Create a network

Create a rabbitmq VPC

# docker network create rabbitmqnet# docker network lsNETWORK ID NAME DRIVER SCOPE65b44ea8847c rabbitmqnet bridge local...

Create a nod

Create three Rabbitmq nodes through the docker command

Note that the same RABBITMQ_ERLANG_COOKIE value is used here

# docker run-d\-- name=rabbitmq1\-p 5672 RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' 15672\-e RABBITMQ_NODENAME=rabbitmq1\-e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ'\-h rabbitmq1\-net=rabbitmqnet\ rabbitmq:3.7-rc-management# docker run-d\-name=rabbitmq2\-p 56735672 rabbitmq2\-e RABBITMQ_NODENAME=rabbitmq2\-e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ'\-h rabbitmq2\-- net=rabbitmqnet\ rabbitmq:3.7-rc-management# docker run-d\ -- name=rabbitmq3\-p 5674 RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' 5672\-p 15674 RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' 15672\-e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ'\-h rabbitmq3\-- net=rabbitmqnet\ rabbitmq:3.7-rc-management

Set up rabbitmq cluster

Log in to the last two nodes of Rabbitmq and execute the command to join the first Rabbitmq node cluster

# 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"

Exit the cluster

# docker exec rabbitmq3 bash-c\ "rabbitmqctl stop_app & &\ rabbitmqctl reset & &\ rabbitmqctl start_app"

Pull haproxy image

Pull haproxy image

# docker pull haproxy

Start haproxy

# cat haproxymurcreate.shroud! / bin/bashdocker run-d\-- name rabbitmq-haproxy\-p 1080 name rabbitmq-haproxy 80-p 5677 name rabbitmq-haproxy 5677-p 8001 name rabbitmq-haproxy 8001\-- net=rabbitmqnet\-v / root/rabbitmq/haproxy-etc:/usr/local/etc/haproxy:ro\ haproxy:latest

The configuration file for haproxy is as follows:

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 127.0.0.1:8000global daemon maxconn 256defaults mode http timeout connect 5000ms timeout client 5000ms timeout server 5000mslisten rabbitmq_cluster bind 0.0.0.015 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 3listen http_front bind 0.0.0.0:80 stats uri / haproxy?statslisten rabbitmq_admin bind 0.0.0.0:8001 server rabbit1 rabbitmq1:15672 server rabbit2 rabbitmq2:15672 server rabbit3 rabbitmq3:15672

After starting haproxy, you can access the rabbitmq cluster through haproxy: http://external-ip:8001

Get the status of haproxy: http://external-ip:1080/haproxy?stats

Rabbitmq exporter deployment

To collect the metrics of rabbitmq for prometheus use, you can use the open source rabbitmq-exporter

References are as follows:

Https://github.com/kbudde/rabbitmq_exporter

Https://hub.docker.com/r/kbudde/rabbitmq-exporter/

Pull the image

# docker pull kbudde/rabbitmq-exporter

Start the rabbitmq instance

The copy code is as follows: # docker run-d-name=rabbitmq1-p 5672 RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' 5672-p 15672 RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' 15672-e RABBITMQ_NODENAME=rabbitmq1-e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ'-h rabbitmq1-- net=rabbitmqnet-p 9090 RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' 9090 rabbitmq:3.7-rc-management

Open port 9090, which is the default PUBLISH_PORT for rabbitmq exporter

Start the rabbitmq exporter instance

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

Get the metrics of rabbitmq

# wget http://localhost:9090/metrics
