Installing Magento

Opterius Panel can install Magento Community Edition using Composer and Adobe's official package repository (repo.magento.com). Because Magento requires authentication with Adobe Commerce Marketplace, you need to provide your Marketplace API keys before installing.

Requirements

An active domain or subdomain on your account
PHP 8.2 or higher with extensions: bcmath, ctype, curl, dom, gd, intl, mbstring, openssl, pdo_mysql, simplexml, soap, xml, xsl, zip, sockets
At least 4 GB disk space (Magento + vendors)
Adobe Commerce Marketplace account with access keys
A server with at least 2 GB RAM (Magento compilation is memory-intensive)

Get Magento Marketplace Keys

Before installing, you need API keys from Adobe Commerce:

Sign in at commercemarketplace.adobe.com
Go to My Profile → Access Keys
Create a new key pair (or use an existing one)
Copy the Public Key (used as username) and Private Key (used as password)

In the sidebar, go to Software → Magento
Click Install Magento
Fill in the form:
- Domain — the domain or subdomain to install on
- Install Path — leave empty for the domain root
- Site Name — your store name
- Admin Username / Password / Email — your Magento admin credentials
- Public Key and Private Key — your Magento Marketplace keys
Click Install Magento

[!WARNING] Magento installation is resource-intensive and takes 5–10 minutes. Do not close the browser — the panel will show a spinner while the install runs. If it times out, the process continues in the background; check back after a few minutes.

The installer:

Writes Magento Marketplace credentials to the server's Composer auth store
Runs composer create-project magento/project-community-edition
Updates Nginx to serve from Magento's pub/ directory
Runs magento setup:install with your database and admin credentials
Compiles dependency injection (setup:di:compile)
Deploys static content (setup:static-content:deploy)
Flushes the cache (cache:flush)

After Installation

Access the Admin Panel

Go to https://yourdomain.com/admin (or the admin URL shown in the success message) and sign in.

Switch to Production Mode

Magento installs in developer mode by default:

cd /home/{username}/{domain.com}
php bin/magento deploy:mode:set production

Configure Cron Jobs

Magento requires cron jobs for indexing, email, and other scheduled tasks. Add them:

php /home/{username}/{domain.com}/bin/magento cron:install

This adds the required entries to the system crontab automatically.

Enable Redis (Recommended)

For better performance, configure Redis as the cache and session backend. Opterius Panel does not auto-configure Redis — refer to the Magento documentation for setup.

Enable SSL

Issue an SSL certificate for your domain, then configure the base URLs in Magento:

php bin/magento config:set web/unsecure/base_url https://yourdomain.com/
php bin/magento config:set web/secure/base_url https://yourdomain.com/
php bin/magento config:set web/secure/use_in_frontend 1
php bin/magento config:set web/secure/use_in_adminhtml 1
php bin/magento cache:flush

PHP Version

Magento 2.4.7+ requires PHP 8.2 or 8.3. Set this before installing:

Go to PHP in the sidebar
Select PHP 8.2 or 8.3 for this domain

Troubleshooting

"Invalid credentials" during Composer download

Your Marketplace keys are wrong. Double-check them at commercemarketplace.adobe.com.

"Out of memory" error during compilation

Increase PHP memory limit for this domain. Go to PHP → Configuration and set memory_limit to at least 2G.

Admin URL shows a 404

Run:

php bin/magento info:adminuri

to find the correct admin URL. Magento appends a random suffix by default.

White screen / 500 error

php bin/magento deploy:mode:set developer
tail -100 var/log/system.log
