docker部署rabbitmq集群

# 使用docker 部署rabbitmq需要创建单独的网络，以便于容器之间使用主机名解析

rabbitmq镜像来自于dockerhub： https://hub.docker.com/_/rabbitmq?tab=tags

本次选用镜像版本：rabbitmq:3.8.3-management

# docker pull rabbitmq:3.8.3-management

# 创建rabbitmq私有网络

# docker network create rabbitmqnet

# docker network ls

# 创建节点

# docker run -d \ --name=rabbitmq1 \ -p 5672:5672 \ -p 15672:15672 \ -e RABBITMQ_NODENAME=rabbitmq1 \ -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' \ -h rabbitmq1 \ --net=rabbitmqnet \ rabbitmq:3.8.3-management # docker run -d \ --name=rabbitmq2 \ -p 5673:5672 \ -p 15673:15672 \ -e RABBITMQ_NODENAME=rabbitmq2 \ -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' \ -h rabbitmq2 \ --net=rabbitmqnet \ rabbitmq:3.8.3-management # docker run -d \ --name=rabbitmq3 \ -p 5674:5672 \ -p 15674:15672 \ -e RABBITMQ_NODENAME=rabbitmq3 \ -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' \ -h rabbitmq3 \ --net=rabbitmqnet \ rabbitmq:3.8.3-management

#  组建rabbitmq集群

登陆Rabbitmq的后两个节点，执行命令加入第一个Rabbitmq节点集群

### Disk Node # docker exec rabbitmq2 bash -c \ "rabbitmqctl stop_app && \ rabbitmqctl reset && \ rabbitmqctl join_cluster rabbitmq1@rabbitmq1 && \ rabbitmqctl start_app" ### Ram Node # docker exec rabbitmq3 bash -c \ "rabbitmqctl stop_app && \ rabbitmqctl reset && \ rabbitmqctl join_cluster --ram rabbitmq1@rabbitmq1 && \ rabbitmqctl start_app"

##  退出集群

# docker pull kbudde/rabbitmq-exporter# docker exec rabbitmq3 bash -c \ "rabbitmqctl stop_app && \ rabbitmqctl reset && \ rabbitmqctl start_app"

拉取haproxy镜像

# docker pull haproxy

docker run -d \   --name rabbitmq-haproxy \   -p 1080:80 -p 5677:5677 -p 8001:8001 \   --net=rabbitmqnet \   -v /root/rabbitmq/haproxy-etc:/usr/local/etc/haproxy:ro \   haproxy:latest

haproxy的配置文件如下：

root@node0:~/rabbitmq# cat haproxy-etc/haproxy.cfg # Simple configuration for an HTTP proxy listening on port 80 on all # interfaces and forwarding requests to a single backend "servers" with a # single server "server1" listening on 127.0.0.1:8000 global   daemon   maxconn 256 defaults   mode http   timeout connect 5000ms   timeout client 5000ms   timeout server 5000ms listen rabbitmq_cluster   bind 0.0.0.0:5677   option tcplog   mode tcp   balance leastconn   server rabbit1 rabbitmq1:5672 check inter 2s rise 2 fall 3   server rabbit2 rabbitmq2:5672 check inter 2s rise 2 fall 3   server rabbit3 rabbitmq3:5672 check inter 2s rise 2 fall 3 listen http_front   bind 0.0.0.0:80   stats uri /haproxy?stats listen rabbitmq_admin   bind 0.0.0.0:8001   server rabbit1 rabbitmq1:15672   server rabbit2 rabbitmq2:15672   server rabbit3 rabbitmq3:15672

#  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/

# docker pull kbudde/rabbitmq-exporter

启动rabbitmq实例

# docker run -d --name=rabbitmq1 -p 5672:5672 -p 15672:15672 -e RABBITMQ_NODENAME=rabbitmq1 -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' -h rabbitmq1 --net=rabbitmqnet -p 9090:9090 rabbitmq:3.8.3-management

启动rabbitmq exporter实例

# docker run -d --net=container:rabbitmq1 kbudde/rabbitmq-exporter

获取rabbitmq的metrics

# wget http://localhost:9090/metrics
