Primary LanguageDockerfile

k8s安装rabbitmq集群

一、下载rabbitmq集群插件

# git clone https://github.com/Idiomroot/k8s-rabbitmq.git
# mkdir plugins && cd plugins
# wget https://github.com/rabbitmq/rabbitmq-autocluster/releases/download/0.10.0/autocluster-0.10.0.ez
# wget https://github.com/rabbitmq/rabbitmq-autocluster/releases/download/0.10.0/rabbitmq_aws-0.10.0.ez

二、构建镜像

# cd ../
# docker build -t 172.16.0.14:5000/pointsmart/rabbitmq3.7:v4 .
# docker push 172.16.0.14:5000/pointsmart/rabbitmq3.7:v4 （没有私有harbor可以省略此步骤）

三、生成cookie文件

# sh erlang-cookie.sh

四、配置rbac

# kubectl create -f rabbitmq-rbac.yaml

五、配置service

# kubectl create -f serveice-rabbitmq.yaml

六、创建StatefulSet

# kubectl create -f StatefulSet.yaml

七、如果没有存储类，则直接创建PV和PVC

# kubectl create -f nfs-data.yaml

八、查看已经生成服务

# kubectl get pod -o wide| grep rabbitmq
rabbitmq-0 1/1 Running 0 126m 172.30.28.2 172.16.0.9
rabbitmq-1 1/1 Running 0 126m 172.30.3.2 172.16.0.8
rabbitmq-2 1/1 Running 0 86m 172.30.28.7 172.16.0.9

注意：如果启动后出现报错： 
=INFO REPORT==== 8-Aug-2019::08:09:41 ===
autocluster: (cleanup) No partitioned nodes found.
解决办法：需要将其他两个节点加入到第一个节点中
#kubectl exec -it rabbitmq-xxxxx /bin/bash 
root@rabbitmq-xxxxx:/#rabbitmqctl stop_app
root@rabbitmq-xxxxx:/#rabbitmqctl join_cluster  rabbit@rabbitmq-0
root@rabbitmq-xxxxx:/#rabbitmqctl start_app
若出现节点无法加入集群的问题
root@rabbitmq-xxxxx:/#rabbitmqctl reset
root@rabbitmq-xxxxx:/#rabbitmqctl join_cluster  rabbit@rabbitmq-0
root@rabbitmq-xxxxx:/#rabbitmqctl start_app
