20,830 --> 00:02:24,770
Fi kliem ieħor, il-fajls li inti tara hawn,
qattus dot HTML, qattus dot JPEG, favicon dot

51
00:02:24,770 --> 00:02:27,690
ICO, bonjour dot HTML,
bonjour dot PHP, u test,

52
00:02:27,690 --> 00:02:29,800

tkun taf tara li kollha ta 'l-
fajls xogħol minħabba l-istaff

59
00:02:49,420 --> 00:02:52,820
soluzzjoni, naturalment, installati
fil CS50 ID tkun kompletament funzjonali.

60
00:02:52,820 --> 00:02:57,090
Allura taħdem eżattament kif tiegħek
soluzzjoni għandha finalment jaħdmu.

61
00:02:57,090 --> 00:03:00,990
>> Sadanittant, jekk immorru lura għall terminal tiegħi
tieqa, fejn I dam il-kmand server,

62
00:03:00,990 --> 00:03:03,410
Avviż dak li l-console ġie qal.

63
00:03:03,410 --> 00:03:07,890
Nara hawn li l-ewwel talba li
I rċeviet kien litteralment tikseb qattus slash

U mbagħad, fl-aħdar dak
is-soluzzjoni tal-persunal għamel

66
00:03:12,600 --> 00:03:14,580
huwa Hi turi lili l-
ewwel linja tal-produzzjoni

li jiftaħ dak il-pakkett virtwali,
fihom dik it-talba get.

70
00:03:21,530 --> 00:03:23,980
U allura aħna nirrispondu għall-
