docker-compose部署RocketMq

先看看官网：https://rocketmq.apache.org/zh/docs/4.x/quickstart/03quickstartWithDockercompose

尝试了在docker-compose文件中启动命令位置直接设置jvm内存大小，无法正常启动

command: sh mqbroker  -c /home/rocketmq/rocketmq-4.9.6/conf/broker.conf Xms256m -Xmx256m

尝试在环境变量配置jvm内存

environment:
      - JAVA_OPTS= -Xmx256M -Xms256M -Xmn128M

依然无法正常运行，日志都无法正常查看

[root@lavm-wz4qbabjz9 mq]# docker logs d0
/home/rocketmq/rocketmq-4.9.6/bin/runbroker.sh: line 156:    27 Killed                  $JAVA ${JAVA_OPT} $@

最后想了个办法，先起个镜像，直接修改启动文件，然后打包为镜像

启动nameServer的mqnamesrv 是个脚本，它会使用runserver.sh启动，在runserver.sh中定义了Jvm内存参数

相同的启动borker的mqbroker脚本使用 runbroker.sh，可以修改其中的jvm参数

先拉取官方镜像：

docker pull apache/rocketmq:4.9.6

然后运行起来进入里面修改jvm参数后打包为镜像

docker run -id --name=myrocket apache/rocketmq:4.9.6

进入里面修改jvm参数

docker exec -it myrocket /bin/bash

使用vi 修改 runbroker.sh runserver.sh里的jvm内存配置后，打包容器为新镜像

docker commit myrocket myrocketmq:1.0

准备一个配置文件broker.conf

开放端口9876,10911(borker的端口)，10909(客户端查询具体的数据需要调用的端口，没找到如何设置环境变量，直接开放端口算了)

启动并后台运行

docker compose up -d

关闭并移出

docker compose down

关闭

docker compose stop

重启

docker compose restart
