Caching Youtube
Puas rasanya, akhirnya bisa caching youtube (dan yang similar) :D.
Setelah sekian bulan “mangkrak” akhirnya jalan juga walau masih di mesin virtualbox.
Howto ini bukan untuk para pembenci youtube dan googlemap.
Tapi untuk youtube dan googlemap lovers.

Versi yang saya pakai adalah squid-2.7.STABLE3, tidak tahu dukungan untuk versi yang lain.
- buat script untuk manipulasi youtube.
#!/usr/bin/perl $|=1; while (<>) { @X = split; $url = $X[0]; $url =~s@^http://(.*?)/get_video\?(.*)video_id=(.*?)&.*@squid://videos.youtube.INTERNAL/ID=$3@; $url =~s@^http://(.*?)/get_video\?(.*)video_id=(.*?)$@squid://videos.youtube.INTERNAL/ID=$3@; $url =~s@^http://(.*?)/videodownload\?(.*)docid=(.*?)$@squid://videos.google.INTERNAL/ID=$3@; $url =~s@^http://(.*?)/videodownload\?(.*)docid=(.*?)&.*@squid://videos.google.INTERNAL/ID=$3@; print "$url\n"; } - Lalu di squid.conf-nya edit seperti yang dibawah ini:
acl store_rewrite_list url_regex ^http://(.*?)/get_video\? acl store_rewrite_list url_regex ^http://(.*?)/videodownload\? cache allow store_rewrite_list # Had to uncomment this again, because I couln'd login to google mail using IE6 (firefox had no trouble): acl QUERY urlpath_regex cgi-bin \? cache deny QUERY refresh_pattern ^http://(.*?)/get_video\? 10080 90% 999999 override-expire ignore-no-cache ignore-private refresh_pattern ^http://(.*?)/videodownload\? 10080 90% 999999 override-expire ignore-no-cache ignore-private storeurl_access allow store_rewrite_list storeurl_access deny all storeurl_rewrite_program /usr/local/bin/store_url_rewrite
Hasilnya bisa dilihat di access-log, pada saat mengakses video yang sama, akan langsung hit.
# grep youtube access.log | grep TCP_HIT 1214834411.379 735 192.168.1.89 TCP_HIT/200 1604459 GET http://youtube.com/get_video?video_id=2d55B-SiJdM&t=OEgsToPDskKrwAAE_vVIhOqMhPqmPDUQ - NONE/- video/flv 1214834487.090 818 192.168.1.94 TCP_HIT/200 1604459 GET http://youtube.com/get_video?video_id=2d55B-SiJdM&t=OEgsToPDskLGVqEnxKjLEN4DGA3HYGse - NONE/- video/flv 1214836269.353 4383 192.168.1.91 TCP_HIT/200 9533167 GET http://youtube.com/get_video?video_id=i6cKRT12jgw&t=OEgsToPDskKeQxYVvYZ7fgEIW4UNC_U- - NONE/- video/flv 1214836514.802 3757 192.168.1.91 TCP_HIT/200 9533167 GET http://youtube.com/get_video?video_id=i6cKRT12jgw&t=OEgsToPDskIEwsTb26LiGFc96hBUUa9Z - NONE/- video/flv
Satu pesan dari Horacio Herrera Gonzalez, karena basic scriptnya tidak spesifik ke url tertentu, maka :
Warning! This code may match other sites not related to YT or GV.
He he he he, watching your bandwidth.
Karena beberapa user merasa kesulitan untuk mengaplied caching youtube.
Langkah dibawah adalah urutan di server saya.
- Saya pakai distro TSL 3.05, dengan squid squid-2.7.STABLE3

Caching photobucket
Kontribusi apit (Ym-id relative_04), caching untuk photobucket yang banyak di pakai di friendster.
di store_url_rewrite

Update script
Diperkirakan youtube merubah sistem mereka, sekitar quartal pertama tahun 2009.
Akibatnya script diatas sudah tidak berfungsi, untuk mengatasinya perlu diubah script dan beberapa bagian di konfigurasi.
Untung saja sudah ada panduannya di http://wiki.squid-cache.org/ConfigExamples/DynamicContent/YouTube/Discussion
konfigurasi di bawah saya coba dimesin vmware dengan os centos 5.2, juli 2009
Untuk mempermudah saya sertakan squid.conf yang sudah dimodifikasi dan script url rewriternya.

