Konfiguro ueb serverin Caddy
Në shtator të 2017, Caddy EULA u ndryshua dhe të gjitha rastet e Caddy të drejtuara nga bizneset dhe faqet e internetit personale që kryejnë tregti kërkojnë një licencë tregtare për binarin e shkarkuar të Caddy. Ky udhëzues ndihmon klientët që duan të instalojnë serverin në internet Caddy në përputhje me EULA-n e re. Në kohën e shkrimit, kur përpiloni Caddy nga burimi dhe krijoni binarin tuaj, nuk kërkohet një licencë me pagesë nëse jeni biznes ose bëni tregti në faqen tuaj personale të internetit. Është e rëndësishme të rishikoni EULA-n më të fundit për pajtueshmërinë përpara se të ndiqni hapat në këtë tutorial.
Karakteristikat:
- Konfigurim i shkurtër, lehtësisht i kuptueshëm
- Ndërtuar me Go
- Prerje e zgjeruar
- Dorëzimi jashtëzakonisht i shpejtë i skedarëve statik
- Mbështetje dinamike e faqes dhe proxy
- Kontrolluesi i konfigurimit të brendshëm
- Binar statik
- Përdor si parazgjedhje shifrat moderne të rekomanduara nga Mozilla
- Zbulim MITM (njeri në mes).
- Mbështetje SNI (treguesi i emrit të serverit).
- Automatik Le të Enkriptojmë gjenerimin/rimarrjen/rinovimin e certifikatës
- Mbështetje OCSP
- Mbështetje për hostet virtualë
- Mbështetje për paraqitjen e Markdown2html
- Mbështetje e integruar HTTP/2, QUIC dhe Websocket
- Balancimi i ngarkesës, proksi i kundërt dhe mbështetje për përfundimin e SSL

Instaloni Caddy Nga Source
Shkarkoni versionin më të fundit të lëshimit të kodit burimor të serverit të uebit Caddy. Kjo nuk përmban shtojca të palëve të treta për Caddy.
go get -u github.com/mholt/caddy/caddy && go get -u github.com/caddyserver/builds && cd go/src/github.com/mholt/caddy/caddy
Opsionale: Nëse keni nevojë për tls.dns.vultrshtojcën dnsproviders të palëve të treta, kopjoni sa vijon. Kjo do të shkarkojë kodin burimor Caddy dhe tls.dns.vultrshtojcën dnsproviders të palëve të treta nëse dëshironi ta përdorni.
go get -u github.com/mholt/caddy/caddy && go get -u github.com/caddyserver/builds && go get -u github.com/caddyserver/dnsproviders/vultr && cd go/src/github.com/mholt/caddy/caddy && sed -i '38i\\t_ "github.com/caddyserver/dnsproviders/vultr"' caddymain/run.go
Përpiloni caddybinarin. Kjo do të marrë më pak se një minutë për tu përpiluar.
