00:00:00,000 --> 00:00:09,287

2
00:00:09,287 --> 00:00:11,120
DAVID Malan: Allura għal
dan is-sett problema, int

3
00:00:11,120 --> 00:00:13,236
ser jimplimentaw tiegħek
web server stess.

4
00:00:13,236 --> 00:00:16,110
Imxejna sakemm illi inti ma 'ftit ta'
kodiċi iskeletru li gets bdejt,

5
00:00:16,110 --> 00:00:17,818
imma finalment, int
ser jintemm dan

6
00:00:17,818 --> 00:00:19,940
up hekk li hija effettivament
timplimenta l-abbiltà

7
00:00:19,940 --> 00:00:23,980
biex iservu up paġni web, kemm statiku
kontenut u l-kontenut wkoll dinamiku,

8
00:00:23,980 --> 00:00:25,090
via PHP.

9
00:00:25,090 --> 00:00:27,380
>> Ejja tagħti ħarsa, l-ewwel billi
mod tas-soluzzjoni tal-persunal,

10
00:00:27,380 --> 00:00:29,390
lejn dak ir-riżultat finali se tkun.

11
00:00:29,390 --> 00:00:33,420
Jien l-ewwel ser imexxu
CS50 Tilda / pset6 / server

12
00:00:33,420 --> 00:00:36,330
u mbagħad sing p tispeċifika
port u mbagħad numru

13
00:00:36,330 --> 00:00:38,410
bħal 8080, li huwa pjuttost komuni.

14
00:00:38,410 --> 00:00:40,420
U allura l-isem jew
il-passaġġ għall-direttorju

15
00:00:40,420 --> 00:00:43,360
li nixtieq li jużaw bħala l-web
rotta server, fejn kollha tal-fajls

16
00:00:43,360 --> 00:00:44,680
ser jiġi servut up minn.

17
00:00:44,680 --> 00:00:46,180
Jien ser jimxi 'l quddiem u hit Ikteb.

18
00:00:46,180 --> 00:00:49,010
U tkun taf tara fit-test color
hawnhekk li l-web server huwa

19
00:00:49,010 --> 00:00:52,450
użu tad-direttorju pubbliku tiegħi u
huwa jisma fuq il-port 8080.

20
00:00:52,450 --> 00:00:55,300
Issa ejja mur fuq għal web
browser u fil-fatt jipprovaw

21
00:00:55,300 --> 00:00:56,855
li jgħaqqdu din il-websajt.

22
00:00:56,855 --> 00:00:59,230
Avviż fil-qiegħ dritt
lemin ta 'appliance tiegħek,

23
00:00:59,230 --> 00:01:02,040
li hemm kien kollu
din id-darba l-indirizz IP.

24
00:01:02,040 --> 00:01:03,890
Li l-identifikatur uniku
għall-kompjuter tiegħek

25
00:01:03,890 --> 00:01:06,050
li jidentifika hekk
li inti tista 'aċċess

26
00:01:06,050 --> 00:01:08,261
permezz tal-web browser jew xi
numru ta 'għodod oħra.

27
00:01:08,261 --> 00:01:10,760
Allura jien ser imorru quddiem u
jiftħu Chrome fl-appliance

28
00:01:10,760 --> 00:01:19,250
u jien ser iżuru
http://172.16.254.133 u mbagħad

29
00:01:19,250 --> 00:01:20,960
kolon 8080.

30
00:01:20,960 --> 00:01:24,344
U l-tal-kolon importanti għaliex jekk
inti ma jispeċifikawx il-port li jien ukoll

31
00:01:24,344 --> 00:01:26,260
speċifikata fil-kmand
line, int fil-fatt

32
00:01:26,260 --> 00:01:28,390
ser ikunu jitkellem fis
web tal-appliance stess

33
00:01:28,390 --> 00:01:30,850
server imsejħa Apache,
li hija mibnija fis dan.

34
00:01:30,850 --> 00:01:33,610
Imma llum aħna rridu li tiffoka
fuq web server tagħna stess.

35
00:01:33,610 --> 00:01:36,550
>> Allura issa meta I hit Ikteb,
inti ser ikollok avviż li 501

36
00:01:36,550 --> 00:01:38,380
Mhux Implimentati taqa
up għaliex stajt ppruvaw

37
00:01:38,380 --> 00:01:41,000
aċċess għal direttorju,
mhuwiex fajl partikolari.