Beberapa hari yl saya download video youtube, barusan download lagi url yang sama, lah kok ngulang dr awal ya? Kalau download lagi pada hari yg sama tetap cache hit. Keliatannya rule refresh_pattern ada yg perlu dicermati nich. PR buat pembaca … :) Soalnya cobanya nun jauh di sana, dari ujung sumatera remote ke server di ujung timur pulau jawa :D …
klo dari pengalaman saya, mungkin dikarenakan squid -z untuk mengaktifkan cache yang saya edit pada squid.conf, dikarenakan saya mencari angka yang pas buat cache agar larinya kenceng. Hanya caching youtube aja yang hilang ketika ketik squid -z, obyek yang lain tetap ada.
Coba aja mas arif buka movie di youtube, metacafe, atau streaming lainnya, sebelum di squid -z, coba mas buka lagi streaming yang udah di cache. Setelah itu squid nya di stop, kemudian ketik squid -z, kemudian aktifkan lagi squid nya, streaming yang udah di cache udah gak ada. Jadi klo pendapat saya, walaupun rule refresh_pattern di gedein sampe bertahun2, kalau udah di squid -z tetap aja streaming dimulai dari awal lagi.
Kalau gak di squid -z, Streaming yang udah dicache tetap ada terus sampai kapanpun. Ini mah pendapat saya lho ya… mohon dikoreksi kalau salah…. Untuk bro human gimana solusinya nih kalau udah di squid -z nih.. pusing euy T_T
mas adi, mas arief, mas materpop3, serta teman2…
udah baca http://wiki.squid-cache.org/ConfigExamples/DynamicContent/YouTube/Discussion paling bawah ? maksudnya patch apa yah ? selama saya menggunakan squid versi 2.7 Stable3 belum dipatch, caching streaming gak ada masalah
Tolong jelasin yah maksudnya apa patch tersebut… thx
Saya persilakan mas arief yang jawab dah :D

Setelah extract source squid, lakukan patch dengan option dry-run untuk tes file diff:
# tar jxf squid-2.7.STABLE6.tar.bz2
# cd squid-2.7.STABLE6
# patch -p0 –dry-run < ../squid.diff
patching file src/client_side.c
Hunk #1 succeeded at 2407 with fuzz 2 (offset 8 lines).
#
Kalau hasil patch dg option –dry-run seperti di atas berarti patch bisa dipakai, patch kedua kalinya dengan menghilangkan option –dry-run:
# patch -p0 < ../squid.diff
patching file src/client_side.c
Hunk #1 succeeded at 2407 with fuzz 2 (offset 8 lines).
#
Setelah itu baru configure lalu make squid.
ini cara ngepatch…
mohon dijelaskan maksud dan tujuannya patch yang mas arif terangkan diatas? sorry banget, gw nubie abezzzz
wah… ternyata squid versi 2.7 memang harus di patch euy, klo versi lain gw lom coba
Makasih banget mas arief….
n buat mas adi, mas arief, serta teman2, jangan bosan2 posting kesini yah klo ada update squid lagi, biar teman2 yang sering mampir kesini gampang klo ada update squid, daripada cari di google, susah n lama nyarinya :D
Bang itu setingan conf nya di psang di squidnya ipcop bisa ga yaa ?
soalnya aku liat setingannya conf nya tuh standart cache alaman site aja nah pengennya sih ada delay pool ma cache video streaming …
IPcop 1.4.21 squidnya 2.7stable6
Secara teori sudah bisa, tinggal di lihat perl-nya sudah support atau belum.
Dear,
Mo tanya mass.. dolo pakai squid waktu masih pakai fedora Sekarang server di ganti sama ipcop kira2 itu configrasi squidnya beda apa sama ? kalau sama kan tinggal copas conf yang lama ke dlm squidnya ipcop.
Mohon penjelasannnya …
Oh ya.. saya pakai ipcop 1.4.21 squid 2.7 stable6
Setingan squid confnya di pasang di squid ipcop bisa tak tuh ?
Hadooohhhh…
udah di patch masih juga loading lagi euy
gw kira bisa seterusnya…
apa lagi nih bro human T_T
Waduw
bro human…
diyoutube ada tulisan kayak gini :
“An error occurred, please try again later.”
klo gak pake perl youtube atau di disable di squid.conf file perl nya, baru jalan, cuma judul tertentu error muncul tulisan itu, kenapa yah ? ada solusi ?
Belum pernah nemuin kasus seperti ini.
Coba di cek di log squid, access dan error log, mungkin ada clue disitu.
udah solved bro
sepertinya ip youtube ada yang persis dengan ip facebook, gw dapet info dari forummikrotik, di squid.conf diisi skrip server_http11 on n http_port ip_proxy:80 act-as-origin http11, dan satu lagi gw pake ubuntu server, cache_dir nya pake type diskd euy, klo pake type aufs masih tetep aja ada error, aneh bener bro, kok beda diskd dengan aufs dalam segi meng cache streaming, kenapa bisa beda bro ? Padahal diskd bagusnya untuk keluarga BSD kan, bisa jelasin diskd dengan aufs bro
mas human… saya udah coba sesuaikan config dan cacheyoutube2.pl (kebetulan saya make squid-2.7.STABLE3). Kok gak ada yang masuk hit, miss terus walaupun udah saya coba buka situs youtube tersebut dari beberapa pc yang berbeda. apa ada perubahan yang terbaru mas… tolong donk update cara mencachenya. terimakasih sebelum nya.
Nb. Apakah squid-2.7.STABLE3 harus di patch agar bisa mencache (squid-2.7.STABLE, karena squid tersebut udah terinstall langsung dari ubuntunya nih)
terimakasih.
ganti repo nya sama repo kermic, disitu sdh squid 2.7 stable6. pake yg lokal biar cpt donlodnya…
saya pake ubuntu 8.10, tp reponya ambil dr ubuntu 9.10 dr ugm
Artikel ini bagus, mungkin yang perlu ditambahkan adalah alat atau tool untuk menganalisa squid cache video youtube. Alat bantu yang saya pakai waktu mengaplikasikan isi artikel ini:
1. youtube-dl, script untuk download video di link youtube. Nanti akan menghasilkan url yg bisa di-query oleh HEAD, wget dan juga squidclient.
2. HEAD ini package lwp-request (perl) untuk mengetahui apakah url yg diperoleh dari langkah 1 di atas ada informasi HIT atau tidak.
3. wget, untuk download video flv dari link yg dihasilkan oleh no 1.
4. squidclient, gunanya untuk menghapus content / video youtube yang telah dicache di lokal.
5. Dari link url yg dihasilkan di atas, bisa difeed-kan ke script cacheyoutube2.pl untuk melihat apakah scriptnya bekerja atau tidak.
Nantilah saya bedah, tapi di blog saya saja ya :).
Sip sip, ditunggu artikel mas …
Soalnya yang bocor sudah ditambal jadi ndak bisa nonton youtube lagi kayak nontok tv. Padahal ada rencana untuk download video youtube master konduktor herbert von karajan, simphony beethoven lengkap.
Betul bung kutukupret dengan cara juga berhasil untuk caching youtube.
Kak… saya mendapat error message sama kayak Bang andik:

