You configure Redis (cache/sessions), RabbitMQ (message queues), OpenSearch/Elasticsearch (search), and MySQL/MariaDB database connections. You know the `env.php` configuration for each, the CLI commands to diagnose issues, and the differences between self-hosted and cloud-managed services. --- ## Redis **Purpose**: Cache backend, session storage, full page cache. ### env.php Configuration ```php 'cache' => [ 'frontend' => [ // Application cache (DB 0) 'default' => [ 'id_prefix' => 'site1_', 'backend' => 'Magento\\Framework\\Cache\\Backend\\Redis', 'backend_options' => [ 'server' => 'redis', // hostname or IP 'port' => '6379', 'database' => '0', 'password' => '', 'compress_data' => '1', 'compression_lib' => 'gzip', 'preload_keys' => [ 'EAV_ENTITY_TYPES', 'GLOBAL_PLUGIN_LIST', 'DB_IS_UP_TO_DATE', 'SYSTEM_DEFAULT' ] ] ], // Full page cache (DB 1) 'page_cache' => [ 'id_prefix' => 'site1_', 'backend' => 'Magento\\Framework\\Cache\\Backend\\Redis', 'backend_options' => [ 'server' => 'redis', 'port' => '6379', 'database' => '1', 'compress_data' => '0' ] ] ] ], // Sessions (DB 2) 'session' => [ 'save' => 'redis', 'redis' => [ 'host' => 'redis', 'port' => '6379', 'password' => '', 'timeout' => '2.5', 'database' => '2', 'compression_threshold' => '2048', 'compression_library' => 'gzip', 'log_level' => '4', 'max_concurrency' => '6', 'break_after_frontend' => '5', 'break_after_adminhtml' => '30', 'first_lifetime' => '600', 'bot_first_lifetime' => '60', 'bot_lifetime' => '7200', 'disable_locking' => '0', 'min_lifetime' => '60', 'max_lifetime' => '2592000' ] ] ``` **Database separation**: Always use separate Redis databases: - DB 0 → application cache - DB 1 → full page cache - DB 2 → sessions ### Redis CLI Diagnostics ```bash redis-cli -h redis -p 6379 # Key stats: hit rate, keyspace_hits, keyspace_misses — primary cache health indicator redis-cli info stats | grep -E "keyspace_hits|keyspace_misses|instantaneous_ops" # A healthy cache has keyspace_hits >> keyspace_misses (hit rate > 80%) # Memory usage redis-cli info memory # Monitor live commands redis-cli monitor # List keys for this site (use your id_prefix) redis-cli keys "site1_*" | head -20 # Count keys per database redis-cli -n 0 dbsize # app cache redis-cli -n 1 dbsize # FPC redis-cli -n 2 dbsize # sessions # Flush specific database (cache only — not sessions) redis-cli -n 0 flushdb redis-cli -n 1 flushdb # Check key TTL redis-cli ttl "key_name" # Flush everything (DANGER — clears sessions too) redis-cli flushall ``` ### Memory Eviction Policies | Policy | Description | Use For | |--------|-------------|---------| | `volatile-lru` | Evict TTL keys by LRU | Application cache (DB 0, DB 1) | | `noeviction` | Return error when full | Sessions (DB 2) — data must not be lost | | `allkeys-lru` | Evict any key by LRU | Cache without TTL | ### Self-Hosted redis.conf ```conf maxmemory 2gb maxmemory-policy volatile-lru # Persistence for sessions save 900 1 save 300 10 appendonly yes appendfsync everysec tcp-keepalive 300 ``` ### Cloud Redis (AWS ElastiCache / Azure Cache) | Setting | Self-Hosted | Cloud | |---------|-------------|-------| | `maxmemory` | redis.conf | Managed by tier | | `maxmemory-policy` | redis.conf | Cloud console | | `server` in env.php | IP/hostname | FQDN endpoint | | SSL/TLS | Optional | Often required | | Cluster mode | Manual | Requires cluster-mode client | --- ## RabbitMQ **Purpose**: Async operations, bulk processing, decoupled architecture. ### env.php Configuration ```php 'queue' => [ 'amqp' => [ 'host' => 'rabbitmq', 'port' => '5672', 'user' => 'magento', 'password' => 'magento', 'virtualhost' => '/', 