Unoda kushandisa mawebhusaiti akawanda eWordPress pane imwe server uye kugonesa Redis object caching, asi une hanya necached data overwriting mumwe nemumwe uye kukonzera front-end errors? Iyi dzidziso inopa gwara rekupedzisira rekugadzirisa Redis kune akawanda maWordPress sites pane imwe server!
Chidzidzo ichi chinodzidzisa nzira mbiri dzekugovera madhatabhesi akasiyana eRedis (0-15) uye Cache Key Salt prefix isolation nekugadzirisa wp-config.php. Nzira idzi dzinogadzirisa zvakakwana data obfuscation uye dzinovandudza zvakanyanya mashandiro emasevha ane concurrency yakawanda. Chinhu chakakosha kuvana vewebhu!
Mazuva mashoma apfuura, shamwari yangu ine webhusaiti yakazvimirira yakanyunyuta kuti mawebhusaiti ake maviri eWordPress anga achiita zvinhu zvisinganzwisisike nguva pfupi yadarika. Mazita ezvinyorwa kubva pawebhusaiti A akaramba achiendeswa kuwebhusaiti B, uye mifananidzo yakachengetwa kubva pawebhusaiti B yaionekwa zvisinganzwisisike muchikamu chemashoko chewebhusaiti A. Ndakabva ndaseka; ingori nyaya yekuti Redis haina kugadzirirwa kuzviparadzanisa nevamwe.
Funga nezvazvo: vanhu vazhinji, mukuedza kuchengetedza mari, vanofarira kuisa mawebhusaiti akawanda eWordPress paseva imwe chete uye kushandisa Redis kuchengetedza ese. Mugumisiro wacho? Mawebhusaiti ese anongoerekana abatana neRedis Database 0, zvichikonzera kusawirirana kwedata. Kana key ye cache yewebhusaiti A ichienderana ne key ye cache yewebhusaiti B, izvozvo zvinokanganisa.
Kutaura chokwadi, ini pachangu ndakawira mumusungo uyu. Pandaiva ndichivaka ruzivo rwemukati, nzvimbo mbiri dzekuyedza dzaive neRedis instance imwe chete, zvichiita kuti macache akwanise kupindirana. Zvakanditorera nguva yakareba kuti ndinzwisise dambudziko racho. Saka, ndine ruzivo rwekutanga rwekugovana munharaunda iyi.
Pfungwa huru yekugadzirisa dambudziko iri ndeyekuzviparadzanisa nevamwe. Data rewebhusaiti yega yega rinogara munzvimbo yaro, pasina kupindirana. Tingaita sei kuti izvi zviparadzaniswe nevamwe? Pane nzira mbiri huru.
Sarudzo 1: Govera madhatabhesi akasiyana eRedis kumawebhusaiti akasiyana
Maitiro ekuisa Redis memory caching muHestiaCP?
Nzira yekutanga, iyo iriyo imwe yekukurudzira kwangu kukuru, ndeyekupa webhusaiti yega yega dhatabhesi reRedis rakasiyana. Redis ine dhatabhesi gumi nematanhatu kubva pakutanga, dzine nhamba kubva pa0 kusvika pa15. Unogona kushandisa webhusaiti A dhatabhesi 0, webhusaiti B unoshandisa Database 1, zvichingodaro. Izvi zvakafanana nekupa webhusaiti yega yega dhiraivha rakasiyana, zvichiita kuti data rive rakasiyana uye kuti data rive rakachena.
Matanho chaiwo ndeaya anotevera: Kutanga, isa plugin inonzi "Redis Object Cache" mu admin panel yewebsite yega yega yeWordPress. Mugadziri ndiTill Krüss, uye iyi plugin ndiyo yakagadzikana uye yakavimbika. Usagonese caching parizvino. Wobva wabatanidza kune sevha kuburikidza neFTP kana SSH, tsvaga faira rewp-config.php mu root directory yewebsite yega yega, uye wedzera mitsara mishoma yekugadziriswa pamusoro pemutsetse "/* Ndizvo zvese, rega kugadzirisa! Unofara kuburitsa. */".
Semuenzaniso, magadzirirwo ewebhusaiti A:
define( 'WP_REDIS_HOST', '127.0.0.1' );
define( 'WP_REDIS_PORT', 6379 );
define( 'WP_REDIS_DATABASE', 0 ); // 用数据库0
define( 'WP_CACHE_KEY_SALT', 'site_a_' ); // 加个独立前缀，双重保险Kune webhusaiti B, ingochinja nhamba yedhatabhesi uye chivakashure:
define( 'WP_REDIS_HOST', '127.0.0.1' );
define( 'WP_REDIS_PORT', 6379 );
define( 'WP_REDIS_DATABASE', 1 ); // 用数据库1
define( 'WP_CACHE_KEY_SALT', 'site_b_' ); // 前缀也要改Nenzira, kana muenzaniso wako weRedis uine password, unofanirwawo kuiwedzera pakugadziriswa kwewebhusaiti yega yega:
define( 'WP_REDIS_PASSWORD', '你的Redis密码' );Mushure mekugadzirisa faira rekugadzirisa, dzokera kuWordPress admin panel yewebhusaiti yega yega , tsvaga "Settings" -> "Redis," uye tinya "Enable Object Cache." Kana zvese zvikafamba zvakanaka, mamiriro acho acharatidza "Connected." Panguva ino, data riri pamawebhusaiti maviri rinoparadzaniswa.