Sy install squidnya pake apt-get install squid, ga tau gmn caranya ngompile ulang pake –enable-gnuregex. Tolong dijelaskan step by stepnya. makasih…
Bos human… bisa tolong jelaskan, bagaimana kita bisa tau kalo link youtube selalu di berubah? maap nubi kang :D
di bandingkan saja dengan cache log squid yang lama.
Atau paling gampang terasa pada waktu squid sudah tidak caching lagi.
mas gmana ya kalau kita pakai Clark Connect ? atau sama aja settng ya ?
terima kasih atas infonya
Secara umum untuk semua linux sama.
Pastikan saja clark connect memakai squid 2.7X dan sudah tersedia perl.
sip dah
Bos human… emang itu harus di kompile sendiri ya?
Kalo misal saya pake squid yang dari apt-get install masih bisa ato ngga? Terimakasih..
Takutnya kalau pakai apt-get, fungsi regexnya bermasalah, karena tidak jadi default kompile dari squidnya
Terimakasih kang human, Saya memakai squid 2.7 STABLE6 ga perlu di compile ulang dan ternyata berhasil dengan mulus, sebelumnya saya memakai software videocache yg bayar itu (meski sy dapetnya ga bayar) dan mengalami bug sehingga harus me-request 2 kali, baru bisa ter-cache.
Tapi dengan jampi2 diatas, wuuuuzzz… jadi ngacir kang!
Matur sembah nuwun.. ^^
Sip dah kalau sudah bisa jalan, jangan biasakan memakai barang haram ya … he he he
Mohon Bantuan

#############################################
acl youtube dstdomain .youtube.com
cache allow youtube
## atau as simple just ##
cache allow all
#############################################
## kalau squid belum di-patch tambahkan ##
minimum_object_size 512 bytes
## pastikan maximum_object_size yg sesuai ##
maximum_object_size 2 GB
####################################################################
## Note: script yang ditampilkan human mungkin hanya untuk video youtube lama !!
####################################################################
terimakasih infonya mr x, jadi sekarang hanya se-simple itu ya, pakai squid versi berapa ?
memang betul saya tidak mengupdate script di blog saya.
Sudah tidak ada lagi mesin proxy untuk di oprek.
Sekarang sedang dipaksa maen poip2-an.