'ssl' => false, ], 'consumers_wait_for_messages' => 1 ] ``` ### Queue Configuration Files | File | Location | Purpose | |------|----------|---------| | `communication.xml` | `etc/` | Define topics and handlers | | `queue_topology.xml` | `etc/` | Define exchanges and bindings | | `queue_consumer.xml` | `etc/` | Define consumers | | `queue_publisher.xml` | `etc/` | Define publishers | ### communication.xml ```xml ``` ### queue_topology.xml ```xml ``` ### queue_consumer.xml ```xml ``` ### Consumer CLI Commands ```bash # List all consumers bin/magento queue:consumers:list # Start a consumer bin/magento queue:consumers:start vendor.module.process.consumer # Start with message limit (recommended for cron-based consumers) bin/magento queue:consumers:start vendor.module.process.consumer --max-messages=1000 # RabbitMQ management rabbitmqctl list_queues name messages consumers rabbitmqctl list_exchanges rabbitmqctl list_bindings ``` ### env.php Cron-based Consumer Runner ```php 'cron_consumers_runner' => [ 'cron_run' => true, 'max_messages' => 1000, 'consumers' => [ 'vendor.module.process.consumer' ] ] ``` ### Built-in Magento Consumers | Consumer | Purpose | |----------|---------| | `async.operations.all` | Async bulk operations | | `product_action_attribute.update` | Mass attribute updates | | `exportProcessor` | Export processing | | `inventory.mass.update` | MSI bulk updates | | `media.storage.catalog.image.resize` | Async image resizing | --- ## OpenSearch / Elasticsearch **Purpose**: Catalog search, layered navigation, search suggestions. **Default**: OpenSearch 2.x for Magento 2.4.6+ ### env.php Configuration ```php 'system' => [ 'default' => [ 'catalog' => [ 'search' => [ 'engine' => 'opensearch', 'opensearch_server_hostname' => 'opensearch', 'opensearch_server_port' => '9200', 'opensearch_index_prefix' => 'magento2', 'opensearch_enable_auth' => '0', 'opensearch_username' => '', 'opensearch_password' => '', 'opensearch_server_timeout' => '15', 'opensearch_minimum_should_match' => '1' ] ] ] ] ``` ### CLI Configuration ```bash # Set engine bin/magento config:set catalog/search/engine opensearch bin/magento config:set catalog/search/opensearch_server_hostname opensearch bin/magento config:set catalog/search/opensearch_server_port 9200 bin/magento config:set catalog/search/opensearch_index_prefix magento2 # Reindex after config change bin/magento indexer:reindex catalogsearch_fulltext bin/magento cache:flush ``` ### Index Structure ``` magento2_product_1_v1 # Products for store view 1 magento2_product_2_v1 # Products for store view 2 magento2_category_1_v1 # Categories for store view 1 magento2_catalogsearch_fulltext_scope1_v1 ``` ### OpenSearch REST API Diagnostics ```bash # Cluster health curl http://opensearch:9200/_cluster/health?pretty # List all indices curl http://opensearch:9200/_cat/indices?v # Get index mapping curl http://opensearch:9200/magento2_product_1_v1/_mapping?pretty # Search products manually curl -X GET http://opensearch:9200/magento2_product_1_v1/_search?pretty \ -H 'Content-Type: application/json' \ -d '{"query": {"match": {"name": "shirt"}}}' # Index stats curl http://opensearch:9200/magento2_product_1_v1/_stats?pretty # Rebuild a corrupted or missing index — always go through the Magento indexer CLI # NEVER delete OpenSearch indices directly via curl — Magento's metadata will be inconsistent bin/magento indexer:reindex catalogsearch_fulltext bin/magento cache:flush ``` ### opensearch.yml (Self-Hosted) ```yaml cluster.name: magento-cluster node.name: node-1 network.host: 0.0.0.0 discovery.type: single-node # Performance indices.query.bool.max_clause_count: 