N\u00e4r det g\u00e4ller att f\u00e5 ut mer av WordPress<\/a> Det r\u00e4cker inte att installera ett snyggt WordPress-tema och b\u00f6rja skriva. Tack vare m\u00e5nga WordPress-plugins kan WordPress inte bara ut\u00f6kas med m\u00e5nga funktioner, utan \u00e4ven laddningstiden kan minskas avsev\u00e4rt.<\/p>\n

Som CDN<\/a> \u00e4r en term som anv\u00e4nds f\u00f6r att beskriva ett n\u00e4tverk av regionalt distribuerade servrar som anv\u00e4nds f\u00f6r att l\u00e4gga ut stora mediefiler (videor, bilder, skript). N\u00e4r det g\u00e4ller Youtube kan man till exempel tala om ett CDN, eftersom videorna distribueras p\u00e5 m\u00e5nga servrar \u00f6ver hela v\u00e4rlden och g\u00f6rs tillg\u00e4ngliga via ett inneh\u00e5llsleveransn\u00e4tverk (CDN).<\/p>\n

CDN-principen anv\u00e4nds dock inte bara f\u00f6r videor, utan \u00e4ven f\u00f6r filer.<\/strong>som kan levereras med hj\u00e4lp av ett cachesystem. Detta g\u00e4ller bland annat JPG-, GIF-, JavaScript- och HTML-filer. F\u00f6r att filerna inte ska beh\u00f6va laddas ner fr\u00e5n din egen server kan de ocks\u00e5 lagras i CDN, vilket sparar trafik och serverns resurser samtidigt som webbl\u00e4sarens samtidiga f\u00f6rfr\u00e5gningar maximeras.<\/p>\n

Konfigurera CDN - de f\u00f6rsta stegen<\/h2>\n

F\u00f6r att kunna inr\u00e4tta ett eget CDN m\u00e5ste du g\u00f6ra vissa f\u00f6rberedelser i f\u00f6rv\u00e4g. Liksom i de flesta fall \u00e4r det \u00e4ven h\u00e4r viktigt att k\u00e4nna till sin egen Webbplats<\/a> inklusive SQL-databasen, f\u00f6r om n\u00e5got g\u00e5r fel eller inte fungerar som \u00f6nskat kan den gamla statusen f\u00f6r WordPress-webbplatsen enkelt \u00e5terst\u00e4llas med hj\u00e4lp av s\u00e4kerhetskopian.<\/p>\n

F\u00f6r att se till att CDN:en f\u00f6r WordPress-webbplatsen fungerar smidigt och att det inte blir n\u00e5gra st\u00f6rre avbrott m\u00e5ste viss information inh\u00e4mtas i f\u00f6rv\u00e4g.<\/strong>.<\/p>\n

Det handlar bland annat om att inr\u00e4tta underdom\u00e4nen, best\u00e4mma underdom\u00e4nens absoluta serverv\u00e4g, flytta mediebiblioteksfilerna till underdom\u00e4nen, uppdatera SQL-databasen f\u00f6r WordPress-webbplatsen, justera WordPress-inst\u00e4llningarna och informera s\u00f6kmotorerna om den \u00e4ndrade strukturen.<\/p>\n

F\u00f6rdelar med en CDN\"CDN\"<\/a><\/h2>\n

S\u00e4rskilt webbplatser med stort inneh\u00e5ll har stor nytta av ett n\u00e4tverk f\u00f6r inneh\u00e5llsleverans. Men \u00e4ven mindre WordPress-webbplatser kan dra nytta av f\u00f6rdelarna med den h\u00e4r tekniken. F\u00f6rdelarna med ett CDN ligger i den kortare svarstiden.<\/strong>som beror p\u00e5 det minskade avst\u00e5ndet mellan bes\u00f6kare och server.<\/p>\n

Dessutom sparas trafiken p\u00e5 huvudservern, eftersom den st\u00f6rsta delen av trafiken sker via CDN, vilket inneb\u00e4r en stor avlastning av den egna servern och m\u00f6jlighet till lastdelning.<\/p>\n

Olika alternativ<\/h2>\n

Om ett CDN ska anv\u00e4ndas b\u00f6r man alltid komma ih\u00e5g att det finns tv\u00e5 olika alternativ f\u00f6r att anv\u00e4nda CDN. Det f\u00f6rsta alternativet kallas Customer Origin och inneb\u00e4r att all data finns kvar p\u00e5 leverant\u00f6rens egen server och att leverant\u00f6ren automatiskt synkroniserar den med alla sina servrar \u00f6ver hela v\u00e4rlden.<\/p>\n

Den stora f\u00f6rdelen \u00e4r att data inte beh\u00f6ver kopieras till n\u00e5gon plats och att inga \u00e4ndringar beh\u00f6ver g\u00f6ras i WordPress.<\/p>\n

Den andra varianten kallas CDN-lagring, varvid all data som ska levereras med CDN lagras hos respektive leverant\u00f6r.<\/strong>.<\/p>\n

Den extra lagringen \u00e4r vanligtvis avgiftsbelagd och man m\u00e5ste se till att de data som ska levereras alltid \u00f6verf\u00f6rs till CDN-lagret. WordPress erbjuder olika plugins f\u00f6r detta \u00e4ndam\u00e5l.<\/p>\n

Anv\u00e4nd CDN utan kostnad<\/h2>\n

Cloudflare erbjuder flera alternativ f\u00f6r att anv\u00e4nda ett CDN gratis. Tj\u00e4nsten \u00e4r en komplett l\u00f6sning f\u00f6r webbs\u00e4kerhet och optimering av hastigheten och kan l\u00e4tt anv\u00e4ndas som CDN-tj\u00e4nst.<\/p>\n

F\u00f6r att g\u00f6ra detta installerar du helt enkelt en ny dom\u00e4n p\u00e5 tj\u00e4nsten utan kostnad och riktar DNS-posten till serverns IP. Alla l\u00e4nkar till de statiska filerna p\u00e5 den nya dom\u00e4nen kan sedan \u00e4ndras.<\/p>\n

Fr\u00e5n och med nu Cloudflare<\/a> allt statiskt inneh\u00e5ll gratis, utan dolda kostnader eller begr\u00e4nsningar<\/strong>. M\u00e5nga Webbhotell<\/a> erbjuder ocks\u00e5 Cloudflare gratis i paketen. Sedan har du dessutom Cloudflare Web Application. Brandv\u00e4gg<\/a> och olika professionella funktioner som annars bara ing\u00e5r i f\u00f6retagsversionen.<\/p>","protected":false},"excerpt":{"rendered":"
