Ghost: inštalácia v Digital Ocean

Článok o inštalácií Ghost u cloudového providera Digital Ocean

Ghost: inštalácia v Digital Ocean

Prerekvivizity

  1. Doména, napríklad cez Websupport
  2. Účet u Digital Ocean

Vytvorenie virtuálnej mašiny a.k.a Droplet

  1. Vytvoríme nový projekt + New project
  2. V dashboarde projektu klikneme na Create > Droplets
  3. V Marketplace vyhľadáme Ghost on Ubuntu
  4. CPU options volíme Regular Intel with SSD a najlacnejší plán
  5. Región zvolíme Frankfurt
  6. Zašktneme IPv6 a Monitoring
  7. Pridáme SSH kľúč
  8. Droplet pomenujeme ako názov našej domény, v mojom prípade jozefjuris.sk
  9. Zaškrtneme Create backups
  10. Nazáver klikneme na Create Droplet

Update DNS

Nové IPv4 a IPv6 adresy zanesieme do DNSka. Vytvoríme A, AAAA a CNAME pre subdomény. Počkáme kým sa nové záznamy dostanú do sveta.

watch host jozefjuris.sk

Prvé pripojenie na Droplet

ssh root@jozefjuris.sk

Po prvom prihlásení sa spustí skript, ktorý naštartuje MySQL, stiahne ghost-cli a na záver spustí inštaláciu Ghosta. Budete vyzvaní na vyplnenie domény a emailu.

Pár poznámok na záver

v systéme existujú dvaja užívatelia:

  1. ghost: beží pod ním aplikačný server
  2. ghost-mgr: bežný užívateľ, ktorý má možnost ovládať aplikáciu pomocou ghost-cli sudo -i -u ghost-mgr

zo systemd nás zaujímajú tieto služby:

  1. systemctl status ghost_jozefjuris-sk.service
  2. systemctl status nginx.service
  3. systemctl status mysql.service
