Centos7 Kubernetes(K8s) k8s 开发 单服务器部署 rocketmq - Go语言中文社区

Centos7 Kubernetes(K8s) k8s 开发 单服务器部署 rocketmq

这几天对开发服务器中的 k8s和相关模块 进行升级，做个记录

环境，与系统

系统：centos 7.6

内核： 5.1.9-1.el7.elrepo.x86_64

Kubernetes(K8s) 1.14.3

服务器IP：192.168.0.254

服务器IP 说明

如果更改了服务器IP 为其他IP，那么请全局全部替换成你改的IP
fox.风

如何安装 k8s

请看 最近写的一篇文章，

https://blog.csdn.net/fenglailea/article/details/88745642
常用 k8s 命令
https://foxwho.blog.csdn.net/article/details/92137467

服务器资源限制

对CPU,内存都做了限制，请自行针对修改

没有使用持久化存储，这里直接使用宿主机存储，如有需要，请自行增加

目录

请把项目放置到 /www/k8s/foxdev/ 目录下，所有都是基于此目录
或者请看 下面一节的 拉取代码

拉取代码

mkdir -p /www/k8s/
cd /www/k8s/

git clone https://github.com/foxiswho/k8s-nacos-sentinel-rocketmq-zipkin-elasticsearch-redis-mysql.git foxdev

cd foxdev

以下是 独立部署 相关模块

k8s rocketmq 独立部署

rocketmq 采用 server:1主,Broker:1主1从模式

带有 rocketmq-console web 简单管理界面

相关参数说明

端口：

server: 宿主机IP:9876
Broker:(master) 宿主机IP:10909
Broker:(master) 宿主机IP:10911
Broker:(master) 宿主机IP:10912
Broker:(slave) 宿主机IP:10919
Broker:(slave) 宿主机IP:10921
Broker:(slave) 宿主机IP:10922
ui:(console) 宿主机IP:8180

broker中3个端口说明

  1. listenPort=10911 Broker 对外服务的监听端口
  2. haListenPort=10912 haService中使用 默认值为：listenPort + 1
  3. fastListenPort=10909 主要用于slave同步master listenPort - 2

XX-rc.yml文件启动参数autoCreateTopicEnable=true，表示 允许 Broker 自动创建Topic

日志相关目录

执行命令时候，会自动创建 以下7个目录，部署时候要映射 pod内部目录

/www/k8s/foxdev/rocketmq/logs/
/www/k8s/foxdev/rocketmq/logs-b/
/www/k8s/foxdev/rocketmq/logs-b-s/
/www/k8s/foxdev/rocketmq/logs-ui/

/www/k8s/foxdev/rocketmq/store/
/www/k8s/foxdev/rocketmq/store-b/
/www/k8s/foxdev/rocketmq/store-b-s/

logs: server 日志目录
logs-b: Broker(master) 日志目录
logs-b-s: Broker(slave) 日志目录
logs-ui: console 日志目录

store: server store 目录
store-b: Broker(master) store 目录
store-b-s: Broker(slave) store 目录

独立部署 rocketmq 操作

直接执行 rocketmq 目录下 rmq.start.sh 即可


cd ./rocketmq/ && ./rmq.start.sh

大约几分钟后，使用rocketmq或者访问浏览器http://192.168.0.254:8180,即可看到 rocketmq-console的管理界面

http://192.168.0.254:8180

在这里插入图片描述

使用命令查看相关信息

kubectl get svc,pod,cs,rc

或
kubectl get svc

kubectl get pod

kubectl get cs

kubectl get rc

查看pod

kubectl get pod

输出

NAME                 READY   STATUS    RESTARTS   AGE
rmqbroker-0          1/1     Running   0          3h5m

rocketmq-0           1/1     Running   0          3h5m

查看 service

kubectl get svc

输出

在开发服务器上部署成功，有问题的，可以联系我

资源编排文件

后缀为-rc.yml 是 StatefulSet/Pod 文件
后缀为-service.yml 是 service 文件

开头rocketmq 是 rocketmq server
开头broker 是 rocketmq broker
开头broker-s 是 rocketmq broker slave ,其他的是 master

开头ui 是 rocketmq console 简单页面管理
