Isilondolozi se-squid - ingxenye 2

I-squid akuyona nje insizakalo yommeleli ne-cache kuphela, ingenza okuningi: ukuphatha i-acl (uhlu lokufinyelela), ukuhlunga okuqukethwe, ingenza nokuhlunga kwe-ssl ngisho nakwimodi esobala (indlela yommeleli - ngaphandle kokumisa kuzilungiselelo zommeleli kuziphequluli zazo , kufana nendoda phakathi, akekho owaziyo ukuthi ikhona). Ngakho-ke ngivame ukubona ukuthi amandla agcwele walolu hlelo achithwa kanjani ngokungazi ukuthi ungazilungisa kanjani izingxenye zayo.

Manje into ethokozisayo eyenziwa yi-squid isilondolozi (ngombono wami). Uzongitshela, kungani i-cache? Isizathu silula, ukuphatha kangcono ukusetshenziswa kwejubane lakho ne-bandwidth yinto esemqoka. Cabanga ngokucophelela, abantu abayi-1000 enkampanini yakho bebonisana njalo ngemizuzu emi-5, amakhasi ajwayelekile, i-Google, i-Hotmail, i-Gmail, njll ... ukuze uzolanda izithombe, amabhanela, ukukhangisa, okuqukethwe kwe-html kaninginingi, konke lokhu kumile izinto, cha Zishintsha kaningi, kungcono ukuzigcina zigcinwe kunethiwekhi yangakini futhi zilethe ikhophi oyibheka njengamuva nje kokucutshungulwa okucabangile.

Ungakwenza kanjani? Kulula ngalo musho olandelayo:

refresh_pattern [-i] regex min percent max [options]

Njengoba ngihlala ngisho, ungakholelwa yonke into, ngakho-ke ngikumema ukuthi ufunde emthonjeni osemthethweni. Ngincoma ukuthi ufunde imanuwali yalo musho LAPHA

Isigwebo vuselela_iphethini Kuzohlala kuyilebula lethu ukwengeza amapharamitha amasha kunqolobane.

Okubalulekile, uhlu lwakho lwe-cache kufanele lulandelane, ngoba uma selufana nolokuqala olufana nento, ngeke iqhubeke nokufunda eminye imithetho yakho

Izinkulumo ezijwayelekile zibucayi, ngakho-ke i-flv ayifani ne-FLV, kepha ungakugwema lokhu uma ufisa ngokusebenzisa inketho -i . Ngemuva kwalokho kuzobukeka kanjena ukuvuselela_pattern -i

'Okuncane': yisikhathi (imizuzu) lapho into ezobhekwa njenge "yakamuva noma entsha" futhi uma ingenayo ilebula ecacile yokuthi "iphelelwe yisikhathi". Ngokuzenzakalelayo i-squid incoma ukuthi ibe ngu-0, ngenxa yezizathu zokuthi ezinye izinhlelo zokusebenza ezinamandla zingaziphatha ngendlela exakile, i-blah blah blah emsulwa, ngempela leli nani kufanele libe yinombolo oyithatha njengelusizo futhi elisebenzayo kuzinto ofuna ukuzilondoloza, isibonelo: jpg, imizuzu eyi-1440 (usuku) kubonakala kukuhle kimi, akufani nokuthi izithombe zeposi zishintsha njalo ngemizuzu emi-5 ekhasini.

'Amaphesenti' Kuyiphesenti lobudala bento (kusuka ekuguqulweni kokugcina) okuzobhekwa njenge- «yamuva noma okusha». Ake ngichaze, mhlawumbe ukwenza ukulayisha kabusha okuqhubekayo noma ukuvuselela ukuze ngibone ukulungiswa kokugcina okwenziwe ekhasini lewebhu, i-squid ingacabanga ukuthi ngabe isivele inayo, ithi, i-50% yesikhathi esigcwalisiwe phakathi imiz y max, landa kabusha leyo nto kwi-intanethi bese ikunikeza ikhophi entsha.

'Ubukhulu' umkhawulo ongaphezulu noma olingana no- 'Okuncane' into ibhekwa njenge- «yamuva noma entsha» isikhathi esingakanani, ake sithi isithombe sekhasi elithile sathintwa kanye ngumsebenzisi, leyo nto isivele ifinyelele esikhathini sayo imiz, kepha hhayi i- max, lapho-ke ibuzwa futhi, kuzothunyelwa ikhophi yesilondolozi.

Options:
override-expire
override-lastmod
reload-into-ims
ignore-reload
ignore-no-store
ignore-private
max-stale=NN
refresh-ims
store-stale

Lezi zinketho zenziwa ikakhulu ukungazinaki isimilo esivele sisungulwe ngezilimi nezivumelwano, ukuze kuqinisekiswe ukusetshenziswa kahle kwenqolobane.

override-expire

Iphoqelela isikhathi esincane sento, noma ngabe iseva ithumele isikhathi sokuphelelwa isikhathi esifushane (isibonelo izinto ezinjengekhanda noma i-Cache-Control: max-age). Uma senza lokhu, "isexwayiso" sizovela sisho izinto ezinjengalezi "SIPHUKA izinga le-HTTP" kepha lezo izexwayiso nje esingaziziba. Manje uma isikhathi esithunyelwa yiseva siside lapho-ke i-squid izothatha isikhathi (ukuphela) kweseva

override-lastmod

Iqinisa isikhathi esincane sento, noma ngabe leyo nto isanda kulungiswa kamuva nje.