Sarudzo yechipiri: Shandisa ma "prefixes" akasiyana eRedis Key (Salt)
Zvisinei, pane dambudziko randinofanira kukuyambira nezvaro pachine nguva. Kana uine mawebhusaiti anopfuura gumi nematanhatu, kana kuti uri kushandisa sevhisi yeCloud Redis inopa database imwe chete, nzira yekutanga haizoshande. Kana zvakadaro, uchafanira kushandisa nzira yechipiri: uchishandisa ma prefixes akasiyana eRedis Key (Salt).
Maitiro aya anobvumira mawebhusaiti ese kugovera dhatabhesi imwechete yeRedis, asi inosiyanisa data uchishandisa prefix yakasiyana. Muchidimbu, zvakafanana nemunhu wese anogara muchivako chimwe chete, asi furati yega yega ine kero yayo yakasiyana, zvichidzivirira vatyairi vekutumira zvinhu kuti vasaite zvikanganiso.
Nzira yekugadzirisa yakafanana, inosanganisirawo kuwedzera magadzirirwo mu wp-config.php, asi chinhu chikuru ndechekuti WP_CACHE_KEY_SALT inofanira kunge yakasiyana, nepo WP_REDIS_DATABASE inogona kunge yakafanana (kana kusiiwa isina chinhu, default ndeye 0).
Magadzirirwo eWebhusaiti A:
define( 'WP_REDIS_HOST', '127.0.0.1' );
define( 'WP_REDIS_DATABASE', 0 );
define( 'WP_CACHE_KEY_SALT', 'www_siteA_com_' ); // 确保唯一Magadzirirwo eWebhusaiti B:
define( 'WP_REDIS_HOST', '127.0.0.1' );
define( 'WP_REDIS_DATABASE', 0 );
define( 'WP_CACHE_KEY_SALT', 'www_siteB_com_' ); // 确保唯一Mushure mekugadzirisa, ingogonesa kuchengetedza zvinyorwa mu plugin backend.
Matambudziko nemhinduro dzeCommon Redis Configuration
Zvisinei, ndinofanira kutaura pachena kuti kunyange zvazvo sarudzo yechipiri ichichinjika, ine njodzi inogona kuitika. Kana plugin yako ikabvisa Database 0 yese pakubvisa cache, data kubva kune mamwe mawebhusaiti rinogona kukanganiswa zvisirizvo. Saka, kana uine mawebhusaiti gumi nematanhatu kana mashoma, ndinokurudzira zvikuru kushandisa sarudzo yekutanga kuti uve nekuchengetedzwa kwakanyanya.
Munguva yekugadzirisa, unogona kusangana nematambudziko. Semuenzaniso, webhusaiti inogona kuratidza zvikanganiso kana skrini isina chinhu mushure mekuchinja magadzirirwo. Muzviitiko zvakadaro, tanga watarisa syntax yekodhi mu wp-config.php kuti uone kana paine makomasi kana semicolons asipo. Pamusoro pezvo, iva nechokwadi chekuti PHP Redis extension (php-redis) yakaiswa paserver; kana isiriyo, isa kutanga.
Mumwe mubvunzo unowanzo bvunzwa ndewekuti: ndingabvisa sei cache yewebsite chaiyo? Ingodzvanya "Flush Cache" muWordPress admin panel yewebhusaiti yega yega. Kana uri kushandisa nzira yekutanga (databases dzakasiyana), inongobvisa database inoenderana newebsite iripo uye haizokanganisi mamwe mawebhusaiti. Kana uri kushandisa nzira yechipiri (database imwechete, prefixes dzakasiyana), mamwe maplugins anogona kubvisa Database yese 0 panguva yekudzima, saka nzira yekutanga inokurudzirwa kune akawanda mawebhusaiti.
Kugadzirisa Redis kwakafanana nekuchaja mafoni akawanda. Unogona kushandisa charger imwe neimwe pafoni yega yega (Sarudzo 1), kana kuti unogona kushandisa power strip ine switch yakazvimirira yetambo yega yega (Sarudzo 2). Nheyo huru ndeyekuona kuti kuchaja kwakachengeteka uye kudzivirira ma short circuits.
Ndinoyeuka pandakatanga kugadzira mawebhusaiti akawanda, ndaifunga kuti kugadzirisa Redis kwaive nyore—kungochinja ma parameter mashoma, handiti? Asi pakatanga kugadzirwa, matambudziko ese ekuchengetedza data akaonekwa. Ndakazoona gare gare kuti ruzivo rwehunyanzvi runowanzovanzwa munzvimbo idzodzo "dzinoita sedziri nyore".
Tichitarisa kumashure ikozvino, maitiro ekugadzirisa pachawo akanga asina kuoma, asi pfungwa huru yekuparadzanisa yaive yakakosha. Mukugadzira masisitimu, kuparadzanisa chinhu chakakosha pakuona kugadzikana. Kungofanana nekuronga maguta, nzvimbo dzekugara, nzvimbo dzemaindasitiri, nenzvimbo dzekutengeserana dzinofanira kupatsanurwa, zvikasadaro nyonganyonga inogona kuitika.
Izvi zvinoshandawo pakugadziriswa kwehunyanzvi. Webhusaiti yega yega inofanira kuva nenzvimbo yayo yakazvimirira, pasina kukanganisa vamwe. Iyi haisi nyaya yehunyanzvi chete, asiwo pfungwa yekugadzira.
Sezvo waverenga kusvika pari zvino, kana wawana zvichibatsira, ndapota tumira like uye share. Kana uchida kugamuchira nhau dzichangoburwa, unogonawo kunditevera!
Ndatenda nekuverenga chinyorwa changu. Tichaonana nguva inotevera.
