# chmod a+x /usr/bin/docker-compose
2. 查看 docker-compose 版本#
Copy # docker-compose version
三、部署服务#
1. docker-compose.yaml 资源清单#
Copy version: '3'
services:
rabbitmq:
image: rabbitmq:3.8.34-management
hostname: rabbitmq
container_name: rabbitmq
deploy:
resources:
limits:
cpus: '1'
memory: 2G
ports:
- "15672:15672"
- "15692:15692"
- "5672:5672"
# rabbitmq-exporter port
- "9419:9419"
volumes:
- /data/rabbitmq/:/var/lib/rabbitmq
- /etc/localtime:/etc/localtime
restart: always
rabbitmq_exporter:
image: kbudde/rabbitmq-exporter:1.0.0-RC19
container_name: rabbitmq_exporter
environment:
RABBIT_USER: admin
RABBIT_PASSWORD: admin
depends_on:
- rabbitmq
network_mode: "service:rabbitmq"
restart: always
2. 部署服务#
Copy # docker-compose up -d
# docker-compose ps -a
3. 初始化 rabbimq 账号信息#
Copy # cat init_rabbitmq.sh
#!/bin/bash
# reset first node
echo "1、Reset first rabbitmq node."
docker exec rabbitmq /bin/bash -c 'rabbitmqctl stop_app'
docker exec rabbitmq /bin/bash -c 'rabbitmqctl reset'
docker exec rabbitmq /bin/bash -c 'rabbitmqctl start_app'
# add user and userrole
echo "2、Starting to create user."
docker exec rabbitmq /bin/bash -c 'rabbitmqctl add_user admin admin'
echo "3、Set tags for new user."

echo "4、Grant permissions to new user."
docker exec rabbitmq /bin/bash -c "rabbitmqctl set_permissions -p '/' admin '.*' '.*' '.*'"
echo "5、Delete guest user"
docker exec rabbitmq /bin/bash -c "rabbitmqctl delete_user guest"
Copy # bash init_rabbitmq.sh
