【云原生 | Kubernetes 系列】—K8S部署RocketMQ集群（双主双从+同步模式）
版权 本文为云录原创文章，转载无需和我联系，但请注明来自云录 https://www.yunzhuan.site
rocketMQ高可用有很多种方式，比如：单机部署，多主集群，双主双从同步部署，双主双从异步部署，以及多主多从部署。部署集群可按照自己公司的实际情况进行部署。
单机部署：只启动一个rocketMQ实例就可以了，一般常用来本机测试使用。原因：一旦rocketMQ因某些原因挂掉，导致mq无法使用，则我们服务器无法接受信息与消费信息等。
多主集群：只部署mq主节点，无部署从节点。优点：配置简单，单个Master宕机或重启维护对应用无影响，即使机器宕机不可恢复情况下，也有其他主节点进行写入操作，
消息也不会丢（异步刷盘丢失少量消息，同步刷盘一条不丢），性能最高；
双主双从同步：部署四个节点，每个主节点都有一个从节点，主与从节点的信息通过同步的方式进行保存。优点：消息不会丢失，即：主节点挂了后，从节点的消息也不会造成丢失，只不过没法接受新消息，只能消费，但是能保证我消费的消息一定是准确的。缺点：客户端接受服务器响应时间长。可用于消息安全高的场景。
双主双从异步：与双主双从一致，只不过在主从数据传输是通过异步的方式，优点：客户端能快速的接收到服务器的消息，缺点：主节点挂的情况，从节点会丢失一部分消息。可用于允许消息丢失，吞吐量高的情景。
? 创建存储
这里我用ceph,需要自己准备存储

制作rocketmq镜像
[root rocketmqimage]# ll

-rw-rw-r--. 1 root root 32967749 May 15 13:31 rocketmq-all-4.9.4-bin-release.zip
1:解压rocketmq-all-4.9.4-bin-release.zip 将runbroker.sh脚本文件里的内存设置调整小点
unzip rocketmq-all-4.9.4-bin-release.zip
vim rocketmq-all-4.9.4-bin-release/bin/runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g"
2:准备dockerfile
FROM openjdk:8
RUN rm -f /etc/localtime \
&& ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo "Asia/Shanghai" > /etc/timezone
ENV LANG en_US.UTF-8
COPY rocketmq-all-4.9.4-bin-release /usr/local/rocketmq-all-4.9.4-bin-release
RUN mkdir -p /data/rocketmq/store
CMD ["/bin/bash"]
3:制作镜像并上传到Harbor仓库
docker build -t 127.0.0.1/rocketmq/rocketmq-4.9.3:1.0 .
docker push 127.0.0.1/rocketmq/rocketmq-4.9.3:1.0
制作nameserver的image镜像
将上面rocketmq_image目录下的包rocketmq-all-4.9.4-bin-release 拷贝过来
[root nameserver_image]# ll

drwxr-xr-x 6 root root 103 May 15 13:56 rocketmq-all-4.9.4-bin-release
1:准备 namesrv.properties 自定义nameserver的端口号
[root nameserver_image]# cat namesrv.properties
listenPort=20801
2:准备dockerfile
[root nameserver_image]# cat Dockerfile