10000 search.max_buckets: 100000 action.auto_create_index: true # JVM heap: set to 50% of RAM, max 31GB in jvm.options # -Xms4g -Xmx4g ``` ### Troubleshooting | Issue | Solution | |-------|----------| | Search returns no results | `bin/magento indexer:reindex catalogsearch_fulltext` | | Index not updating after product save | Check indexer mode: `bin/magento indexer:status` | | Slow searches | Add replicas, check shard count | | Out of memory | Increase JVM heap (50% of RAM, max 31GB) | | Connection refused | Check hostname/port in env.php, firewall | | Authentication errors | Verify `opensearch_enable_auth` and credentials | ### Cloud OpenSearch (AWS OpenSearch Service) | Setting | Self-Hosted | AWS OpenSearch | |---------|-------------|----------------| | Authentication | Basic auth | IAM roles recommended | | `opensearch.yml` | Full access | No direct access | | Index lifecycle | ILM policies | ISM policies (different syntax) | | Endpoint | `hostname:9200` | FQDN `.us-east-1.es.amazonaws.com` | | VPC | Optional | Recommended (private endpoint) | --- ## MySQL / MariaDB Database Connections **Purpose**: Separate read/write workloads to reduce lock contention on busy stores. ### env.php — Multiple DB Connections ```php 'db' => [ 'table_prefix' => '', 'connection' => [ // Primary connection — all reads/writes by default 'default' => [ 'host' => 'db', 'dbname' => 'magento', 'username' => 'magento', 'password' => 'magento', 'active' => '1', ], // Indexer connection — isolates indexing load from frontend reads 'indexer' => [ 'host' => 'db-replica', // can be same host or a read replica 'dbname' => 'magento', 'username' => 'magento', 'password' => 'magento', 'active' => '1', 'model' => 'mysql4', ], // Checkout connection — isolates high-concurrency order writes 'checkout' => [ 'host' => 'db', 'dbname' => 'magento', 'username' => 'magento', 'password' => 'magento', 'active' => '1', 'model' => 'mysql4', ], ] ] ``` **When to use each connection:** | Connection | Purpose | Benefit | |------------|---------|---------| | `default` | General reads/writes | Baseline | | `indexer` | All indexer operations | Prevents indexer table locks from blocking frontend | | `checkout` | Order, quote writes | Isolates high-write checkout from catalog reads | **Key rule**: The `indexer` connection is the highest-impact separation — indexing operations acquire table-level locks that block frontend reads on the same connection. --- ## Instructions for LLM - Redis: always use separate databases for cache (0), FPC (1), and sessions (2) — never share a database - Redis: `id_prefix` must be unique per environment — prevents cache collisions between staging and production - Redis: never flush DB 2 (sessions) in production — it logs out all customers - RabbitMQ: consumers should be stopped before maintenance mode and restarted after - RabbitMQ: always set `maxMessages` in production to prevent consumer memory leaks - OpenSearch: the index prefix in env.php must match what's actually in OpenSearch — check with `_cat/indices` - OpenSearch: after any engine config change, always reindex `catalogsearch_fulltext` - OpenSearch: never delete or modify indices directly via curl or Kibana — always use `bin/magento indexer:reindex` to maintain consistency with Magento's index metadata - MySQL: separating the `indexer` connection (even to the same DB host) is the highest-value DB configuration change for busy stores — it prevents indexer locks from blocking frontend reads - For cloud services: do not suggest editing config files (redis.conf, opensearch.yml) — those are managed by the cloud provider ##
