内容简介:拉取rabbitmq management镜像若不使用Rabbitmq的management功能,可以拉取镜像:rabbitmq:3.7-rc参考:
拉取rabbitmq management镜像
docker pull rabbitmq:3.7-rc-management
若不使用Rabbitmq的management功能,可以拉取镜像:rabbitmq:3.7-rc
参考: https://hub.docker.com/_/rabbitmq/
创建网络
创建rabbitmq私有网络
# docker network create rabbitmqnet # docker network ls NETWORK ID NAME DRIVER SCOPE 65b44ea8847c rabbitmqnet bridge local ...
创建节点
通过 docker 命令创建三个Rabbitmq nodes;
注意这里使用相同的 RABBITMQ_ERLANG_COOKIE 值
# 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:3.7-rc-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:3.7-rc-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:3.7-rc-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 exec rabbitmq3 bash -c \ "rabbitmqctl stop_app && \ rabbitmqctl reset && \ rabbitmqctl start_app"
拉取haproxy镜像
拉取haproxy镜像
# docker pull haproxy
启动haproxy
# cat haproxy-create.sh #! /bin/bash 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
启动haproxy后,可以通过haproxy来访问rabbitmq集群:
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
# 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:3.7-rc-management
开启9090端口,这个是rabbitmq exporter的默认PUBLISH_PORT
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