38
00:01:41,000 --> 00:01:43,980
Tabilħaqq, jekk inti tfittex fuq biex
fuq ix-xellug fil-tieqa terminal tiegħi,

39
00:01:43,980 --> 00:01:46,690
tkun taf tara li filwaqt li
nisma fuq il-port 8080,

40
00:01:46,690 --> 00:01:52,600
l-web server raw talba għal
IKOLLOK / HTTP / 1.1 u allura l-web server

41
00:01:52,600 --> 00:01:56,680
rrispondew, kif isaffru hawn fil
aħmar, ma 'dak 501 Mhux Implimentat.

42
00:01:56,680 --> 00:01:59,270
>> Ħaġa kurjuża għalkemm, hemm ukoll
din it-tieni linja fl-abjad,

43
00:01:59,270 --> 00:02:03,355
IKOLLOK / favicon.ico HTTP / 1.1.

44
00:02:03,355 --> 00:02:06,230
Now I definitely ma tagħmel dan
myself, iżda jirriżulta li Chrome,

45
00:02:06,230 --> 00:02:09,910
simili ħafna ta 'browsers, se
presumptuously jassumi li l-website tiegħek

46
00:02:09,910 --> 00:02:13,170
huwa suppost li jkollu ftit
grafika up icon fil-tab jew li jmiss

47
00:02:13,170 --> 00:02:16,380
għall-address bar, bħal Harvard
crest jew xi ħaġa flimkien dawk il-linji,

48
00:02:16,380 --> 00:02:19,425
u għalhekk huwa biss guessing mill
mod ta 'dan il-fajl isem default,

49
00:02:19,425 --> 00:02:21,800
li inti jista 'jkollhom fajl
bħal dik wisq, li aħna ma.

50
00:02:21,800 --> 00:02:24,650
U hekk 404 Mhux Found gets bżiq lura.

51
00:02:24,650 --> 00:02:26,120
>> Ukoll issa, avviż dan.

52
00:02:26,120 --> 00:02:29,440
B'żieda ma żżur
dan l-indirizz ġewwa

53
00:02:29,440 --> 00:02:34,940
ta 'l-appliance, 172.16.254.133:8080,
imma l-indirizz IP tiegħek, li tkun ċara,

54
00:02:34,940 --> 00:02:35,910
se jkun differenti.

55
00:02:35,910 --> 00:02:39,690
Avviż li jekk immur fuq Mac tiegħi
jew PC tiegħi lill-browser tiegħi stess

56
00:02:39,690 --> 00:02:43,200
u żur dik l-istess URL, I tista '
tara mill-browser preferut tiegħi stess

57
00:02:43,200 --> 00:02:46,340
jekk huwa Chrome jew Firefox
jew IE jew xi ħaġa oħra, eżattament

58
00:02:46,340 --> 00:02:47,550
l-istess riżultati.

59
00:02:47,550 --> 00:02:48,130
>> OK.

60
00:02:48,130 --> 00:02:51,820
Ejja attwalment żur URL thats magħrufa
jeżistu f'dak direttorju pubbliku.

61
00:02:51,820 --> 00:02:56,890
Jiġifieri, l-indirizz IP
kolon 8080 / cat.jpg.

62
00:02:56,890 --> 00:02:57,930
Ikteb.

63
00:02:57,930 --> 00:02:59,470
U hemm, tabilħaqq, hija Cat Happy.

64
00:02:59,470 --> 00:03:03,340
I jaf minn qabel li hemm ukoll
fajl cat.HTLM, hekk jekk I hit Ikteb,

65
00:03:03,340 --> 00:03:04,469
Nara li wieħed ukoll.

66
00:03:04,469 --> 00:03:06,260
U avviż, fil-
Intant, fuq il we xellug

67
00:03:06,260 --> 00:03:08,176
jkollhom mazz sħiħ ta '
outputs aħdar jfissru

68
00:03:08,176 --> 00:03:13,360
li dawn kienu 200 status,
li jfisser li kienu OK.

69
00:03:13,360 --> 00:03:18,294
