启动haproxy后，可以通过haproxy来访问rabbitmq集群：http://external-ip:8001
获取haproxy的状态：http://external-ip:1080/haproxy?stats
rabbitmq exporter部署
要收集rabbitmq的metrics给prometheus使用的话，可以使用开源的rabbitmq-exporter
参考如下：
https://github.com/kbudde/rabbitmq_exporter
https://hub.docker.com/r/kbudde/rabbitmq-exporter/
拉取镜像
|
1
|
# docker pull kbudde/rabbitmq-exporter |
启动rabbitmq实例
开启9090端口，这个是rabbitmq exporter的默认publish_port
启动rabbitmq exporter实例
|
1
|
# docker run -d --net=container:rabbitmq1 kbudde/rabbitmq-exporter |
获取rabbitmq的metrics
|
1
|
# wget http://localhost:9090/metrics |
