XNUMX. Cache PHP ọzọ (nchekwa APC)

Cache PHP Alternative (APC Cache) bụ ihe mepere emepe maka PHP, ejiri na-echekwa Opcode (faịlụ ihe) koodu etiti PHP.

E kewara cache nke APC ụzọ abụọ:

1. cache sistemu
2. cache data onye ọrụ

A na-eji cache sistemụ na-akpaghị aka:

• Nke a pụtara na APC na-echekwa nsonaazụ nchịkọta nke koodu isi mmalite nke faịlụ PHP wee kpọkuo timestamp ọzọ.
• Ọ bụrụ na ọ kubiebeghị, jiri koodu cache mee ya.
• Cache ndabara bụ 3600 (otu elekere).

Mana nke a ka na-efunahụ ọtụtụ oge CPU.

Ya mere, ị nwere ike ịtọ cache sistemu ka ọ ghara ịla n'iyi na faịlụ php.ini, ma tọọ cache sistemu ka ọ ghara ịnwụ (apc.ttl=0).

Agbanyeghị, ime nke a chọrọ ịmalitegharị sava weebụ (dịka ọmụmaatụ, apache) ka ị gbanwee koodu PHP.

Ugbu a, ule arụmọrụ APC n'ozuzu na-ezo aka na cache nke oyi akwa a;

N'ụzọ nkịtị, Nhọrọ PHP Cache (APC Cache) nwekwara ike ịtụle dị ka ihe ndọtị nchekwa nchekwa,

Ọ bụ ndọtị cache nchekwa data.

XNUMX. eAccelerator

eAccelerator bụ ngwa ngwa PHP na-emeghe ma na-emeghe.

• Nkwalite na caching ọdịnaya dị ike, nke nwere ike melite arụmọrụ caching nke script PHP.
• Ya mere, enwere ike idobe script PHP na steeti achịkọtara iji belata oriri ihe nkesa.
• Ọ na-ebuli scripts iji melite arụmọrụ arụmọrụ, na-abawanye arụmọrụ nke koodu PHP site na ugboro 1-10.
• eAccelerator anaghị akwado PHP5.5 ma ọ bụ karịa.

Dị ka a ghọtara site na ederede:eAccelerator bụ ndọtị ngwa ngwa na PHP.

XNUMX. XCache

XCache bụ ihe nchekwa opcode/optimizer mepere emepe nke na-eme ka arụmọrụ PHP dị na sava ahụ.

• Ị nwere ike izere ịmegharị usoro nchịkọta ahụ site na caching data PHP chịkọtara na ebe nchekwa nkekọrịta
• Ma ị nwere ike iji ihe nchekwa ozugbo chịkọta koodu ahụ iji melite ọsọ.
• Ọ nwere ike na-abawanye ọnụego ọgbọ nke ibe site na nkeji 2 ruo 5 wee belata ibu nkesa.

N'ezie,XCache bụ mgbakwunye ngwa ngwa PHP.

Nke anọ, memcached

Memcached bụ sistemu nchekwa ihe nchekwa ihe na-arụ ọrụ dị elu:

• Ejiri ya na ngwa weebụ dị ike iji belata ibu nchekwa data.
• Ọ na-ebelata ọnụ ọgụgụ nke nchekwa data na-agụ site na caching data na ihe dị na ebe nchekwa, si otú ahụ na-enye ọsọ nke ike, nchekwa data webụsaịtị chụpụrụ.

Enwere ike ịghọta ya site na ederede: mgbasawanye cache ebe nchekwa, a na-ejikarị ya maka sava ụyọkọ, nke a na-ejikarị maka cache kesara.

A na-ewere Memcached dị ka ndọtị cache nchekwa data.

XNUMX. Redis

Redis bụ nchekwa data bara uru dị elu.

• Mpụta nke redis akwụghachila ụgwọ dị ukwuu maka enweghị nchekwa keyalue dị ka memcached.
• N'ọnọdụ ụfọdụ, ọ nwere ike ịkwado ọdụ data mmekọrịta.
• N'ọtụtụ ọnọdụ, a na-ejikarị Redis atụnyere memcached.

Ọtụtụ ndị na-eche na Redis nwere ike dochie memcached kpamkpam, n'ihi na Redis nwere ụdị data bara ụba yana arụmọrụ adịghị n'okpuru memcached:

• Redis echekwala ma ọ bụghị;
• Memcached na redis nwere ha abụọ.

Dị ka m maara, Sina Weibo na ngwaahịa ndị ọzọ na-adabere na Redis, nke a pụrụ ịhụ na ọ dị ike.

Ihe dị iche n'etiti PHP cache na nchekwa data nchekwa ndọtị

1) PHP cache ndọtị:

• eAccelerator, XCache bụ mgbakwunye nchekwa nchekwa PHP.

2) Mgbatị cache nchekwa data:

• Redis, memcached, APC cache bụ nchekwa nchekwa nchekwa nchekwa nchekwa.

(Ọ na-abụkarị mmadụ abụọ kwesịrị ịwụnye otu n'ime ha, enwela anyaukwu)

Mgbe ule ụfọdụ gasịrị, achọpụtara na cache data cache gafere otu ọnụ ụzọ, na arụmọrụ APC adịghị mma dị ka cache mcached.

Ya mere, mgbe ị na-ahọrọ ndọtị cache, ụfọdụ ndị ga-ahọrọ ngwakọta nke xcache + memcached, ma ọ bụ ngwakọta nke xcache + redis.

Ọ bụrụ na njehie emee mgbe ị na-etinye ọtụtụ ihe mgbakwunye cache n'otu oge, a na-atụ aro ka ịwụnye naanị otu ndọtị cache ma wepụ ndị ọzọ.

Nchịkọta ntụle ngwa ngwa PHP

• Site na nnwale, eAccelerator bụ ngwakọta kacha mma nke oge arịrịọ na iji ebe nchekwa, mana eAccelerator anaghị akwado PHP 5.5 ma ọ bụ karịa.
• Site na ule ahụ, ọsọ na ngwa ngwa ngwa ngwa bụ ugboro 3 ngwa ngwa karịa na-enweghị onye na-agba ọsọ.
