自定义docker-compose启动rocketmq

用于测试时进行rocketmq的批量启动，方便学习使用；

前置命令

mkdir -p /usr/local/soft/rocketmq/mq/conf      #配置文件路径
mkdir -p /usr/local/soft/rocketmq/mq/logs       #mq日志路径
mkdir -p /usr/local/soft/rocketmq/mq/store      #mq数据存储路径
chmod 777 /usr/local/soft/rocketmq/mq/logs   #设置日志路径的权限
docker network create nginx_network #创建docker网络，我这是按照nginx进行创建，如果存在一个公网机，两个内网机，可以通过nginx的公网机进行broker的转发

broker.conf

注意每个配置后面不要有 #号的注释，否则会被直接拼接到brokerName上

#集群的名称 （不要将注释放在每一行的后面，否则会被追加到后面）
brokerClusterName = DefaultCluster
#broker的名称
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH

# 如果出现 com.alibaba.rocketmq.remoting.exception.RemotingConnectException: connect to <172.0.0.120:10909> failed，将下面改成宿主机IP
#brokerIP1 = 127.0.0.1

Dockerfile-rocketmq

这里采用了一个自定义的容器镜像，以官方镜像作为基础，然后添加中文支持

FROM foxiswho/rocketmq:4.8.0
USER root
RUN yum install kde-l10n-Chinese -y && yum install glibc-common -y
RUN localedef -c -f UTF-8 -i zh_CN zh_CN.utf-8
RUN export LANG=zh_CN.UTF-8
RUN echo "export LANG=zh_CN.UTF-8" >> /etc/locale.conf
ENV LANG=zh_CN.UTF-8 LC_ALL=zh_CN.UTF-8
