Docker 安装RocketMQ集群
Docker 安装RocketMQ集群
- 2、总结
首先新建一个工作目录
mkdir -p /usr/local/chen/temp/rocketmq/demo，接下来
RocketMQ相关文件都放在该目录下,下载
rocketmq-all-4.7.0-bin-release.zip文件。在工作目录下载文件。运行
wget https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.7.0/rocketmq-all-4.7.0-bin-release.zip。
如果想换其他版本，直接换版本号即可。然后解压该文件。
unzip rocketmq-all-4.7.0-bin-release.zip。
由于本机是在4核8g内存的虚拟机上配置的，所以需要修改相关配置。这些配置和机器配置有关。读者可以根据自己的机器进行修改。首先修改
runserver.sh文件。运行
vim /usr/local/chen/temp/rocketmq/demo/rocketmq-all-4.7.0-bin-release/bin/runserver.sh。修改默认的配置
JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"为
JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:MetaspaceSize=64m -XX:MaxMetaspaceSize=128m"。修改后如下图所示。
然后修改
runbroker.sh文件。运行
vim /usr/local/chen/temp/rocketmq/demo/rocketmq-all-4.7.0-bin-release/bin/runbroker.sh。修改默认配置
JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
JAVA_OPT="${JAVA_OPT} -XX:+UseG1GC -XX:G1HeapRegionSize=16m -XX:G1ReservePercent=25 -XX:InitiatingHeapOccupancyPercent=30 -XX:SoftRefLRUPolicyMSPerMB=0"
为
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m"
JAVA_OPT="${JAVA_OPT} -XX:+UseG1GC -XX:G1HeapRegionSize=16m -XX:G1ReservePercent=10 -XX:InitiatingHeapOccupancyPercent=30 -XX:SoftRefLRUPolicyMSPerMB=1000"
修改后如下图所示:
然后建立集群需要的配置文件。在根目录建立broker-conf文件夹。运行mkdir -p /usr/local/chen/temp/rocketmq/demo/broker-conf。然后建立两个broker集群需要的配置文件。目录结构如下：
每个文件对应的内容为：
broker0-n0.conf
brokerClusterName = DefaultCluster
brokerName = broker0
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
# dleger
enableDLegerCommitLog = true
dLegerGroup = broker0
dLegerPeers = n0-broker0n0:40911;n1-broker0n1:40911;n2-broker0n2:40911
dLegerSelfId = n0
sendMessageThreadPoolNums = 4
# namesrv的地址和端口，这里设置为虚拟机的IP，以便于让测试机访问
namesrvAddr=192.168.114.135:9876
# 该broker的IP地址，由于测试需要让其他机器访问，因此设置为虚拟机的IP
brokerIP1 = 192.168.114.135
listenPort = 10911
#存储路径
storePathRootDir=/app/data/store
#commitLog存储路径
storePathCommitLog=/app/data/store/commitlog
#消费队列存储路径
storePathConsumeQueue=/app/data/store/consumequeue
#索引存储路径
storePathIndex=/app/data/store/index
#checkpoint文件存储路径
storeCheckpoint=/app/data/store/checkpoint
#abort文件存储路径
abortFile=/app/data/store/abort
其中brokerIP1 = 192.168.114.135配置的是虚拟机的IP，读者需要根据自己的IP进行修改。sendMessageThreadPoolNums = 4因为本机是4核，所以配置为4，读者可以根据自己机器配置进行修改。以下内容大同小异，直接贴源码。
broker0-n1.conf
brokerClusterName = DefaultCluster
brokerName = broker0
brokerId = 0

然后在根目录下新建文件rocketmq-namesrv.dockerfile以构建namrsrv镜像的Dockerfile。运行vim rocketmq-namesrv.dockerfile。源码如下:
rocketmq-namesrv.dockerfile
FROM openjdk:8u212-jre-alpine3.9
LABEL MAINTAINER='cn.edu.njust.chen'
ADD rocketmq-all-4.7.0-bin-release /app/rocketmq
ENTRYPOINT exec sh /app/rocketmq/bin/mqnamesrv -n 127.0.0.1:9876
RUN echo "Asia/Shanghai" > /etc/timezone
EXPOSE 9876
接着构建broker镜像的Dockerfile，根目录下新建文件rocketmq-broker.dockerfile, 运行vim rocketmq-broker.dockerfile，内容如下：
FROM openjdk:8u212-jre-alpine3.9
LABEL MAINTAINER='cn.edu.njust.chen'
ADD rocketmq-all-4.7.0-bin-release /app/rocketmq
RUN echo "Asia/Shanghai" > /etc/timezone
ENTRYPOINT exec sh /app/rocketmq/bin/mqbroker -c /app/data/conf/broker.conf
VOLUME /app/data
最后创建docker-compose文件,在根目录下新建文件docker-compose.yml, 运行vim docker-compose.yml。内容如下：

至此系统需要文件全部创建完毕。目录结构如下：
然后运行docker-compose up启动服务。
服务成功启动。运行docker info查看服务状态。
服务已经全部启动。然后在浏览器输入http://192.168.114.135:8087/#/访问系统即可。
2、总结
书上的代码直接运行绝大部分是对的，但是总有一些软件的更新使得作者无能为力。之前的API是对的，但是之后就废弃了或修改了是常有的事。所以我们需要跟踪源代码。这只是一个小小的问题，如果没有前辈的无私奉献，很难想象我们自己一天能学到多少内容。感谢各位前辈的辛勤付出，让我们少走了很多的弯路！
