编辑Dockerfile文件,vim Dockerfile-broker
内容:

编辑脚本,vim build-broker.sh
内容:
#!/bin/bash docker build -f Dockerfile-broker -t rmq-broker:4.9.2 .2.3. 启动容器脚本
编辑启动脚本,vim start-broker.sh
内容:
#!/bin/bash docker run -d --name rmq-broker --network rmq-bridge --network-alias rmq-broker -e "JAVA_OPT_EXT=-Xmx512M -Xmx512M -Xmn128M" -p 10909:10909 -p 10911:10911 -p 10912:10912 -v /home/data/rocketmq/broker/broker.conf:/home/rocketmq/conf/broker.conf -v /home/data/rocketmq/logs:/home/rocketmq/logs -v /home/data/rocketmq/store:/home/rocketmq/store rmq-broker:4.9.2 sh bin/mqbroker -c /home/rocketmq/conf/broker.conf -n rmq-namesrv:9876 autoCreateTopicEnable=true3. 配置启动RocketMQ 3.1. 创建RocketMQ存储目录和日志目录
mkdir -p /home/data/rocketmq/{logs,store,broker} && touch /home/data/rocketmq/broker/broker.conf
3.2. 创建网桥docker network create rmq-bridge
3.3. 构建namesrv镜像, 启动namesrv容器对于脚本增加执行权限, chmod +x *.sh
先构建namesrv镜像,./build-namesrv.sh; 启动namesrv容器(必须先启动namesrv,然后启动broker), ./start-namesrv.sh
PS: 网上说Java8和RocketMQ4.8.0启动namesrv容器会报错,我用的Java11和RocketMQ4.9.2没有报错:
可以先试试能不能启动,然后再修改
报错信息:
ubuntu@ubuntu:/usr/local/rocketmq$ /usr/local/rocketmq/bin/runserver.sh: 70: [[: not found
Unrecognized option: -Xlog:gc*:file=/dev/shm/rmq_srv_gc_%p_%t.log:time,tags:filecount=5,filesize=30M
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
报错解释:
Java版本使用的是java8,
由于在linux环境(Ubuntu发行版,其它发行版未知)下, 直接启动mqnamesrv会报错,
具体原因是sunserver.sh第69行中判定java版本的脚本有问题, 导致判定java版本为9以上,进而导致程序进入第70行if else结构中的else分支中,java GC参数无法识别而报错.
这里使用sed将第70行,第75-79行注释掉.
3.4. 构建broker镜像, 启动broker容器解决方案:
在Dockerfile-namesrv文件中增加&& rm -rf rocketmq-${ROCKETMQ_VERSION}
&& cd ${NAMESRV_HOME}/bin
#下边新增两行, 脚本中注释对应代码
&& sed -i ‘70s/^/#/’ runserver.sh
&& sed -i ‘75,79s/^/#/’ runserver.sh
&& sed -i ‘s#-Xms[0-9]+[gm]#-Xms512m#g’ runserver.sh
&& sed -i ‘s#-Xmx[0-9]+[gm]#-Xms512m#g’ runserver.sh
然后构建broker镜像,./build-broker.sh; 启动broker容器(必须先启动namesrv,然后启动broker), ./start-broker.sh
3.5. 查看可以通过docker logs <容器名>查看容器是否报错。
接下来为了便于 *** 作,可以安装RocketMQ-Console
下载地址https://gitee.com/ralph81/rocketmq-console/repository/archive/master.zip
下载文件,修改配置文件(src/main/resources/application.properties)
# 注释这行,不然会报错-端口占用 # server.address=IP # 修改访问上下文,这个也不需要 # server.contextPath=/rocketmq # 修改访问端口号,默认8080 这个端口太常见了 server.port=8099 # name server地址 rocketmq.config.namesrvAddr=宿主机IP:9876
使用maven打包,上传编译后的jar包
4.2. 编辑Dockerfile-console文件FROM java:8 WORKDIR /usr/local/rocketmq-console VOLUME /tmp COPY rocketmq-console-ng-2.0.0.jar ./rocketmq-console.jar ENV JAVA_OPTS "" ENV PORT "" ENV NAMESRV_ADDR "" EXPOSE 8099 ENTRYPOINT ["sh","-c","java $JAVA_OPTS -jar rocketmq-console.jar --server.port=$PORT --rocketmq.config.namesrvAddr=$NAMESRV_ADDR"]4.3. 构建broker镜像脚本
编辑脚本, vim build-console.sh
内容:
#!/bin/bash docker build -f Dockerfile-console -t rmq-console:2.0.0 .4.4. 构建启动容器脚本
编辑脚本,vim start-console.sh
内容:
#!/bin/bash docker run -d -p 8099:8099 --name rmq-console --network rmq-bridge --network-alias rmq-console -e "JAVA_OPTS=-Xms512m -Xmx512m -Xmn128m" -e "PORT=8099" -e "NAMESRV_ADDR=rmq-namesrv:9876" rmq-console:2.0.04.5. 浏览器登陆
