RocketMQ 二主二从异步集群部署
2021/7/21 6:10:15
本文主要是介绍RocketMQ 二主二从异步集群部署,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
一、节点规划
第一台机器 192.168.31.103
端口规划:
9876 NameServer1
10910 BrokerA-master
10921 BrokerB-slave
第二台机器 192.168.31.104
端口规划:
9876 NameServer2
10920 BrokerB-master
10911 BrokerA-slave
二、下载
从官网首页最新发布版本进入下载地址
http://rocketmq.apache.org/
从Latest release vx.x.x进入最新版本下载页面
比如 http://rocketmq.apache.org/release_notes/release-notes-4.7.1/
进入:
https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.7.1/rocketmq-all-4.7.1-bin-release.zip
比如:
cd /usr/local/soft wget https://mirror.bit.edu.cn/apache/rocketmq/4.7.1/rocketmq-all-4.7.1-bin-release.zip
三、解压
解压后,把文件夹改个名字
unzip rocketmq-all-4.7.1-bin-release.zip mv rocketmq-all-4.7.1-bin-release rocketmq
在两台机器上都下载、解压好。
在rocketmq/conf目录下,有三种建议配置模式:
2m-2s-async(2主2从异步) —— 本文采用这种
2m-2s-sync (2主2从同步)
2m-noslave (2主)
现在需要修改两台机器上2m-2s-async这个目录中的文件。
配置文件修改之前先备份。
四、配置第一台机器
192.168.31.103的两个配置文件
(1)broker-a.properties
cd /usr/local/soft/rocketmq/conf/2m-2s-async vim broker-a.properties
修改的内容(名字自定义,保持一致,否则不能组成集群)
brokerClusterName=fanger-cluster
增加的内容
#Broker 对外服务的监听端口 listenPort=10910 #是否允许 Broker 自动创建Topic,建议线下开启,线上关闭 autoCreateTopicEnable=true #是否允许 Broker 自动创建订阅组,建议线下开启,线上关闭 autoCreateSubscriptionGroup=true #nameServer地址,分号分割 namesrvAddr=192.168.31.103:9876;192.168.31.104:9876 #存储路径 storePathRootDir=/usr/local/soft/rocketmq/store/broker-a #commitLog 存储路径 storePathCommitLog=/usr/local/soft/rocketmq/store/broker-a/commitlog #消费队列存储路径存储路径 storePathConsumeQueue=/usr/local/soft/rocketmq/store/broker-a/consumequeue #消息索引存储路径 storePathIndex=/usr/local/soft/rocketmq/store/broker-a/index #checkpoint 文件存储路径 storeCheckpoint=/usr/local/soft/rocketmq/store/checkpoint #abort 文件存储路径 abortFile=/usr/local/soft/rocketmq/store/abort
(2)broker-b-s.properties
vim broker-b-s.properties
修改的内容(名字自定义,保持一致,否则不能组成集群)
brokerClusterName=fanger-cluster
增加的内容:
#Broker 对外服务的监听端口 listenPort=10921 #是否允许 Broker 自动创建Topic,建议线下开启,线上关闭 autoCreateTopicEnable=true #是否允许 Broker 自动创建订阅组,建议线下开启,线上关闭 autoCreateSubscriptionGroup=true #nameServer地址,分号分割 namesrvAddr=192.168.31.103:9876;192.168.31.104:9876 #存储路径 storePathRootDir=/usr/local/soft/rocketmq/store/broker-b-s #commitLog 存储路径 storePathCommitLog=/usr/local/soft/rocketmq/store/broker-b-s/commitlog #消费队列存储路径存储路径 storePathConsumeQueue=/usr/local/soft/rocketmq/store/broker-b-s/consumequeue #消息索引存储路径 storePathIndex=/usr/local/soft/rocketmq/store/broker-b-s/index #checkpoint 文件存储路径 storeCheckpoint=/usr/local/soft/rocketmq/store/checkpoint #abort 文件存储路径 abortFile=/usr/local/soft/rocketmq/store/abort
五、配置第二台机器
192.168.31.104的两个配置文件
修改的内容基本一致,主要是注意一下端口号、路径名。
(1)broker-b.properties
cd /usr/local/soft/rocketmq/conf/2m-2s-async vim broker-b.properties
修改的内容(名字自定义,保持一致,否则不能组成集群)
brokerClusterName=fanger-cluster
增加的内容
#Broker 对外服务的监听端口 listenPort=10920 #是否允许 Broker 自动创建Topic,建议线下开启,线上关闭 autoCreateTopicEnable=true #是否允许 Broker 自动创建订阅组,建议线下开启,线上关闭 autoCreateSubscriptionGroup=true #nameServer地址,分号分割 namesrvAddr=192.168.31.103:9876;192.168.31.104:9876 #存储路径 storePathRootDir=/usr/local/soft/rocketmq/store/broker-b #commitLog 存储路径 storePathCommitLog=/usr/local/soft/rocketmq/store/broker-b/commitlog #消费队列存储路径存储路径 storePathConsumeQueue=/usr/local/soft/rocketmq/store/broker-b/consumequeue #消息索引存储路径 storePathIndex=/usr/local/soft/rocketmq/store/broker-b/index #checkpoint 文件存储路径 storeCheckpoint=/usr/local/soft/rocketmq/store/checkpoint #abort 文件存储路径 abortFile=/usr/local/soft/rocketmq/store/abort
