I-WordPress isebenzisa kanjani i-Redis ukusheshisa i-plugin ye-cache? I-CWP inika amandla inqolobane ye-Redis

Kungenzeka ukuthi uzwile nge-APC/APCu, Opcache, Xcache, zingasheshisa kakhulu WordPress noma yiluphi uhlobo lweskripthi se-php esisekelwayo.

Kulesi sifundo, ngizokukhombisa ukuthi ungasheshisa kanjani i-WordPress nge-Redis Object Cache, futhi sizoqhubeka nokufaka i-Redis Cache ku-CWP, ngakho-ke ake siqale.

Iyini inqolobane ye-Redis?

• I-Redis isifinyezo se-RE mote DI yesenzo Seseva.
• I-Redis isitolo esisheshayo, esivulekile sedatha yenkumbulo yenani ledatha.
• I-Redis iza nesethi evamile yezakhiwo zedatha yenkumbulo ekuvumela ukuthi udale kalula izinhlobonhlobo zezinhlelo zokusebenza ezingokwezifiso.
• Izimo eziyinhloko zokusetshenziswa ze-Redis zihlanganisa ukugcinwa kwesikhashana, ukuphathwa kweseshini, i-pub/sub, namabhodi wabaphambili.
• I-Redis iyisitolo senani elingukhiye esidume kakhulu namuhla.
• I-Redis inelayisensi ye-BSD, ibhalwe ngekhodi C eyenziwe kahle, futhi isekela izilimi eziningi zokuthuthuka.

Unika amandla kanjani isizindalwazi senqolobane ye-Redis kuphaneli yokulawula ye-CWP?

isinyathelo 1:Iya ku Iphaneli yokulawula ye-CWP

• Khetha "Izilungiselelo ze-PHP" bese "Isishintshi senguqulo ye-PHP";
• Bese ukhetha "inguqulo ye-PHP" ohlwini oludonsela phansi, kunconywa ukuthi ufake inguqulo yakamuva ye-php 7 ▼
• Ngemuva kokuthi ikhasi lilayishwe kabusha uzobona inketho ye-PHP etholakalayo ukuze ifakwe (ibhokisi lokuhlola)

Zulazulela ezansi futhi uthole " redis "bese uyikhetha bese uchofoza" Build ” inkinobho, ngemuva kokuthi inqubo yokwakha kabusha i-php isiqediwe, ungabheka ukuthi i-redis isebenza ngomyalo olandelayo▼

service redis status

Uzothola okukhiphayo kanje (inCentOS Ihlolwe ku-7, i-CentOS 6 inokukhipha okuhlukile njengokuthi "ukugijima")

[root@demo ~]# service redis status
Redirecting to /bin/systemctl status redis.service
● redis.service - Redis persistent key-value database

└─limit.conf

CGroup: /system.slice/redis.service
└─2486 /usr/bin/redis-server 127.0.0.1:6379

Konke kuhamba kahle kuleli phuzu, manje faka umyalo olandelayo ukuze uhlole ukuthi i-php redis ifakiwe yini▼

php -m | grep -i redis

Okukhiphayo kuzoba kanje ▼

[root@demo ~]# php -m | grep -i redis
redis
[root@demo ~]#

Uma okukhiphayo kungu redis , khona-ke konke kuhamba kahle futhi sizoqhubeka futhi sifake ukuhlanganiswa kwe-WordPress ne-Redis.

Ungayenza Kanjani I-Redis Cache Acceleration Plugin ku-WordPress?

isinyathelo 2:Ngaphambi kokunika amandla i-plugin ye-redis-object-cache ku-WordPress, kufanele wp-config.php Engeza izincazelo ezilandelayo efayeleni ▼

define( 'WP_CACHE_KEY_SALT', 'www.chenweiliang.com:' );

• intando www.chenweiliang.com Faka esikhundleni ngewebhusayithi yakho.

Uma ngine-Redis eminingi kuseva eyodwa, ngizilungiselela kanjani ukuze idatha ingahlangani?

Zimbili izindlela.

Indlela yokuqala ukulungisa ama-Redis DB ahlukene kumasayithi ahlukene.

Vele wengeze ukucushwa okulandelayo kufayela lakho le-wp-config.php ukuze amasayithi ahlukene akwazi ukusebenzisa imininingwane ehlukene ye-Redis.

Ungasetha ama-database e-Redis ahlukene ngokunyukayo kusukela ku-0.

define( 'WP_REDIS_DATABASE', 0 );

Indlela yesibili ukuthi i-Redis ayikwazi ukulawulwa futhi i-database efanayo kufanele isetshenziswe.

Ngemuva kwalokho ungangeza usawoti ohlukile kuwo, ukuze kuthi noma usebenzisa i-database efanayo, idatha ngeke idideke ▼

define( 'WP_CACHE_KEY_SALT', 'www.chenweiliang.com:' );

isinyathelo 3:ngena ngemvume ku I-WordPress backend → Iya kokuthi "Ama-plugin" → "Faka Ama-plugin" ▼

• udinga ukungeza lokhuI-plugin ye-WordPress:Redis Object cache

isinyathelo 4:ucabange ukuthi ufake Redis Object cache plugin, manje zulazulela kuzilungiselelo ze-Redis bese uchofoza okuthi "Vumela Inqolobane Yento".

Ngemuva kokuthi i-WordPress inike amandla i-plugin ye-Redis Cache Acceleration, izobonisa "Ixhunyiwe" njengoba kukhonjisiwe ngezansi▼

• siyakuhalalisela!I-WordPress Redis Cache Acceleration Plugin inikwe amandla ngempumelelo!
• Uzoqaphela ukuthi umthwalo manje unciphile futhi isayithi lilayisha ngokushesha kakhulu.

Isitatimende esikhethekile: Uma uhlelo olufakwe ngokuzenzakalelayo lungesiNgisi, isithombe-skrini sithathwa kalulangesiNgisi.

• Kodwa-ke, abanye abantu baseShayina bathi "iwebhusayithi yamaShayina isebenzisa izithombe-skrini zesiNgisi", "imicibisholo yezithombe ihlukile"...
• Kuyabonakala ukuthi laba bantu baseShayina bavinjelwe ngokuphelele ekucabangeni okukhululekile.
• Mhlawumbe ngenxa yokuthi iShayina akulona izwe elivulekile nelikhululekile.Uma kunjalo, kubonakala sengathi ayikho inkululeko yokukhuluma nokufunda isiNgisi eShayina nhlobo?

Ungamisa kanjani i-plugin yokusheshisa inqolobane ye-Redis?

Ngokuvamile, kwanele ukuqala ngokuqondile, noma singaqhubeka silungiselela.

Engeza ukucushwa okulandelayo kufayela lethu le-wp-config.php▼

define('WP_REDIS_MAXTTL', '86400');

Ungahlola kanjani ukuthi i-cache ye-Redis iyasebenza?

Sebenzisa umyalo olandelayo ukuze uhlole ukuthi inqolobane yasendaweni ye-Redis yakhiwe ▼

redis-cli monitor

• Faka iwebhusayithi yakho, vuselela ikhasi, futhi ungabona ukuthi kunokuphuma kwedatha.

I-Redis caching ingase futhi ibangele ama-plugin e-WordPress kanye nokuguqulwa kwetimu ye-WordPress ukuthi kungenzeki.
