To create an EMQX cluster to provide MQTT service and keep it as simple as much, we can do it with docker and docker-compose only.<\/p>\n\n\n\n

Create \/volumes\/emqx-data\/<\/code> on each node for persistent storage of configuration. Make sure to give write permissions.<\/p>\n\n\n\n

On the first node (192.168.31.61), create a docker-compose.yaml<\/code> file with content below<\/p>\n\n\n\n

version: '3'\n\nservices:\n  emqx1:\n    image: emqx:5.5.0\n    container_name: emqx1\n    environment:\n    - \"EMQX_NAME=emqx1\"\n    - \"EMQX_HOST=192.168.31.61\"\n    - \"EMQX_NODE_NAME=emqx1@192.168.31.61\"\n    - \"EMQX_CLUSTER__DISCOVERY_STRATEGY=static\"\n    - \"EMQX_CLUSTER__STATIC__SEEDS=[emqx1@192.168.31.61,emqx2@192.168.31.62,emqx3@192.168.31.63]\"\n    network_mode: \"host\"\n    healthcheck:\n      test: [\"CMD\", \"\/opt\/emqx\/bin\/emqx_ctl\", \"status\"]\n      interval: 5s\n      timeout: 25s\n      retries: 5\n    volumes:\n      - \/volumes\/emqx-data\/emqx1_data:\/opt\/emqx\/data<\/code><\/pre>\n\n\n\n
On the second node (192.168.31.62), create a similar docker-compose.yaml<\/code> file with content below<\/p>\n\n\n\n
version: '3'\n\nservices:\n  emqx1:\n    image: emqx:5.5.0\n    container_name: emqx2\n    environment:\n    - \"EMQX_NAME=emqx2\"\n    - \"EMQX_HOST=192.168.31.62\"\n    - \"EMQX_NODE_NAME=emqx2@192.168.31.62\"\n    - \"EMQX_CLUSTER__DISCOVERY_STRATEGY=static\"\n    - \"EMQX_CLUSTER__STATIC__SEEDS=[emqx1@192.168.31.61,emqx2@192.168.31.62,emqx3@192.168.31.63]\"\n    network_mode: \"host\"\n    healthcheck:\n      test: [\"CMD\", \"\/opt\/emqx\/bin\/emqx_ctl\", \"status\"]\n      interval: 5s\n      timeout: 25s\n      retries: 5\n    volumes:\n      - \/volumes\/emqx-data\/emqx2_data:\/opt\/emqx\/data<\/code><\/pre>\n\n\n\n
On the third node (192.168.31.63), similarly<\/p>\n\n\n\n
version: '3'\n\nservices:\n  emqx1:\n    image: emqx:5.5.0\n    container_name: emqx3\n    environment:\n    - \"EMQX_NAME=emqx3\"\n    - \"EMQX_HOST=192.168.31.63\"\n    - \"EMQX_NODE_NAME=emqx3@192.168.31.63\"\n    - \"EMQX_CLUSTER__DISCOVERY_STRATEGY=static\"\n    - \"EMQX_CLUSTER__STATIC__SEEDS=[emqx1@192.168.31.61,emqx2@192.168.31.62,emqx3@192.168.31.63]\"\n    network_mode: \"host\"\n    healthcheck:\n      test: [\"CMD\", \"\/opt\/emqx\/bin\/emqx_ctl\", \"status\"]\n      interval: 5s\n      timeout: 25s\n      retries: 5\n    volumes:\n      - \/volumes\/emqx-data\/emqx3_data:\/opt\/emqx\/data<\/code><\/pre>\n\n\n\n
Enter the folder where the docker-compose.yaml<\/code> file is located, execute docker compose up -d<\/code><\/p>\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n
If nothing goes wrong, you should be able to see a running container with STATUS<\/code> as healthy<\/code>.<\/p>\n\n\n
\n
\"\"<\/a><\/figure><\/div>\n\n\n
By visiting the webpage http:\/\/192.168.31.61:18083 (default credentials: admin\/public), you should be able to see 3 nodes in cluster.<\/p>\n\n\n
\n
\"\"<\/a><\/figure><\/div>\n\n\n
If you need high-availability, you should carry on deploying nginx or HAProxy, or alternatively, utilize load balancers on cloud to distribute traffic to ports on these EMQX nodes.<\/p>\n","protected":false},"excerpt":{"rendered":"