(2)broker-a-s.properties
cd /usr/local/soft/rocketmq/conf/2m-2s-async vim broker-a-s.properties
修改的内容(名字自定义,保持一致,否则不能组成集群)
brokerClusterName=fanger-cluster
增加的内容:
#Broker 对外服务的监听端口 listenPort=10911 #是否允许 Broker 自动创建Topic,建议线下开启,线上关闭 autoCreateTopicEnable=true #是否允许 Broker 自动创建订阅组,建议线下开启,线上关闭 autoCreateSubscriptionGroup=true #nameServer地址,分号分割 namesrvAddr=192.168.31.103:9876;192.168.31.104:9876 #存储路径 storePathRootDir=/usr/local/soft/rocketmq/store/broker-a-s #commitLog 存储路径 storePathCommitLog=/usr/local/soft/rocketmq/store/broker-a-s/commitlog #消费队列存储路径存储路径 storePathConsumeQueue=/usr/local/soft/rocketmq/store/broker-a-s/consumequeue #消息索引存储路径 storePathIndex=/usr/local/soft/rocketmq/store/broker-a-s/index #checkpoint 文件存储路径 storeCheckpoint=/usr/local/soft/rocketmq/store/checkpoint #abort 文件存储路径 abortFile=/usr/local/soft/rocketmq/store/abort
六、创建数据目录
第一台机器163执行(只需要执行一次)
mkdir -p /usr/local/soft/rocketmq/store/broker-a /usr/local/soft/rocketmq/store/broker-a/consumequeue /usr/local/soft/rocketmq/store/broker-a/commitlog /usr/local/soft/rocketmq/store/broker-a/index /usr/local/soft/rocketmq/logs /usr/local/soft/rocketmq/store/broker-b-s /usr/local/soft/rocketmq/store/broker-b-s/consumequeue /usr/local/soft/rocketmq/store/broker-b-s/commitlog /usr/local/soft/rocketmq/store/broker-b-s/index
第二台机器164执行(只需要执行一次)
mkdir -p /usr/local/soft/rocketmq/store/broker-a-s /usr/local/soft/rocketmq/store/broker-a-s/consumequeue /usr/local/soft/rocketmq/store/broker-a-s/commitlog /usr/local/soft/rocketmq/store/broker-a-s/index /usr/local/soft/rocketmq/logs /usr/local/soft/rocketmq/store/broker-b /usr/local/soft/rocketmq/store/broker-b/consumequeue /usr/local/soft/rocketmq/store/broker-b/commitlog /usr/local/soft/rocketmq/store/broker-b/index
七、启动两个NameServer
启动第一台机器163的NameServer
nohup sh /usr/local/soft/rocketmq/bin/mqnamesrv >/usr/local/soft/rocketmq/logs/mqnamesrv.log 2>&1 &
启动第二台机器164的NameServer
nohup sh /usr/local/soft/rocketmq/bin/mqnamesrv >/usr/local/soft/rocketmq/logs/mqnamesrv.log 2>&1 &
八、启动Broker
1、启动节点1 163的 broker-a-master
在163上面执行
nohup sh /usr/local/soft/rocketmq/bin/mqbroker -c /usr/local/soft/rocketmq/conf/2m-2s-async/broker-a.properties > /usr/local/soft/rocketmq/logs/broker-a.log 2>&1 &
在虚拟机中可能由于内存不够导致无法启动,日志文件中出现如下错误:
nohup: ignoring input Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000005c0000000, 8589934592, 0) failed; error='Cannot allocate memory' (errno=12) vim /usr/local/soft/rocketmq/bin/runbroker.sh
把8g和4g改成512m和256m
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m"
再次启动。
2、启动节点2 164的broker-a-s
在164上面执行
nohup sh /usr/local/soft/rocketmq/bin/mqbroker -c /usr/local/soft/rocketmq/conf/2m-2s-async/broker-a-s.properties > /usr/local/soft/rocketmq/logs/broker-a-s.log 2>&1 &
3、启动节点2 164的 broker-b-master
在164上面执行
nohup sh /usr/local/soft/rocketmq/bin/mqbroker -c /usr/local/soft/rocketmq/conf/2m-2s-async/broker-b.properties > /usr/local/soft/rocketmq/logs/broker-b.log 2>&1 &
4、启动节点1 163的broker-b-s
在163上面执行
nohup sh /usr/local/soft/rocketmq/bin/mqbroker -c /usr/local/soft/rocketmq/conf/2m-2s-async/broker-b-s.properties > /usr/local/soft/rocketmq/logs/broker-b-s.log 2>&1 &
163上面启动的3个端口:
164上面启动的3个端口:
查看端口启动状态:
netstat -an|grep 109
第一台机器 192.168.31.103
端口规划:
9876 NameServer1
10910 BrokerA-master
10921 BrokerB-slave
第二台机器 192.168.31.104
端口规划:
9876 NameServer2
10920 BrokerB-master
10911 BrokerA-slave
