Environment Variables

Each service has its own .env.local file. The one-click installer generates these automatically; you only edit them for advanced configuration.

medusa-backend (/opt/carphacom/current/medusa-backend/.env)

| Variable | Required | Notes | |---|---|---| | DATABASE_URL | yes | postgres://medusa:<pass>@localhost:5432/medusa_store | | REDIS_URL | yes | redis://:<pass>@localhost:6379 | | JWT_SECRET | yes | 64-char random hex; rotates require re-login | | COOKIE_SECRET | yes | 64-char random hex | | STORE_CORS | yes | Comma-separated list, e.g. https://shop.example.com | | ADMIN_CORS | yes | Same as above for admin | | AUTH_CORS | yes | Same | | MEDUSA_BACKEND_URL | yes | Public URL of the backend (https://shop.example.com) | | WORKER_MODE | optional | shared (default), worker, or server for split deployments | | CARPHACOM_INSTANCE_ID | yes | Generated at install; do not change | | CARPHACOM_MARKETPLACE_URL | optional | Override marketplace URL (default https://carphacom.com) | | SMTP_HOST, SMTP_PORT, SMTP_USER, SMTP_PASS | optional | For transactional email |

nextjs-storefront (/opt/carphacom/current/nextjs-storefront/.env.local)

| Variable | Required | Notes | |---|---|---| | NEXT_PUBLIC_MEDUSA_BACKEND_URL | yes | Public backend URL | | MEDUSA_BACKEND_URL | yes | http://127.0.0.1:9000 for SSR | | NEXT_PUBLIC_MEDUSA_PUBLISHABLE_KEY | yes | pk_... from /admin/publishable-api-keys | | NEXT_PUBLIC_BASE_URL | yes | Public storefront URL | | NEXT_PUBLIC_DEFAULT_REGION | yes | Lowercase ISO country (e.g. ro) | | REVALIDATE_SECRET | yes | Random 48-char hex; required to trigger ISR revalidation | | DATABASE_URL, DATABASE_PASSWORD | yes | For storefront to read CMS plugin/theme data |

Applying changes

After editing any .env.local you must:

pm2 restart all --update-env
pm2 save

--update-env is critical — without it PM2 keeps the old environment.

Generating secrets

openssl rand -hex 32   # for 64-char hex secrets
openssl rand -hex 24   # for 48-char hex secrets

Multi-tenant federation

For tenant instances pointing to a central marketplace:

CARPHACOM_FEDERATION_URL=https://carphacom.com
CARPHACOM_FEDERATION_PK=pk_<the central instance's publishable key>

Without these, the marketplace tab in admin shows local plugins only.
