Step 1.1: Create Staging Subdomain DNS & Directory<\/h3>\n
A Record<\/code> for staging.example.com<\/code> pointing to your server’s IP. Then create the web directory and copy production files:<\/p>\n# Create staging document root\nsudo mkdir -p \/var\/www\/staging.example.com\n\n# Clone production files using rsync (preserving file permissions)\nsudo rsync -avP --exclude='wp-content\/cache' \/var\/www\/example.com\/public_html\/ \/var\/www\/staging.example.com\/\n\n# Set proper web server ownership\nsudo chown -R www-data:www-data \/var\/www\/staging.example.com<\/code><\/pre>\nStep 1.2: Clone Production Database with MySQL CLI<\/h3>\n
# Create staging database and grant permissions\nmysql -u root -p -e \"CREATE DATABASE wp_staging; GRANT ALL PRIVILEGES ON wp_staging.* TO 'staging_user'@'localhost' IDENTIFIED BY 'StagingSecretPass2026!';\"\n\n# Dump production database and pipe into staging\nmysqldump -u root -p wp_production | mysql -u staging_user -p'StagingSecretPass2026!' wp_staging<\/code><\/pre>\nStep 1.3: Update Staging wp-config.php<\/h3>\n