reload-into-ims

Incazelo emfushane ukuthi ivimbela ukuthi lapho sicindezela inkinobho yokuvuselela noma senza isicelo sokungagcini, i-squid izoletha isilondolozi uma ingazange "ilungiswe kusukela" futhi / noma uma kungekho "izihloko" ekhasini.

ignore-reload

Ziba isenzo sabasebenzisi ukucindezela inkinobho yokulayisha kabusha noma yokuvuselela ikhasi

ignore-no-store

Ziba noma imuphi umthetho kuzihloko ongawugcini, ngokwesibonelo amavidiyo

ignore-private

Ziba noma yimiphi imithetho ezihlokweni zokuqukethwe eziyimfihlo okungafanele ukuthi zigcinwe kunqolobane, isibonelo: okuqukethwe kwe-facebook.

refresh-ims

I-squid ixhumana neseva, ukuqinisekisa ukuthi into yintsha sha yini. Uma ngabe izoletha isilondolozi

store-stale

I-squid izogcina zonke lezo zimpendulo, noma zingenalo usuku lokuphelelwa yisikhathi, lokhu akunakwenzeka ngoba ngokuvamile akunakusetshenziswa futhi. Uma unquma ukuyinika amandla kufanele umemezele i-max-stale = NN

max-stale=NN

Uma ukunike amandla okungenhla, kufanele umemezele isikhathi sokuphila esiphezulu kuleyo mpendulo noma isici. I-squid ayilethi izinto zalesi sitayela kepha ingakuqinisekisa nomthombo

Nalu uhlu lokuthi umbuso we "FRESH" usebenza kanjani ngokuya ngamanani esixoxe ngawo:

• OKULUNGILE uma kuphelelwa yisikhathi> manje, okunye STALE
• STALE uma ubudala> ubuningi
• I-FRESH uma i-lm-factor <phesenti, enye i-STALE
• OKULUNGILE uma uneminyaka <iminithi enye STALE

Nasi isibonelo sokucushwa kwenkampani ethile enesikhala esiningi sediski, imishini emihle kanye ne-bandwidth enhle

cache_mem 8092 MB

Manje i-cache ayikho kwi-hard disk kuphela, futhi singakwazi ukugcina imemori yenqama, leli nani lingelenqubo ngayinye ye-squid, ngakho-ke kufanele uyicabangele lapho usebenzisa abaqondisi kabusha njenge I-squidGuard

maximum_object_size_in_memory 1024 KB

Usayizi omkhulu wento kwimemori izogcinwa i-squid ku-RAM. Ungamemezela futhi ubuncane.

memory_replacement_policy heap GDSF
cache_replacement_policy heap GDSF

Njengoba ukwazi ukubona, enye inqubomgomo yokushintshwa kwenqolobane kwimemori ye-RAM nenye kwi-hard disk. Kunezinqubomgomo ezi-2 i-GDSF ne-LFUDA. Owokuqala ufuna ukwenza ngcono iphesenti lama-cache hits, anezinto eziningi ezincane esandleni, elesibili lifuna okuphambene, ligcina izinto zigcinwe kungakhathalekile usayizi wazo.

Umbuzo engicabanga ukuthi ungibuza wona njengamanje, ngisebenzisa ini? Hhayi-ke, uma ucabanga ukuthi endaweni yakho benza imibuzo eminingi futhi okumbalwa okulandwayo kusebenzisa i-GDSF uma kunalokho benza ukulandwa okuningi futhi kunemibuzo embalwa ye-LFUDA. Ukuthi uma ngincoma i-LFUDA ukuthi uzokwenzani, angazi, ukugcina i-cache ku-1TB yediski, kusebenza kahle.

maximum_object_size 4 MB

Usayizi omkhulu wento okumele ugcinwe ngayo

cache_dir aufs /media/proxy249/cache 100 16 256

Lapho kuzogcinwa khona inqolobane, ukunakwa lapha, kubalulekile ukuthi uma usebenzisa i-ufs, i-aufs noma i-diskd, wonke ama-3 asebenza ngokufana noma kancane, umehluko ukuthi i-aufs ne-diskd isebenza ngezinqubo ezihlukile zokwenza imisebenzi ye-I / O hard disk futhi uvikele ukuthi izinqubo ze-squid zilenga phakathi nale misebenzi, ngokungeziwe i-diskd ungacacisa inani lezintambo ozoba nalo kulo msebenzi. Ngincoma ama-aufs uma uneqembu elihle.

Usayizi 100 (megabytes), ongabeka i-100000 cishe yi-100GB kuya ngokutholakala kwakho. 16 linani lamafolda, kanti ama-256 linani lamafolda amancane. Ungadlala ngawo womabili amanani kuncike ekutheni amadiski akho ashesha kangakanani nokuthi unezinsiza ezingakanani.

cache_swap_low 90
cache_swap_high 95

Lokhu okukhethwa kukho kungamanani wokushintshwa wezinto, yinani eliphansi neliphezulu njenge-watermark ngokusho kweskwidi, lapho lezi zinombolo zingamaphesenti (%), futhi kunqolobane encane kakhulu, u-5% onjengalokhu njengamanje uzoba ake sithi izinto ezingama-300 ngomzuzwana, kepha ezinqolobaneni ezinkulu kakhulu ngabe sikhuluma ngezinkulungwane ze-MB

Yebo, lapho ngikushiya, lokhu okwamanje, phawula futhi ucabangele labo abangitshele ukuthi abakwazi ukugcina nokuhlunga amakhasi we-https (SSL) ku-squid 3.5 noma ngaphezulu, ngizoziletha kuwe kungekudala, hlala ubukele le bhulogi.
